Newbie Tire size question

[AddictionRacing]

Hi All - I'm so new to the Boxster scene that I haven't even picked my car up yet. Thursday is the day. I am an autocrosser and want to put some wider, stickier tires on the car than it currently has and am wondering what the widest tires are that I can fit on the stock 17" rims on a stock 1999 boxster. As I'm sure you're all aware, the stock sizes are 205/50-17 and 255/40-17 but I was thinking 225/45-17 and 275/40-17 Falken Azenis 615s would be better. Does anyone have experience with this or a similar set-up or have a better idea? Would these fat guys even fit on the car without rubbing (without rolling the fenders)? Thanks in advance for your help!

Addiction,

My autocross buddy just put 245/275 setup on his 17" x 8.5" stock wheels.

( I believe he went with Kumho Ecsta V710's )

He is not running spacers and they seem to fit fine :

Hope this helps...

Thanks Nick - That is very helpful. Eventually I'll get a 2nd set of wheels with R-comps, but first I need to unload the old car (Jetta) along with the 5 sets of wheels I've accumulated for it.

I am running 275/35/18 on mine but I am not on stock, I have 18x10.5 on the rear. 275's work but you may need to roll the fender if you decide to drop the car

I think a 275 will be a little sloppy on a 8.5" wheel.

I'm running a 245/275 setup with Kuhmo V710's on 17x8.5" wheels. The 275 is a stretch for the 8.5" rim but I am truly impressed with the difference in handling. OMG does the car stick! I don't use spacers but it is a tight fit in the front. The rear could be spaced out a little but I'm not planning to do this because I'm thoroughly impressed with the handling at this point.
