What tire pressures do you run?

PorkChop :o)

Is it recommended to increased inflation pressure to improve gas mileage?

I'm running my mazda with 34/34 psi (front/rear) although dun sa driver side door indicate that the manufacturer's recommendation is only 32 psi.

Nabasa ko kasi na it will help with your mileage and tire wear.

"The minimum pressure will give you a softer ride, at the expense of fuel mileage and tire wear. The maximum pressure will give you maximum fuel mileage and minimum tire wear, at the expense of a stiffer ride."

ano opinion nyo dito mga ka-pexers?

I use 36 on all wheels when the recommendation is 31. I know a friend who uses 40 psi even.

It really does help with mileage. If you're going out of town, though, I would suggest following the recommendation.

so city driving and hindi full and load ok lang itaas ang psi?

kapag full load (passengers and bags) dapat sumunod sa recommended psi level?

Effects of Overinflation

Over-inflating your tires as little as 6psi can lead to excess damage when driving over uneven sections of road and/or potholes. When the tire is overinflated, it cannot compress and spread impact over its entire surface. This will also lead to a rougher ride, as the tire cannot cushion the weight of the car as well.

Bulging Caused by Overinflation

Overinflation will also cause the tire to bulge out along the center of the treads. This will result in a decrease in traction and stopping distance, since less of the tire is contacting the driving surface.

Wear and Tear

When tires are overinflated, they will wear unevenly. This will cause more stress on the tire itself, which can lead to leaks and blowouts.

Fuel savings and tire wear would still be negligible IMO. Over-inflation also makes you prone to bump-steer. Keep the tire pressure within the recommended spec.

IMHO over inflation is quite dangerous as the contact patch between the vehicle and the ground is reduced. If ever you will need to brake hard, there is a possibility that the vehicle will just skid on the road.

I use 27 for the front / 29 for the rear on my SUV, 30 for both front and rear for my weekend car and 29 for the front / 30 for the rear of my daily driver.

They're all manufacturer recommended tyre pressures and though my tyres and rims are aftermarket, I kept the same tyre sizes.

If you ask me, the wear and tear on your suspension as well as on your steering isn't worth it considering our city's roads aren't smooth.

However, if you're a hypermiler who just want to squeeze every mile out of every drop of fuel you put in, then I guess every little bit of savings count.

32 on all four...2007 honda city

Karaniwan 30 psi, amximum at 32 psi, pero binabababaan ko hanggang 18 psi depende sa terrain.

gotta lick it

^ 30psi

For my 195/50/16 tire I use 31 psi. My FC and ride improved.

I forgot to add that if you're fussy with your tyre pressure, you should use nitrogen instead of ordinary air. Nitrogen doesn't expand like normal air so it is far more stable.

sobrang baba naman ata chip ng 18psi? anong dala mo?

24-25 psi for my vitara. Suzuki recommends 23 psi.

I usually go to roadstar at the fort. If I remember correctly, it's P50. I also go to GTD off Banawe street in QC sometimes if I'm in that area.

Good tyre shops should have this.

Ano yung 50? Refill o vacuum? Sa iba kasi 100 per gulong pag vacuum muna, 50 refill.

K.I.L.L.

That's a refill. I forgot about the vacuum since I've been using nitrogen in my tyres ever since I got them.

Just for everyone's information, if you want to use nitrogen, you would have to take out the old air in your tyres hence the need to vacuum it all out. You will not achieve the results of stable pressure in your tyres if you mix nitrogen with ordinary air.

How often ang pahangin mo sa nitrogen? Tuwing ilang km?

I check my tyre pressure every 3 months. I top up every 6 months with nitrogen. Before when I used normal air, I topped up every 2 weeks. A good buddy of mine tops up with nitrogen every 2 months but he's a lot more fussy than I am.
