Can someone tell me the order of the tire pressure display? I'm assuming the spare is the first one listed as that seems to have the highest pressure. I wish checking tire pressures were as easy on my Lexus as they are on my GM products.

 

Yes it can be unclear which one is which, there was a thread discussing it here:

and unfortunately there is no specific ordering

 

Wow! After reading the info. on the link provided by encore888, I think I'll just continue to use my tire gauge. From now on, I'll only refer to the TPMS readings if I get a low pressure warning. I thought things were supposed to be simple and user friendly on a Lexus

 

lol, at least you know what pressures are in the wheels. on some other lexus, you only get the msg saying if you have a low or not, don't even know what pressure

 

On mine the top one seems to be the spare, since it hardly ever fluctuates.
The other 4 change as the car is driven, but there is no order to it from what I can tell.
I suppose one could do a home experiment to determine which is which, but it wont be the same for all cars that's for sure.

 

and after one tire rotation it's all changed (except spare). or if you get a flat and changed, it's all different too

 

And I can't resist saying again that it's a shame Lexus doesn't use the current tech employed by others. I've owned several cars that displayed the tire pressure BY TIRE, and clearly showed which was which.






Like the voice recognition and some other tech, Lexus oddly sticks with yesterday's stuff.

Mine is definitely spare first with unknown (but surely in use) tire positions thereafter. I stay at 32 on the first spot and hit all the way up to 36 on the remainder when on the hwy.

 

hahhaa mike, that's how lexus can say they improve when the new car comes out
