TST System

Second time out with our like new 2012 3582rl Monte. Installed the TST 507 monitor system. Followed directions on pressure settings. G rated tires call out 100 lbs pressure. Set high pressure setting to 20% or 120 lbs. Got on the road. 85 degrees out and humid. Three tires stayed at 117 except one went to 120 set off the alarm then climbed to 121 and stayed there for the rest of the two hour trip via highway. What do you folks set the high pressure alarm at and should I be alarmed. I read this tread and I think 20% should be 25 or 30%
Thoughts?
Thanks

I set mine for 137. That was based off 110psi with a 25% increase. I'm going to runn 105 this next trip and back that down just a bit to whatever 25% is. When you aired the trailer tires to 100psi what did the TST reflect? If it isn't the same thing there will be a variance in the percentage you figured.

It's % * Max tire pressure. Not % * any tire pressure you set.

So if 20% is what your good with it be .20 * 110 = 132

I believe mine are set at 140 for 110 PSI cold tires. I tend to watch for a single tire temp or pressure changing significantly from the others vs what the overall temps and pressures are.

If your tires continue to heat to 135 degrees it could be that you are overloading them. Find some scales and check it out.

You could also slow down 5 MPH on one leg of your next trip to see what the temp goes to. The closer you get to the axles maximum load the more effect the tire speed will have on higher temps.

I'm running G614's at 110 psi cold. TST monitoring system (not sure which model-recently upgraded to the latest). When I was going through AZ almost two years ago my tires got up to 137-138 driving 65 on the interstate. I use Southwest Wheel here in San Antonio for all my tire/wheel/axle work. I trust them implicitly. They have been in business for almost 100 years and do everything from "routine" maintenance to custom building trailers for everyone from motorhome owners to South Texas ranchers to you name it. When I quizzed the owner he told me that unless one tire is significantly higher than the others as far as temperature or pressure goes (or low on pressure) not to worry. So far so good. My $.02.

We are seeing pavement temps of 140 - I would not expect to see the tires run much cooler than the pavement.

I keep my tires at 110 psi especially this time of the year. If you are traveling on concrete then your tires will heat up less than on blacktop but most people travel on blacktop more than concrete. At 105 psi your overall pressure may be as high or higher than the 110psi because of more tire surface on the road.

Thanks. On my initial drive from TX to FL I ran at 110psi. When I hit expansion joints and holes I felt the jolt from the truck hitting and then the trailer. I never experienced that with my last trailer and the MorRyde suspension. This one has the Road Armor so don't know if it's as good or not yet. I also went from LRF to G before I took it off the lot (and they are overkill for the trailer) so that is a contributor as well I figure. Want the LRG and won't go below 105psi so guess it would be putting a MorRyde on in place of the Road Armor if that is the cause.

My tire gauge differs about 3 psi different then my TST 507 readings . I set my high pressure a bit too low, and got the warning. Had to reset , one tire creeped over 1 psi on the high pressure setting. I usually run 100 psi on my G rated tires .

So at what point do you get concerned with the stock rims being rated for 110PSI?

Me personally I don't worry about the wheels. Pretty sure like the tires rated for 110 psi, they know pressures will increase as it heats up. I am seeing at times around a 20 psi increase in tire pressure .

I would worry more about my stock rims cracking from hitting chug holes than from tire pressure. The spokes in the aluminum wheels are the weak point and i had 2 go bad so replaced all with modular wheels.
