Beware of wheel trims
I have now taken all of the wheel trims of my motorhome. The vehicle had a full service (including full brake check) at my local garage (well trusted mechanic) before we set off for Spain last winter. We had a full set of trims.
5km into Spain we heard a bang and thought we had a rear wheel puncture. Yes, we had a flat on the inner wheel, but the vehicle lurched over when we stopped and settled on the two loose rear wheels. The outer wheel had managed to move out against the wheel trim and rotated slightly which then cut the valve stem of the inner wheel. The trim them gave out and snapped its mounting on the stub axel. We had no wheel nut on the rear wheel. We had been shedding them unknown to us as we travelled down through France.
We had looked at the wheels regularly at each stop but the trim did not allow us to see the wheel nuts. This cost us two rims as they had been damaged in the process of coming loose.
Thank god we didn't loose one, (as the skirt retained them both) as it could have killed someone if it had hit them.

I have now decided to repaint the rims with "Steel Wheels" and fit the nut caps that waggons use to show if they have a nut going slack.
