I have a 2018 Scamp
that I had those same thoughts as well and decided to do something about it. After I had pick up my new Scamp
13 at the factory I found myself traveling through the Midwest on Interstate highways that had higher speed limits than here in the Northeast. As such I found at times I was traveling at close to those posted speeds.
It wasn't until I got back home after some 7K miles of travel that started to read stores about travel trailer tire blowouts. I found that the standard tires
on the Scamp 13 were rated at a max of 65mph. That was a bit uncomfortable to me knowing that at times I might be traveling at close to those maximum speeds.
I decided to do some searching on the web about travel trailer tires
and decided to replace my tires with Carlisle ST17580R13 tires. They still have a maximum inflation of 50psi but have a top maximum speed of 81mph. I now feel a lot more comfortable knowing that I can travel at 65+ at times when necessary and know I am not on the edge of my tires max speed.
I know that I might get some flax here for stating I might run at the 65+ speed but at times it may be necessary. Given the choice, I prefer the higher rated tires over the monitoring system. I am not saying that the monitoring system should not be purchased, but if you run over something that cuts a tire on your Scamp13 you will most likely feel the problem before it registers on the monitor.
Knowing how to handle the Scamp blowout, by staying off the brakes
and maintain your speed until you can bring the Scamp under control is most important. Then pull off the roadway where possible. Above all, don't panic.
As a routine I check my tires when cold before we leave and whenever we stop to see if any one tire is warmer or hotter that the others. Get yourself a good tire pressure gauge and know how to use it.
