Winter tire question
 

Right now my rear tires are 255/40R17

Trying to find a true winter tire in that size seems impossible.

So I was looking at going with 245/45R17

I'm not sure what my rear wheel width size is, but would you see this as an issue?

Thanks!

OK, got this info off my rear wheel. It says 9Jx17H2. So I am assuming the wheel width is 9"?

and this tire calculator says 245 would work fine on a 9" wheel.

I've been running 235/50x17 Pilot Alpins on the rear of my 03 Boxster for quite a few winters now. Narrower is better for snow tires, as I see it, and these are nearly an inch narrower than the stock 255s.

I've had 245s on my 9' width wheels. No problem.

Order new rims with the tires. Problem solved.

245 is too wide for winters, manual recommends 225.

There is no problem to solve now. These wheels will be my winter set, no need to order new wheels.

I don't think the 245's on the rear will be an issue for me, the front will be 225's, plus look at those tires I'm going to buy.

Got these tires installed on the Boxster this morning. It's supposed to snow here tomorrow, so I get to see how well they work. :)
