Floaty feeling at higher speeds common?

Whoa!...30 PSI?
I dont feel bouncing at any.The ride is pretty tight.Maybe you had worn dampers?

I will get shit mileage at 30 psi?

The information I provided was when my '07 was new and I was experimenting with tyre tread patterns and tyre pressure.



Here's recommended tyre pressures for the Yaris: http://blog.toyota.co.uk/toyota-tyre...ze-guide#Yaris

Tyre Pressure:

14-inch wheels (175/70/14): The front tyres should be inflated to 36 psi. The rear tyres should be inflated to 35 psi.

15-inch wheels (175/65/15; 185/60/15): The front tyres should be inflated to a minimum of 33 psi and to a maximum of 36 psi. The rear tyres should be inflated to a minimum of 32 psi and to a maximum of 35 psi.

16-inch wheels (195/50/16; 205/50/16): The front tyres should be inflated to 32 psi for speeds below 99mph and 35 for speeds above. The rear tyres should be inflated to 29 psi for speeds below 99mph and 30 for speeds above.

WOAH! i played around with pressure alot on my car and i ended up with 33 front 31 rear just last week because the car didn't feel right!! I didnt know i was so spot on lol. (sw connecticut highways go from 70-110mph cause everyone here drives high end german/italian no one gives a damn lol.)

Alright then.I will give this a go when tires are cold in the morning.

32 and 29 psi.

Looks like the tire place just went with what was on the door jam.

Not sayng its uncomfortable.The car stays true as in zero pull.No vibrations.

New Tires are on correct with new KYB shocks.

I ckecked pressure cold last night 32 all round.These are not super sticky tire and many use this exact tire and are pleased as am I.

Perhaps Iam just not used to the yaris at higher speed?

The car drives absolutely firm amd feels really responsive.Really,really impressed overall.Drives nicer then a new fit and civic si which are both 2016 and I have driven both.

The civic feels like a boat and the fit just feels cheapish,kind of like a chevette,pontiac acadian or escort I once owned.

Could a bad stabilizer bar(One that connects to front shock absorber) cause issues like I described.

I think that is rattling.

I have new cv drive shaft going in this weeekend due to torn boot so i will have mechanic give it a thorough go over.

No, but you're tires will last longer and you'll get better traction out of them.

This car gets decent enough gas mileage, I don't understand this infatuation with squeezing an extra couple of miles out of a gallon. Most of the time it's at a sacrifice to handling or even safety.

There is a balance to be achieved when it comes to tire pressure, enough to maximize the mileage, traction and handling. If you increase one of those factors, you decrease others. Simple physics.

Going to go 32 and 29 front/back.

Thanks for insight.

you don't buy Michelin Pilot Sport 3 tires to get better fuel millage.
if your goal is fuel millage you buy those silly low rolling resistance tires.
if you buy performance tires, your goal should be maximum performance, otherwise save yourself $200(USD)
