Hi, Anybody know which is the original Tire Size for a Blazer 1975 4x4??
Thanks for your help
My 91 Came with 31's. There is a sticker on the drivers side door that told me this. Maybe yours has something to that extent?
There were many different tube and tubeless sizes available. Some small, some pretty big. You could get almost anything you wanted.
Goto Slosh.com . They listed tire sizes differently then, but you should be able to ask any tire shop what an E78-15B is in todays nomenclature.
Separate names with a comma.
