Best Tires for Harley-Davidson: Sizes, Load Ratings and Date Codes

Your Harley almost certainly came from the factory on Dunlops. Harley-Davidson and Dunlop have worked together for decades, and the D402, D401 and American Elite are built to Harley's specification and carry the Harley-Davidson approval marking. So the first thing worth knowing is that "should I use the OEM tire" is not really a question about quality - it is a question about whether you want what the bike was developed with.

The second thing is more useful, and almost nobody writes about it: when you buy tires online, the single most important number is not the price or the tread pattern. It is the date the tire was made. Rubber ages whether you ride or not, and owners buying through marketplaces routinely receive stock that has been sitting for years. One buyer's review title puts it exactly: shipped new but old tires almost a decade past the manufactured date.

So this page covers the date code first, then how to read Harley's confusing tire sizes, what load and speed ratings actually mean on a loaded bagger, and what mileage you should realistically expect - with real numbers from owners rather than manufacturer claims. The tires come after that.

The DOT Date Code: Read This Before You Buy Anything

Every tire has a DOT code moulded into the sidewall. The last four digits are what matter: the first two are the week, the last two are the year. A tire stamped 4423 was made in the 44th week of 2023.

Why it matters more than tread depth

Rubber cures and hardens with time regardless of use. A tire that has sat in a warehouse for six years has lost flexibility, grips worse in the wet and is more prone to cracking - even with full tread and no miles on it. This is why tire manufacturers generally recommend replacement around five to six years from the date of manufacture, and why a Harley that does 2,000 miles a year will usually need tires because of age rather than wear.

The marketplace problem

This is where it gets practical. Online sellers move old stock, and Harley tire buyers notice. The reviews on the products below are full of it in both directions - buyers furious at receiving decade-old rubber, and buyers specifically praising a fresh code. Several owners state plainly that tires bought online because of lower prices usually end up being old tires.

Equally telling are the positive ones, because they show what experienced buyers actually check: one American Elite buyer notes a date code of the 44th week of 2022 received in April 2023. A Metzeler ME888 buyer notes a code only three months old. Another writes that the code was less than a year old, so it was really a new tire and not old stock.

What to do about it

• Check the code the moment the tire arrives, before it goes anywhere near a wheel. A mounted tire is not returnable.
• Aim for under a year old. Under two is acceptable. Over three, send it back.
• Buy from sellers who move volume. A tire model that sells hundreds of units a month cannot accumulate old stock the way a slow seller can.
• Ask before ordering if the listing is from a smaller seller. Many will tell you the code.
• Factor it into the price comparison. A cheaper tire that is four years old is not cheaper - you have bought a fraction of its usable life.

None of the competing pages on this subject mention this. It is the single most valuable thing on this page.

How to Read Harley Tire Sizes

Harley uses two different sizing systems, sometimes on the same bike, and this confuses more buyers than any other part of the purchase.

Metric sizes - the modern system

130/90B16 reads as: 130 mm section width, aspect ratio 90 (the sidewall height is 90% of the width), B for bias-belted construction, 16 inch rim.

Alphanumeric sizes - the old system Harley still uses

MT90B16 and MU85B16 come from an older American system. MT90B16 is roughly equivalent to 130/90B16, and MU85B16 is roughly 140/85B16. Roughly, not exactly - and this is why you should fit the size the bike specifies rather than converting and hoping.

The tire size for your model is on the swingarm sticker or in the owner's manual. Use that, not a conversion chart.

Front and rear are different tires

They are not interchangeable, and the tread pattern is directional. A front tire is built to handle steering loads and braking; a rear handles drive and carries most of the weight. Fitting a rear on the front, or mounting a tire backwards, is a real and dangerous mistake.

Common Harley sizes

• Touring front: MT90B16 or 130/60B19 on newer models
• Touring rear: MU85B16, 180/65B16 on newer baggers
• Sportster front: 100/90-19
• Sportster rear: 150/80B16
• Custom bagger front: MH90-21 for the 21 inch wheel

One warning about marketplace listings

Amazon's specification tables for tires are frequently wrong. We found a Dunlop D402 MH90-21 listing whose spec table showed 215/55R21 with a load index of 98 and a Y speed rating - car tire data, on a motorcycle tire. Another showed a load capacity of 77 pounds. Take the size and rating from the product title and the manufacturer, never from Amazon's auto-generated table.

