I've got the 20" Bridgestones on my LTZ and I'm not a fan of them or their diameter, but I'm not paying to change them. What I notice, though, is that the gas mileage and handling are very sensitive to inflation. I mean 2 or 3 pounds down from the specified 35 psi and the mileage suffers a lot, and they seem to wallow and feel drifty and spongy at just slight under-inflation.
Anybody else have similar observations? How about the smaller diameter tires? I'm betting they're much more forgiving than the 20s with their larger interior volume.
