Default Widest tire on stock 05 WRX 16" rim

I am not buying new tires right now, but maybe next fall, depending on my money situation. My question is, what is the widest tire I can safely put on the stock 05 WRX 16" rim? It's the stock re92's right now, which are 205. Can I put a 215 on there?

I'm running 215/45-16 Hankook Z-212's. Works great.

I had thought about 225/45, but heard from others that it flexing the sidewalls that much would kill my turn-in feel.

Boy that's an awful short tire (about 1 1/4" shorter than the OE size). Doesn't it look kind of funny?

It's only about a half inch shorter in diameter, but, it does look a little funnier than I had hoped.

The gearing is much better for auto-x, though.

turn in is the Intial "bite" into a corner. With those wider tires, the tire will start the turn noticeably before the rest of the car resulting in a somewhat mushy, understeerish feel in the initial few moments of the turn. I wouldn't be suprised if it makes the car a little funky in the slolam autocrossing.... Id love to hear Vpointvicks stance on that last statement before I write it down as fact....and try it on my car.

You've got it right.

All that flexy sidewall makes it take a while before the car actually starts to move in the direction that the wheels are pointed.

Kind of like the difference between rubber and urethane suspension bushings; less deflection= better response.

All depends on the tire though...


A 225 50 16 RT615 will not feel nearly as bad as a 225 50 16 all-season, or not so stiff summer tire.

215 50's are a nice compromise...but again, its all about what tire you are putting on there, and what you plan to do with it.

the fun part was the back end with the stock setup on it, it did start to swing around w/ trailing throttle at "quicker" speeds.
