Tire Pressure

[Leotardtearer22]

Hello, I have a 2006 aveo just bought used,with winter tires on it half used. I'll change them soon in a few weeks, but for now should I keep the pressure at 30psi like it says on the door in the summer or more for psi?

I thnk you should probably keep around 32-35psi.

[Leotardtearer22]

ok thks even for the rest of summer until end of September? Hopefully I won't have to wait that long,money wise I mean.
Is there a reason why it should be at 32 or over and not the posted 30 on door?

Thks again

The only reason I up mine a few psi is for less rolling resistance, which in turn might give you slightly higher MPGs and better stability

+1 for 32-35psi

psi is also relative to tire size..

but snow tires will not last long in the heat of summer.. save money by looking on craigslist for wheels and tires already mounted for less.

I guess I should have states that for mine it was on stock tires.
And you are right about the snow tires, cuz they are a softer compound.

I run my psi at around 41 PSI front and back. Supposed to save gas. so far its has been noticable. 1.5 to 2 MPG gain. Your RPMs run lower so i assume thats where the fuel savings come in. Its called LOW ROLLING RESISTANCE. I might have read that here though

I never actually paid attention to the RPMs being lower but there's less tire touching the ground when overinflated, I used to run like 25psi on my GST at the track for better traction.

I'm guessing he's talking about RPMs of the tire itself as opposing to the RPMs of the engine.. larger diameter of the tire (by inflating it)=lower RPM number... that's just a guess though.
