I would be interested in any ones opinion on a few tyre related questions. A) any one had problem with flat spots on the tyres after the car has been sitting for a while? are some tyres worse for this than others? B) are any of these high performance tyres fitted with a decent bump protection to try and protect the rims from kerbs at all, I have clipped mine twice in the last 2 years and the local powder coating shop know me by name! C) and lastly a random thought, i fitted good year ultragrip snow tyres to my citroen last winter and i noticed when I changed them over when the weather warmed up the difference is huge, the snow tyres at normal temperatures are seriously sticky almost like slicks. Would a full set of snow tyres in the summer give amazing grip (albeit with very short lifespan?) any one tried it?
