Got my 295/60 R20 Mickey Thompson Baja Boss on last friday. I said I would post my thoughts once I had them on.
Compared to my same size Nitto RG's, these are .4' taller and just a tad narrower (like .2"). The tread depth new on the MT Baja Boss is significantly deeper. The tread style, including siping, is also significantly better than the Nitto RG's.
Looks wise, I still prefer the Nitto RG's. But almost everything else, the MT Baja Boss are far superior. Traction on all surfaces is way better. Even when new, the Nitto RG's did not have nearly the traction profile that the MT Baja Boss have. Snow/ice performance is light years better with the MT Baja Boss. I actually made it up my steep, winding snow/ice covered (it is that way 8+ months of the year) mountainside drive in 2 wheel drive with the MT Baja Boss. I had to test them out first drive up my driveway last friday after picking my truck up from them being installed. Snow/ice traction is incredible for an AT tire.
As far as ride and road noise, I think the MT Baja Boss feel a bit heavier, which they are by 4 or 5 lbs each over the Nitto RG's. My Nitto RG's were worn down to the bone basically, so they were probably darn near 3/4" shorter at this point than these brand new, .4" taller, MT Baja Boss. So that 3/4" difference in height from what I was running makes a little difference. The tires feel a big heavier on the truck while driving to me, but nothing extreme. Rubbing is about the same - even after trimming I did a long time ago for the 295/60 R20 Nitto RG's, there is still a little rubbing at near full locks.
The sidewalls of the MT Baja Boss don't look as nice, but then again the Nitto RG's are the nicest looking AT tires period in my opinion (and lots of others opinions). They still look nice, but not as nice.
Overall, for my needs living above 6000 feet in the mountains of Montana with 8+ months of true winter weather, I feel the MT Baja Boss will be a ton better for my needs. How they wear and how the traction becomes lessened over time I will have to find out. I have had Nitto RG's many times in the past on different trucks, and getting 30 to 35K out of the is really stretching it. Trying to drive in fairly extreme winter weather living on a steep mountainside with tires that are worn down to not a lot of tread left is not ideal to say the least. I needed to change out my worn out Nitto RG's two months ago, not wait until last week.
I think these are going to be great tires. Much, much better snow/ice traction, deeper tread, much better and more advanced tread profile, much better siping, which will all lead to a much better all around tire for my uses. I will update with any changes in opinion as I use them more.
