I’m pretty set on getting BFG KO2s and was wondering if 305/70/16 would be ok off roading? On their site say the min/max recommended wheel width is 8”-9.5” and I’m putting them on a 16x7 wheels. Seen a few members on here running but I’m just curious about airing down and usually go to 16-20psi and a lil worried if I go to low of popping a bead or what not. Any opinions? Thanks in advance

I have Mastercraft MXT’s in 305/70R16 on stock 16x7 wheels on my Frontier. I have no issues going down to 15 front/18 rear on the beach with my truck camper. I do get frame rub at full lock.

Because a picture is worth a thousand words. These are not the same tires. This is when I had 285/75 Duratracs.


This is with the 305/70’s. Ill try to get a picture from the front and of where the tire rubs on the frame.

Better late than never.

285/75 Duratracs on my X. 305/70 MXT’s on my Frontier.


I love how that looks. How many miles you got on them. Some people were say I’d get uneven wear cuz of the wide tire and narrow rim in the long run. Btw what tires do you have on the xterra?

I don’t think the section width makes a difference. I have 265/75’s in the shed that wear the same as the 285/75’s. The outside of the fronts always wear faster than the rest. Even with the lower cam bolts and SPC upper control arms I don’t think there is a way to prevent the front wheels from going like this \ / in a turn.

I can hear the MXT’s are getting louder. I picked up some OME struts and coils. Once I have them assembled I’ll put them on the Frontier. Since the front wheels will already be off I’ll rotate them. It will be my first rotation on them, so I really don’t have a grasp on how they’re wearing.

At first I was running the 305’s at 40psi. I carry a lot of tools. It had a great road feel, but there was 3/4” of tread on each side not being used. After experimenting, it seems like 32psi front/rear is the sweet spot for me according to the chalk test. It does feel a little less ‘grounded’ at the lower psi. If you’re generally unloaded, maybe 32 front, 30 (or less) in the rear would work better. With the camper in I run 42 front 50 rear. On the beach with the camper I’m at 12 front 15 rear. You can probably tell I have exhaustively tested tire pressure variations.

Thanks for the input. I really want to run 305/70. Not to worried on the tire wear in the longer run but main just the off roading I’m concerned if I air down to low of popping a bead. I don’t to any hardcore wheelin or rock crawling at all but I do get carried away some times at the sand dunes and always catch myself making a sharp turn and seems popping a bead that way is somewhat common in that form. Btw what’s your mpg’s with the 305s? I plan on getting AT tires. I know you have MTs but but I just wants a grasp of what they might be
