I'm currently running 275-30-19 rears on 10 inch wheels. I would've sworn they were 275-35-19's. Anyway, what would I gain/lose running "35" series over "30" series? Should I just leave it alone? I need to order 2 tires this week is the reason I'm asking. I'm running "215's" on the front BTW if it matters. Thanks for any wise input.:smile:
