Default NT01 review

Well, this past weekend, my first set of NT01's gave up the ghost. I ended up cording 3 of the 4 of them by Sunday afternoon. Having previously used & loved the RA1's, I was interested to see if NT01's were as close to RA1's as folks have said.

They were, and they weren't.

Obviously, full tread NT01's are not like shaved RA1's until they wear down some tread, but they weren't bad. And they did get a lot better when they wore down. In fact, they might be a tiny bit quicker worn down than shaved RA1's. But they are a lot more sensitive to pressures/temperatures than RA1's, and they seem to also prefer less negative camber, likely due to having stiffer sidewalls. I found via probe pyrometer that they preferred slightly higher cold pressures than the RA1's, but even a pound too much created a tire that went away a lot faster, unlike RA1's.

As for wear, I got approximately 30 very hard heat cycles from my set...so excellent value!

One thing I forgot to add: like RA1's, they work well on damp/drying tracks.

VR, I told you all about NT-01s last year.

What pressures did you end up with hot that worked? There was a thread last year that discussed running these tires at very low pressures.

Tim, were you asking the purveyor of all automotive knowledge, or me?


IIRC we ran ours around 34~36 lbs depending on car (951 & 993) and tire size.

The purveyor of course, but I'll consider your advice as well.

VR a timely post, as I have a set of NT-01's delivered this week. 245/40/18 and 315/30/18. Can you give me an idea as to what your car's wt and and what type of pressures u ran. Also if you don't mind sharing what type of temps were you pulling off of them. Thanks.

I know you did, grandpa...but I just got around to trying them this year!

Frank & Tim, I really didn't pay attention to hot pressures, since I was using a pyrometer. I ended up with cold pressures of 25 front, 23 rear, on a car that with drover + fuel is about 3,100-3,200 pounds.

That's downright portly

Yeah, it is. I blame it on the heater core!

Well, I am 200 pounds, and 14 gallons of fuel is 90-100 pounds, and the car often has a passenger!

VR, do you have any experiance with Toyo R888's to compare to the NT01's?

Limited. Not on my car. That said, my initial perceptions (riding in and driving others' cars) are that they are very similar, with the NT01 perhaps being a bit more consistent after a large number of heat cycles than the 888. OTOH, the 888 appears to be (full tread) the better rain tire of the two.

Frank, I forgot to add that I was seeing (on dry track) around 180 to 185 degrees in the hottest sectors of the tires on a warm 80 degree day.
