    Yes, they'll fit, but I wouldn't recommend it. I wouldn't go wider than a 215 on a 7.5 rim. 205 is even better. At 225, your sidewalls are going to be at a serious angle which is going to screw up your cornering abilities.

    Why do you want to go to 225 width?

    What do you base this on? Have a look at tire size charts from the tire makers themselves. They show minimum and maximum rim widths for a given tire size.

    225/45 will fit nicely on a 17 x 7.5" rim. I ran 225s on a 17 x 7" rim for three autox seasons. 225 is the largest a 7" rim can do.

    wat?

    I have a 225 on my 17x7 rims, it's fine. I've also seen a 235/40/17 on a 17x7.5, that was also fine. Granted there are variations in tire widths between manufacturers, but a 225/45 on a 17x7 isn't a problem.

    BTW, the stock 06 wheels are a 17x7.

    I noticed he didn't post the right size and I was talking about a 7" rim. As 04.SPT.WRX said, a 225 is pushing it on the stock rims. If you want to run a 225 for every day street use, you should step up to a 7.5" rim.

    I did? It is the minimum recommended size - this is not pushing it.

    I ran 225s on a 17" x 7" for nearly four years. Those same 7" rims will now be my winter rims with 225s on them. 225/45/17 comes very close (.4%) to the OEM 205/55/16 diameter. Have a look: Tire size calculator

    Wider is better, but a 7" rim can safely and efficiently support a 225/45/17. Check the specs from the tire makers.

    Tires will make or break the overall feel of a car.

    Including the OEM RE92s I have had four different tires on my WRX since 2004. Each was unique in the way they made the WRX behave. The current Dunlops are hands down the best yet.

    Um, I picked up my car used. It had 17 X 7.5" rims with RE-070 225/45/17 tyres. Used as the OD had 7 miles on it...

    I'm running 225/45/17 just fine on my 17x7 Motegi's on my WRX as a daily driver.

    My '03 Jetta GLI came with 17x7 rims with 225/45/17 tires from the factory.

    It's not impossible. I used to bullseye womp-rats with my T16 and they're no larger than 225/45/17...


    My Pirelli's (225/45/17) fit perfectly flush up-n-down on my stock 17x7 rims.

    Next time I'm going to 235/45/17 on my 17x8 Ozs.

    What is it about your tires that you like? I recall you said you have tried several sets now. I'm in the IMMEDIATE market for new tires, but am only on stock rims currently.

    I'm on my blizzaks still and a tire thats meant to be soft in the winter is SUPER soft in the summer...I need to get off these things before they are ruined.

    I looked at 4 models of dunlops all in 225/45/17
    Dunlop
    Direzza Sport Z1 Star

    Dunlop
    SP Sport Maxx

    Dunlop
    SP Sport Maxx (new ones of the same model apparently)

    Dunlop
    SP Sport Maxx A

    Other than the Direzzas being Extreme summer tires and having a more gummy appearance and tread style...and likely a much faster wear time what is great about these tires?
