Anyone understand how plysteer affects vehicles?
My questions:
If plysteer is present in all tires, pushing to the left, and it compensates for the road crown, why isn't it a problem in places where they drive on the left side of the road, like the UK?
What about on flat roads? Is plysteer...
Does anyone know if any vehicle manufacturer still requires their wheels to be bored off center in order to compensate for tire uniformity?
BACKGROUND: Automotive wheels pilot on the center hole of the wheel rather than on the lugs. Some time back some vehicle manufacturers would have their...
I am in the middle of a discussion on DOT tire testing and the subject of wheel tests has come up. A quick look at the FMVSS regulations doesn't seem to reveal any testing requirements for wheel and rims.
So, is there a DOT test for wheels? If so, what is it?
If not, what do wheel...
Popeye427,
I see you've just joined, and you have expertise in an area I need to confirm some things on.
Tires on trailers tend not to have enough load carrying capacity. As a result, it is common for people to go to higher load range tires and use more pressure to increase the load carrying...
I've fielded a question in another forum concerning the use of high pressures on Pickup truck wheels. Specifically, if an LT type tire using its max pressure of 80 psi were to be put on a wheel designed for P metric type tires (35 psi!), would the wheel be able to stand up to the increased...
I have been conversing (discussing, arguing, what ever you want to call it) about using tire pressures above the maximum written in the sidewall. This is a technique that is being advocated by "Hypermilers" to gain fuel economy.
As a tire engineer, my gut goes all out of wack just thinking...
As you have no doubt noted, RunFlat tires are becoming more commonplace. They are reportedly much stiffer than conventional tires and that causes some ride complaints. How does the spring rate of a tire affect the Spring-Mass-Damper system we know as the vehicle's suspension. This question...
