I run 225/40/18 size wheels on my car. My rims weigh 21 lb according to Enkei and I am very tempted by the reduced weight of a wheel like RPF1 for example. Almost 5 lb, IIRC. However, wheels are highly individual and subjective, and I would still want to fill out the wheelarch. I really don't like the tiny wheel look. Having said that, I checked out tire rack for tire weights and used a Michelin Pilot Sport 4S for this comparison. I specced it in 225/40/18 and got 21 lb. Then changed it to 245/45/17 (sufficiently meaty?) and got 24 lb. That would almost negate the weight savings. Are people aware of this? Are these weights provided by tire rack correct? Cause that would take a 5 lb per corner advantage and cut it down to 2 lb...
