Question Would 255/40/17s on 17x8 wheels fit a 2008 WRX without any modifications?

What's the widest wheels/tires that will fit a 2008 WRX without any modifications? Would a 17x8 wheel w/ 255/40/17 tires fit a 5-door WRX without any rubbing, and no modifications (no fender rolling or suspension changes).

As a first place to do a "reality check" "will these fit" type of search, I'd recommend going to www.tirerack.com and using their car search feature for wheels. That will tell you what the widest wheel and tire combo should fit, pretty much guaranteed without rubbing.

They do list Einkei RP03 in 17X8 48mm offset with 205/50 tires...

The wider you go on tires, the more risk of rubbing, and the more road-swale and grooved pavement pull you'll typically have. Why would you want to go with 255 width?

IMO, if you want a wider tire, you'd be better off going with something like a 225/45R17 which only has a .4% diameter difference. (http://www.1010tires.com/TireSizeCalculator.asp)

http://www.discounttiredirect.com/di...ARU&vid=009419 lists alternate "plus zero" sizes up to 235/45R17

I've seen a few sets of 17x8s they had that I thought were nice. Just wondering if the 255/40/17 size would clear the wheel wells and suspension.

Using the miata.net tire calculator (http://www.miata.net/garage/tirecalc.html), it seems that the size is very close to stock (obviously it's wider). But at 60 mph, the difference would be 0.1 mph.

as far as i know, 235 is as wide as you can go without rolling fenders or running really aggressive camber. 235 fits perfectly on a 8" wide rim anyway. you also want to check the offset... its the key to wheel fitment.

Cool thanks. Didn't think 16s would clear the brakes though.

No problems there, they are 2002-2005 WRX size - so 16's are easy.

Nice, because not being able to do 16s in the Winter on my LGT was a royal pain in my ass.

Yeah, I pimped the 16" steelies this past winter.

I am sure 255 is not hard.

without any suspension changes the 08 is a wallowing pig and putting any wide wheels and tires on it will be a total waste

Thanks for your insight, but those of us that own them do notice the advantage the tires give.

My 08 was as fast as an 06 wrx in autocross last year.

You do have to be more controlled with your inputs, but it does hold on well.

As soon as you have suspension, the new rear suspension puts you waaaaaay ahead of the older chassis.

again...waste of time

spend the $$$ on better suspension and then deceide on wheels and tires

eating through a set of $$$ tires because the suspension sucks is counterproductive

my stock 02 was a wallowing pig
my stock 06 was a wallowing pig
and the stock 08 i drove was the same wallowing pig

and burning through tires on a wallowing pig isnt one of the things that ive learned in my life to think to be anything but a waste of $$$

^^^^^ true. I went through a set of 300 rated tires in about a year on springs and since I got suspension have gone through about half a set of 200 treadwear tires. I was especially surprised after an autox where the wear was minimal. If I had done that on my old setup, the tires would have been screaming for mercy as I understeered all over the course.
