Alright guys and gals,

I'm about to pull the trigger on wheels from AM. Two questions! First, what all do I need to purchase to make sure the TPMS light doesn't come on. I want everything to work like how it is right now stock. Secondly, is it true that if you get a different size wheel, your speedo will be off? I currently have 19'" premium wheels and I am going to purchase some 20" wheels. Will I be fine?

 

the speedo will be off if the overall diameter of the tire changes.
say you have 26 inch diameter and goto a 25in or something, the revolutions per mile will be different

I would assume you would need to include the TPMS kit and syncing tool etc

 

Damn, all that just for some wheels! Thanks!

 

Well there is the method of putting the tpms from stock tires in a pvc pipe and tossing it in the trunk, but then that takes the entire use of them out. or just deal with the light, whatever you want

 

Here is a good website for tire size and what it does to your speedo. Plug in your stock tire size and then what you will be buying and it will tell you the differences.

I dont see anything in your post about tires, so if you're not having the tires mounted by AM and shipped, you could consider reusing the tpms sensors in your existing wheels.

 

Buy the stem TPMS sensors and stop by a Discount Tire and have them sync it for you. I did this and it worked like a charm, plus I think the valve stem TPMS are better then the bands.

 

^ Couldn't agree more

 

check e-bay...I bought a set (4) of new OEM sensors, cradles and rings for just $160.
