Storing Nitto Tires In The Winter
« on: February 03, 2017 - 06:49:41 AM »
 I need to find out how you are storing your Nitto tires (NT555R)during the Winter months. I read a few warnings that say the tires should not be in 32 degree weather or cooler.

My garage is not heated and it does get below 32 degrees out there in January and February. I have read where you should jack up the car to get the weight off of the Nittos and drop the air pressure during the Winter months. I have also read where guys take their Nittos indoors during the Winter months too.

How do you store them when you are not driving your car during the Winter?

--------------------------------------------------------------------------------------------------------------------------------------------------------

""FOLLOW THESE INSTRUCTIONS DURING SUB-FREEZING CONDITIONS:
1. Do not operate the car with these tires, as the tires may suddenly fail.
2. Always store these tires indoors at temperatures above 32°F (0°C).
3. Before mounting or dismounting, store these tires for at least 24 hours in a temperature-controlled
environment of 68°F (20°C) or warmer.
4. Remove these tires from the vehicle and deflate to half the normal air pressure during prolonged periods of
non-use or storage.
5. Do not move a car that is in storage with these tires, as the tires may crack.""

-----------------------------------------------------------------------------------------------------------------------
 I found this statement that says do not drive them below 15 degrees, which makes sense since they are a performance tire and not an all season tire. Even 32 degrees makes sense to me but I am more worried about issues with storing them in 32 degree weather.


 ""Cold Weather Consumer Advisory for NT555R, NT555RII and NT01 Tires""

    In February 2010, Nitto Tires issued a consumer advisory regarding proper cold-weather handling of all NT555R, NT555RII and NT01 tires. If these tires are exposed to temperatures under 15 degrees Fahrenehit, they will lose rubber compound flexibility. This can lead to cracking, which can result in a potentially dangerous accident. To minimize damage, Nitto Tires advises that consumers not drive cars with these tires in conditions below 15 degrees Fahrenheit and check tires for signs of cracking.

I have Nitto555, not all that happy with them. If the car sits during the summer for a couple weeks they get flat spots...anyone have a recommendation on an alternative tire?

 Out of curiosity, what psi do you have in them?
------------------------------------------------------------

 I found this info on Flat Spots"
 ""Though flat spots on tires are a normal occurrence for many brands and types of tires, high-performance, high speed rated (H or higher) tires are especially prone to have this problem. High performance tires are engineered to maximize contact with the road surface in order to improve handling at high speeds. Such tires are typically softer and stiffer, with a low profile and larger tread elements.

The very qualities that make tires capable of high performance leave them vulnerable to tire flat spotting. The larger, softer surface of the tire is more likely to absorb heat, cold, moisture, and chemicals from the ground itʼs parked on, especially concrete floors.

Factors that increase the likelihood of a tire flat spot include:

•   Low profile tires with short side-walls and a wide footprint

•   Nylon-reinforced internal constructions

•   Heavy loads

•   Under-inflated tires

•   Fluctuations in temperature

•   Long periods of storage/lack of use""

Scroll down to "Storage".

Yes, flat stoppers will be purchased with my next set of tires, makes the most sense. I run my tires at 32 lbs and someone suggested to pump them up to 40 lbs when sitting...I am looking for an alternative to Nitto 555's though, anyone have a recommendation?

Do you do anything special for storage?

Nope. Don't change the pressure. Sometimes they are in the air. Sometimes they spend the winter holding up the car. My garage is heated though. Keep it above freezing.

My garage is heated at 60, I don't feel the flats spots until above 55....you don't feel any vibration?

The flat spots eventually work themselves out, right?   :clueless:   I've got 555s and my car is on some HF rollers - perhaps it's time to put the car on stands.

Slow speed initial vibration goes away, but not highway speeds...

Nope. Maybe I'm more vibration tolerant? lol
How do you know it is your tires giving you the vibes you feel above 55?

I took them to my friend who is a long time tire shop owner. He rebalanced them as best he could, but said they had flats spots.

The compounds they use to build performance tires have more (plastic) not for sure if that's correct terminology but they are susceptible to cracking do to these performance compounds. They are same recommendation ALL performance tires have, dirt track, autocross, HOOSIER, BFG, FALKEN etc. You should be able to store them in the with just the tires, but no weight or mounting. You sure don't want to be throwing them around in the cold. Hoosier had a problem here in the upper Midwest a few years ago with tires cracking and they said it was due to poor handling practices in cold climates, of course no one knew if HOOSIER heats there storage buildings or not?

Thanks for the detailed reply. What do you think of Flatstoppers plastic tray to park in-on? Reason, I am considering is because I noticed flat spots even after a few weeks of sitting between summer driving...https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjp1pyI2_TRAhXK6YMKHeJbDWgQFgi1ATAA&url=https%3A%2F%2Fraceramps.com%2F&usg=AFQjCNFi34QndK1Ke4rbDZ8_mH8Htvug1g&sig2=c2bAWsQK-OCVND9_5wbsAg
