I changed the oil in my wife's Lexus ES350 a couple of days ago (first time for me), and she asked me to check her tire pressures...the TPMS was showing two tires to be low. When I got around to checking, none were less than 30 psi, and the tire sticker and manual both call for 33, so I filled all to 34 and called it good. Then I went to check the tires on the X.

It's been awhile since I did, getting side-tracked by other projects with the X lately, and I'm ashamed to admit that all four tires were 5-6 psi low. So, I filled the fronts to 34 psi (with cooler weather approaching, I always go a coupla psi extra, to make up for it), and the rears to 41 psi (same reason). Then, I emptied the trunk of all 3-400 lbs of tools, spare parts, and miscellanous gear, so I could lift the cover off of the spare, to add extenders.

When I replaced the battery recently, I checked the tire pressure in the spare, and found it to be at 25 psi. I probably haven't checked it for two years or more, since it's a real chore to empty the trunk and put it all back in some sort of order. Today, the pair of extenders was added, along with two right-angle metal fittings, with the access point at the right rear corner of the trunk, so now I can easily check the spare with gear and cover intact. One of the fittings pokes up between the cover and trunk floor, so I'll not have to empty the trunk after this, just to check the spare.
rubber hoses link together, right-angle fittings on opposite ends
