Just put this on my stock height and factory rims and fit great and look so good. It had firestone tranforce and it was suck a bad ride. Now its so smooth and offroadding with great on rocks and mud. On the 2500hd can go alot bigger and next set well be a 35 firm at stock height. But/ read a review about the size being off in diamater and its true. This say 33.7 and fill mount was almost 33, should have got the 34.5(315/70R17) but next time. 500 miles so far.

Love the tires. I know these have not been on the market that long but man I love them. GREAT TIRE FOR ME!!! Has done well in the rain . Haven't has a chance to hit off road or snow yet but will very soon. I had MTs klevers and nittos grabbers and man these are so much more quite. And my steering feels lighter when turning or hard turning.

Awesome tire all together but the size I bought (285/65/18) was supposed to be a 33 inch tire according to CO and it only measures out to 32”. I should have trusted my previous research on this size but I just pulled the trigger on these.

About 500 miles in and really nice tire, look forward to seeing what they can do in the snow. I can hear them going down the road but not like a mud terrain tire. Good rain traction could be better but like I said they only have about 500 miles. Had great service when ordering these through Custom Offsets with one small issue that was resolved effortlessly. Thank you, Luke

Good looking design of tires. Some road noise due to the size of the tire treads. Slight rubbing on the inner wheel well when making tighter turns. Truck sitting on 2 inch leveling struts. 20×10 -18 wheels.

I have had all different types of tires, BFG's, Swampers, Goodyear's, Generals, and most were mediocre at best. The Boss's are everything and more than I expected. Traction in snow, packed snow, rain is far beyond the others I ran. Ride is perfect, but could be because of a 17" rim and a 33" tall tire, but still handles awesome. Noise is almost non existent. All this with a 50'000 mile warranty. I give a 5 star rating, and would purchase again.

The aggressive tread pattern along with the Alloy Ion 146 wheels changed the look of my truck. The ride is smooth although there is slightly more road noise over the stock street tire as one might expect. Over all, great look and great ride.

Tires were exactly as expected. Very aggressive look but quiet on the highway as previous reviews stated. Tires I ordered are 12 ply sidewall for towing and are stiff and a little rougher ride than stock, but I expected that. Overall very pleased with this tire.

I’ve always loved the look of mud terrain tires and their abilities in the loose stuff off-road, but hated their on road performance, especially on wet roads. These new Micky Thompson Baja Boss have it all… The aggressive looks, tear it up in the loose stuff, and have traction for days on wet/icy/snowy roads. Win/win/win Only thing better are these mindless packages Trail Built Off-road put together. Truly a plug n play product with quick response times with any questions along the way. Many thanks for all the new adventures your tire package has opened up for me. Cheers

The tires look great. Just what we wanted. The only issue was we paid to have the tires bead balanced. Upon installing and running our new wheels and tires, our truck shook terribly. We had to pay over $160 to have the tires broke down and rebalanced. There were 12 balance bead bags in each tire. No wonder our truck shook and vibrated so badly. 12 bags in each tire. Come on Custom Offsets, what were you thinking?

I bought the previous model (Baja ATZ P3) of these tires from Custom Offsets in March of 2018. I have over 80k miles on them. One finally failed on my way home from work. The long wear tread from Mickey Thompson is simply outstanding. My Tahoe powers through snow effortlessly while my father's BF Goodrich AT's just spin and spin. I will be replacing my current tires with these.
