I've decided spring is here to stay to I changed the Skoda's wheels back to the Trinity alloys with summer tyres yesterday.
I'm convinced it really does pay to remove the road wheels and have a good check around twice per year; the bolts were so so tight on the driver's side front wheel that I had to use my 4' fence post extension to undo them. If that had happened by the roadside I'd have been stuck.
The recently powder coated original wheels and tyres look really good, particularly after not having to withstand the winter weather. The steel wheels got a good clean with Screwfix degreaser and the pressure washer. I checked the tread depth and found I still have 4.5mm on all 4, so I'll be able to squeeze another winter's use out of the Yokohama tyres, which was an unexpected bonus.
