Toytec Boss will be in this Tuesday. New LR UCAs too. I need help deciding on tire size. I plan on running 3' on front and rear.
275 70 17s or 285 70 17??
I also thought about 255 80 17 Cooper ST Max.
Any pictures or just your opinion would be appreciated :usa2:
I am running 275/70/17 BF AT KO2's I am also running a 3in lift.

K02's are a great looking/performing tire. However, I'd still recommend the Duratrac in this size. Much smoother ride than E or D load range, lighter weight, and don't have to trim fenders. I made the switch from 33's to 32's yesterday, and the difference is staggering.
Do you have a lift? Wondering how it looks. A little smaller size than I was wanting to run
I've always been a BFG guy, but I just put 255/85/16 ST Maxx's on and I like them so far. But I will tell you, they look much smaller on my 4R than the 285/75/16s I replaced. I'm getting used to it but more importantly they perform well off road. They will be a little bit louder than the BFGs though. But they aren't too loud.
Power will suffer with 285's. Gas mileage will drop too but not that badly. I still get 17-18 mpg combined with my heavy, aggressive tread 285's and lots of other additional weight.Can you tell much of a difference in driveability? Gas mileage? Do you lose much power with the 285s?
