18x7.5 you push it to the max 245-45 is not recommended but who cares ..... want to be safe ....225/235x45 .... considering what's available in the market that is affordable ....35 and 40 profile is nice too but rides like wagon without suspension. i've done it once and never again.

You can go with 235 in the back. Don't lower the back too much other wise you will rub when going over bumps.

Hi there, i checked the manufacturer label on driver side door which indicates your options. I got 235/40/17 ultra performance tires on 7 rims they recommended sport suspension so I purchased h/r springs(they lowered the rear about 1" & the front about 1.5")

Check the tirerack.com online they have rims/tire recommendations............

B30 models have 8" wide wheels with 235's and B32's have 7.5"/225 front and 8.5"/245 rear.

ya 225 is the most common for 7.5" rims, 235 will be fine(I had that set up too), I wouldnt go 245.

i have 245 on the back with an 8.5" rim, with a fender roll and it rubs on bumper on heavy bumps.

B30 got 7.5 all around, not 8



I also got 245/40/17 on the back, never rubbed
