All 84-87 cars used a 255/50-16 tire regardless of the suspension package. The 88 car had 16" tires and wheels as standard but it was the first year for 17" tires wheels and they were an option.
Goodyear "Gatorbacks" were the only tire that came from the factory for the early cars.

A mechanic friend of mine thinks I have a bad bearing in my differential. I keep telling him my Dana 44 is just fine; its only the Gatorbacks.
