They're pretty close to the same size as the originals. What pressures are you guys running? Also interested in what '74 B and E bodies tire pressure stickers said from the factory with factory radials. Thanks!

If the car calls for 26 psi,go to 32 with radials. Most Mopars called for 24 psi up front,so go 30 . Just a couple examples that work well with stock original or restored cars.. Cars that had any suspension or chassis mods or larger wheels & lo-pro tires will have to be set differently to work with said mods.. Hope this helps.

Too much pressure will leave a narrow burnt rubber patch in the middle of the tire track, while too low pressure will leave 2 burnt rubber streaks on the outside edges of the tire track(s), but nothing in the middle. This is pretty much trial and error, and can vary a lot depending on tire size AND width of the rim. Scott B. "I'm a self-made man...
