Size does matter... :-)
Get something like 245's all around.
The tire brand is up to you. I presonally drive so few miles on the street (and too cheap for a second set) that I drive around
on my 275-40-17 g-Force R1's. Get a lot of looks at work when they tell me my brand new tires are bald already... :-)
Without a long debate on what is THE best tire, go to
