Will a 15" steel wheel fit on a tC?
I went to Les Schwab to price out some snow tires and wheels for my GF. They said tC's only come with 17 in. wheels so 15 in. wheels might not clear.
And if a 15" does fit, does anyone know the offset? Is it a 4x100?
Thanks.

15's ???? why ? what are you trying to achieve ?
Yes as said above its 5x100 and get the right offset if you are going that size . Do some more research also how this combo will affect the calibration of your speedometer.

And don't be surprised if your MPG increase, and your acceleration increases as well (radius supercedes weight in rotational inertia: meaning that reducing the wheel size produces more power gains than reducing weight, assuming you keep width constant, for traction).
getting 4 steelies and snow tires can be pricy. Also what kind of winter tires are you getting? I hope you are not getting snow tires. Get performance winter tires!
If I were you I would check out www.craigslist.org and find people in your area whos selling their winter tires. Youll be suprised. Also tell me how much you are going to spend.

You may also want to check out www.tirerack.com They have neat little program that shows/ helps you choose winter wheels and tires. Go to their site and click winter.

Rotational inertia is a function of mass and the SQUARE of radius (or was it diamter, but basically the same thing, sorta). What does that mean? Keeping weight constant, reducing the wheel size has an exponential effect on reducing inertia, rather than the linear effect of weight alone. Therefore, going with a smaller, heavier wheel often times outperforms a larger, lighter one. However, the ideal setup is a light weight, small diameter wheel.
My main point is that the size decrease alone is far more beneficial than the weight savings (unless of course the % weight decrease is more substantial by a great degree, which is rare).
Don't forget that increased MPG and acceleration aren't the only benefits. . . your braking power is considerably increased, and if you are a skilled driver, all track times will decrease (considering your tires and wheel width is up to par). But the original poster is only looking for winter wheels, so all this is moot anyway. And small rims are ugly, of course. Hahaha!

I did some research and came up with a tire size of 205/65/15 should be the same height as the stockers. The 15 inch steelies should work fine for winter duty on a tC also. Went to tire rack and they only go down to 16's for winter tires. Hope this helps Bro!
