Wheel/Tire Size
I am sure this has been asked a million times before. Sorry. Have 89 350 Formula with stock rear end and suspension. How big of rear wheel and tire combination can you safely use? Thanks

I am putting 18" with 245/40 on my 89 formula 350. JNC026. I am in the middle of looking for someone who supplies the adapter/spacers
