how many pounds of air do you guys normally try to maintain your tiers at, all these people tell me to have 45 lbs and i think its crazy, i try to keep it at 35lbs but they insist that low profile tires need around 45lbs, so any help would do.

 

35 should be fine for the stock RE92 tires. I don't remember what their maximum pressure is; for that check the sidewall. My S-03's I believe allow a maximum of 52psi.. it is up to the driver to decide how high/low they want it; don't forget your tire pressure drops in teh cold, and remember that higher pressure = better treadwear, stiffer ride, and less sidewall flex (better grip in the twisties - IF you have a good tire which the RE92 certainly isn't so don't push it). Lower pressure = more treadwear, better grip in the straightline due to additional flex in the sidewall, and a softer ride. Also making pressure vary from front to rear can generate some oversteer or understeer. You can go by manufacturer spec which is labeled in the car, or you can go based on people's suggestions - which is a matter of personal preference more than anything else.

As long as you're not running something ridiculously stupid like 22psi you'll be fine. If you were running that low, you'd probably lose a tire pretty quickly

 

Do not go as high as that (unless the tire CLEARLY has a much higher max pressure limit). If you start with a cold pressure of that, once the tire heats up it could become dangerously overpressured.

 

I keep all four at 34psi.

 

The recommended inflation pressure is listed as 32. You can find it under the lid of the armrest.

When at the track I go as high as 42 without any problems (on the rear).

 

good ride, no issues. Remember, 62 % of our car's weight is on the front wheels, no need to run same pressure....indeed, lower in the rear balances handling a bit

 

 

So the 3-psi diference in pressure in the front tire is to balance the rear for handling purposes?

Just a thought here:
Since 62% of the weight is in front. The different in percentage ratio is 12% (62%-50%) in order to balance out the weight distribution w/pressure...would a 34-front/30-rear be more ideal?

 

 

added weight better -less sidewall deformation, less chance to damage a rim due to untowards sidewall deformation on a sharp impact- as well as provide more equal overall tire behavior in the more heavily-loaded fronts versus the less loaded rears.

Put another way, the increased weight in the front versus the rear -along with the lower roll center and higher roll resistance (sway bar) in the front suspension versus the rear suspension- will ALWAYS create a greater load (hence deflection) in the fronts more than the rears..., the higher pressure compensates that somewhat.

 

I keep 32 lbs in all four tires.

 

On the RE92's just don't go too far over 32 on the fronts. It causes them to unfortunately spin out easier.

Especially if you are a gas pedal liberal.
