Fronts are 245/60 x 15 on stock 15 x 7 Buick Ralleys Rears are 295/50 x 15 on widened 15 x 8 Ralleys Both sizes are about the same diameter (26 1/2) which I like. FRONT REAR
I'm about to convert my bench to buckets with console as well. I have all the parts including the buckets, console, floor brackets, and shifter. I know Buick didn't offer buckets with the Sandlewood interior so I had Legendary custom make me the front bucket seat material in Sandlewood. I thought since my car isn't numbers matching I'd make myself a One-of-None. Just had to have buckets to finish it off inside.
