If you over inflate without the factor of heavy load then you cause the tire to assume a more rounded, or U shaped profile. This causes less of a contact patch/profile in relationship to tire on the road surface. I am not an artist by any stretch of the imagination so try to imagine the difference between this ) (over inflation) and this ] (correct inflation) in relation ship to contact patch with road surface. Which would you consider more stable?

psi
Quote:
My sedan tires do say 40 psi max but i found a link on the tire manufactures website that said 44 psi - i have since (for the last 6 weeks/2000 miles) been at 44 psi - I would say the improvement has been about 50%. I have looked at other message boards (including ones for the prius - which comes with the 185's on them as well) and it seems that upgrading to 195's makes a big difference (not sure if that's really true or not)...apparently, corrolla's also have this problem as well. i'm going to keep my current tires (like you, strapped for cash) until late November and then upgrade to 195's - as the 160 tread on those stock tires doesn't cut it in the wisconsin winters... |

Yes, but the general consensus is inflating to the stock tires max sidewall pressure, whats printed on the side, is a good thing.
im not talking bout over inflating to 50-60psi. In all honesty, the interstate driving is killing me, and I cant spend any money really to fix the problems with new tires or tweaking the suspension. This just seems like a good no cost solution. |

I run 44psi and I agree with blacksan, traction is not as good (stopped fast today and one tire slid on gravel because I had a big load in back) but think the sidewall flex is much less. My springs cost $117 and an afternoon in the garage....firmer than some people would want, but even with the 1.5" drop I think the stock springs would bottom quicker (I bought the LB so I could carry things).....tires are behind cruise control and scangage on my list.

"has me scared to drive on the interstate now"
"60-80mph the car is ALL OVER the road. almost uncontrollable" "barely made it home from the dealer" "the interstate driving is killing me" C'mon, if the Yaris is such a liability, the DOT would never legalize it, hwy fatalities would be all over the news, Toyota stock would plummet on the bad press... There is nothing wrong with this car and NO you don't have to TRD it to make it track straight. Did you guys come from a Lexus LS or Bentley? making the Yaris so hard to get used to? Sure the Yaris is buzzy but it's damn smooth for a sub 2300lb car. Short wheel base? same as the Fit. I also have a Jeep wrangler with 93" wheelbase and high CG, I've passed semis doing 85mph in Texas crosswinds Quite frankly y'all don't know how good you have it. ON a serious note, if you're really scared to drive the Yaris on the hwy you need a new car. Dont' mess with tire pressure or feel you have to lower it 2" to feel stable.

But since I am carrying a 2 year old in the back seat, the car should not feel like im driving drunk if I take the interstate. Say what you will about me, i dont care too much. I have driven a 86 626, suburu loyale, taurus, f150, small japanese box cars when i was there, and a ranger. Small cars, big cars, none of them have handled like this at interstate speeds before for me. Sorry if I'm a bit concerned for the safety of my family. |

My yaris seems to hit a sweet spot when it hits 80 and drives as smooth as silk. Don't know why you'd be having problems. Sometimes when the wind picks up over 20 miles an hour I can feel a pull.
Mines a stock yaris hatchback. My tires are at 36psi. |

arcath, the high PSI you where reading was most likely from warm tires. You need to check them cold to get proper PSI reading.
You have every right, and obligation to keep you family safe. I was not trying to slam you in the least. I drive for a living and am very sensitive to all matters concerning vehicle performance. My observation/reply was based on professional experience going back too 1983. I am not the keeper of all knowledge, but just trying to pass on some observations. |

If you are concerned with your family's safety , take driving lessons...... The yaris is fine
The next time it rains , and you have to apply the brakes in a hurry , you won't like whats gonna happen . GO BACK TO STOCK PRESSURE , for your family ........ |

Forget about all the tire pressure BS... Even with stock tires, tire pressures, and suspension, it should track straight and consistent at 80 MPH. If your car is as squirlly on the interstate as you say than there is somthing wrong with it. Take it to the dealer and make them fix it. I know it's not what you want to hear, but it's their problem, not yours.
