Tire pressure? - Page 6 - Toyota Yaris Forums

ON my wifes CR-V it kicked in at 26 psi. Kind of a good thing. I found a screw in the tire. Without the sensor she might have driven the car until the tire was completely flat.

I dont think it sets the light based on a specific tire pressure but it compares all 4 pressures and when it senses one tire is a amount lower than the rest is when it sets the light.

Not true. If it was, your tires could ALL be at 15 psi and the sensor wouldnt go off?!?

Glad you recognized that as humor, I am sure some people might take it literally! I'm also glad you weren't hurt in that accident, it could have been much worse but I am sure the damage to your beloved Yaris was enough! It would have been for me!

Well, I drove to work with my tires at 40 PSI and I will admit that although it was noticeable, it wasn't that bad. The bumps are a little harsher, but they were already a bit rough with my lower-profile tires. And I don't know if I am getting any better gas mileage going from 32 PSI in my tires to 40; but I keep tab of that info at fill-ups so I will let everyone know my results. I am not going to do anything else different, so I will see how much better the increased tire pressure works.

Stay tuned!

Cheers! M2

From my personal experience, going from 50psi to 32psi, I lost about 2-3 MPG (highway), but the ride is sooo much smoother and the handling (especially in the rain/snow) is 10x better.

same here with lower p.s.i. , try to keep them hovering around 34 . If you notice harsher ride , car is telling you

of the abuse on your suspension as well . Tie rod ends , etc.. Which could / would accelerate the wear on those . Say if part of suspension became damaged under warranty and service center noticed the high tire pressure , they may not honor it . One or few extra m.p.g. not worth it to me .

Wow, I knew a thread about tire pressure wouldn't go well but I'm still surprised. Things have gone downhill since the hack.
