On a car a wheel locates & centralizes on the center hole in the wheel & the bolts/studs just actually hold it on. some after market wheels use a plastic ring in the back of the wheel to get to a very precise fit. I've just fitted 3 new tyres on my eriba because there 6 years old, the wheels are original and immaculate but there not a tight fit on the hub and have to locate on the bolts. I'm thinking of emailing Hymer, has anyone else come across this before. i should add i'v had 40 + years in my own tyre business.

First time i've tried attaching pics (my wheels and hubs) hope it works ok. My eriba is a 320 2015. This is regarding alloy wheels fitting on hubs, they are pretty mint and i would say there original with being a GT

The wheels look better when I put the center caps back in. Just fitted 3 185/70r13 Vredestein all season tyres, polished wheels both sides & waxoil round center of hub & back of wheel to try & stop the dissimilar metal reaction. There reasonably mint & I want to keep them like that.
