I've been on Blackcircles.com and they give a price of £141 (each) for Continental Sport Contact 2 fitted - these have a speed rating of Z. What speed rating do I need? As these were the cheapest that came up within the Z rating category. Are these tyres any good or should I be looking at something different? I dont drive excessively hard and 85% of my driving is on motorways so reduced road noise would be nice because at the moment the budget no brand tyres that came on my car are quite loud. Just seen some Toyo Proxes T1-R's for about £94 each - are these rated any good as its a good saving over the Continentals.
