u mean if the day is sunny, u'll go to the petrol station to pump 240psi and once it rain, u'll go back to the petrol station to let go to 230 psi and when the rain stop again, u'll go back to pump back to 240 psi??? (joking) Some say too much Psi is not gd for tyres, lets see wat pressure other bro pump...

Standard is 220 as stated on most cars... but most pp will pump 230-240 cos will not need to go and pump again so frequently...

i pump 250 on all 4 wheels and can say it does save a bit of fc. Well, try not to cruise beyond 2500 rpm and above in order to conserve fc.

Mine always pump at 230kpa 195/45/R15 Oh coz my is stock steel rims so i pump 250 each wheel lor... I know 230 is good but it seems to consume fc more. What's yr opinion?

250 kpa not tat good, cos if no shock absorption, parts may loose or wear off faster.

(joking) Some say too much Psi is not gd for tyres, lets see wat pressure other bro pump... bro, not that, once the weather changes the presure has to be reset. it's to compensate for expansions and contractions due to changes in temperatures. usually i pump my petrol and air at night.. so it's always pretty cool.. think 240kPa is already quite high.. becareful of uneven tire wear, ( center of tyre wears off faster) and overinflated tires might run the risk of lowered levels of traction... but i myself run on 250kPa.. haha.. FC better... =)

Hi,
I am using the stock 14 inch rims with the Yokohama 165/14 tyres.
I found that the front tyres seems always looks flat. Is it because the front is heavier (engine)? It seems that partial of the front wheels "side-walls" are also in contact with the road. The back wheels looks OK.
Should I pump slightly more air for the front?

230 for the front and 220 or 210 for the back

For me, I tried 230 and 220. 230 running on smooth road okay, other than that bumpy. 220 better option all round, comfort, even wear, wet and dry driving.

You are taking some risk , bro.... by jus saving jus a bit of fuel... yeah.. taking a bit of risk.. but i pump that cuz the car seems to pick up easier.. like less resistance to move off.. but personal preference la.. =) cuz when my pressure is about 215-220, the car seems very heavy off the line.. think the thinner your tire track, the higher pressure it should be for the same car..
