On behalf of a customer, I have a set of 17" GT1's, (Gold) they have Avon tyres in them with some life left but no loads.

slight chipping of paint on 1, others OK.
Tyres are (incorrect size), 235 40 17, but they would last out a full track day at which point new ones could be installed.

I've tried them on my own car and there is only a very slight rubbing of the tyre at the front on the plastic inner guard and only when on full lock.

Offers at/around £500.00.

Bargain.
