I'm sorry to say but i have found ATS tyres to be one of the weakest that i have tried. I put on a brand new set of the christiani (white'ish rim) tyres and i clipped a timber, it wasn't a bad crash but more of a scrub. When i was inspecting the car after the race i found chunks of foam missing on the edge of the tyre and you could see where the plastic rim was stressed and a bit bent
I have had similar if not worse crashes since then but while running Enneti tyres and the worst i can do is put a mark them. The ATS rims are extremely lite though so i suppose it's a compramise of weight V's durability. The ATS tyres accelerate better i suppose but as i'm not a world class driver i can't really notice any difference in tyres so for me durability is the biggest selling point. Enneti are definately the best tyres i have ever used, nitro-shoes would probably be the next best.