Load and Speed Ratings: The Numbers That Matter on a Bagger

After the size, you will see something like 77H or 81H. The number is the load index, the letter is the speed rating.

Load index

This is the maximum weight the tire can carry, and on a Harley it is not academic. A dressed Touring bike weighs around 900 lb before you add a rider, a passenger and loaded bags. A rear tire rated 77 carries roughly 908 lb; one rated 81 carries roughly 1,019 lb.

Fitting a tire with a lower load index than the bike specifies is genuinely unsafe - it is the tire equivalent of the 350 lb motorcycle jack. Never go below what the manual states. Going higher is fine.

Speed rating

H is 130 mph, V is 149 mph. Almost every Harley tire is H rated, which is far beyond anything you will do on a bagger. The rating matters less for outright speed than as an indicator of construction - it reflects the tire's ability to handle sustained heat.

Bias-ply and radial

Most Harleys run bias-ply or bias-belted tires - the B in MT90B16 or 130/90B16. Bias construction gives the stiffer sidewall that suits a heavy cruiser and copes with the load. Some later models are designed for radials.

Do not mix constructions. Running a radial front with a bias rear, or vice versa, changes how the bike steers in a way you will not like and the manufacturers advise against it. Fit what the bike specifies, front and rear as a pair.

What Mileage Should You Actually Expect?

Manufacturer claims are optimistic. Here is what owners of the tires on this page actually report, which is more useful and considerably less flattering.

• Dunlop D401 front, 100/90-19 on a Sportster: 24,000 to 28,500 miles. The standout figure here, and it makes sense - a light bike and a front tire that does not transmit drive.
• Dunlop D402 front MH90-21: 13,000 to 15,000 miles per set, with one owner reporting four sets with no cupping.
• Dunlop American Elite front 130/60B-19 on a bagger: 10,000 to 11,000 miles.
• Dunlop American Elite whitewall rear 180/65B16: 10,000 to 12,000 miles.
• Kenda K671 front: around 6,000 miles.

What this tells you

A rear tire on a loaded Touring bike lasting 10,000 to 12,000 miles at $300 or more is the normal cost of running a bagger, not a defect. Amazon's own review summaries for several of these tires note that durability receives mixed feedback, and the honest reading is that heavy bikes eat rear tires.

The budget end is where the maths gets interesting. A Kenda at $86 doing 6,000 miles costs roughly the same per mile as a Dunlop at $170 doing 12,000 - except you spend twice as much time getting tires fitted, and you accept worse wet grip in between. One Kenda owner is blunt about the trade: they do not do rain well.

Why rears wear faster than you expect

A Harley rear tire carries most of the weight, transmits all the drive, and on a cruiser spends most of its life on the flat centre of the tread going in a straight line. That is why cruiser rears square off rather than wearing evenly, and why the last few thousand miles feel vague when you tip into a corner.

Tire Pressure on a Harley

The most consequential free thing you can do, and the most commonly neglected.

Harley specifies different pressures for solo riding and for riding loaded or two-up, and the difference is significant - typically several psi at the rear. The figures are on the swingarm sticker or in the manual, and they are for the bike, not the tire. The number moulded on the tire sidewall is the maximum the tire can take, not what you should run.

• Check cold, before riding. A warm tire reads several psi high and you will end up underinflated.
• Underinflation is what destroys tires. It builds heat, wears the shoulders, makes the bike feel vague and is the main cause of premature failure on heavy bikes.
• Overinflation wears the centre strip, reduces the contact patch and makes the ride harsh.
• Check weekly. Tires lose about 1 psi a month on their own, and more in cold weather.
• Reset it when the load changes. If you set solo pressures and then load the bags and add a passenger for a trip, you are running underinflated for the whole trip.

Best Tires for Harley-Davidson

Sixteen tires grouped by what the bike is. Every one is currently available and checked, with the size, load and speed rating taken from the product title and the manufacturer rather than Amazon's spec table.

Remember that front and rear are sold separately and are different tires. And check the date code the day it arrives.

Touring and Bagger Tires

Heavy bikes, high loads, long distances. Load index matters most here, and expect 10,000 to 12,000 miles from a rear.

Sportster Tires

Lighter bike, and the mileage figures show it - the D401 front regularly passes 24,000 miles.

Budget Tires

Real savings up front, with a real trade in wet grip and mileage. Honest about both below.

