Been using ATM2 for a year now..my reviews on this tyres are

Pros
1) decent handling on both wet and dry
2) affordable
3) silent <60km/h

Cons
1) real noisy (woo woo sound) >60km/h
2) it gives a really loud sound on certain tarmac especially old ones
3) sidewall abit soft therefore it doesn’t give me much confidence for sharp cornering

Personally it’s geared more towards performance than comfort/silence imho

primacy 4 or cc6

too noisy??? thinking of changing from stock silverstone to atm2..how much did u get per donut?
