fwiw, I'm having 4 new Avon ZV7 185/55R15 fitted later today at ATS. I chose them for lower price, 'A' rated in wet and low noise. I do low mileage so mpg and life are less important to me btw. The ZV7 is classed as a Performance tyre, so ride comfort is unlikely to be as good as say the more expensive Michelin EnergySaver, recommended by Culzean.
A relative is pleased with the 17" ZV7s recently fitted to her R56 Mini, replacing the harsh riding Dunlop runflats. Only time will tell whether the Avons are any good on both cars.
I did have UniRoyal Rainsport 3 for similar price from Blackcircles on my shopping list but I think they may be noisier than the Avons.
The existing UniRoyal Rallye 550 were great especially in wet (unlike horrible Bridgestones) but one suffered an irreparable puncture. I replaced it with a Continental Premium Contact 2 and feel it is noisier than the UniRoyal on certain surfaces. Last week I noticed a fine crack running entire circumference within two of the three grooves of the Conti - see attached picture. Tyre still had 5-6mm tread but is 7.5 years old on rear axle. I think Continental own UniRoyal so it is disappointing to discover the degradation in the 'premium' brand tyre.
Only reviews I could find on the ZV7 are posted here:
