Tires FEDERAL or NANKANG

I just went from Federal 595 RS-RR (very loud but performed well on street and autocross) to their 595 RS-Pro (waaaaay quiter, I love these tires so far).

I also own a set of these, I can confirm. Fits my BMW very well as they used to make airplane engines, and these sound like a Messerschmidt prop plane.

I myself drive Nankang AS2+ with the dimensions: 235/35 R19.

Apart from the less direct steering and a driving profile that is a little more geared towards comfort, I am very satisfied.

I have a great grip feeling and the rim protection is slightly wider than with the nexen nfera su1.

Look at the NANKANG line. Start at NS2R. I use them on my Exige. But use a softer compound. If you need “more”, the AR1 are THE ones to take. But there is a new Kid on the block. NANKANG CRS. For that amount of monney, you wil hardly find a better tire.

Federal 595 RS RR

Wear earplugs. They're great.

These are the Nankang CRS tires, saw similar wear pattern from the RT660s as well (in fact that kind of just chunked away leaving rings of cords).

We ran them on our champ car endurance race car. They were ok for what they are. Beware they will get greasy after around 10-15 laps at full pace and grip goes immediately. Caused significant understeer at the limit when this happened.

Federal tires are cheap and good. I use Michelin PS4 but on wet paint they're almost useless.

My i3 had nank’s. I destroyed the rears in less that 10k km.

I have a set of Federal RSRR. They only have about 3,000 miles on them. I took them to a track day and there was no feedback on when the tire would lose traction, the car would go from full grip to zero in a snap.
