225 tyres onto 215 wrx rims
Hi everyone,
My current tyres are 215 45 17's on standard 17" rims on a hawkeye. The fronts are unusual Chinese with almost no grip in the wet and interesting sudden understeer in the dry. The rears are Potenza RE 050's with only 3-4mm left.
My question is can I put 225 tyres onto these rims, or do I need to stick to 215's. I basically I want more grip, but my wife will probably not let me buy new wheels. I know I don't want to go to 18's as more than half my driving is in London and I spend enough with my chiropractor as it is.
In an ideal world I would like some 225 17" STi gold wheels (pre 05 with a PCD of 100), but we live in an imperfect world.

An extra 10mm wider tyre won't necessarily give you more grip. Wider tyres don't give you a larger contact patch, only weight on the tyre and pressure in it change the size of the contact patch. Wider/thinner tyres only change the shape of it and how much the sidewall deforms.
Although you can then get RE070s in 225/45/17 which are one of the best tyres I've had on a car.

yes mate
ive got Vredestein Ultrac Sessanta on my wrx with the standard rims and can report no issues at all.
i didnt do it for the extra grip.its just that i couldnt get the Vredestein tyres in the correct size.
i emailed Vredestein uk to check the 225 was ok it fit to the 7j rim and they confirmed it was.
very happy

I have done this too. I have the Asymmetrics on mine and have had no issues at all apart from the fitter moaning about getting em on the rims! LOL
Well funny.

As they came on a set wrx rims, tyres only done around 1k miles, and only paid £100 for them! Will probably end up getting the tyres swapped onto my 2nd set of STi rims or used on a trackday. Impreza is generally not used much in the winter anyway as use the wifes Forester XT (which has all terrain tyres that have been great in the snow!)
