Rallye Tyre Size - Borbet A 7.5" & 9" x 16

10 posts in this topic

I've got a standard Rallye lowered on H&R springs.

I've just bought some 7.5x16 fronts and 9x16 rear Borbet A's.

I don't want the stretched look, so what size tyres should I be fitting to ensure it doesnt rub at all

cheers

Will the difference in diameter not ruin the syncro system?

Agree, thought you had to run identical size rims/tires on a Rallye to prevent diff wind-up?

They seem a bit big to me tbh

ok well the rolling radius is as follows:

i'll ask the question over on the syncro forum too.

Do you think 225/40/16's all round would be ok? Would the front's rub?

cheers

I think you would struggle getting a 225/40/16 tyre inside the standard wing of a rallye

225/40/16 is the exact same rolling radius as the standard 15" wheels/tyres.

205/45/16 is 5mm smaller in Diameter, that's less than the difference between a new set of front tyres and worn rears on a standard set-up, surely the syncro system can compensate for that?

Good point, I to am also interested in this.

Can you run a wider rear tyre with a very small rolling radius change over the front?
