Difference between PP2 and AD07..
PP2 is a good tire...but due to its roughness...I didn't like it...roughness feeling is totally different from noisy or bumpy...I can handle noise or bump...but roughness just creeps into you. PP2 is also not a sport tire...its slow to response, more of a grandpa tires to me. Looks also is too conservative if you are the 'fashionable' guy. Dry cornering it is also limited but lucky controllable. Still better than the average NCT5 tires. Wets are great...can't beat a GYF1 ...but close to it..
On the other hand..we have the AD07...it bumps same like the PP2, more noisier (roaring), not so easy to maintain as it is soft compound for the contact patch, average wet capability in puddles, but makes up for super fantastic grippy stuff in the dry. No roughness feeling here unlike the PP2.
Both are a different breed of tires, PP2 is more for conservative and overall drives, AD07 for excitement on the edge on the seat (dry only). I would recommend the PP2 to anyone but mark it down due to roughness....or maybe its just for my size.
