I'm looking forward to riding with UTV Offroad Magazine in Moab and seeing these tires in action.

I'm looking forward to riding with UTV Offroad Magazine in Moab and seeing these tires in action.

When are they doing Moab? I'm curious on how the PB's do also...

Moab nov 12-15th. 20-25 utv's are going to be there. Staying at archway inn.

I just got a set for our 2010 Teryx. I think these will do very well for rock crawling. The lugs seem pretty flexible. Can't wait to give them a try.

OK, I got the tires mounted on Douglas Rockstar OMF beadlocks from UTV Crap today. The pictures below now show the Pit Bulls mounted on a rim and aired up next to the other tires.

First off, the mounted Pit Bull tire is both taller and wider than both the Carlisle and the Stock polaris tire/wheel.

Second, they look BAD ASS.


Some of the changes I have noticed. I have more ground clearance than before with the Pit Bulls. Tire weight between the Carlisle and pit bull tires is very close if not similar. My acceleration and top end speed is the same.

Now, what I am really impressed with is how smooth the ride is. Before, the Carlisle's had a smooth ride on the hard ball and I could cruise at 55+ mph no problem. So after switching the tires out I drove it on the hardball and at 55+ mph with the Pit Bull Growlers, it actually felt smoother than the Carlisle's. I figured the aggressive tread pattern would make for a less smooth ride but it isn't so. The tires are very quite and the ride is smooth on the hardball. It's apparent that their being radial tires is an advantage even with an aggressive tread pattern.

My second test was on the gravel roads and sandy/silt trails. I was still able to cruise at 55 mph on the gravel trails. I did notice a tad bit more drift than I was used to but nothing detrimental given I was on a rutted up, uneven gravel trail at 55 mph. The tread pattern is more aggressive than the carlisle's but the kick up and dust the Pit Bulls created wasn't that much more noticeable. They do kick up a little bit more than I am used to but again, it's nothing major.

The Pit Bulls do grip the terrain, when I doubled back to look at the tracks I could see where the tires had clearly gained traction. In the silt/baby powder they did very well and I was surprised to see that the tread design actually kicks the dust/debris coming off of the tire away from the cab at about a 20 degree angle. So while I think it helps to have the S flares, I didn't find any more or less dust/rocks coming into the cab because of the tread pattern. I didn't feel that the tires sunk or dug in the silty areas nor did I feel like I lost steering control inputs when turning hard. I did notice the huge dust cloud I created but unless you were behind me, it wouldn't matter as the dust was minimal in the cab again.

I will take a ride in the rocks and steep softball size scree hills tomorrow and let you know how they perform going over and up rocky terrain.

So far, I am REALLY impressed with how these tires perform, especially on the hardball. They feel like passenger car tires on the hardball and are not "knobby" feeling at all, even at 55+ mph. The added height I gained is also welcome as I didn't have to do anything other than change the tires out to gain lift while still running a 25" tire.


Did I mention how BAD ASS these tires are?

Jacobs ATV magazine has done an extensive review of our Rocker Uber XOR and has run a comparison to a popular tire
http://www.jacobsatvmagazine.com/tmp/pit_bull_tires/pit_bull_tires.html

I thought I'd update more on the tires performance over rocky terrain and trails, to include bushwhacking across open desert and to comment on their durability now that I've logged some more miles on them.

Due to the huge storm that recently passed through Arizona, I've also had an opportunity to ride in some really muddy conditions and standing water. I didn't have a camera handy at the time but I can report that these tires are monsters in the mud and can handle anything you could potentially have to drive through. Expect to see mud fly no matter what speed you drive at as the tires clean themselves out extremely well. The tires hook up and pull hard even in the mud, I was impressed by the amount of speed I was able to keep as I hit what I thought would be that sucking mud that pulls your down deeper and deeper. Plan on getting dirty and hit by flying mud as theses tires attack mud like a starving pitbull attacking a pork chop.

Now on to the rock crawling, rocky trail riding. I'll let the pictures do most of the talking but in short, I drove over everything from your average dirt country road to basketball sized boulders and scree fields on terrain that ranged from flat to 45-50 degree inclines on uneven terrain. In all cases, the tires performed better than I could have expected and I intentionally went looking for terrain that would slow these tires down. Throughout all of this the tires still look new after I washed the dust off of them and the wear is minimal despite the rough rocks and cross country desert driving I subjected them to. I expected to see chunks or cuts out of the tread blocks or sidewalls after a few runs through a volcanic rock scree field but when I inspected them, they showed no damage what so ever. I am convinced that there are very few situations that these tires cannot handle and more importantly, I don't think there is a tire out there that is in the same league that can handle such a variety of terrain as the Pit Bull Growler. Enough gum flapping, here are the pics, enjoy.:)

Do you have exact measurments when mounted. I'd like to try a set on a 2wheel drive Rokon motorcycle. Also do the flex at all when down to 2 or 3 psi?

Exact measurements for what size? What rim width? 25.5" run about 26.25 on a 7" rim. 26.5" run 1" taller

when will the 27.5's be avail?

