I'm running 17x10.5 inches at the rear with leaf springs, 315/35 tyres and have heaps of room inside and out. My diff is a bit narrower than std because American Racing bought out Coddington and effed up my order even after I confirmed measurements 4 times. After grenading my original diff at Heathcote a bit over 3 years ago I went 35 spline and full floater which in this state [SA] means I can get my car engineered with rims wider than 10 inch. I will be putting 335/35/17 tyres on my car when it gets back on the road next year and don't envisage having any clearance issues.

Thanks for the Info mate... what brand of tyres are you running? I was thinking that I would run 315's too & I'd be interested in knowing what you run & if you're happy with them... thanks
