What size tyres would I need to buy to achive a good stretch on some 8.5 j 17s and some 17 7.5 j wheels?

195/40/17 on the 8.5 and 185/35 or 195/40 on the 7.5. .

Thats what i run on mine. . I have 185/35 on the front and theres not much side wall for protection if you drop it in a pothole. . So you have to keep your eyes peeled.

Cheers mate

A 20mm spacer would give you et15. . :-)

Cheers matey and what about front 10/15 mm and have you had to have your rear aches rolled?

Your fronts gonna be 7.5j et35?. . .so a 10mm spacer would give you et25 which would look good..

No i aint had my arches rolled all the body of mine is standard,but on that pic,the arch is sat on the tire near the back door haha. . .coz mines on airbags.

Front wheel. . .
