I've fited standard tyres on mine now. Falken 452's as recommended on another forum and the handling and ride are soooooo much better. Just bought a compressor and some tyre weld from Halfrauds and awy you go.
I had four punctures in a year with the RFT's one tyre only three weeks after it was fitted, Don't get the tramlining now on poor road surfaces and even the wife who doesn't drive said "What have you done to the car it seems so smooth and quiet now " .
