I recently read;

And they have a section on tire pressure about factory labeled vs tire rated. I was wondering if anyone has experiences with using the 10% max rule with the tire recommendation vs. the factory with aftermarket tires.

Thanks!

 

Can anyone give some recomendations? I'm just wondering what other people are doing.

 

i normally run about 3 to 5 psi more than the recommended tire pressure, depending on car. I have run as high as 44 psi on one of my trucks but when running though a puddle at the gas station i noticed that at that pressure the tire didn't have complete contact with the road and dropped the pressure back a bit. I also recommend to run atleast 2 more psi for every inch larger wheel than factory.

 

This is for daily driving. Drag race drop the pressure a bit and road race bump the pressure up a bit.

 

i try to keep the difference between the fronts and rear as recommend by manufacture but i usually run 2 psi more in front and 3psi more in rear unless during auto cross then i run 41front 38psi rear

 

I run enough pressure on the fronts to keep from rolling over the shoulder of the tires. On the rear, I run whatever pressure to fine tune the handling.

 

I usually run 3-5 psi more than recommended....like the last guy said to keep from rolling over the sidewall and to get a couple more MPG's
