I'm in the market for a new set of tyres but do have a budget of around £500 so I won't be spending £900 a set. I've been looking at new mid range tyres or nearly new part worn top range. I have found 4x brand new Kumho KU39 for £555 delivered. The Kumhos have good reviews & people seem to love them. Very good comments, even people saying they are better then top range tyres they have had previously. I have also found some Pirelli P-Zeros, two with 7.8mm, one new & one with 7.5mm total price= £515 delivered. Reviews on these haven't been as good as the Kumhos would you believe with some people saying wet grip isn't that good. From what I've read on the Pirelli website these are their best tyres for supersport & high performance cars. Also found some P-Zero Rossos, two with 7.3mm & two with 7mm total price= £530 delivered. From what I've read on the Pirelli website these are their tyres for mid - high performance cars. Again reviews on these haven't been as good as I expected. I will also be leaving these on all year round so they need to be good in bad weather also inc -temps, snow & ice. I'm expecting the car to do most of the work being Quattro so hopefully tyres won't be as much of a concern as a non 4wd car. Naturally you would go for either of the Pirelli tyres but it is always nice to have brand new tyres delivered with the stickers on so the Kumhos are saying buy me I'm new. I'm also thinking Pirelli should be a better tyre though being top of the range. What are people experiences with any of these tyres on our Quattro 6's?
