Looking for dirt bike tires? Rocky Mountain ATV/MC carries over 100 off-road tires for a variety of bikes and riding preferences. Use the filters on the left-hand side of the screen to narrow our selection down by terrain type, tire size, brand and price. You can also enter your motorcycle’s make, model and year at the top to specifically identify tires that will fit it.
Need additional help in finding the right tire? Check out our tips and info below. We want to make sure that you have everything you need to purchase the right tire for you.
When it comes to buying dirt bike tires, the main thing you want to focus on is the terrain type you expect to ride on. Street motorcycles basically have to worry about one type of terrain: asphalt. Dirt bikes, on the other hand, are designed to traverse numerous types of terrain: rocky trails, forest paths, loamy soil, dirt roads, sand, mud, motocross tracks, slickrock and a lot more (and that’s not even counting if your bike is street legal and will also see asphalt).
There are three primary types of dirt bike tires: soft terrain, intermediate terrain and hard terrain. By choosing the one that best describes your type of riding, you can get a tire that will perform well for you.
The primary difference between these three types of tires is the tread pattern. Soft terrain tires have wider-spaced lugs. This allows the tread to penetrate soft soil, increasing the overall rubber contact but also allowing the tire to somewhat “scoop” the softer terrain. Hard terrain tires, on the other hand, must get as much rubber as possible to the terrain’s surface. For this reason, they typically have narrower-spaced lugs. As you might expect, intermediate terrain tires lie in-between.
So which type of tire should you choose? If you don’t already feel confident that you can match up a tire type to your type of riding, here are a few tips:
The rubber compound is also very important. Soft rubber grips the terrain better, therefore providing superior traction. Hard rubber compounds aren’t as grippy, but they typically last a lot longer.
Of course, there are also specialty tires as well. If you ride exclusively in the sand, soft terrain tires are nice, but quality paddle tires are best. The difference is that while some sand tires (particularly paddle tires) work excellently in sand, they don’t always work well at all on other types of terrain. Soft terrain tires, on the other hand, work fine in the sand, but they also work well on other types of soft terrain as well.
Trials tires are a must for trials bikes, but they can also be used on traditional dirt bikes as well. If you ride exclusively on hard terrain, you might find that trials tires give you even better traction than standard hard terrain tires.
If your bike is street legal and you plan on riding on the road as well, make sure you pick up a set of DOT-approved tires.
To make sure you get the longest life out of your tires as possible, use the correct tire pressure. Overinflated or underinflated tires will wear faster and can also be more prone to accidents. Check your owner’s manual for the correct psi.
Don’t forget to get the right size. Check your owner’s manual to find out the recommended tire size. All modern dirt bike tires utilize a three-number system to indicate size, such as this: 80/100x21.
So a size of 80/100x21 is a tire designed for a 21-inch rim that is 80 mm wide and 80 mm tall (100% of the width).
Some sizes will also indicate ply construction. Radial tires include the letter R after the second number. While radial tires are common for street bikes, many dirt bike tires still use bias tires, which do not include a letter in the tire size. (If the tire size includes the letter B, that means it’s bias belted. You won’t see this ply construction on pure dirt tires, but you might see them on a few dual sport tires.)
Sometimes additional information is also included. A fourth number combined with a letter indicates the load and speed ratings. The number/letter combination is actually a code, so you’ll have to compare it to our load index and speed ratings charts.
We make it easy for you to find the right tire, and we always carry an extensive selection of dirt bike tires at low prices. With our emphasis on customer-centric programs and support, there’s no better solution than Rocky Mountain ATV/MC.

I ride trails and single track, not motocross. The AT81s gave a very compliant ride and absorbed hits without deflection better than any tire I have used. It also offered great traction in mud and ever snow banks I had to ride through. The only downside it they wear quickly. I recommend them!Read All Reviews

First ride with these tires was 4 days after a heavy rain in SoCal. Excellent traction - can tell that's what they were designed for. However, after the trails dried out 2 weeks later, I was sliding all over the place and washed out on trails I've been riding for years. Tires are for soft terrain, not meant for hard by any means.Read All Reviews

I run a tubliss system and was under the mistaken impression that I could run 0 psi in this tire. First the good: At 0 psi this tire is absolutely amazing. I ride nothing but steep, wet, muddy rocks and this tire is perfect for that application. I was unable to find a line that I could not take. I purposely stopped on steep slippery rock gardens just to see if a zero run up line could be taken. Every time I was able to start and immediately transition into a standing position and carry my momentum. Now the bad: At 0 psi in those conditions I only made it 50 miles before the rim had sliced a hole in the side wall about 6" long. I would absolutely recommend this tire, but I would say that 5 psi is probably the minimum.Read All Reviews

I've been running these tires for years and once in a while I will try some other tire but I keep coming back. Tough, long lasting, solid traction. They used to be pretty inexpensive but not anymore.....still worth it!Read All Reviews
