As you say great fun, my summer tyres are michelins - 19 inch, not sure what make was being fitted to 43 in 20 inch wheels when I bought car.
I don't have any choice regarding full lock to get onto my drive, doesn't have to be "full" lock to crab.
Not sure if you are aware but worth knowing with 43, if you press the close button on key fob twice/quickly after locking car you will see the red light on fob come on and then go off. The key is disarmed and cannot be cloned, stops those pesky thieves stealing your car. Apologies if you were aware but some owners may not know.
