M/T Alcoa wheels are designed by M/T and forged/finished by Alcoa. The M/T wheels are not available in the same sizes by Alcoa. For instance, Alcoa sells a 16x7 Classic wheel but not a 16x8. M/T sells the 16x8 wheel and MANY other sizes not available from Alcoa.
Here's a good one, I purchased a set of 15x10 M/T wheels JUST after they were released for sale in the '80s..... only then they weren't named Classic. Hmmm. Is that anything like being older than dirt?
