The title is a reasonable question. It a little like asking if you should buy insurance. What does the data say? But first lets be sure we all know what a TPMS is. Here is a video I found on YouTube:

A few years ago there was a survey done of 17,000 RV owners concerning tires. One of the bits of information to come out of the survey was that 32% of towables and 19% of motorized RVs had experienced a tire failure in the previous three years. Also that of the towables that had a failure, 66% were on tires three years old or newer and for motorized units 63% of the tires that failed were five years old or newer.

Given the cost of replacing a failed tire on the road when you can’t shop for a good deal and the potential for hundreds or thousands of dollars worth of damage to your RV, don’t you think that spending $60 to $80 a year is a good deal for a system that can provide warning in a very large percentage of the cases, such that you can pull over before the “blowout” occurs?

If you have an air leak because of a puncture or small cut or leaking valve you might even be able to stop in time to save the tire itself so it doesn’t end up looking like this?

RLOF 2011This tire had a puncture but the driver didn’t know it till it was too late and the tire shredded itself.

If they had a TPMS there is an excellent chance the driver would have received a warning long before the tire was destroyed.

There are a number of TPMS on the market today. All new cars sold in the US for the past few years come with TPMS. For RV owners a quick look through any RV magazine on on an RV Forum or Blog will show you a number of different TPM systems.

If you Google “TPMS exterior sensor images” you will see the variety of external sensors available today. There are different features and I can’t know which features you feel are most important for you. Some want a long warranty others like a large monitor screen, some demand a replaceable battery.

BOTTOM LINE what ever features you feel are important you will see that when you look at the life of the system and factor in the cost of replacement batteries over a 3 to 8 year period the cost is less than 1/3rd the of the cost of a tire so given the odds of having an expensive failure, the pay back for this “insurance” is better than just about any other type of insurance you can get, so if you don’t have one today, get one as soon as possible and improve the safety of your travels.
