I ran into an interesting problem. I just swapped out my rims and tires for newer Cherokee rims and 10 ply Goodyear Wrangler tires. The problem is that the 10 plies run at 80 psi. At first the system just showed maximum pressure, which is what I thought it would do. Today the tire warning symbol kept flashing and I received a message that the system required servicing. Can it be reprogrammed or shut off?

I would love to KILL my TPMS as well in the worst way. Saw an after-market plug in play sender unit that sends out 4 tire signals of 35psi on Youtube. I may go this route if others do not have better ideas. good luck

I need to replace 2 sensors if I don't go with that other unit that sends 4 fake signals.
1. Are most sensors made the same and any after market will do? Mhz? If not do u only recommend Mopar?
2. Can any tire place program for a few bucks cause ain't NO WAY I'm going to Jeep?
3. Is it worth buying the equip to program myself?

OEM sensors are available on Ebay for a song so I wouldn't take a chance on aftermarket.

Do you have a link for the signal faking unit?

I just started looking for a reprogrammer and haven't found anything yet.

Some of the equipment needed is expensive,. If it is StarScan, they are over $1000.

Generally, you want to run tires at a pressure for your vehicle rather than the maximum pressure for the tire. The reason 10 ply tires are rated at 80 PSI is that they're designed to handle a lot of weight. With the weight on, the tires will wear evenly at 80 PSI. However, with less weight, like your XK, you're running them overinflated and will end up wearing the center of the tire far more quickly than the edges.

One good way to set the PSI for your specific application is to use sidewalk chalk. Run the tire over the chalk and deflate/inflate until the footprint of the tire is even across the entire tread. This will probably be close to the 35 PSI recommended by Jeep.

Consumed, I spoke to a high end rim and tire shop and he told me to run them at 45-50 psi. I had the last set that were on my commander rims at 45 psi , their max rated pressure, without issue. I set these to the same pressure but the system is still messed up telling me that one the tires is below pressure. I think that it's due to the fact that the sensors the new rims need to be programmed into the ecm.
