Tyre Pressure

[Myprecious]

Hi Guys!

 

Just wanna check how much air do you usually pump into your tyre? Do you pump it to the maximum possible pressure as stated in the manual?

 

If the manual says 210 to 230KPa. What would you choose and why?

 

What is the effect of pumping it to the maximum pressure? Any negative effects?

 

 

 

Cheers!

wat happen when u eat too much

For me, determining the correct tyre pressure involves a lot of guess work and trial and error to come to a pressure that feels right.

 

I went to read what other users of my model have to say with regards to the tyre pressure and which combination they felt was good. And then I tried it for myself until I arrived at a pressure which was to my liking and comfort.

 

So if your manual says 210 to 230 kPa, you may want to try 210 first, then 220, then 230 kPa. Then decide which feel you like best and stick to it. Also monitor your FC. It may be affected by the change in tyre pressure.

Jus for your reference, i'm pumping 250kpa onto my 215/45R17

 

Pumping too much will have better FC but the grip of your tyres will drop

My manual says 190kpa but I pump 200 kpa cos I feel the best grip & comfort at this pressure.

 

When going on long journeys, I pump 205kpa front & 210kpa for rear.

 

This to compensate for the longer drive(hotter tyre) & the extra weight(4 pax & luggage) with a fully loaded car.

I agrees with the other guys. However I would like to caution everyone. Don't over inflate your tyres, especially if you're driving long distance & the weather is hot. As the air get heated, it will further more over inflate your tyre. I guess you know what might happen if it gets too high... (Don't take my words for it)....

The manual gives u a range cos different countries have different road conditions. So look for the one within range to suit yourself.

 

I give u an example:

 

I own a bicycle, when I cycle on tarmac I would inflat the tyres until hard hard so that it takes less effort to cycle. When I cycle off-road I cannot have hard hard tyres whao, if not I'll keep slipping and fall. I have to deflat thema little to have more surface contact.

 

In your case the difference is negligible.

So i recommend u pump nitrogen gas in your tyres.

The advantages are:

 

1) Unlike normal compress air it does not expand on high temp.

2) It does not contain moisture hence constant pressure throughout gives u better FC.

3) More comfortable ride and less tyre noise produced when driving.

4) Dun have to monitor tyre pressure so frequently too.

 

My ride Honda so Kah motor provide this service. It's a pay one time thing($40 for 4 tyres). So anytime u change tyre/s for any reason can go without appointment and refill.

agar agar ..

 

but really, i suppose the manual is there for a reason.. stick within the range

I got FREE nitrogen gas top up when I changed my tyres at CAS.

260kpa for track all 4s

 

230 front 250 rear - street

Does pumping up your tyre more really change your FC by alot?

u forgot to add that once u r on nitro, u can go back to normal petrol pump liao..

[Qpik]

for me, as my tyre is stock i follow manufacturer's recommendation.

 

on top of that, i purchased a gauge to ensure pressure is correct at all time.

 

lately, i noticed that i hv to pump fornightly maybe cos i travel quite frequent & also the digital pump at petrol kiosk is not that accurate.

 

on top of that, i understand fm other forumers that it is best to pump more on hot tyres & check yr pressure on cold tyres.

To be honest, I think the improvement is marginal.

 

At the track I pump it to 260kpa to strengten the side walls. My car being AWD has the tendency to chew away the outer side of the tyre with a few cornerings.

 

At the moment I'm running with -1.33 deg camber. Will be changing to -1.5 and bring it to the track and try again.
