Optra Tyre Pressure

[Divemaster]

Hi,

 

Am wondering what pressure you're putting in your tyres... Does anyone know what's the maximum pressure allowable and what happens if you pump in too much air? Will the tyres "burst"?

 

I'm pumping 235 for both front and rear, but my front passenger side seems to be losing air more often then the rest. Other than that, it's more bumpy but the road holding on cornering is much better than 220.

I also feel soft on front wheel if pump 220, so I pump 240 for front. But don't know whether it is good for long run.

I always pump 240 all round for my tires..

 

but realise almost 1 ~ 2 weeks will drop to 220

Logically, the front should have 230Nm and the rear 200 Nm. This is because the engine in front contribute alot of weight and the tires needs to be pressurised higher to meet with the load whereas the rear ( if no passengers at the back ) needs less pressure because of the weight distribution. If tires are pressured higher, i.e. 240 Nm, the contact area of the rubber would be less. Less rolling during corner but contact or adhesion to road is less.

 

Me, I pump 230 front and 210 rear using a 185/60 R15 setup !

 

Cheers

Hey, my front passenger side also lose air very fast..

Every time I pump petrol, the PSI drop from 235 to about 210...

 

The rest still quite ok.. I thought I damaged that wheel, cos I scratched the rims before..

 

Look inside your glove compartment will give you the tyre pressure. Normal and MAX.

pump nitrogen than u can get constant pressure...

Been pumping 240 all this while anf for my previous cars. The handling is better but got to rotate ocassionally. the middle thread would wear off faster than the side.

Curious, you pump 240 when tyres are cold or when they're hot?

[Topgun7557]

At night or morning - meaning when the tyres are cold. No expansion

[Room430]

OIC...... wow, that's kinda high, I usually pump around 245 when I've driven for at least 10-15mins on my way to work.

 

I agree the handling is better

Since ur middle thread wears off faster, means u had over inflated ur tires. Its danagerous as onli a small area is in contact with the road.
