A couple questions for Baja Boss owners..

  • Anyone have experience with the Baja Boss ATs and Nitto Ridge Grapplers? How do they compare?
    • I really like that Nittos run more true to size and that's a big consideration with upgrading a bit from stock KO2s to 35s I'm looking for as much clearance as possible while avoiding 37s/re-gearing territory. The Nittos are also quite heavy, which has me more and more interested in the Mickey Thompsons.

  • Anyone have experience with both the new Baja Boss ATs and the recent MTs? Any preference between the two?
    • The 35" MTs appear taller and 3lbs lighter than the ATs, and that's really appealing! But assumed at cost of more road noise, less wet pavement and snow performance.

  • Lastly, anyone know the actual diameter (with daily driving psi) of the 35" Baja Boss MTs?
    • For example, the 35" ATs are listed at 34.5", but lots of folks say they barely hit 34" with low to mid 30s psi. The MTs are listed at 34.8 (at max psi).


Thank you!

I have just posed my results. 4 out of 5 tires were 14+ ounces to balance. I went with balancing beads. 37x12.5x17 on new Fuel Rims.

I have been running the Baja Boss AT in 35 “D” load range for several months now. Compared to both 33” and 35” KO2s they are superior in every aspect except noise level. Theare slightly louder.

Unless you live in or near heavy thick mud and off road in it often there in no need to look any further then the AT Boss. It is marketed as an AT but in reality it a hybrid AT/MT and slightly bias toward the MT side of things.

Size wise ~1/4” in overall listed diameter between brands is meaningless. It is the measurement under load height on the vehicle that matters. Build construction of the side wall will cause the tires to flex differently from brand to brand and overall the difference under the axles is at best within 1/16-1/8” at similar PSI setting. Also rim width will play its part in overall height difference. So just because a given brand lists taller numbers does not guarantee it will be taller. If you want a true 35” tire under vehicle load then you need to be looking at 37” tires.

Both the Boss AT and MT are heavier then most competitors BUT because of this they are hands down one of the toughest built tires you can buy in 35s. I have tried all the top name quality brand offerings over the last 30 years and can say in my experience MickeyThompson (Owned by Cooper) makes the best tires for true off roaders that need strong tires yet still provide for decent general all around day to day use. The new Boss AT goes well above this.

I was really wanting to try a set of the Baja Boss M/T's, but just couldn't wait the minimum 3 month backlog. I'm definitely jumping on a set of them for next time.

Thanks for the feedback on the ATs! They look great!

Regarding weight.. according to the Mickey Thompson site, I think the 35 MTs are ~3lbs less than the ATs (72 vs 69 - and that's impressively light for a 35 mud terrain!)

The reason is less rubber in the tread do to wider spaced tread blocks on the MT tire. Otherwise the “carcasses” are the same in the AT and MT.

ahhh gotcha, makes sense especially considering how aggressive the ATs are

I was looking at the MTs on Discount Tire's website this morning and it says the 35x12.50/17 tires are discontinued?

The old MTs are discontinued not the new ones. Their site is in error. But there is also a backlog on production so they may not be available in stock for 2-3 months. My AT Boss were in the same situation. They were on order for almost three months through Discount/American Tires.
