Does the 2015 Cornerstone come with a Tire pressure monitoring system. I thought it did, but cant seep to get mine to activate.

No from what I researched it does not. The american coaches do , but they have no (virtually) basement storage. The american coaches have screw on valve stem sensors so it should be an easy add on.

Trip tek offers it as a option it cost $1500 so i went with tire minder. I am happy with it, the hardest part was were to put booster. $700

In 2013 I reviewed a Cornerstone that did have the TPMS from TireSentry. I had one of those once and it was a good system but they are no more so it disappeared from the Cornerstone. There are a number of decent TPMS systems out there that meet an RV owner's needs. They are all a bit different so everyone seems to have their own preferences. I prefer an internal sensor system that monitors temperatures as well as pressures such as SmarTire, which was bought out by Bendix a few years ago and converted over to 18 wheeler use. They no longer support RV applications but fortunately I retained my SmarTire system from our last coach and installed that in our Cornerstone. Had that not been possible I would most likely have gone with an internal system from TST.

It may be just me but personally I don't care for the systems like TripTek that use the monitor screen to display information. I prefer to keep my monitor clean so that I can see the rear camera without all that clutter.

I have a '15 Cornerstone and mine does not have a TPMS.

TST has both internal and several kinds of external sensors. I bought the TST 507 unit for our Dutch Star and used both the cap and flow through sensors.
The Magna came with the Smartire system,

I agree with Cruzer on using the monitor, I like a separate one for my tire monitoring. I have a Pressure Pro system that I have had for several years. It has a separate monitor and works well if all you want is tire pressure with low and high pressure alerts. It is simple, sensors merely screw on to valve stems and transmit wirelessly. I have 12 sensors so toad is also covered. I have a repeater you can mount in the back of the coach to boost signals but have not installed it in the last two coaches as I have not needed it. Some of the newer units also have temp sensors and read outs which might be nice but I have not felt the need for them. My system is now 7 years old and I recently replaced two sensors because of dead batteries, otherwise no maintenance and they work great.

I have Tire Minder TPMS and like it most of the time. It does not have pass through external sensors and the sensors/transmitters are like plastic caps on the end of the valve stems. System has replaceable button batteries in transmitters. Have had problems with rubber o-rings between screw-on caps and some plastic caps themselves will crack due to pressure against sensor, but Tire Minder has been willing to provide free batteries and o-rings and caps when my fracture. Also, have had a couple of transmitters go out too, and they have swapped the bad sensors with new good sensors gratis. Monitor displays both tire pressure and temperature, and picks up all tires on coach and toad without the repeater. Available on Amazon and EBay in addition to RV sales places.

I had one experience where my tire temperature monitoring paid off for me. We had just left Custer State Park one morning on the way towards the Yellowstone area. After arriving in Custer, SD, which was about a 30 minute drive, my Smartire system went off. I pulled over into a parking lot and toggled the display to see what was up. It turned out that the rear Jeep tires had trigger a high temperature alert and both were extremely hot. Toggling through the rest of the tire temps I found that the coach was fine but the front Jeep tires were approaching the temperature threshold as well. I went outside to check it out and found that the air solenoid that control the breakaway feature on the Jeep's M&G braking system had failed and was bleeding air through, causing the Jeep brakes to drag. I corrected the problem and cooled the hot Jeep rims down with water from the coach and we were on our way again.

Had I not had the ability to monitor the tire temperatures I would have lost the Jeep's brakes and most likely overheated the tires, brake fluid, and everything else. Oftentimes this results in a fire. Since then I have determined to always have a TPMS that monitors temperatures as well as pressures.

I have tried a couple different brands of external TPMS systems with not so great satisfaction until our current system, EZEERV TPMS that gives both pressure and temp readings. I found the system very easy to program and like the fact that you can turn it on and in about 5 minutes or less get your readings before heading out. We will be moving this TPMS from our Allegro Bus to our Anthem when we take delivery in October.

I have used my TIRE MIMDER on my 14 Anthem RBQ & my 15 cornerstone !!45B!!. With that said I had a problem. the inside tire has a extension. I tighten the caps my hand but so tight that the "o" ring was pushed into the valve core & blocked the air. Could not get a reading had to have tires removed , they installed new extension w/ new "o" ring. The TIRE MINDER has both TEMP & PRESSURE.

I had the same problem on my 14 Anthem with the inner dual tire extensions on my TST system. I contacted TST to ask about a recommended tire extension and Dan, the owner said he couldn't recommend any so I removed the extensions. Other than being difficult to tighten the set screws my system works great without the extensions.

I've also had to replace those extensions on the inner duals when they stopped passing air to my TPMS sensors. Found replacements at a truck stop that are working OK so far.

At my first opportunity to have the duals off, I will install a set of "Dually Valves" found here on the inners. I put a set on my Monaco along with the rubber plugs that fit in the hole in the outer wheel that stabilizes them, and they worked well. Eliminates one source of leaks.
