how does this work?Originally posted by the Bear:you get a little tyre gauge.. the old ones look like this:
depends on the tyre itself....Originally posted by dibilo:er 1 more question... what is the correct tyre pressure for a car??

underinflating...ure fc worsens.....over inflating...erm..u try first...heheheOriginally posted by Drain-V-:How about are the effects of under-inflating and over-inflating the tires?

Under inflating will cause your FC to increase while over inflating will cause you to lose comfort over bumpy roadsOriginally posted by Drain-V-:How about are the effects of under-inflating and over-inflating the tires?
wow.. rather comprehensive! thanks!Originally posted by Praetorian111:For new sets of tyres the tyre pressure will not drop significally. Therefore you do not have to check the air pressure frequently... once in two weeks will be more than enough. however, it is always a good practice to check the external outlook of the tyres to see whether it is deflated by mischief or by sharp objects or prematured wear and tear.
Checking of air pressure can be done using similiar the instrument as shown by 'the bear' or in my case mine is a pen like instrument. However, to save time the easiest is to go to petrol station set the pump to the pressure and just pump the air into the tyres.
the tyres pressure is as recommended is written at the side of the door.

erm.. does it cost anything to pump my tyres at the petrol station?
I know the numbers behind are one of the two measurements of air pressure available at the air pump station. I do not know about the numbers in brackets, but they looked like 1/100 measurements.Originally posted by wuming78:then below that there is a picture of the car, with arrows pointing to the tyres. so i interpreted it as:
front tyre: 220(2.2)32
back tyre: 210(2.1)30
spare tyre: 240(2.4)35
i guess 220, 210 and 240 are the pressures (You are very correct!). what about the numbers in the parentheses and the numbers behind?
thanks!![]()
what about my questions?Originally posted by Manager433:Let me, a 'semi-retired' SAF Driver with 13yrs of driving experience share with newbie some info on checking tyre pressure. No need to think so much till your head crack.
Look at the front pair of tyre first. You should noticed the marking of the brand / maker on the outer surface, the diameter and the correct tyre pressure to pump in. Front and rear tyre different pressure. Take note. Also take note different brand of tyre differnet pressure.
Over inflat will cause your car to skit when E-brake apply. Under inflat will cause your tyre wear out faster.
Wish all a safe journey.![]()
1. Tyres will expand and contract, and after some driving the tyre is hot and expanded. Maybe you pumped it at 210 while it was hot, then it cooled down a little, contracting and making the pressure higher?Originally posted by wuming78:anyone knows about those figures?
i just went to the petrol station to pump my tyres. it was easy! but i have to ask a few questions again:
1. i set the pump to 210 and pumped my rear tyre. when it hit 210 and started beeping, i removed the pump. but i went to try pumping again, and the figures on the display went on beyond 210, so i removed the pump, then pumped again. this time it started below 210 and stopped at 210 again. would this cause the tyre to be "overpumped"? or would this be prevented by the setting on the pump? any way of checking if the tyre is overpumped?
2. how often should i check my tyres then? everytime i pump petrol? anyway what would cause the tyre to lose air?
thanks!
175/65R14 82TOriginally posted by wuming78:i found the label beside my car door that gives information on the tyres. but i need help interpreting it!
the first 2 lines goes like
175/65R14 82T
175/65R14 82H
kPA (....) psi
then below that there is a picture of the car, with arrows pointing to the tyres. so i interpreted it as:
front tyre: 220(2.2)32
back tyre: 210(2.1)30
spare tyre: 240(2.4)35
so my questions are:
1. what does the first 2 lines say? kPA is the unit for pressure, but 175 cant be the pressure rite?
2. i guess 220, 210 and 240 are the pressures. what about the numbers in the parentheses and the numbers behind?

Tyre temperatures and pressures tend to increase in direct relation to speed and load.Originally posted by wuming78:2. how often should i check my tyres then? everytime i pump petrol? anyway what would cause the tyre to lose air?
thanks!
oops!Originally posted by zenmaster:Tyre temperatures and pressures tend to increase in direct relation to speed and load.
For this reason the tyre pressure should normally be checked/adjusted when the tyres are cold. My car manual advises that the pressure should be checked only if the car has travelled less than 1.6km.
