I'm going to install a add a leaf and crank the torison bar next weekend. I want 31x10.5 15R tires. I can get them online for a little cheaper I think but i've only have a few sites which are tirerack.com, tiresavings.com and discounttiredirect.com. I don't want to spend over $700 for them and I don't want to hurt my gas mileage. So if anyone knows any sites it would help a lot.
