mahirap kasi kung di mo susundin, you're sacrificing the thread life and your safety.

Ahh. Sa Adventure ko kasi halos lahat ng nakausap ko na advie owner hindi nila sinusunod yung recommended na 26 front 36 rear. Karamihan 35 front & rear or 30 front 33 rear.

as long as the specifications indicated on the tire's carcass are not violated, the tire should survive the experience.
but the over-inflation might figure negatively on the vehicle's suspension, etc..

but yess. over-inflation does seem to soften the steering feel..
i myself, add +2 psi ...

Feeling ko kasi parang over-inflation yung nasa recommend. Sa Adventure kasi 26 front 36 rear tas ang max psi ng gulong is 50psi. Samantalang to 36 front 33 rear tas max psi ng gulong is 44psi. Yung dating lancer ko kasi 30 front & rear kaya medyo nanibago talaga ako. Ask ko lang po pag hiway drive at the speed of 90-100kms. Ilan po kadalasang nadadagdag sa hangin sa gulong?

Masyado matagtag yung 35psi sa akin. I normally hover between 32 to 33 psi lang.

It is the ambient temperature that you should consider, not your driving speed.

1-psi/10F = 1-psi/5.5C

Morning temperature = 27C
Cold tire air pressure = 36 psi

Case 1.
Afternoon temperature = 32C
Change in temperature = 32C - 27C = 5C
Increase in tire air pressure = 5C x 1 psi/5.5C = 0.9 psi
Tire air pressure = 36 psi + 0.9 psi = 36.6 psi

Case 2.
Afternoon temperature = 40C
Change in temperature = 40C - 27C = 13C
Increase in tire air pressure = 13C x 1 psi/5.5C = 2.36 psi
Tire air pressure = 36 psi + 2.36 psi = 38.36 psi

So 36 psi sa front is safe even if ambient temperature is 40C.

Ohh i see. Pagkaka alam ko kasi pag mabilis ang takbo umiiniit yung gulong kaya tumataas yung psi.

Para hindi ka kabahan, buy yourself a tire air pressure gauge. Actually, dapat meron ka na nito.

Inflate your front tires to 36 psi in the morning and then after you use the vehicle, measure the tire air pressure again. At least yan, actual mo makikita kung umaabot ka ng 44 psi.

i thought inflating psi is measured with a cold tire...

"Inflate your front tires to 36 psi in the morning" >> This is the cold tire air pressure.

"and then after you use the vehicle, measure the tire air pressure again." >> This is the hot tire air pressure.

The purpose here is to know the maximum air pressure inside the tire during normal use.. since according to radz15, tire sidewall indicated 44 psi as maximum for his tires.

isn't the 44 psi max tire sidewall, also measured as cold inflating pressure?
