Tire pressure... now that it is cold...

[criz]

I looked at my tire pressure the other day after not checking it for 2 months and all 4 were 22psi... I suggest you guys check your tires and adjust accordingly.

FYI: STi's require 36psi in the front and 30 in the back.

haha my truck had 15psi....no wonder

thanks for the heads up! :)

dont mention it ;)

criz if you are having any understeering problems think about switching those numbers... slightly lower pressure in the front and slightly higher in the rear... maybe 32-34 front and 36-38 rear :wink:

no understeer probs at all... i couldn't believe that Subaru wants lower pressure in the back by up to 6psi. Strange huh?

The other day I thought I was being cool by putting all 4 tires @ 40psi during 55degree weather.

Tonight i'm going to put the pressure down to what Subaru recommends and see how it feels.

I swapped out my wheels and tires for tank treads in the winter. :mrgreen:

I'd be cautious of too much neutralizing of the car. It is colder now-people generally want less of an oversteer potential with the precipitation on the ground.
But then again, I'm sure 4wd & Rwd owners look forward to this stuff.... :lol:

-be safe!

PS - why would understeer be classified as a 'problem'? :lol:

I dunno this **** sucks, after some spirited driving the other night with Sisforsurfing going around a turn ive done 100 times before back end decided to want to come out since the tires were colder :'(

lower pressure in the rear is because the rear weighs considerably less than the front of the car - requres less air pressure to keep the tire's shape.

as far as cold tires, especially if kept at higher than normal pressures for the summer - they will get unpredicatble, so please be cautious.

Back on topic - for every 10 degrees F the temperature drops, expect to loose 1 PSI of tire rpessure - so if you last checked it in the summer at 80 degrees you'll be down 6 PSI simply from the drop in temperature.

i check mine every weekend [since i work at a gas station with a shop] and set them all 5 below max press...

[95nracer]

You shouldn't have to run them at 45 something psi. 32-35 is fine for alot of people.

[MrDibbs19]

My tires are 44 max psi... so i set them at 37psi-39psi range

[95nracer]

Ah ok, I was thinking they where something like 50-51. Thanks for the clarification.

IMO
Lower tire pressures in the rear: that's most likely just to keep the general public from any potential oversteer condition. (Again, from which most of the general population would find difficult to correct in an emergency situation).
