I understand I'm asking a group of non-tire salespeople for an opinion. But a lot of you have way more miles towing that I do. While I've been pulling the 5'er for 20 years, most of the tips are less than 500 miles round trip. But end of summer we're headed on a trip that might go 3,000 so now I'm way more concerned.
In setting up my new TST TPMS I noticed that my truck tires indicate max cold psi of 80. The door sticker on the truck indicates 55 psi for the front and 80 psi for the real (I'm assuming these are both max under the maximum tow weight?) Finally, I kept notes from the last trip to Les Schwab and their expert opinion was to run the truck tires at 50 psi for day to day driving and then increase to 60 psi on the front and 75 psi on the rear tires when towing.
Now that I type this, I realize that Les Schwab's suggested towing psi is probably close enough to that indicated by Chevrolet's sticker. Does 60/75 seems appropriate given Chevrolet's suggested 55/80?
Regards the TST TPMS - I bought sensors for the truck tires (I figured if I'm finally going to pay attention to tire pressure, I might as well pay attention to the truck as well.) The TST unit doesn't include a way to program different tow vehicles so I'm thinking A) set the TPMS for towing and just don't monitor when not towing (since the lower non-towing pressure will trigger all the alarms,) or B) manually change the tire pressure settings when towing and not-towing.
My gut tells me that not monitoring when towing and leaving the settings alone is the "best" option. Less work and I've never had a blow out on the truck. And if I'm not towing it's unlikely, I'm driving very far from home. At 8 MPG I avoid driving it at all costs.
Love to hear what you big mileage towers suggest.
Thanks!
