I blew a tire yesterday and am tire shopping, my van is 3/4 ton and loaded with tools so I don't want a passenger car tire. Currently has 235/75/15's but came with 225/75/15's, problem is truck tires in these sizes are limited. It would open up alot of tire options if I had 16" wheels. I was thinking of going to pick and pull and buying a set of 16" steel wheels off a newer van. but dont know about backspaceing etc. It is 5 lug. should work right?
