Hi,
What's the recommended tire pressure for Hankook Ventus v12 K110
235/40/18 in the front?
265/35/18 in the rear?

Thanks,
D

what does it say on the tire?

[Mr. ///M3 RD]

The PSI listed on the sidewall of the tire is the max cold pressure for the tire carrying the highest (weight) load the tire supports.

Increase the cold tire pressure if the car will be carrying a heavy load or driven at high speeds for long times.

Cold weather will reduce the air pressure, warm weather will increase the air pressure - it is important to recheck tire pressure when the seasons change.

Additional fuel economy and improved steering response can be obtained at the price of a firmer ride if the tire's inflation is increased above what is recommended by the car's manufacturer. This shouldn't exceed the max pressure listed on the tire's sidewall. Test the car to see if its driving feel is improved.

If the car has to be driven to add air note the pressure before driving away. Then add the difference above when the reading is now. For instance if you wish to inflate your tires to 35psi and they're reading 30psi cold. The tires are 5psi underinflated so when you add air after driving and they now read 33psi adjust them to be 38psi. They should then read 35psi when cold.

Sunlight heats up tires even if they're not driven. For more even readings take note that not one side of the car has sun shining on it.

Tires cannot be "eye-balled" for pressure, particularly modern radials. Always use an accurate gauge.

For your tire size I would say front 36 and rear 38 (I would not exceed 40 PSIG).

Beyond that I recommend you make a Google search "Correct Tire Pressure" You will come across a formula and it will make crystal clear the correct tire pressure to be used. In closing I can only add check it often (weekly under similar temperature conditions).

The tire will only give you the maximum allowable tire pressure.

I'm running 38 psi all around on my Hankooks.

Forget the pressure listed on the tire - it is a maximum only.

Look at the placard on your door jamb or your owner's manual for the nearest tire sizes & use those pressures as a starting point.

Anywhere from about 36-38 PSI works great for me. I recommend playing around with it depending on your driving style and weather condition.

Considering purchasing some Hankook V12's as well for the daily. Are you happy with the tires and the performance thus far?

[EZ_TUR90]

im doing 36-38 in mine

agreed, I set my tire pressure up to 38 psi.

Decent for daily driving but they're not that great. Maybe I've been spoiled by Michelin PS2s.

Thanks every1 for the PSI recommendation.

I like them. I chose them because of where I live (HCM city).

I've recently changed the suspension. & for the last couple of nights (2 - 3am when there's no traffic), I usually sped upto 60mph & then squeezed on the brakes real hard to help settle the suspension.

I noticed the tires give me plenty of grip.

Noise... I hear honking & scooter's way louder than anything else from my car, so I cant tell a thing about tire noise.

It starts the raining season here, & in wet, the tires perform just fine. no problem with the grip (because of slow traffic).

It's sh!tty roads, with mad traffic, & slow speed here. I can't go that fast. So, in general, the grip of Hankook V12 is more than enough for me.
