Tire Wheel Combo

the ever-present question looms: I'm planning on running Mamba 17" x 8 wheels with BFG ATs either 285 75 R17s or 305s. I'm wondering opinions on the tires. Do you think the 285s will be too tall and narrow? Would the 305s wear to quickly (bow in the middle) on the 8" wheels? I think the 285s and 305s are the same height, just different width? This is an 85% road vehicle.

Thanks!

the 285s are going to be 11.2 inches wide and 33.8 tall the 305s if they are 75/17s will 12 inches wide and 35 inches tall according to a calc.

The BFG A/T's are 285/70/17's. And they don't make a 305 A/T in 17". Sorry!
Can see sizes HERE

But 285's and 305's will fit on 8" wheels and are about the same height!

not if you run the right air pressure.

Do the chaulk test!
Draw a line from side to side, across the tread. Drive 100 yds in a straight line and check the line. If chaulk still on the edges.... too much air.
