Full size spare is not balanced so beware.....

At first thought, I’m thinking it’s a good idea to rotate the spare in...

1. Prolonged tread wear by some percentage... is it 5% or 20%?

2. Keep tabs on the condition of the spare.

But maybe some negatives as well...

1. Cost... additional sensor, sensor installation, tire balance to get started, then need to purchase a 5th tire when new tires are needed, mount and balance 5th tire.

2. Additional time/work when rotating.

I don’t know...

To me, the benefits of 1 and 2 outweighed the downside of the 1x cost for a sensor, sensor mount and ?balance, and the added time of the rotation.. There is the added cost of a 5th tire when you buy a new set, but you gain:
-a matching tire (assuming you change from the KO2's when you replace the tires)
-a fresher spare (opposed to a 1-?? year old spare) to get you out of a bind, and you can have full confidence in it
-depending on how long a set of tires lasts you, you probably should replace the spare with every other set anyway (just my opinion), so why not get some use (mileage) out of it and prolong the need to buy new sets a bit?
-if there ARE issues with it (balance, sidewall bulge, slow leak) you'll identify them that much sooner to get it taken care of.

As related to the OEM installed tires only; at what mileage intervals would you suggest to do the following:

1) Rotate main tires, leaving the spare in place only for emergency?

2) Rotate main tires using the spare as part of your rotation?

Myth confirmed Jamie.

I noticed after last service 2 out of 4 tires showed “--“ on the PSI. S/A insisted - no problem. drive it an within a couple minutes the truck will pick it up. It worked.

I'm not having that luck. Installed my new wheels Saturday and after going back and forth to work this week, I'm at 125 miles and still no re-learn. Guess I'll try the owner's manual method or buy that TPMS tool. Gen 2 btw.

interesting. there’s probably a rhyme or reason to it. try the manual method.

Ordered new TPMS sensor for the spare

And

$26 for the reset tool
$17 for the TPMS sensor.

Mount and balance should cost me $25

If it gives me 6 months extra time to delay spending $1500 on tires....4 or 5....I am all for it. If you don't use your spare.....and your tires last 3 years (long shot)...what kind of condition is the tire going to be in that was mounted and not used for 3 years.

Can you buy 4 - tires that match your 3 year old spare?

I think I agree with the general idea... but I would just like to quantify the cost of process. Not that I need some elaborate cost/benefit analysis, but I want to be able to say... yeah that's worth it.

Sensor ~$50, Sensor Install and Balance ~$25... So about $75 to get the process started.

Tire ~$275, Mount and Balance ~$25... So about $300 more each new set of tires.

So for at least $375 (assuming you own the truck through at least the first set of tires) you get some percentage of prolonged tire wear, and peace of mind regarding the spare.

Lets assume a maximum 20% increase in tire wear on 40,000 miles... which is an additional 8000 miles or 6 months for most DDs (or ~every 3 years vs 2.5 years).

So... having said all that...another benefit could be if you sell or trade in the 1st 2-3 years, you may not have to put a new set of tires on in that time for your $75 initial investment!

Has anyone just tried going to the dealership and complaining about it to see if they will put the sensor and balance the wheel for free...... Just a thought.

I just sold a 2001 Honda Accord after 17 years, to buy my Raptor.

It only saw the dealer one time, for that airbag recall. 6 months after the dealer touched the car, the airbag computer went bad, throwing lights on the dash. The Honda dealer wanted $1,600 to repair it. I found a used computer for $24 in a junkyard, and it worked.

I never ever go back to any dealership.

Splitting hairs here...but the sensor was $17
