I’m coming to you GM guys hoping to get your support in my attempts to get Coker Tire and/or STA to add 8-19.5” bias ply traction tires to their product lines. I sent the attached letter and spread sheet to them last fall on this subject, with no response. I’ve emailed each again today hoping for their replies. As is seen in the spread sheet, all truck manufacturers of the 1950s/1960s offered these optional wheel tire combos. None of the OEM wheels were approved for use with radial tires, and no tires today resemble the old bias tread patterns.
As Grigg and others here know, I am a student of these old wheels and mostly hang out on the Ford and Studebaker sites. But GM owners are equally exposed. So hopefully you agree there is this need and share your views with these companies. Thanks. Stu McMillan
