Re: Tire Pressures, which day?

[Spicemanii@xxxxxxx]

Tire pressures depend on what day it is. 

?? If I am racing on a road course with street tires, I run 44 pounds or the maximun on the sidewall for less wall flex. Tire mileage is not important here. 

?? For a smooth ride, non performance, you can run below about where tire shops put them. But, the tire will wear on the outer edges. The tire will run hotter. This is also less gas mileage. 
?? A hard tire, riding mostly on the center of the tread will have less roll resistence and better mileage. Less horsepower to get to speed. And, it will wear out the center of the tread. 
?? If a tire is riding with the pressure such as to have the load spread out evenly across the tread will wear longer and evenly. 
?? So, what is your preference is what you use for tire pressure. 
?? A front engine car will have more weight there ad could use a couple more in front than the rears. 
?? The best way I have found is to use a laser temp gun and drive the car about 5 straight miles, no curves. Take a reading across the tread, assuming you have the correct alignment, and adjust according the the readings. Center hotter than the edges, lower the pressure. Edges hotter, raise the pressure. Both situations require a couple tests and air pressure adjustments. 
?? Towing also makes a difference. Passengers, a load in the trunk, etc.??? joe machado

Hi,

What tire pressures do you folks run your radial tires?  The owners 
manual of my 64 Dodge call for 26 and 28 psi (belted tires).

Do we ignore the listed pressures and go with 35ish that is more normal 
on newer vehicles?

I use 35 psi but never asked this question before.

What do you think?
