My friend has a 94 stang conv, interested in upgrading rims/tires. He has a set of 18" Konig Monsoon wheels w Pirellis 225/40/18. Will these fit, I believe the rims are universal 5( 5x100 and 5x114.3), so the bolt pattern shouldnt be a problem...how about load capacity of the tires? If he uses these tires what could happen?

thanks!

Nope!!! Needs a 92 Load Index. Those are an 88.
