TPMS Sensors

If I replace tires and wheels with 315 mhz sensors with different tires and wheels with 315 mhz sensors, do I need to clone the new ones to the old ones or does the 315 mhz do that automatically?

 

315 MHz doesn't automatically make them compatible in the first place. Nothing will happen automatically. You either clone the new sensors to the previous id's (if they're cloneable) or program the id's of the new, system compatible sensors into the truck's tpms system.

 

^^^ What he said is spot on.

 

The reason I asked about compatibility was I changed the tires and wheels earlier this week and have driven the truck about 100 miles and the TPMS light on the dash has NOT come on yet.Now I have something to look forward to. Thanks for the answer.

 

This is odd but I'm going to take a good guess and say you are not seeing tires pressures on the dash and you have not driven over 22 minutes in a single trip yet.

I started getting tpms issues after getting new tires over a year ago so I'm sure they messed one up. It was intermittent at first then ok for months now I get the light right away. I bought a Autel TS508 to figure things out.

No pressure reading but no light means the truck is reading the sensors but can't figure out the locations. After approximately 22 minutes the light starts flashing then goes solid.

No pressure readings and the light coming on right away is at least one sensor is bad which is where I'm finally at now.

Like said before you need someone to enter your current sensor IDs into the truck. The TS508 can do that if you wish to go that way.
