This entire thread reminds me exactly why I never scrimp on tyres. They're the only thing keeping you in contact with the road, after all.
452 are sh*t
T1R are sh*t
VUS are good
PS2 are amazing
RE050A are amazing
Depends on how much you want to end up in a ditch, really. That said, even the greatest of tyres or 4WD won't make up for ham-fisted control of a car in bad conditions. If it's that slippy, then just don't drive!
