I have decided to purchase the ASA JS1 15" rims from tirerack. Now to decide on the tire size. Most people here I have read are using 205/50/15. I have also read in the wheel document that we can use 205/55/15 tires for a "smoother" ride. Anyone have any opinions between these two sizes? Do the 55s rub since they are a touch higher? The tires I have chosen are the Firestone Firehawk Indy 500, they come in both sizes. This tire seems to get alot of good reviews, and for 66 bucks a pop not to bad. Thanks.
