I don't care which tire brand or size you run, but get a TPMS system. I have been using one from EEZTIRE for more than 2 years now. The peace of mind it gives me will traveling from Texas to Las Vegas to Indy is immeasurable. Easily installed and it can handle up to 22 tires. It will monitor each tire and let you know if you are having a problem and pinpoint it to the specific tire. You can set low/high pressure warnings and high temp warnings as well. It easily changes for use without the trailer attached.
It's really nice to turn it on while loading up and it will tell you the pressures of all the tires so you don't have to go and check each tire separately.
