We got rid of our run flats and bought new tires recommended here. We have a 2003 SC430 and the tires say max pressure 51lbs... It's been a while for us so we are not sure what level to fill them at. Do we do the recommended max? Or is there a better option? We used to live in New England and we now reside in Atlanta so we didn't know if the climate difference would be a factor.
View 8 RepliesI bought a new IS 250 F-sport 2 weeks ago and the tire indicator drives me crazy. The low tire pressure light on twice in a week. I added up to 36pis (Recommended Pressure) and all tires went down after a few days. I went back to Lexus today for tire pressure. Every tire is okay but tire pressure is low only. Btw, my gas indicator did not rise up after I filled gas. The indicator started to rise up after I drove about 2 miles. Is that normal for a new car?
View 11 RepliesWhat is the maximum safe tire pressure with 19" wheels? I don't mean cold pressure. I mean maximum pressure. My rears showed 50psi on the TPMS after 20 min of driving. When I got home and measured them, they were 50.5/50psi. It's been roughly 110 degrees over the past week. It is impossible to get a true cold tire reading because it doesn't go below 85 degrees these days. So... am I well inside a safe zone at 50?
View 15 RepliesMy tire pressure light has come on - it did once before about 8 months ago. All tire (not flatruns) pressures seem fine (between 34-38 not cold). Tires were rotated by dealer not too long ago. Do I need to reset the pressure light - understand it is somewhere under driver side dash? Previously I think I added air and light went off. But this time tires don't need air.

View 10 RepliesMy 2002 SC430 is driven 2 -3 times week and has 30K on it. January '08 I replaced run-flats with high-end non-RF Michelins sugg'd here. Ever since, tires have lost pressure. So far, I was told front pass. rim (orig. factory chrome) had a crack, that was fixed, but tire still loses pressure. Rear Driver's tire supposedly punctured at 2 weeks & replaced..but still loses pressure. All tires & wheels were checked & rotated, now 2 still leak in new positions.
According to Dealership & Tire place familiar with SC430's, my Valve stems and sensors are fine (TPMS works fine), tires are good, rims aren't cracked, but tires go soft. Yesterday a Tire place that does only Lexus & Toyota just told me "invisible corrosion" on rims makes moisture collect where tires seal to rims and this causes slow leak!?
I was wondering what the maximum size tire with no lifts or leveling I could put on my truck would be. I was looking at a pair of Nitto grapler g2's at 295/70r17 with my stock wheels. Would that fit?
View 3 RepliesI need to check the fuel pressure to verify if my fuel pump is functioning. What is the procedure and PSI?
Assume that I open the valve on fuel rail with engine off, then connect pressure tester kit, put key in ignition to "on" position, then pump up to specified PSI???
I want to disconnect a wire to turn off the tire warning light. I've heard several wire options behind the glove compartment but it's confusing. Any easier clearer answer as to which wire is the right one?
View 14 RepliesWorking on my car after getting it back from bad mechanic. The jerk didn't correctly reconnect the AC lines and now it's not holding pressure. The leak is right on the firewall, with one big and one small line. When I disconnect the lines I tried to reconnect using an o-ring gasket but it's still not holding pressure. Probably need OE o-rings, but I did this last summer and got it to hold pressure fine.
View 11 RepliesTake a look at the video I recorded with my phone and you can hear a thumping or clunking noise coming from the rear driver side tire. The phone was held upside down sorry!. I'm thinking it's either the brake pads or wheel bearing?
Please try to ignore the wind noises. = Just want some idea so when I take it to a mechanic it would be easier to identify the problem. [URL] ....
Any way I can set up the tire pressure warning to come on at 27psi or so? I want to set the tires at 30psi for a more comfy ride and not have the warning light on. Don't care about mileage. Want the cushy Lexus ride.
View 14 RepliesSo this morning heading to work the low tire pressure notification popped up. I filled my tires with air afterwards, but the light and notification are still present. Would that reset on it's own, or do I have to do something along the lines of when resetting the oil maintenance message thru the speedometer settings?
View 11 Repliesjust noticed a discrepancy between the door sticker and TPMS readings; 36PSI for the door sticker and 47PSI on the TPMS. A long story short, measured with a gauge and the TPMS readings are accurate sent a message to my dealer because I took delivery of the car 10 days ago, no answer. I understand those tires are filled with Nitrogen, are the original values (47PSI) a requirement for Nitrogen or should I deflate those tires to door stickers values ?

The tire pressure light just came on in a 5 year old tire that I decided to put on the ES350.
The two front tires are 36 lbs, two rear were 32, I adjusted them all to be around 32 and the light is still on, including the spare tire in the trunk.
I decided to put this tire on because it has much better tread than the last. Regardless, I don't know why the light is on.
My TPM light went on coming into work this morning. I did a visual check, everything looked ok. When I got to work got out the old gauge and they all show about 28 psi. The manual states it can go on due to 'natural causes' but doesn't really go into detail. Will it goes on if any/all tires fall below a certain psi? I'll be going back out later to check again to see if one of the tires is going flat.
View 10 RepliesI bought a 2011 GX 460 premium, i have the car for 5 months now. I checked the tire pressure earlier and all tire pressure are low, i was wondering how come the tire pressure light did not light up. How to set up/ steps in adjusting tire pressure monitoring system. I searched on the manual, I can't find the steps.
View 9 RepliesThe tire pressure reset button? I don't see this button vs. where the owners manual says it is. Can any post a pic of where this button is?