Whitewall Tires

A style choice with a real premium attached - expect to pay noticeably more than the blackwall equivalent of the same tire.

21-Inch Front Tires

For custom baggers running the big front wheel.

When to Replace a Harley Tire

Tread depth

Wear bars sit in the tread grooves and become flush with the surface at the legal minimum. If you can see a continuous band of smooth rubber across the wear bars, the tire is finished. Do not wait for the bars on a rear that has already squared off - handling deteriorates well before the legal limit.

Age

Five to six years from the date code, regardless of tread remaining. This is the one that catches out low-mileage bikes, and it is why the date code section is at the top of this page.

Damage that ends a tire immediately

• A sidewall puncture or cut - sidewalls cannot be repaired, ever
• A puncture in the tread larger than about a quarter inch
• Any bulge or blister, which means the internal structure has separated
• Cracking in the sidewall or between the tread blocks - dry rot
• Riding it flat for any distance, even briefly

Plugs and patches

Most motorcycle tire manufacturers do not endorse repairs at all, and a plug on a motorcycle carries far more risk than on a car - you have two contact patches, not four, and a rear blowout at speed on a heavy bike is not survivable in the way a car's is. A plug is a way to get home, not a repair.

Replace in pairs, or at least in sets

Front and rear wear at very different rates, so you will not always change both. But do not run a new rear against a front that is nearly finished - the handling mismatch is real, and you will be doing the job again in a few thousand miles anyway.

Harley Tire Brands

Dunlop

The factory choice, and the reason nine of the sixteen tires here are Dunlops. Harley-Davidson and Dunlop developed these tires together and they carry the Harley approval marking. The D402 is the long-running Touring tire, the D401 covers Sportsters, and the American Elite is the newer Touring tire with a broader size range. Dunlop's US-made tires have a strong reputation; be aware some sizes are produced elsewhere.

Michelin

The main challenger, and the comparison Google itself surfaces for this search is Dunlop D402 against Michelin Commander 3. Michelin's pitch is longer life and better wet performance, and the Commander III is the tire most often cross-shopped against the OEM Dunlop. The Scorcher range was developed specifically with Harley for Softail and Sportster models. Note the recurring owner report of a hum or vibration through the grips on the Commander III - not universal, but it comes up.

Metzeler

The ME888 Marathon Ultra is the mileage specialist - riders who want the most distance from a rear tire tend to end up here. One thing to know: current production is from Brazil rather than Germany, and at least one owner reported their fitter raising concerns about that. Judge on the reviews rather than the badge.

Shinko

The budget option with a genuine following. The 777 series covers most Harley sizes at roughly half the Dunlop price and has huge review counts - over 800 ratings on some sizes, which is more feedback than most premium tires here. Made in China. Expect shorter life and less wet grip; for a rider doing modest annual mileage the economics work.

Kenda

The cheapest option here at around $86. Around 6,000 miles and, in one owner's words, they do not do rain well. Reasonable for a bike that gets ridden occasionally in good weather, not for a commuter or a tourer.

Avon

The Cobra Chrome is the other name that comes up in Harley tire discussions, aimed at riders who want a premium alternative to the OEM Dunlop.

Harley Tires - FAQs

Conclusion

Three things decide whether you got this right.

The date code. Check it the day the tire arrives, before it is mounted. Under a year is what you want, over three goes back. This single habit protects you from the most common and least discussed problem with buying tires online, and no amount of brand choice compensates for four-year-old rubber.

The size and the load index. Take both from the swingarm sticker or the manual, and take the tire's specification from the title and the manufacturer rather than from a marketplace spec table that may be showing car tire data. Never fit a lower load index than the bike calls for.

Honest expectations on mileage. A rear on a loaded bagger doing 10,000 to 12,000 miles is normal, not a fault. If that is the maths you dislike, the answer is a mileage-focused tire like the Metzeler, not a cheaper tire - because at the budget end you are buying fewer miles and worse wet grip at the same cost per mile.

Beyond that: if your bike came on Dunlops and you were happy, buy Dunlops - it is the tire the chassis was developed around. If you want longer life, look at the Metzeler. If you want better wet weather performance and do not mind cross-shopping the OEM, the Michelin is the tire Google's own summary compares the Dunlop against. And keep the pressures right, because that does more for both grip and tire life than the choice between any two tires on this page.
