I re-locate my alu-foil covered cardboard from the engine bay (winter) to the sunroof (summer).

It's easy to check - all for the 'cost' of just jacking up each wheel in turn - or getting your local tyre dealer to put your car up in the air for a couple of minutes.

I've made a ritual of cleaning up the brakes when changing winter wheels for summer wheels. It really works wonders!
