Air pressure for aftermarket (car) tires.

[Huddleston]

I know I have seen this discussed, but for the life of me, I can't find the message thread. I just installed a Kuhmo rear tire and 2 Federal front tires. The dealer put 19.5 psi in the front tires and 33 psi in the rear tire. Can someone who has installed aftermarket tires tell me what you use? And, can someone point me to the message thread if this has already been discussed? Thanks.

your best bet is email your tire manufactures tell them your application and let them give you a recomendation

Without finding the thread you are looking for, I'd say you're pretty close. I use 27 in my rear tire, but try what you have for awhile, and make slight adjustments, for your own riding style. Good luck.

I have a Kuhmo on the rear. 30 PSI works great.

 

[SpyderAnn01]

Try 28 in the rear that is what I always did with the Kumho and I got decent wear out of them and my Spyder handled great. This was on the 2010 RT I was about to change the tire on the 2013 but didn't get a chance.

WARNING: If you use non-stock tires, you MUST remember to change the air in your tires every 5,000 miles. Failing to do this will cause rubber gasification to accumulate inside the tires.

:hun: I will just use nitrogen when I change over:thumbup:

I use a special mixture of 78% nitrogen.

:shocked: I have a 10 gallon Nitrogen generator in my garage then :roflblack:

What is tire rubber gasification? How does 5,000 miles cause this gasification and how much and what type of gases accumulate? Is there a danger to the public? Is this why did you post a "Warning:"? We all need to know.

I'm running 17 front, 20-22 rear and with 10K on present tire there's no discernible wear in the middle.

I think theres something to nitrogen as far as not leaking; my Accord came with it and 10K miles and a year later all tires still have 33lbs and I haven't done a thing to them. Not something I'm gonna pay for tho...........

There is no need to pay for it. The common name given to the atmospheric gases used in breathing and photosynthesis is air. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen,[SUP][1][/SUP] 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. :yes:

The reasons for nitrogen fill are o2 causes rubber rot and can seep through rubber more easily than air. Proven facts. The observation above is also true it does not leak out like air and your pressure stays constant in temp changes. No more constant checking ( and in modern cars nor more low air nanny naggin). I have used it in all my Corvettes with great success. It was worth $20 to me I have wasted much more on getting fat :thumbup:

Here is a good place to start your research: Complete Study of the Pyrolysis and Gasification of Scrap Tires: http://pubs.acs.org/doi/abs/10.1021/es034608u

You should take this seriously as it is the next major threat to our climate. The only reason Al Gore missed it is because he is too busy eating hamburgers and getting "massages" in hotel rooms!


for those who get nervous, place one hand on each hip and have a belly laugh. You will feel better.

Yeah. You are right. However, the damage done by oxygen on the inside of the tire is negligible over the life of the tire. Moreover, nitrogen also reacts with the carbon compounds in the rubber causing degradation. The damage from that is also negligible. If you want to prevent any chemical damage to the insides of your tires you would need to use an inert gas. Helium molecules are too small, they would just leak out. You would probably be better off using krypton or xenon. The cost of filling your tires with that would exceed the value of the tires by quite a bit.

I only change the air in my tire when it gets dirty, am I ok? Now i'm worried... this sounds like a thread from the Goldwing forum.

Dirty air? I never trust air that I can't see.

...and don't forget that tires are no longer natural rubber, they are mostly nylon and similar products. Rot isn't the threat it used to be...not to mention that the air on the outside contains oxygen, and they can rot from there too. And should we mention deterioration from ozone and UV light?

The main reason for using compressed nitrogen is that the gas in pressurized cylinders is dry. Moisture causes more change in pressure and more "rot" than any other factor.

Dan,

You didn't answer my questions. You were talking about this: "If you use non-stock tires, you MUST remember to change the air in your tires every 5,000 miles. Failing to do this will cause rubber gasification to accumulate inside the tires". A person with two doctorial degrees, I though I get a better answer than that.
