I have a 1983 Jayco J 806. I bought new rims/tires. They are a 4-4 bolt pattern just like the ones I am replacing. The bolt holes are tapered, but the center hole is bigger than the trailer hubs. The original wheels were snug on the hubs. The original wheels were attached with tapered wheel bolts (not studs and nuts). Is it ok to run these, or do I need to change wheels or hubs to match the hub and center holes?
Just remember to torque the wheel nuts when you get them on, also check the air pressure before towing too. Other than that you should be good.
