Hi all,

I have noticed that after I get my car's tyre pressures to correct amount, during the next check, the change in tyre pressures is uneven. Typically, the left side (passenger's) pressure is higher say by 1 psi than right. And front tyres have greater pressure drop than rear. Is it normal (due to driver's wt, engine wt etc)?

Yes. Depends on how long you go without a top up. Normally if you get it checked everyweek, there shouldnt be much difference.
If you do it once a month, you will definitely find differences.

Add to harishsegar's reply..try to fill air from one place only. No matter if their reading is correct or not. Atleast, you'll have a consistancy.

Uneven tyre pressure loss could be variously attributable to weak tube (if tubed-tyre), loose blowpin, air seepage around imperfectly attached/seated tyre-rim, microscopic punctures resulting in sedate air loss or elongated duration between subsequent air top-up.

as far as i know the left side weighs more,that might be the reason too

Exactly. That would be my conclusion as well, i dont think weight differences have much of an impact on this.

Question

Can someone highlight the consequences of having uneven tyre pressures? Especially uneven pressure between the left and right sides.

braking,
steering / handling,
bumpy ride
oversteer which can lead to spin
bearing, cv, arms etc slowly locha
