Had Conti's when i brought the car. have always had Avons on my other cars so switched to Avon ZV3's when they needed changing. i really rate them highly and they are mid priced too. (also like the look of them) http://www.avon-tyres.co.uk/?page=tyres&method=detail1&tid=3
ive just got some F1's (£50 each from mytyres ) and think there better then contis in the dry and wet, make less noise goin round bends as well
not had any others on the 172 so cant say about the rest, i was goin for pe2's but where £70 and F1's £50
Always stayed with the Conti's, ive found them to be the perfect mix of grip and longevity!!
