You cant just grind down the tabs on the hub and get them too fit?

Do you have a stock set of wheels for the truck? If so just measure them. But I have a frontier that I just had a set of caddy wheels machined for. I had them took out to 41/4" and my stock frontier wheels fit my space cab so.. Hope that helps

go on youtube and look it up there is a few people that have how to videos on how to do it yourself. i just did this to a set of lexus wheels and worked great

Dude they are supposed to be machined to 4"  any bigger and then they are not hub centric

Im not that worried about them being hub centric. My stockers are the only wheels that I have ever owned that were hub centric and I've never had a problem one out of any of my wheels. But do as you like.
