I have the Tire Minder. 65 lb tires. Works great. Very Helpful. Small display I put on upper left of windshield. Solar (no batteries) display is nice.
Oh and for what its worth, I got a TPS because we had a trailer flat that turned into full rubber loss and riding on the rim for a while.
We had no idea the tire lost air, disintegrated, completely fell off, and killed the wheel.
A trucker drove along side us at 60mph and let us know.
$300 rim and tire later - I got the Tire Minder.