The 27.5" Growler Uber XOR molds are at the factory and I'm hoping end of March.

Exact measurements for what size? What rim width? 25.5" run about 26.25 on a 7" rim. 26.5" run 1" taller

26.5" is pefect! No mods to make it clear and just enough clearance for some mud or rocks. 25.5X8R12. The rims are a funky hollow aluminum drum. The drum is sealed so they can be filled with gas or water or as I tell folks, I put gas in the front and wiskey in the rear and I can run all week! :p
The drums are odd and come in just under 6" wide. The problem will be at the widest point of the tire on the sidewall. Thats where the chains, yes it has a chain to the front and rear would hit the tires. I have a little wiggle room because I could add spacers ... but not much wiggle.

I developed and sell a mellowed out Yamaha YF200R1 Burris cart racing engine as a drop in replacment for the stock Kohler 6HP. It turns a Rokon into a realiable killer with double the power. If we only had a decient tire that would fit we would be really cooking. So how wide are they? I need the widest point on the sidwall. Do you have a ripped up or blem tire I could test fit? One more.....Whats the weight of the tire?

Thanks and I hope we can make these things fit. A tall 8" tire is what we have been dreaming of forever.

27.4 fronts
32.4 rears

Each tire may vary in weight slightly.

27.4" Is that for the 25.5X8R12? If so I can make that work by easily trimming the factory muffler mounts. I need to know how wide they are at the widest point on the sidewall. The Carlise factory tires are the are 25x8x12 and the measure 7". I can go 8" but any more and I'll have to take a closer look at what needs to be done to make room for the chains. If they fit then put me down for two fronts to 85087.:)

some good info in this thread... thank you.

Those are the weights...not the OD.

I got a set on today. The look knarly but run small. On a narrow 6" rim they are 25 3/8" tall and 7" at their widest point. They ride smooth but may need more air than I'm used too because they are soft. Soft is good for the rocks. I'm sure they would be taller and maybe wider if I bump the air up past 4 psi I started with.

Edit: Luckily I live at the base of a bunch of trails and was not far from home when the front tire peeled off the rim. These things are way soft and I'd run max air in a UTV. They call for 7psi max and I lost a bead at speed with 4 PSI. Thats more than I ever ran in the Carlisle tires I had and I never lost a bead. I reran them at 5psi preety hard and they were OK. The bike only weighs about 200lbs and I'm 185 so it seems odd I lost a bead. I seated them with 30psi and droped them to 4. 5 is too high and they bounce. Rokon factor site recomends 3.5psi. I wonder why one peeled off so easy?

Running low psi #'s without beadlocks is always a gamble if you're going to expect them to perform at higher than crawling speeds. And the, sometimes, tires simply come off the rim.

When I said speed only meant about 25 mph. Thats fast on this bike. The factory recomends 3.5 psi and these peeled off at 4 psi. These tires are soft as hell. I could have mounted them with my mountain bicycle tire irons. I'm going to bump the presure back down to the recomended 3.5psi and see if they hold. They are so soft I can't see much anything but max pressure or double bead locks holding them on. Do you think an inner tube would help? The don't make Stuans for a 12x6 rim. This is a quote from a fellow Rokon owner when I asked:

"

I run the Maxxis Bighorn 25x8x12 radial. I have had them mounted for over a year now, I run 2.5 psi in the rear and 3 psi in the front and have never lost a bead. I have worked them plenty hard in the rocks of W. MD, especially now with the extra speed of the YF200 engine. Mine are mounted on the drum wheels. Not sure why others might be having problems at these low pressures. Just my datapoint.

I don't know what to tell you. I have run mine at 4 psi with Douglas beadlocks in the sand/dirt and then driven home on them on the hard ball at 45 mph without any issues.

UPDATE: With help from the President of Pitbull tires I fiqured out why I lost a bead so easy. Hows that for customer service! :p The rims are slick smooth on the inside and I had a lot of tire mold wax built up from over the years. Not to mention I run less than 4PSI. I cleaned off the bead area of the tire and roughed up the rims. I then used some 3M trim adhesive for good measure. I would have been sick to not be able to run these tires. The Rokon has no suspension except for the tires and these tires make a huge difference. At any kind of speed, 3" rocks used to bump me off course and now I don't even look at rocks smaller than 6". I did remeasure the height after some break in time and with the recomended 7PSI. They are a true 25.5" tall. I spun the crap out of them on rocks and no cuts. Not even small ones. I don't know how they do it and remain so soft but they do. I can grab the knobs and touch them together by hand. Thanks to Pitbull for a great tire!

Pit Bull Tires ROCK!!

26.5" Rocker Uber XORs are available now.

Arizona got rain. No mud ever seemed to pack in the tread. I could blaze thru the slick goose grease mud with full control. We have clay that turns into 5" of super slick snot. Deep rutted mud was pefect for me because I drove right thru without sliding but I'm not really a mud puppy. They absorb bumps and rocks so stuff I'd have to crawl up in first is now wide open in 3rd. I'm running 2.5 psi and all I can say is wow.
