can anyone shed some light on Nitto tires, by giving their opinion on this particular tires. Are these tires an Asian tire/product? Is the PS2 tire a superior tire? Sorry for the numerous questions.
Last I looked, Nitto offered very limited selection of "big" tire sizes. They offer a couple tires that are VERY good....the NT555RII-E comes to mind. These grip about 98% as good as Toyo, Sumo, Kumho & Yoko's race tires but they easily last 3x as long. Actually the slightly harder compound is well-suited for a 2 Ton sedan....perhaps not for a 2700 lb car.
With 7/32 shaved tread, the NT555RIIE "wears" like iron, yet they "go" like most race tires....a #1 pick for Driver's Ed & Open Track Event use. Last I checked, they only came in one size (275/45-17). Vette drivers with 17's love them for dual duty track & street.
Nitto sells lots of drag radials too. You don't want those for a 2 ton saloon if you want to go around corners. Some folks say the drag radials are OK for corners fitted on ponycars, but their sidewalls are probably too soft for a heavy E39 sedan.
