very helpful site, thanks!

 

That site is very helpful.

I'm going to move this into the Wheel and Tire forum. Others might like to have a look at this.

 

Glad to be of help. I also think this other fav link of mine would be AWESOME if it was in the NOTES section. It really could answer a lot of repeat questions in here and provide a ton of useful info. Anyone looking for final outboard/inboard #'s, etc just have to plug in what they're considering for replacement wheels/tires:
