Have a pair of GT Radials (Made in USA) directional tyres, 255/40 x 17. Ideal for the rear Commodore (8" wide) mags. More grip, being, 20mm wider than standard tyre.
The tyres are almost identical in circumference as the standard 235/45 x 17 tyres fitted to the Commodores, thus, no need to re-calibrate the speedo.
About 80% tread left in the tyres.
Bought them used and never got to use them. Taking up space in the garage.
Suppose to retail at $395 each.
Sell the pair for $180.
