Tire pressure

[Robertmx3]

I've heard it would be better to have higher or lower (can't remember) tire pressure, at the track, then normal.

What & why is this??

I'm going to give you a few min. to rethink that question......then you can tell us what "you" came up with.

not trying to be a wise guy here... just want you to see if you can figure it out.

Depends on the tire.. a regular street radial, you actually want more pressure, as your average radial will cup in the middle under low pressure, causing less contact patch on the ground, and be unstable at high speed. A drag radial or slick you want less pressure.

[Robertmx3]

Well, because there are 2 options I don't know

High pressure means less contact with the ground so less friction
Low pressure means more contact with the ground so better grip

***Is it such a noob question?? ***

you never said what tire your using.. so it would be usefull to know.
JAMZ pretty much sumed it up for those type's of tire's.
now with a slick your looking for "footprint" you'd start with the recomended tire pressure from the tire Co. and work from there giving you the largest "footprint".

I've got all seasons and I have the pressure at 25psi.

Been cutting consistent 2.0 60' times with one 1.9 60' time.

The tires are just normal street tires. Marshall is the brand (don't know the type)

Find a clean patch of concrete. do a burn out, see results. Add or remove pressure try again. you are looking for the widest, darkest contact patch. As I stated earlier a regular radial tire will like alot more pressure than a DR or slick. Start @ 30psi and go up/down from there depending on the patch. Keep in mind burnout duration will change the tire psi as heat is generated adjust accordingly :) If all of this is happening on an mx3, then disregard... all the burnout in the world won't help it :)
