Upsizing tires & closing the width gap
 

Come spring I'll be due for some new summer tires. Fairly certain the S04 will be the best choice for me in terms of price & performance.

I AutoX about 6 times a year, but otherwise see mostly street duty (daily driven). I want to bring the F/R size & width closer to square to promote more neutral handling.

So far here is what I am thinking:
- 275/35 front
- 285/35 rear

I am looking into Eibach sway bars for the spring as well, but would like to know everyone's thoughts on the matter. Thanks in advance.

Look into Bridgestone RE-71R's. Should come in 275/35 and/or 285/35 sizes. Fits just fine on the stock Rays. It's what most Z drivers in the street class are running for autox. Also if you're interested I have a front Eibach sway bar for sale! PM me

The 71's are a little much for daily duty, and the S04 is cheaper/has longer treadlife than the RE11 (unless someone wants to weigh in).

What are the sidewalls like on the S04? If the sidewall on a front 275 would bulge way more than the rear I may go down to 265.

For the autoX-ers, whats a good pressure for this tire?
