what does fully collapsed mean? Also what is the offset? I am not very savvy when it comes to tires and these terms are something I'm not familiar with in regards to tires and rims. When I put the new rim on it had no tire on it. The junkyard i found them at was "you pull it" and I didn't want to pay for the old, bad tires that were on them so I had to remove them myself with their manual tire machine, which was a total pain in the ass. If LT225's would work I would rather go that route. I was just thinking the 245's would be better since that was what was already on the rims I found. So basically I would have to put them on with a tire on them and turn my wheels fully to see if they are scraping on anything? This is all very confusing to me.
