What tire pressure do you run on the street? If you respond please toss in what model/size rubber your run.

I have a stock sized set of Nitto Invos on right now, they're reaching the end of their service life soon. I had them on the rack the other day and one of the tech's pointed out that they looked 'bulged' around the belts. He thought it could be from over inflation. I thought that was doubtfull seeing as I've never inflated them above 40psi and they max out at 51.

How do you like those tires overall? I was thinking about getting them in the spring. (Blizzaks are going back on in a few monthe )

How would you rate them from a daily driving standpoint. I've heard they're solid crossover for AutoX.

Yokahama S-drive 255/18/35 - 36psi

I've ran them down to 32psi for an auto-x and that was about the tire pressure limit for side loading, the tire was rolling over.

Kumho Ecsta XS 245/45-17. 38 psi cold for street driving and around 35psi hot for track/time attack

I'm not quite certain what that means.. if I'm guessing you're referring to the info on the door jam sticker?

YES for the street.......I have had three sets and would never go back to anything less. ....I keep them on 365 days of the year, including driving in the winter here in North Georgia. Did not seem to affect the rubber the following spring.

Great in rain as well. Pair them with decent pads for a real eye opener :-)

They will not hold the road well below 32F, my only real disclaimer. Then again you will be taking them off up North for the Blizzaks

NewEnglandRT

Yeah, I'll definately be spending at least a few days below that temp... hopefully not that many!

My standby are Hawk HPS pads, what do you prefer?

It's probably in a thread somewhere else but a few of you replied that you run less pressure for autoX.

I seem to recal reading that you should go up in pressure to lower the amount of deflection in the tire..... it's been a while though.

If I am driving on the street I will run 34 cold front and 32 cold rear. If I am auto-xing I will run 35 cold all around. When I auto-x I check the tire pressure after each run. I make sure I keep it at a consistent 35 psi on each tire and bleed off extra air when hot.

It really depends on what you are trying to accomplish. There is a medium.

High tire pressure will start to make the tire buldge, which will reduce its grip.
Low tire pressure will make the tire roll over and make it spongy on cornering... for example, sometimes you'll see ppl mark the sidewall of there tire. This will allow you to see how the tire is rolling, you shouldn't be wearing your sidewalls
