Not sure the Doran reports temperature, but this is an important feature for me. I love our Smartire which has worked flawlessly for three years. Not happy with the company though, because they have totally changed their design and are now selling the generation II. Since, I have the older version (generation I), the gen II sensors won't work, and they are not selling gen I sensors anymore. This means I have to buy and replace the whole system when my batteries go dead. Doesn't sound like they cared much for their pervious customers, and I won't buy another Smartire.
Doran does not report temp. You must be inside the tire to do that and any that tell you they do is not a true temp. It has a high pressure waning, which if the temp goes up so does the pressure, so it does the same thing.

This is not true. If you pick up a small leak, the pressure drops. As the pressure drops the temperature rises, thus raising the pressure. But you are still loosing air, and the tire keeps getting hotter. See how Dorian's explanation is flawed?
The ONLY way to catch this is to have temperature, and temperature compensated pressure. With SmarTire's deviation line, it will tell you how many PSI you are away for being perfect at ANY temperature. If the pressure is dropping, and the temperature is raising, when the deviation gets more than 10 psi off of where it should be, you get a warning.
We tested ALL systems on the market before we chose to use SmarTire's components with our computer system (TripTek). We had no ties to any of the companies. SmarTire simply had the best product on the market and after our extensive testing and engineering, the only product we were willing to incorporate into our product line. I use SmarTire's products every day, and part of my job is to try and break them. I have them in all my cars (4 total), my motorhome and my motorcycle. It is the best system on the market, and with the patent litigation going on, may be the only one that survives in the long run.
There is no flaw! If the pressure drops the alarm goes off. Plus Doran does it 2 ways where the others only 1. First, most if not all will go off when the pressure drop 12.5% and the Doran does that, but is also has a rapid loss alarm if to start losing like 2 lb per minute it want wait to tell you when you get to 12.5% it will give you a rapid air loss alarm. Your smartire does not do that! I don't have to wait on 10lb loss and do not want to if it is coming out fast and the Doran will let me know that.
There is NO flaw in this system, in fact NO other system has the rapid air loss alarm.
Also another problem with smartire is if you use internal tire balancing powers or liquid in your tires like a lot of people do, you can not use this system.

SmarTire gives you warnings if your tire pressure does any of the following, which are all user programmable. It does not rely on a % drop. You as the owner set the warning levels.
-Falls below the critical low pressure level. Usually set 10psi below cold inflation pressure (CIP).
-Temperature raises above the critical warning level (preset at 194 degrees, but can be changed by the user).
-Deviates more than 10psi from where the pressure should be for any temperature and driving condition.
A bit of an explanation on deviation and temperature compensated pressure, a SmarTire exclusive. If you have a tire that is set at 100psi cold, cold means at 65 degrees F. If the temperature is 90 degrees outside and you fill to 100psi, you are actually already low.
Now, take that tire and as you roll down the highway, the temperature rises, as does the pressure. On an average 85 degree day, at highway speeds, seeing temperatures in the 150 degrees range is normal. Your 100psi tire should now be running at about 118 psi. With any other pressure only system, how do you know if 118 psi is correct, or are you off? The SmarTire system knows what the pressure should be given the CIP, and the current temperature of the tire. It will let you know how far from the perfect pressure you are at. And if you deviate more than 10psi from perfect the alarm will sound, even if it is above the CIP.
Internal balancing products have no negative affect on SmarTire transmitters. None of those products will void the warranty. I have even tested them with liquid "fix a flat" type products and a liquid balancing product called "ride on" and neither had any problem.
Battery life is realistically in the 10+ year range for RV tires.
Well the Doran 360 rv just came out a couple of months ago, so you have not tested them all. try it, you might find it superior.
If it does not offer temperature, it can not compare. That is critical. There is no way to offer the protection that SmarTire offers without accurate temperature readings. And that is from me as an engineer, not just a user.
Besides, SmarTire just won another huge battle in the patent wars against Schrader. This is the second win out of two lawsuits. Doran and Pressure-Pro are next in line. SmarTire owns all the patents for the technology and Doran as well as others are blatantly violating them. They will either have to pay up or go under.
Totally agree! I just wish SmarTire didn't make my SmarTire generation 1 system obsolete when they brought in their new generation II system. I can't get replacement sensors for my unit. When this goes kaput, I have to buy another system.

I've got SmarTire also. 23,000 miles and running without issue. The air pressure and temperatures are displaced on one of my two in dash monitors via TripTek. The internal temperatures are great to know as I found using my infrared thermometer tends to show only skin temp which is adversely affected by the sun shining on them.
We just had the Smart Tire installed last week on our MH and toad.
This weekend was our first trip out and we got a deviation warning on the toad after about 5 miles on the road.
We stopped and checked the tire and it "looked" fine, so we assumed that Camping world set something wrong....Well, when we got to our camping spot, we found a nail in the tire.
It is fixed now and all I can say is Way To Go SmartTire!
I am a firm believer that any type of sensor is better than none,I just feel safer with this one.
