'Are you saying that the runflats are really no big advantage to have??
Which ones will run best in the winter?'
Im in ChicagoLand too. I put Michelin PS2's on and bought a small air
compressor with tire repair kit . They handle really great in the rain
and are a bit quieter than the runflats.'
REPLY: The only advantage i see in runflats are the convenience of
running on them flat till you can find a gas station to fix them. I
find the PS2's quieter, grip better, and are far more suitable for wet
road conditions (rain). Dont know about snow since i never drove the
vette in it .
