I got new wheels for my summer tires for the Preferred Plus. Discount Tire mounted them but didn't have any TPMS sensor's for the CX-50 so they pulled the ones from the OEM wheels and mounted those instead. They programmed the sensors and off I went. After about 5 minutes of driving two of the wheels were correctly identified and picked up by the TPMS system, two wheels did not. So after sitting overnight, and driving it again for 30 minutes at 50 MPH+ the sensors are still not recognized.

Went back to Discount Tire and asked them to re-program them and they said they didn't have the correct programming in their system for the CX-50 and that I would have to go to Mazda to have them programmed. The local dealership indicated an hour service appointment and $85 charge.

I see from some of the posts that people have new wheels put on. Can anyone speak to their luck with getting the TPMS sensors re-programmed?

thanks,

I had my tires changed at a local tire shop. They told me the same thing that they don’t have the TPMS because the model is so new. At first the car did have tire pressure warning but it’s gone after 10 mins.

Switched out my Goodyears for Michelins at Costco…as far as I know, no problem. I get accurate tire
pressure readings for all four tires on the My Mazda app—they read lower after cooling off overnight, then a bit higher after a drive.

Lucky! I'm thinking about doing the same thing. Please update us on the improvement. As we all know, always check tire pressure before driving, when cold in the morning and adjust pressure accordingly. I have a good Akface tire pressure pump that you plug into the accessory socket to increase pressure when needed. The Akface pump fits nicely in the spare tire location in the trunk. I have always been a real stickler for correct tire pressure since it makes such an impact on tire wear and overall "drive-ability". (and always rotate tires) I really hated my Audi, because it did not display actual tire pressure on all wheels. Only provided a warning if tire pressure was low. I have always driven on Michelin's, and love that tire and still loving my 50. Bought on 4-22-22 and have almost 6K on the odometer.

Thanks JeffC

Stopped off at the local Mazda dealership to ask them about the TPMS. They said I can make an appointment to have the TPMS sensors registration performed to the tune of about $85 US. They did tell me that the sensors and system in the CX-50 is identical to the CX-30 and that the sensors, tool, and procedure for registering the TPMS is the same between the CX-30 and the CX-50. Back over at Discount Tire, they tried to read the sensors with their scan tool. They were able to read one of the sensors ( which apparently registered a low battery condition) but couldn't read the other sensors. Manager at Discount Tire was going to do some investigation and checking with their experts. They did offer to reimburse me the $85 dollars I would have to pay to the Mazda Dealership if they are not able to figure out the TPMS registration, assuming the sensors and not found to be defective. These are the same sensors that were in the OEM tires and merely moved to the new wheels/tires.

Interesting. Thanks for the heads up!

Hi, Random Question What size wheels did you get to replace the stocks? We just purchased a non turbo version with the 17 in rims and i'm already itching to replace them. I know that the turbo comes with 20 x 8, but there isnt any information in relation to the offset.

thanks,
Steven

Oem offset should be +45. The wheels I put on are 19 x 8.5 +35 offset. Tires are Continental 255 40 R19 just because they were on the second hand rims I found. The tires are a little smaller than OEM so the speedo is off a bit.

To continue, I brought the car into my local dealership. It took them an hour and a half to program the sensors and they said they had to go beyond their normal process of using a programming tool. Drove away and within a mile the error on the display returned. I drove for 20 minutes on the freeway but it still didn't clear. Looks like I will be spending another afternoon at the dealership.

Anyone who is following this, here is my final wrap up. Left the car at the dealership all day since I had a ride home. They removed the tires and found all 4 sensors damaged. They had parts in stock and so replaced all 4 sensors, re-mounted tires, re- balanced, and programmed the new sensors (not sure if the sensors actually came programmed as they are OEM, but they were at least discovered by driving the car at highway speed). All good on this end. Then it was off to Discount Tire. The manager I had been working with was fantastic and filed a " claim" with the corporate office for my full cost at the dealership, no haggling or trying to blame someone else. They said they would send a check from corporate office, so assume that was taken care of unless I report back.

As for me, $600 for used wheels and tires iff of Craigslist+ $80 for mounting/balance/ original tpms swapout. I will get a good chunk of that back by having two sets of tires that last twice as long as a single set.
