luxurycars Posted August 31, 2008 Share Posted August 31, 2008 Does anyone know the lexus recommended tire pressure for a 1997 Lexus LS400? I'm asking this as I do not have the owner's manual yet and did not see a sticker in the door jamb displaying such info. Thanks Quote Link to comment Share on other sites More sharing options...
kc92hatch Posted August 31, 2008 Share Posted August 31, 2008 Good morning, Look at the inside of the CD changer door....that's where the tire info is (of all places, eh?) Calls for between 29 and 32 psi. Good luck. Quote Link to comment Share on other sites More sharing options...
killerFatty Posted August 31, 2008 Share Posted August 31, 2008 I have mine at 32psi which is recommended for my 93 ls400 but it seems awfuly low and my tires are rated up to 40 psi should i go up to somewhere around 36 or 38? Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted August 31, 2008 Share Posted August 31, 2008 I run my tires at 38. they are 44psi max. Police cruisers run at 38 psi too ;) Quote Link to comment Share on other sites More sharing options...
Blayd Posted August 31, 2008 Share Posted August 31, 2008 Look on the tire in case the tires were ever changed to anything that differintiates from your car's recommendation. I have low profiles and the service place still set it rediculously low (for those tires) because of the vehicle's recomendation. Quote Link to comment Share on other sites More sharing options...
HRP Posted September 1, 2008 Share Posted September 1, 2008 Look on the tire in case the tires were ever changed to anything that differintiates from your car's recommendation. I have low profiles and the service place still set it rediculously low (for those tires) because of the vehicle's recomendation. Unfortunately, the car manufacturers use the tire pressure to assist in a softer ride. I run my 2002 LS430, 1991 Buick Reatta, and my 1977 Excalibur at 38 lbs. All weight well over 3700 lbs, and I like the firmer ride and better handling. The most reliable way to evaluate your pressure is to increase it to 35 - 38 lbs (cold) and then, if you like the handling, watch your tire wear. If your tires are to soft, they will wear at both edges of the tread. If they are over-inflated, they will wear in the middle (crown0 of the tread. If you'll check the wear pattern, you can determine the state of inflation. They should wear evenly. Quote Link to comment Share on other sites More sharing options...

So true tire wear is a good way of checking to see if your running the right presure that and the handling capabilities of your car also throw in if you have worn out front-end parts ie control arms top bottom ball joints shocks etc Quote Link to comment Share on other sites More sharing options...
