RealWheels RW-PPK-0403 Air Guard Tire Pressure Monitor with Security Locking System, (Pack of 6)

I put these on my F350 pickup. Very easy to install and have worked well since I installed them. However, I wish I knew ahead of time I had to have the tire balanced afterwards. This was a cost I did not plan on.

great item

They work great.

This is a great way to quickly monitor air pressure and avoid very expensive tire replacement on motorhome
