Swapping front and rear tyres

[LeeBrenton]

Hi all,

A few weeks ago I had my wheels balanced to get rid of a vibration at around 60mph. In the process the garage swapped the front and rear wheels as the front tyres were more worn. Today (while checking the tyre size to get a full size spare sorted) I noticed that my tyres aren't all the same size as I thought they were, but are the recommended 215/65 and 195/70. Having had the wheels swapped, the slimmer tyres are now on the rear, and wider ones on the front. I don't think it feels any different to drive, but from your collective experience, do you know if this could cause a problem?

Thanks.

Yes it could, and your insurance will be invalid.

The wider tyres are to take the higher load on the back.

I'd have the garage swap them back ASAP.
