No speeding no such problem. Straight 250.

May be too high if you are driving Japanese car. The recommended number is at door side of driver seat.

If you pump 260, it's normally 250 right? Cos some air tend to escape when you take out

base on tpms reading....no.

Really? When I plug in to pump again, it read around 250.

 

[sneggg]

How often u all pump?

I pump air and it lasts at least 4 months with 0-5psi pressure drop. Tyres should not lose pressure within a month. There should not be a difference in terms of air leaking whether u use air or nitrogen. I know many claim otherwise and are happy N2 users.

Anyway I gave up nitrogen because it made no difference to me. If my tire loses pressure in a month, chances are its got a nail, so I will remove the wheel and repair it before putting it back.

From personal experience on my own tires, there was no significant improvement patching from inside compared to using tire strings. If the damage was too big, I will replace the tire. If it was small, tire string works very well. As good as permanent in my hands.

For the manufacturer's recommended tyre pressure, what temperature is it rated at~? And what is the compensation required for every degrees celcius deviation from this rated temperature~?

 

[tazzi80]

Only pump tyres once every 3-4 months. It doesnt really drop. I have a tpms which reads the pressure.

I pump whenever there is a drop of more than 2 PSI when cold as reported by the TPMS. Usually have to pump every 2 weeks, using a portable tire air inflator pump at home at my convenience.

They are rated at cold tire temperature, meaning tires not driven left overnight same temperature as ambient air. Ambient temperature will differ from location to location, eg Genting Highlands vs Singapore. Just pump accordingly at the location's ambient temperature should be fine as long as don't under-inflate or over-inflate, meaning tires are of a minimum pressure as per manufacturer recommendation.

Always a good practice to check the cold tire pressure when travelling between locations of different ambient temperatures, eg after overnight in Genting Highlands check in the morning increase pressure as necessary, upon return to Singapore check in the morning after reduce pressure as necessary.

Hope this helps.

If I use normal air, about weekly pump once.
Nitrogen can last a bit longer.
There is nothing wrong with the tyres, it is the usage.
