Biggest tire I can fit on a 15in Wheel
 

Hey, so my truck is lowered 4in. I have 14in right now and wanna convert over to 15 but wanna know how wide I can go with the tire and not have rubbing probs when turning. My plan is 225/65r15.

My 1988 B2200 is not lowered, but someone gave me 15" B2600i wheels with decent 235/75R15 tires on them, so when I was due to get new tires, I put those on. At extreme turning, I would get a little rubbing, so I adjusted the two little stop screws on the front end to prevent the wheels from turning to the extreme.

I know this is an old thread but did you notice any power issues/transmission problems with the bigger tires?

I know the speedometer and odometer read like 9% lower than what is actual.
Power is so lacking on these B2200 (Cab Plus more weight) anyway, like 85 hp where my '98 and 2004 Frontiers have 143 hp. But driveability seems about the same, and I've had it on freeway uphills and I'm satisfied. So for me any power or transmission stuff has been negligible or absent.
