Yes did a search. Learned a lot too. But, I just need confirmation that's there no TPMS sensor in the spare? Why? Replacing the spare wheel with an OEM wheel so I can do a five tire rotation and all I could gather from the topic I read is that most of you suggest that the TPMS on the 5th generation only read four TPMS signals. Also, Direct Tire wants $60 bucks to install a sensor in the replacement wheel and I didn't know if it would screw up the current system. Okay, I'm done.

NO TMPS in my 2016 SR5 ! I believe it would cost you much more than 60 bucks if you do put one on it. most likely it would not be recognized.

Thanks, I'll just tell them to skip the TPMS when they mount it then. Appreciate it.

None in the SR5, although I believe the Limited has one. I imagine they use the same system for both trims, so your system can probably handle it if you wanted it and plan to do 5 tire rotations. The system is likely set up so that the spare is not in range. Dash lights make me twitch.

Only 4 positions for tpms in the ecu edit: unless you have a newer limited.

Rotating the spare / TPMS questions? (SR5)

They must have needed the memory space for something more important...thankfully my dealer remembers to check it. I usually forget.

@OP Unfortunate, but the 4R is just not set up such that a 5 tire rotation is cost effective, unless you have the programming tool, and DIY. And, IMO $60 is not unreasonable when you factor in the cost of the TPMS, a dismount/remount, and a rebalance.

Why Toyota chose not to monitor 5 TPMS' is a mystery, and ridiculous, but ....

My LE has 5 TPMS and includes the spare.

Can someone explain to me the virtues of a 5-tire rotation? It seems like a lot of extra hassle and you don't even save any money because when it's time for a new set you have to buy 5 instead of 4.

FWIW my Limited definitely has a TPMS sensor in the spare. Some idiot at the Toyota dealership inflated my spare to 60 psi thinking it was a donut and I could see it with Techstream.

It does. The LE is actually intended to follow a 5 tire rotation. TPMS sensors feed to a transmitter which is based on physical distance. Coming from a Jeep its entirely possible to only monitor just the 4 on the hubs.

Not worth the hassle imo. I did it on the Jeep simply because the spare was exposed. Will not do it on the LE.

I do a 5-tire rotation, mostly because I can rotate them and reprogram the ECU with Techstream myself. The main benefit is that if I get a flat I can just throw the spare on and not worry about getting it fixed within a certain number of miles.

What's weird is my 08 SR5 did have one. There was plenty of times my low air light would come on and it turned out to be the spare tire. Wonder why they didn't bring it to the newer 4Rs

Because -

Basic assumptions:
1. You rotate tires every 10K miles to maximize life
2. Each tire costs $200.00 (just a number and could be + or -)
3. Cross rotate and work in spare for both directions ( I know Toyota says front to back but the math works out the same so either way is fine)
4. Tires are not uni-directional
5. You have a vehicle with a matching spare tire and rim with a TPMS.
6. Each tire has a max 50K tread life
7. You like the brand and type of tire you have and will stick with it.
8. You drive 20K miles (or more) a year.

Okay. So you have a brand new vehicle with good 50K tires, unlike the stock tires we all have (had) to begin with.

In a 4 tire rotation, you will rotate the tires 4 times and buy a new set at 50K for $800.00. You will have 4 worn out tires. Your spare will still be new and you could replace your spare with a new one and use the spare in with the new set to keep shelf life on spare optimal.

In a 5 tire rotation you will rotate tires 5 times and at 60K you will have 4 worn out tires and your original spare will have 10K miles left. Following the rules above you buy 5 new tires for a cost of $1000.00

So, if you are a 5 tire rotator (lol) you got 10K extra miles out of the set but at a cost of $200.00. You COULD keep the 10K tire for a spare and go to a future 4 tire rotation and save $200.00 but you now have an almost worn out spare that is showing some age. If you buy 5 tires and go back through the process you save no money.

The conclusion to all this is simple: Both ways are fine to use but there is no savings doing it either way. Also notice I put a spare with the same rim and TPMS under the back to make it apples to apples. If you have to either have a shop dismount and remount a tire every rotation or you purchase an additional rim with TPMS up front you are losing money. FWIW I do a 4 tire rotation. If you trade the vehicle sometime, or go to a different type or size of tire, or have to replace one due to damage then this negates any savings as well. So, the 5 tire change is no more economical as a 4 tire rotation in the long run. Sure you go 20% longer maybe but you spend 20% more. It's up to you.
