Depending on the tire, 1200 is about right.

I got a new pair of GoodYear TripleTreds for $250 off Club GP for my 17"s and they would normally have run me about $600 after shipping and all that.

BTW - those TripleTreds are friggin worth it!!! I hit an ice patch with my truck and was all over, took the car over it 15 min later just to test and they grabbed into the ice, it was like having friggin spikes on the tires!!

 

So, when you put different size rims and tires on the 06 MC doesn't it mess up the tire pressure sensor?

 

Is shouldn't bother the tire sensors any. You still need X amount of pressure in the tire no matter what. Unless you plan on purposely running them at say 20 psi?

And as long as the overall diameter of the 20s plus tires doesn't exceed the diameter of the stock wheels/tires the speedometer will be fine as well.

 

So can the transmitors be transferred from stock wheels to aftermarkets?
