Hi everyone!

I've been somewhat busy/disorganised lately and have unfortunately missed out on the recent track days. But, before i return, i wanted to get an opinion on tyres for a 17x7.5" rim. I have an 86 GVT6 and was wondering what size tyre would fit on the rims and fit on the car without rubbing on the wheel arches. Currently have 205s, but figured something wider would easily fit. Also what R-spec tyres do people use?

Alex.
