I have a 2002 Dakota which was originally equipped with p215/70R15 tires. Someone gave me a set of p235/70r15 tires will these tires work on my rims and not cause major problems with handling or brakes?

oops original was p215/75r15

That size is still pretty small, it will work fine.

Kenneth,
I am running 255 70r 15's on my 98 truck and they are fine.

Thank You for responding! I just wanted to be sure.
