Nothing is quite as exciting as getting a new set of ATV tires (except picking up a new quad itself, of course). Tires are such an essential part of your machine that changing them out can alter its characteristic handling. Plus, there’s no denying that some tires give your four wheeler a pretty mean look. When it’s time for you to go shopping for tires, Rocky Mountain ATV/MC is your source. We literally got our start by selling ATV tires, and 30 years later, we’re still the experts. We carry many of the top styles and brands, and we always strive to provide phenomenally low prices.
Do you ride lonely mountain trails, tear up the local MX track, or shred sand at the dunes? Regardless of your terrain of choice, we’ve got tires that will suit you well. We have options that excel in sand, mud, rocks or hard terrain – and many of them cross over into other types as well, giving excellent performance across multiple terrain types.
One of the most essential characteristics of any off-road tire is the tread pattern. The height, width and spacing of the lugs all define how the tire handles in different terrains. For example, wide lugs excel on soft surfaces. Tall, wide lugs can allow your machine to dig through deep mud. Short, tight lugs are often good for hard surfaces like tracks. And of course, you can’t forget about the unique design of each tire’s tread pattern. Many brands spend countless hours in the R&D of a tire’s tread pattern; some are proprietary designs that offer unique handling characteristics you simply can’t get with alternatives. Of course, everyone’s needs are different, so we carry a variety of ATV tires to make sure that you can find something that works well with your specific needs.
We also carry either bias or radial construction tires. In fact, you can filter the options on this page to only show either bias or radial; just check the boxes in the left sidebar. There are advantages and disadvantages for both construction types. Radial tires generally offer better performance at higher loads or speeds. They also don’t wear out as quickly as bias tires. However, bias tires typically come at a lower price, so you can afford to try out different options more frequently. They also have better impact resistance and sidewall puncture resistance – and they’re a lighter weight. That’s why even though radial tires have taken over the auto industry, there are still a lot of off-road riders who choose bias. We have plenty of options for either type, so it doesn’t matter what your preference is.
Another important item to consider when shopping for tires for your ATV is the ply rating. Most of the tires we carry are 4-ply or 6-ply. Both offer a decent weight/durability ratio. However, we also have a few 2-ply tires which can be used for certain track-racing applications. We have tires rated at 8-ply or even 12-ply as well. These are heavy tires which require quads with sufficient power to turn them, but they are pretty heavy duty tires. In fact, 12-ply tires are sometimes marketed as run-flat tires, and they can have great use in some intense off-road races.
You also have many different sizing options. You can enter your machine’s make, model and year into the dropdown menu to narrow the selection down, or you can match up the sizes yourself. Whether you want to match up your tire’s size exactly or experiment a little with the tire height or width to alter its handling, we’ve got options for you. (Of course, don’t experiment too much – your machine is designed for a specific range of tire sizes, after all.)
The first thing is that my tires came in very fast. But when it came to selecting a tire, the more i read the more questions i had.I do not have any miles on these STI Black Diamond XTR tires ( 27x9x12 & 27x11x12) yet but they look good and i wanted to give everyone a idea on the sizing/weights.I had Bighorn 2.0 ( 26x9x12 & 26x11x12) with 500 miles on them and plugs in the sidewall. The tread depth on all 4 bighorns were 5/8".The tread depth on the STI are 1" not the 1 1/8" as stated. All 8 tires had 10 PSI in them for these measurements. The rear tires are the excat same diameter even with the tread depth difference. The front STI is 1/4" taller on total diameter. Also both of rear wheels weighed 39 lbs.The front STI was 36lbs and the 2.0 30lbs. The 2.0's with a steel wheels and the STI with a aftermarket aluminum. I guess this means these 27" STI's are actaually smaller than the 26" 2.0's not counting tread depth? Glad i went with 27's. Hope this helps someone.Read All Reviews

These tires are amazing. I originally had them on a 2015 Ace 570 and now have them on my 2015 Scrambler XP1000 and these tires chew through everything. I tossed the Scrambler full-bore into a mud hole on a logging road up to the bottom of the seat and the tires had no problem pulling me out coupled with the Scrambler's power and drivetrain. If you're looking for a tire that doesn't rumble due to super-aggressive tread but is just as good as other mud-bogging tires, these are the best compromise.Read All Reviews

What I received was a tire labeled, AT 22x11x9 6 Ply. upon speaking with several call takers and sending their tech guys photos. I was told that Douglas just miss labeled the tires. HUH! These tires have been out since 2012. I ride the High Sierras, Bishop to Death valley( Highest and Lowest points in the lower 48) I state that do to the different terrain that I ride usually at high speed and I thought I had found the tire of my dreams. a RUN FLAT! Makes me wonder if these are seconds which they should be if miss labeled. Rocky Mtn. told there should be a white stamp on the side of the tire stating 12ply rated, No such stamp was located on either tire?? It should be noted that I went thru the tire builder program and had these tires mounted on Douglas 190 wheels, Several calls to Douglas have gone unanswered ? Althuogh Rocky stated they called Douglas and were told the tires were just miss labeled I m not so sure, but you can bet when I m done with these tires I will be cutting them in half to find out myself. Let me state clearly the only mistake Rocky made was (NOT) noticing the 6 ply AT, all terrain rating and calling me when the tire was mounted. It should be noted that nobody has rated these tires yet???, As stated in there product listing info the tire has been out since 2012 .Rocky Mtn is still the best place to shop for just about anything a rider might need and I will continue in the future, just disappointed in Douglas for not sending the right labeled tire to Rocky Mtn ps; Still trying to call Douglas.I have not sent these mounted tires back do to the hassle and time it would take to replace them as I plan on riding this weekend and if they are 6ply then that's what I would be getting anyway.Read All Reviews

First ride 30x10x14 Roctane did very well at Royal Blue TN . We had a lot of muddy conditions, and plenty of rocks and tree roots. Was in 2 wheel drive most of the time, very impressed with the tires, was running 8 psi in the rear and 6 psi in the front.Read All Reviews
