I recently replaced the tyres on my 'van. The new ones are directional and have an arrow on them showing the direction of rotation. Despite this, the tyre fitter put one on the wrong way round. I didn't notice until I got the 'van home. My question is - does this matter on a caravan? It's a bit of a drag having to take the wheel off to get it changed but do I need to? Also, the wheels were balanced (no charge) but is this necessary?
