RarlyL8 what was the ride difference between the 15" and 18"?
Night and day. The 18's feel like I am driving on rails compared to the 15's. The sidewall hieght of a 345/35-15 is 4.75" while a 315/30-18 is 3.72; that is over an inch difference per side! The overall change in tire diameter was less than an inch. When compared side by side the 345 looks like a truck tire.

I hope the rim width growth thing stops soon as it is getting stupid. I would prefer to put 17s on my car but no one makes the tire sizes I prefer. At 25.7" the 315/35-17 is too tall. We need a 335/30-17.
