Tire Size for 1990 Chevy G30 July 14, 2021, 02:00:40 pm I have checked my tire sizes all round, and they all read the same. (Firestone Transforce HT - 8.75 R16 5LT 115/111R). I am quite certain I am practising the definition of insanity. If you have the same model, or just simply know the facts, please confirm that the tires are the same all sound. Being an artist, and therefore a visual person to the extreme, it just looks like the rear tires are smaller..... aaaaarrrrggghhhh! (You are entitled to call me an idiot).

Re: Tire Size for 1990 Chevy G30 Reply #3 – July 14, 2021, 06:39:39 pm I'll bet they are all 8.75 R 16.5, there was also an 8.00 R 16.5 which is a smaller tire. They are a strange squatty tire and getting harder to come by. I threatened to change out our old Dodge to 16" wheels but sold it before I could make it happen.Jon
