I am picking up a new set of rims with some almost new tires on them this weekend from a friend of mine. Compared to the stock 215/45/17's on my SVT, what is going to be my MPH difference with the smaller overall diameter tires?

ur speedo will read 5% fast, ur car will sit about .5" lower, but look .5" higher because of the extra space from less sidewall...

Yeah, I know there will be a larger gap in the wheel wells and this size tire is not the size tire I would have purchased but I can't pass up the deal since my Conti's are pretty much dead.

just take it easy and watch out for potholes. 205/40 tires don't provide much protection.

Yeah, I know. And where I am from, they are really bad here. The good thing about the deal is that I am going to have 4 extra rims, just incase I damage one because of potholes and the smaller tires.

Scholar, I've run 17x7 w/205/40/17 and have no issues with wheel damage. I also ran the tires at 38-42 psi. Yeah, Michigan roads suck.
