Does anyone know what modern truck wheels will fit my chevy coe truck I want to lower the truck down, I think they are 10 stud 7 1/4 bolt circle?
I'm ***uming that you want to stay close to original with your truck, might be easier to update axles than find modern matching wheels. The only pick-up sized wheels with 10 studs that I can think of is Chev/GMC 3500HDs and I don't know the bolt circle on those. Are you sure about the 10 stud pattern, most were 5, 6, or 8 depending on weight rating.
Going along with Steve's idea, the 19.5 inch truck wheels as found on F-450 and F-550 are 10-hole, no idea what BP. Another route could be to use adapters to run easy to find 8-lug dually wheels, those are 16 inch.
I have 2 of the 8 lug (16"?) from a 53 gmc. We could work out something cheap if that's a route you want to go
Yes, there are 10 lug 19.5 G.M. wheels but they are not real common. I think they were on motor homes, ambulances, and such. Watch Ebay and scour junkyards. They are lower profile and a more common highway tubeless tire.
