If there are duplicate posts on this, I apologize. I came across this calculator that lets you compare tire/wheel sizes and it also gives you detailed info to help decide if the combo will fit your vehicle or not. Its one of the more detailed ones I have found. It allows you to adjust offsets, etc and gives you a graphic display of how the offset, rim size, sidewall height, etc effects the tire measurements. Pretty cool imo.

This is a really good calculator tkt...as an alternative, here's the one I used (every bit as detailed) when making the decision on my wheels/tires combo!

We added a tire calc over at the DOC too that includes Gen1, Gen2s & Gen3s. If there is anything that needs added, please let me know.
