i have a 1997 F150 and i am puting 35's on it. i want black 15" rock crawler rims on it. What size 15" tires will fit my truck?

 

15's won't fit on a 1997, I'm pretty sure. you'll need 16" wheels to clear the brakes on a new body style F-150

go with 16x8 or 16x10 wheels and 315/75R16's, they are close to 35's. you'll also need a small lift to make them fit, I have a 3" body lift on my truck to clear my 315's. check my pics and check it out....

 

I agree. You need at least 16 inch wheels to fit over your brakes and you need at least a 3 inch body lift to clear 35x12.50's (315/75-16's or 315/70-17's). You can use an 8, 9 or 10 inch wide wheel.
