I wouldn't think it will be much different being that my truck is a 2016 but my cold pressure is suggested at 35psi. I can be at 28-29psi and the light will not be on yet, usually starts at 27psi. So given that you have roughly 7psi before it would come on.

 

Or just lower one tire to see where it comes on and your question is answered.

I have an appointment Saturday to have them installed at Discount Tire.  I called and confirmed that the P metric recommended PSI is 35.  They told me they could re-calibrate the TPMS for me, we'll see.

The TPMS warning usually comes on pretty low.  Like under 20 or something.  I did some sand running and put the pressure down to 22 I think and never got a warning.

Man, what a difference.  Truck rides like a Cadillac now - smooth and quiet - at least compared to the Duratracs.  Even my wife said she couldn't believe how much it improved.

 

They set the tire pressure back to 41 so I lowered to 37 after it cooled down with no warning.  I may go a bit closer to 35 after driving it a while and watching the pressures.  Best mod so far, at least for me.  Happy camper at the moment.

What pressure did you end up sticking to? I ask because I recently purchased the same tire size and load rating (275/65/r18 116, Duratracs funny enough - I wanted to stay away from the LT versions too)  and have been trying to nail down the best pressure. Usually just stick to 35 but I’ve noticed my fuel economy has been pretty bad at that pressure.

I set mine at 36.  No issues at all and my mileage is much better - but it's a different tire altogether.

Makes sense. I was told by multiple shops to set mine at 38 psi (max is 51 psi even on the p metric duratrac tire). Just wanted to see what you ended up with. Thanks.

      Yeah I don’t leave ANYTHING just sitting supposedly maintaining my battery on a vehicle or RV for multiday periods. I connect a charger as needed to provide a full charge, then disconnect it and either monitor the battery or follow a set schedule for periodic charging.

      Get the 5.3. I`m not a Ford guy.😉   I think these L84`s are less problematic than the L83`s. Certainly less than the L87.

      NEW TRUCK

      By PUSSLEGUT · Posted

      I have finally paid off my mortgage and can now purchase a new truck. I would greatly appreciate any opinions on the purchase of a new 2026 GMC Denali 5.3L or 6.2L with the Denali reserve package. I am not interested in the 3.0L.  Or should I go buy a Ford?   Thank, John

      One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...

      L8S For 2027

      By C/K Man · Posted

      'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine.
