Tyre Pressure
-
Hello all,
Currenly I am driving a GM Daewoo Kalos 1.5 with 14 inch tyres - 185/65 R14 86H. I would like to ask the folks here what would be the recommended tyre pressure. As some of you know, proper tyre pressure can help save some fuel since the car will not be 'dragging' itself. The original tyres was 13 inch and the base much smaller. My father changed to the current ones about a year after the car was bought. The car's manual indicated the original tyre pressure to be 210 psi. The car will be in its 6th year now. Thanks for reading.

typically its 30 to 35psig.....
210psig...i dont think so

Think TS meant 210kpa. 210-220 kpa should be just fine.

Use 32psig if you want to have a comfortable drive, cos that's what I'm using I think.

ah! been reading psig for too long :)210KPa = ~30psig

next question is when to pump.
pump less on a cool night?
pump more on the hottest afternoon u can find?
and of course, a short drive from start when the tyres are still not that warm yet.. -
car ur car manual or agent. Some cars have different requirement. The old mazda 2 is 190 behind n 210 in front.
And sinicker, it doesn't make much different one lah. End of the day fuel consumtion depends more on how u drive then this little difference in pressure.

hey all,
yah my mistake, was supposed to be in kPa, not psi. 210psi my tyres will explode already.
thanks for the correction. -

Similarly whenver I pump 220kpa at night or very early morning, when I pump in the afternoon the meter will read 235kpa.
Not that I have a fetish for pumping air, but I inflate the tyres about once a week as a habit and I always do the twice-approach as above, ie (night pump + next afternoon check / afternoon pump + early next morning check) - so as to be sure I don't have a slow puncture as I've a bad experience involving slow punctures. From outside may look ok, but there was once I was running all day long on a slow punctured tyre which had only 54kpa at the end of the day before I realised - I totally ruined the tyre + sidewall. Very lucky never explode.

i check the tyre pressure regularly, take public transport if the destination is prone to jams, plan my routes well...
and am very proud of my more than 13km/l fuel consumption on a mazda 3.

Just to add on, the tyre pressure will also depend on your tyre profile and your usual load requirements. There is no tyre pressure magic number or "one that fits all".

and am very proud of my more than 13km/l fuel consumption on a mazda 3.Wth! And I used to get 10km/l on the last gen Altis back when I was still driving.
Sinicker has proved that Mz3 has better FC than Altis
