Hi everyone well im new and i was wondering if anyone could help me with a little question. I am adding some 18" rims to my car and i was wondering if there would be any big difference between a tire size of 225/40/18 and 235/45/18. Like with my ride comfort and things. Plus has anyone heard of essenza tires those are the ones im looking at there on ebay.

225/40/18====8.85 wide by 25.08 ride height...

234/45/18====9.25 wide by 26.32 ride height...

in my experiences...that could make for a DRAMATIC difference in ride quality...

Thanks i was wondering what the affect would be i dont think i want to go with the smaller ones being that the sport car ride comfort is not all that great to begin with

hmm..what is your factory tire size??

the thicker the sidewall=better ride quality, but it also = sidewall movement under cornering...

thinner sidewalls=rougher ride, but better handling/less movement of the rim side to side in the tire...
