Warning light popped today, checked pressures, all as should be, mmmm?, went to move car and it even told me which wheel to check- never noticed that before - it then dawned on my earlier this week I stopped a front /rear pair, set the pressures accordingly, today was the first time car had been above 30 mph, must be that the o/side rear tyre was worn more than the n/s which was new very recently (8mm v 6mm) and only at higher speed did the difference bring on the light. Puzzling for a bit but shows the system works, impressed it pinpointed the corner to check though.
