The recent snap of damp (!) weather has highlighted the shittitude of my rear tyres, which are made by soimeone called Triangle. They were on the wheels when I got them, good tread depth, good condition. It is now that I discover that they are made from some sort of Granite or Flint, and in any sort of grease give my car some hilarious tail-out, shopping-trolley handling characteristics. So, if you want to teach yourself how to deal with lift-off-oversteer at any speed in excess of 20mph, get some of these babies.
