Fair enough if your 17 i know how hard it can be to insure something decent at that age!
I have proxies on my cab and there great...(205/40/17 mind) IIRC they are about £48 each for RS turbo rims which is a bargain.
The thing is do you want to spend that much on tyres

you may be better getting yourself a set of RST rims with good rubber all round.. there only gonna cost you arround £120
