Nitto NT05 vs 555R - ZR-1 Net Registry Forums

TFENT · 02-08-2011

I have the 555 on my Z plus several other vehicles in my garage. I love them and live in SoCal. I have not "raced" on them but every time I am in the Z it sees speeds up to 120 and I am VERY aggressive in my driving habits. I have a rule, if u have a weak bladder DO NOT get in the Z with me.

That being said I do have a race car I run the Kumho's on and these are not far off from those tires. They have not broken on me yet on the street and have been very predictable. I would say 5 stars on the fun factor.

OK after I got off my soap box I realized you are talking about the R not the reg 555. Sorry...

TFENT - I have the 555 (not R) in 18s on my 1990 454ss and I have been very happy with them. Although the motor is built and the suspension is upgraded on the truck it still doesn't pull like the Z, and I didn't think that the non R would hold me down enough. Are you able to drop pedal to the floor on a rolling start and not light the rears up?

Correct, I can roll and stomp on it and its nothing but pure acceleration. Almost zero wheelspin. They are pretty sticky tires. The only way I can get my Z to break them lose is to mash it and clutch it and that doesnt last all that long.

I had a set of Yoko's on it before and it would lite them up under 1/2-3/4 throttle...

NT05 will hook, especially when they are warmed up. There are some C6 Z06's out there that have broken their half shafts while running the NT05. Saw those threads over on the other forum. So far mine are fine...hehe. One thing I did do was drive in a down poor right when I first got them and they were ok in the wet. I wouldn't et to confident in the rain, but at 60 on the freeway they were fine. Like anytire though they will get worse as they wear down. Those two big grooves must channel alot of water though.

I didn't even know there was a 555(R). I dont think there was when I got my NT05's.
