Re: Spare tyre mounting options
You can purchase a flexible braided hose which screws onto the tyre valve on the spare and allows you to have a "remote" valve. I have one on my Territory, where the spare is under the car. I ran the hose and attached it to the towbar, so I simply need to check the tyre pressure there, rather than lowering the tyre from it's cradle. Easy Peasy.
I also have a TPMS system on a computer in the car, and that monitors all 5 tyres. Gives Pressure and Temp in each tyre. It would be interesting to know whether the Jeep system can be configured for the spare tyre. If it could, all you would need to do is install a TPMS valve in the spare, and have the dealer program the dash to recognise it.
