Adding air to Land Cruiser spare tire...

[Paul19876]

Just purchased a 2018 LC and I'm wondering if there's any way to add air to the spare without having to drop the spare tire to the ground. I need to do this to prevent the TPMS dash light from coming on.

Thank you.

if You crawl under there you should see the valve stem and be able to access it

No hack for this that I am aware, at least on my 2013. Just have to drop it down and fill it up. 5 min job at most.

Have to drop it to access the valve stem. It’s the same on my 200 and my pickup.

Look at as practice using your spare tire tools in the event you do get a flat. You’ll be that much more proficient with the process.

I just lay underneath, locate the stem and fill it. I’ve never dropped it before

If you're doing a 5-tire rotation it's pretty much a non-issue; it gets replaced with an aired up tire every 4 or five months.

There are extension hoses available that stay attached to the spare, but for me, it is pretty easy to drop the spare. Here is what one looks like:

I could get to it just fine before I got my swing out. Now I can get to it even easier!

I have had good luck with using the inside of of a chuck like the one pictured. I reach through the ‘spokes’ and pull down on the chuck.

I would add that annually or 18 mos it’s a decent idea to exercise the mechanism because especially in ‘road salt climates’ corrosion can make the winches sticky. Pro-tip: Make a slight mark on the tire to help you line-up the valve stem is at the rear of the vehicle which allows you to slide under less to service it.

Thanks guys. Some creative ideas for sure.

Thank you.

So are you being proactive, or is your TPMS light coming on? If the latter, you have a leak in the tire, stem, or rim seal. It takes a VERY long time for enough air to naturally leak out of a spare to fire off the TPMS. If the former, don't worry about it. As noted above, you should exercise the mechanism at least once a year to make sure it works when you need it. I've had to cut the chain on a Toyota and 2 Hondas due to locked up mechanisms from corrosion.

Sandroad, I am just being proactive, just like I'm planning on spraying LPS3 on the KDSS valve this weekend.

I added air to my spare this weekend. Is it a good idea to hit the mechanism with some wd40 or silicone spray while the spare is down?

It cannot hurt. I’d choose a drier lube that won’t attract and hold dirt. Any light spray vs heavy oily stuff

I did a similar thing using the Boeshield product. After it dried I followed up with a coating of Yamalube marine grease. Just checked it the other day and all is well (almost 3 years in). Not sure which product helped most.
