Dont have the owners manual, the tire says 44psi is maximum, what do you recommend.
Thanks for the help

 

30-32 psi ought to be about right for your LS unless you do serious speed for extended periods, in which case I'd suggest going 36-38. Or unless you haul a serious lot of heavy junk (or heavy relatives).

Ought to check with your dealer or look on ebay. Should be able to find owner's manual; lots of good info there beyond tire pressures.

 

Mooretorque's recommendation is probably correct, as usual.

Also, there should be an info plate on your inner driver's door or glove compartment door with Lexus guidelines. If not you can e-mail or call Lexus customer service for the info (go to www.lexus.com for the contact info).

 

doh!!!! and marty has again reminded me of the obvious, which in my less-than-infinite wisdom, i admit i had forgotten totally about. and me, a former gas pump jockey. too many fumes, i guess.......or could it have been all that other..............never mind.
