I drive a Liberty specifically and it's time for new tires. I have 235's on now but the factory tire size was 225 and I'm trying to determine for the next ones, which size would help give a smoother pavement ride and acceleration. I only use it as a car, so on the road, highway, and downtown's bumpy, pot-hole infested roads.. So, it's not really being used as a "Jeep".. I'm just trying to determine for a more comfortable ride over the roads' bumps and also in acceleration, if tire size would make a difference then which side would offer the most? Thanks alot in advance for your knowledge!
