After noting that the TST tire pressure system has had good reviews on this forum I ordered a set. Today was to be "learn about the system and set up the sensors" day. Did not go well. Upon trying to fit the first sensor to the right front wheel valve I find there is not enough room in the wheel opening for the sensor to fit. These are Accuride wheels with rather narrow triangular openings. Same situation on the outside duals. The sensors will fit on the inside duals. The most obvious fix would be to use short valve extenders. However, I am somewhat concerned about the front wheel sensors extending beyond the wheel surface and possibly getting damaged from road debris. Also, the outside dual installation would have to be done by reaching between the duals and I haven't gotten far enough to even see if that is feasable. Has anyone else run into this problem and, if so, what was your fix. Yes, I know there are other systems out there that might work but let's stick to this problem first.
Well Sir, this is incredibly interesting. The DW and I have been discussing the purchase of a tire pressure monitoring system. In watching the posts and threads on this forum, I've come to the conclusion that there is basically two "senior" systems or, brands I should say to choose from.
One is, Pressure Pro and the other is TST. After some zig-zagging back and forth on their respective web sites, I felt the TST was the way to go. I came dangerously close to pulling the trigger way more than once on ordering a system up. I just didn't. Not sure why, just didn't. It's not the price, that's not the issue, I just didn't.
But, now, in reading your post, I'm kind of glad I hesitated. I'm including a picture of my wheels and am reasonably sure they are the same wheels that you have. I too thought, while I was on their site, if a sensor will fit in the wheel slot and onto the stem. I don't know if I got any measurements of the diameter of the sensors or not. But, I'd sure like to know the outcome on this.
And, I'm also reasonably sure that you and I are not the only ones with those wheels. I suspect there's a few thousand rigs out there with the same wheels and, I also suspect many of those rigs have the TST system on them. Patiently waiting.

I recently installed the new 507 TST system on my Journey with Accuride wheels. After scratching the heck out of the first one I removed the theft deterrent devices. I had to slightly bend the front valve stems to center in the opening - no big deal. I also had to rotate the outside dual valve stems 90 degrees - again no big deal. I did have two bad senders out of 10 and had to send them back. They reported than one was ok and one was indeed bad.
After an initial slight disappointment I really like the system. Incidentally, my toad is parked about 75 ft away and still reads the tire pressures!

Nothing like getting quick response. Thanks to all. To answer the question I have the newer 507 system. There have basically been three answers.
1. Remove the outer security shell which reduces the diameter. I tried that but it did not quite fit. Oh so close.
2. Valve extenders. Thanks to those who responded with their experiences.
3. Adjust the valves so the sensors will fit. I had never thought about rotating the outer dual valve 90-degrees, duh.
Since I am in Florida for the winter and leaving in two weeks I am going to go with #2 until I get home and then go with #3. Number 1 is a good option because I do not think there are people out there wandering around looking for sensors they can remove. I doubt the casual passerby would even know what they are.
Fire Up, you can still purchase these but now you will be aware of some of the installation problems. I have no clue if the other systems have smaller sensors. I would doubt it.
Those chrome 'covers' are thin. You can easily use tin snips to cut a larger opening for either the TST or for a brass extender. If you're an accomplished metal worker, the cutout would be hard to notice.
Although the air pressure transmitters don't weigh much, I'd feel more comfortable with an installed brass extender mounted in the wheel. Les Schwab carries several different styles. Tire has to come off wheel to install them.
