Putting modern wheels on a '79
I'm about due for another set of tires and would like to replace my old, possibly original steel wheels and mis-matched hub caps, with aluminum wheels as are put on the new Airstream trailers.
A year or two ago I put a new set of GKN axles on my trailer which use lug nuts as opposed to lug bolts, and I know I need to get the pretty closed end nuts so all will look nice.
Question is, what tire size do the new trailers put on these aluminum wheels? I assume the bolt pattern will match up with my axles but is there anything different regarding wheel well clearance or axle spacing that makes putting the new wheels and OEM tires on a problem?
