What's the minus-one for a 215/45R17? Thinking ahead for a Subie LGT.

For snows, naturally.
And will the rims clear the brake rotors?
Yes, it's OT for an Audi forum. :-)
TIA.

16" wheels won't fit over stock front brakes. I just bought WRX front brakes and wheels as a retrofit to allow for 205/55/16 snows. 16" snows are slightly narrower than stock, are available in a much wider variety of choices, and are much cheaper vs. 17". E-mail me if you want a post mortem after I tackle the retrofit...
The only 17" alternative to the stock 215/45/17 size is a 205/50/17, which is marginally narrower than the stock 215/45/17's, has an even larger rolling circumference than the common 1/2" width upgrade 225/45/17's, and is an uncommon and usually pricey size.
Note that tire width varies somewhat within same-size versions of different models, even within one manufacturer's full line. Also note the rim width used to measure the diameter; the wider the rim width the smaller the tire diameter and vice versa. FYI, the stock RE92A has a 24.6" overall tire diameter.<ul><li><a href="http://www.4lo.com/calc/gearspeedo.htm">Speedometer Calculator (Compare different tire diameters)</a></li></ul>
