The one question that seems to come up on all the various diecast forums time after time is “Where can I find a list of all the different wheels that Mattel uses?” The most common (and suitably the best) answer is the South Texas Diecast Collectors Wheel Guide.

Not only do they provide pictures and abbreviations for all the various wheels produced to date, but they also indicated the years that each wheel was used. Also be sure to check out their Hot Wheel Guides as well. Each current year is always a work in progress, so be sure to check back with them often.

Kudos to the South Texas Diecast crew for providing and maintaining such a great resource!
