THANK YOU!
You are likely the person I believed when deciding to replace the dead sensors. I now know to ask if the service department owns and operates a DRBII tool. I assume there is also a DRBIII as well. If they tell me they only have the Starscan then I'll know to move on. At least I won't sound totally ignorant should I decide to have these sensors relearned.

 

Sorry that was a typo I will fix. It's a DRBIII.

 

Thanks! for adding the pictures as well. I'll try to print your reply and carry it with me.

 

Glad to help.

Now the current diagnostic scanner system they use is called the wiTECH Micropod II. That application has a special enhanced emulator option for the DRBIII because that scanner is no longer supported but some dealers still have it. What I read before about the enhanced emulator program was it was only enabled by special request. The video link below from the FCA wiTECH video channel below seems to indicate it should be included but only works with an earlier version (non wireless) of the wiTECH Micropod II software.

 

I’m going to replace my front tires next week, one finally shed a steel belt. From rereading this post, it sounds like my best (cheapest) option for getting the TPMS working again is to have Discount Tire install the Schrader Universal sensor #33700, assuming that they have them. I have one year old sensors in the back tires with sensors that have never worked. Assuming that they are universal, should they be able to reset them all? Do I need them to get their codes first? Why does this have to be such a pain? 😄🤪

 

I have summer tires on my car because I store the car in an unheated garage from late fall to early spring. I have not noticed any difference after storing the summer tires in cold NH weather. What should I be looking for? Why should you not store the tires in cold weather?

 

He is talking about temperatures in the 30’s and I cannot see what the problem is at all. My tires have been stored at those temperatures for nine years and trouble free.
I would not want to drive them in those temperatures though as they lose grip in the lower temperatures.

 

From what I have learned of todays new summer tires it is okay to store most summer tires in cold temps, so long as they are warmed slowly, naturally back to above 40 before use. The rubber compounds can take the swing in temp and come back to their designed spec. How many times this can occur without some degrading I do not know. You loose performance/grip with most summer tire compounds when temps start getting below 40F.

 

At 40F they are not safe, poor grip means poor braking and spinning tires. Below 50F the tires I have start to get dodgy, the tires need to warm up and shortish trips at urban speeds do not get the job done as cold road surfaces keep the rubber temp down.

 

Total agree. I think tires made today have different compounds than those you have on your car. Your older tires may also be showing a resultant loose of performance because of the many warm cold cycles they have been through, and the accumulated mileage to the structure and tread grip. Thing is not only summer tire rubber compounds have changed over the past decade, so also has the all season. If I lived in an area with consistent temps below 45 for months during the winter and did not want to have two sets of rims/tires I would only run all season tires on the road.
Many of the top end tire manufactures "secrets" to the cutting edge compounds have been found by most manufactures. As time has passed the (some consolidation in the industry also contributes) tire compounds between manufactures has become less differentiated. Tread patterns and the internal structure is another story. Road conditions are so very important; If it is wet SLOW down and the public roads are no place to be pushing performance anyways.
