I have my 2008 H3 floating on jack stands waiting for her newly powder-coated wheels and 33" Hankook Dyna Pro MTs. Since I think it would be a good idea to include the spare in the tire rotation, with these being heavy lug tires, I want to add a sensor to the spare. Will this work if I follow the proper calibration set up? I'm assuming that because the earlier years did come with sensors in the spare that it will work. Are there any tire rotation secrets for MTs?

 

your spare should have the sensor in them already...I'm not aware that the 08's came without them. Are you sure you don't have one in the spare?

 

None at all...rubber valve stem....I read somewhere they stopped putting them in the spare for the 08s...

 

no chit...that's strange that they would stop using them in the spares. Does your manual still recommend that you put the spare into your tire rotation?

 

The manual doesn't show the spare in the rotation...GM's way of saving a few bucks maybe...I like the idea of rotating the spare in..that way when I'm due a new set of tires I can get something different and don't have to match the spare...who knows what cool tire might be just a couple years out!

 

I just picked up an 08, and they told me when I picked it up that the spare doesn't have the sensor anymore. I don't understand that logic.

I would say do it.

 

How much could GM really be saving? What a load of crap, my dealer wouldn't put my spare into the rotation unless I bought an allignment. Is he just trying to sell me more stuff, if I rotate the tires every 5,000 miles do you have to get an allignment each time?

 

Your dealer is screwing with you. I have rotated my spares in on any number of vehicles and never had to do an alignment.

 

yea trey...he's trying to pull one on you. An alignment is based on the geometry of your suspension, not what tire you have on the axle.

 

My guess would be the dealers were getting complaints from customers who put the spare in the rotation or had a flat and that the DIC was indicating a problem with the sensor because they did not go through the resetting procedure. I have had sensors on my two vettes for years (factory) and it's not difficult to reset them but not something a lot of folks would know how or want to do.
