NT05 tires vs MPSS

[Jinxx]

I have been through 2 sets of the MPSS and both sets seem to get hard and become awful for traction ....Both sets seem to have done this at around the 2 year mark ....and still have plenty of tread left. After researching the NT05 most info either is confused with the NT05R tire or goes directly to that conversation.

I’m assuming that the MPSS are just getting old before I use the thread and then become less grippy so I was thinking the NT05 would be softer and wear down before/if the tread gets hard ...the MPSS are rated 300 treadwear AA traction A temperature ... the NT05 are 200/AA/A if the ratings mean anything from one brand to another.

I’m running 612hp/511tq and I know anything less than a R compound tire will struggle with traction ...any info and experience with different tires will be helpful

The MPSS was replaced by the MP4S with similar specs but supposedly better life. You might want to give that a try.

Also, have you checked your alignment? Make sure toe is in spec

Everything is aligned ...I did add adjustable camber arms to take out some negative camber to square the tires up (305/35/19)....the life of the tire hasn’t been a issue ...seems that they don’t wear and just get hard and lose traction

Also first set was on my 2015 nismo..second set was on my 2017 nismo....both were boosted

camber will affect straight line traction, but doesn't really affect wear

its your toe that you need to check to see if wear is affected

There isn’t any uneven wear

511 lb/ft of torque when exploited is going to turn the tyres.

Wheelspin overheats the tread surface and will eventually make the tyres hard.

This what you are seeing.

Options:
1. Get an adjustment for your throttle pedal (connection between brain and foot) to modify wheelspin frequency
2. Retain driving habits and try AA/200 tyres - I suspect they will wear out in less than 2 years OR they may go harder faster
3. Sell car and purchase bicycle
4. Follow someone else's suggestion

Seriously, you will need a massive wide tyre to provide grip for the torque you have. Put those wider/grippy tyres on the car and other parts of the driveline will start failing.

I have had NT05 on my car and did not like them as they went hard after a year (I cover ~20K klics per year).

Best option I can suggest is Dunlop Direzza Z3 but not sure whether they are common in the US. I've used a couple of sets on my car now.

Wheel spin is at 1/4 throttle ...1..2..3rd gear soooo with them in this condition ...wasn’t so at first ...just looking for other options
Was the only issue with the nt05 was mileage ? ...how did they perform ?

What is happening is that the MPSS are being heat cycled. Everytime you spin the tires. The tires goes through a heat cycle. Enough heat cycles will cause the rubber to get hard and less grppy. This will happen to ANY tire. New MPPS. I can go about 25 minutes on the track before they start losing grip and become greasy. After about 5 trackdays. The same tires will go about 15 minutes before they get greasy. The tread wear of a 200 tire will have more grip but shorter tread wear then a 300 tire. A 300 tread wear thread will have less grip but more tread life then a tire with a 200. Most cases, a 200 tread wear will heat cycle faster then a 300 tread wear tire.

Run an R888r and get the diff upgrade we have suggested to you. They will last about a year. I got 7k on mine and they are a little over half done. Yes, they will heat cycle and take longer to heat up to a level of good grip. Expect about 10k out of the rears. That's it. This is with a 325/30/19 R888r with an 11.5in width rim.

Figured they were getting like that due to heat ...and the reason going to a 200 tire was to at least burn through the tread by the time they got hard ...hate to toss tires away with a lot of tread that’s hard as a rock ...makes me feel like I didn’t get the use of the tire

I’ll prolly hold off to switch the diff out ..at least until I see what I can do with new tires ....as far as the r888r ..wouldn’t they be same type of tire as the nt05r..and mt street as ...and not great in the rain or for a daily driven car?

You don't want to listen do you. You are on your own.

Wow ...so I should just blindly listen to the great word of spooler and if not ..then the great spooler says your on your own ...just wow

Would upgrading the diff improve the situation ..yes it would ..is it causing the issue that I’m having ..maybe not. As other people have stated they have had no issues with theirs for straight line traction and have ran 10 sec passes numerous times on the stock vlsd. So why would I spend 2k on something that may not even need to be replaced .....oh ....cause the great all knowing spooler says to ...

Go play daddy to someone else

VLSD won't help too much with straight line grip. Better tires will. R888R's hook well. I've had success running Kumho V720's. If you're running a wide wheel, they have 355's that were on the Viper ACR. I don't think those will soon on you. They're $358 each.
