Hey guys just sitting here trying to soak up all the information available in this awesome site and decided to pick your brains.I have a1991 2wd scab whose original tire size is p235/75/15. Question is what brand and model where on the truck when new?Thanks P.S. it just has generals on it now

 

Not 100% sure, But all of my ford trucks from the 1990's and up until the big problem all had firestone as original equipment. Start with checking those first.

 

Thanks for the info ikinda thought they might have been firestones ,but was not sure.This is my first F150 i have always had a mustang or ranchero.Anyway thanks again for your response. CKM
