I am due for some new tires, of course as you all know stock size is P225/70R15. I was wanting a little bit bigger tire and was wonderin how big yall think I could go without rubbin. I have a '05 Ranger ext. cab 2wd. Do u think 255's would be too big or should I try to get 240s or 245s? Thanks for the in put in adavance.
