New tire sizing question.....

[ekin95]

Looking for any one that could give me a suggestion. Looking at getting new tires for an 04 on Bilsteins on lower perch. Currently running 18x8, 225/35/18 Front and 19 x 10.5, 285/30/19 in the rear. We have 5mm spacers in the rear to just clear the perch on the Bilsteins. The Bridgestone Potenzas are about done and way too harsh of a ride for my liking so I was looking for a softer ride but with great performance. I was suggested to look at Bridgestone RE-11 or the Yokohama AD-08 but they do not make these sizes. Curious if anyone has suggestions on other brands that would fit the bill or maybe a slightly different sizes F/R that would work but not look too terribly different, rub, etc. Thanks in advance guys......

Currently the car looks like this.

The harsh ride is caused by the short sidewalls that result from using 18"/19" wheels. You're already using oversized tires so there's simply no way to get around that. If you want a softer ride, the solution is to get smaller wheels. 17"/18" is a common aftermarket fitment, and lots of folks are using 16"/17" and 17"/17", both of which are available in stock as well as aftermarket wheels. Also, you can get supersticky "extreme performance" tires in NSX-friendly sizes for those smaller wheels, which (as you point out) are not available for the 18"/19" fitment.
