Tire Pressure

[Daox]

The steel belting in the tire doesn't allow the tire to grow in diameter any amount that would be noticeable.

The reduction in rolling resistance is from reducing the flex in the tire's sidewall. The reduction in sidewall flexing also leads to quicker steering response.

This is also why underinflated tires are dangerous, they flex too much, heat up and eventually fail.

For my daily drivers, I run my tires at or above max sidewall pressure for better mileage. If I were looking for the best handling, I'd probably run somewhere between the door jam pressure and that. The door jam pressure is the OEM's recommendation, and is a compromise between handling performance and giving you a smooth ride (since the flexing does absorb bumps).

THks for all replies it makes sense, running at 32 right now.I am looking for all season tires but see alot of 1856514's ,but less choice in the 1856014's,which is the aveo size. Why is that ?

more popular tire size? it's the civic's stock tire size, and there's a lot more civics out there...

185/60r14 is what came stock on vw's for @20 years. its considered a "european" size by ntb, firestone, and sear. ive heard about excused like that too many times.

Dont let them bs you. That price should the same and the availability is there.

you can run the 185/65r14 if you want as well it is less than 10 mm in sidewall difference.

Thks so no problem running 65's on the aveo's? No problem finding those.

it actually almost the same outside diameter as the 17" tires everyone likes to run, so unless your really low. or whipping the car around corners at high speed, they wont rub. the speedo will be off buy 3%, and you'll be going further that your odometer shows by 3% as well..
