Dirt Bike Tires

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.

Terrain Type

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:

  • If you find yourself in sand, mud or looser soil, consider a soft terrain tire.
  • If you frequent the motocross track or ride trails with varying conditions, consider an intermediate terrain tire.
  • If you ride almost exclusively on packed soil or slickrock, consider a hard terrain tire.
  • If you tend to ride on a wide variety of terrain types and don’t focus on just one, consider an intermediate terrain tire.

Rubber Compound

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.

Specialty Tires

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.

Air Pressure

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.

Tire Size

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.

  1. The first number (80) indicates the tire width, measured in millimeters.
  2. The second number (100) is the tire height from bead to centerline, expressed as the width/height aspect ratio.
  3. The third number is the rim diameter, measured in inches.

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.

    Biggest negative, they are not DOT approved.

    This tire hooks up better than expected on dry fire roads and at the prepped MX track. I have the matching rear on my YZ450F and they exceeded my expectations.

    Works great for me and my style/terrain

    I adore this tire. It’s my sweetheart. Terrain is everything. This tire works well for me in Utah single track and rocky loose climbs. When new it went very well in open sand dunes riding but I haven’t been back since it’s been worn down. It’s now worn to the point I’m losing traction (25% left) but it’s actually still performing well enough. I know I’m down to nubs yet i don’t see a problem yet. Note that I run tubliss usually about 8 psi.

    Best tire I have used. The tread is deep. Big lugs. The tire last a long time. A big plus!! 120 is taller and wider. So it really raises the rear end up.

    This is a great tire, good price too.

    I,ve used this tire amd found it works great for varied terrain, cant go wrong for motocross. This tire hooks ip everyware except blue groove, will chunk in rocky terrain; however, it is not unpredictable in hard pack. Works great in mud and sand. Easy to mount. This is the only tire I use except on pure hardpack.
