Tyres sizes

[Mkgolfnutters]

Hi I am hoping for a little help I changed all 4 tyres on my camper for what I thought was the same size.I replaced like for like 275/40/20 I had on them previously some unbranded tyres thought I would treat her some branded tyres so changed all 4 at the same time I had fitted uniroyal rain sport 5 same size. The van is on Bilstein b14s have had then on the van when we got it. Now every time I hit a pot holes or speed bumps it sounds like the tyres are hitting the wing or something. Very difficult to where exactly as I am driving. Has anyone ever experienced this before I can’t go back to the garage that fitted then as I bought them on line so not there fault. The tyres do look more bulbous than the other tyres any help would be grateful appreciated

Not all tyres are the same shape, even though they are nominally the same size. It sounds like the new tyres are taller/wider than the previous budget ones.
Have a look under the wheel arch liners to see where the rubbing is happening. You may need to increase the ride height. I can’t remember if B14s are adjustable.

Thanks for the reply I think I will have to raise the ride height on the van yes the b14s are adjustable just trying no to do it
