tyres for 17

I'm looking for new tyres for my 17" V70R wheels to put on my standard, ie non-lowered 850 T5 Est. I know this is a tired old subject (please excuse the awful pun!), but when looking at mytyres.net and elsewhere, I notice that 205/45 ZR17 tyres are not that common.

I've heard people say that I could use 215/40 ZR17 for a closer rolling radius to that of the standard 205/50 ZR16, but the ride would be hard.

Someone once told me that for a non-lowered 850 T5, 215/45 ZR17 tyres will not scrub on the front or back wheels, but they will scrub on the lowered cars like the 850R

Can anyone confirm this?

thanks

which tyres are the optimum size? It seems that 205/45 ZR17 tyres are expensive compared to 215/45 ZR17 tyres

From what I've seen in the past most people seem to find they scrub. Good fun isn't it when they make a car with non standard tyres. My old MR2 used to have 205/45 14 tyres on it. When I rang for prices from most places and gave them the size they told me what car I was driving (thats how few cars use that size!) and gave me prices of over 100 quid per boot for cheap z rated rubber.
