Plus Avons should be good in the wet as they used to make dinghies
Umm, but a dinghy is designed to float on water?

I have ZV7 (might be ZT7?) on the back of the MINI, seem a little better than the Firestones that were moved to the front when I ditched the cheapo Chinese ones that came on the car.
Had Toyo T1R Proxes on the +4 (but they were a slightly smaller diameter than standard tyres - fitted by previous owner) - no problem with them rain or shine.
Happy with the Vredestein TTrac on the 4/4.
