07Serria Posted August 11, 2014 Share Posted August 11, 2014 Hi all, I got a new 2015 2500hd. The truck is my daily driver, I don't haul or tow anything. The required tire pressure to keep the sensor off is ridiculous, if you are not hauling or towing. I have been running around 60psi all the way around and so far this keeps the sensor light off. However, I would still like to run less in the rear tires, to avoid wearing out the center of them. My question is what are you guys running for tire pressure? Have you had problems with the center of the rear tires wearing out from running higher pressures? Have any of you been able to get you trucks reprogrammed to lower pressure numbers? Thanks Link to comment Share on other sites More sharing options...
johnnyace Posted August 16, 2014 Share Posted August 16, 2014 Great question. Anyone know how low the pressures can go before triggering the sensors? Link to comment Share on other sites More sharing options...
Zebrafive Posted August 20, 2014 Share Posted August 20, 2014 Approx 10psi. I am not sure if you can have the sensors recalibrated or need new ones with a different setting. Link to comment Share on other sites More sharing options...
seasled Posted August 30, 2014 Share Posted August 30, 2014 They are load range E tires if you run them any lower you will wear the outside edges (under-inflation)of the tire.those tires are built to run at 70 to 80 psi because of the 10ply construction, if you are trying to soften the ride since you said you don't haul or tow anything, you may need a 1/2 ton verses a 3/4 truck if this is the issue?

johnnyace Posted September 7, 2014 Share Posted September 7, 2014 Factory recommended pressures are 60 front 75 rear. 5 psi deviation should be no problem. Since they are the same tire front and rear, 55 should be acceptable all around when not towing/hauling.

Sent from my iPhone using Tapatalk I agree. 55 was what I ran in my 1999 1/2 2500 with LR E for 200,000 miles. 80 was for when I towed a horse trailer.

48548 Posted September 17, 2014 Share Posted September 17, 2014 You can change the pressures of the sensors with a tech 2. Link to comment Share on other sites More sharing options...
Big Whiskey Posted September 17, 2014 Share Posted September 17, 2014 The TPMS is set to look for a 'magic number' of PSI, and will allow for a certain variance (I'm not sure exactly how much) either way before it trips the light. On my dad's 2500HD (gas engine), he had the number for all four tires set to 60 PSI, I believe. That way, he can run 50-55 when empty, and bump up to 70 when towing. You don't need to run 70-80 PSI when empty. That being said, the diesels need a little more PSI in the fronts than the gassers do, because the engine is much heavier.

tramz Posted September 17, 2014 Share Posted September 17, 2014 Factory recommended pressures are 60 front 75 rear. I run less in the rear than I do in the front unless I have a load. Don't follow higher pressure in the rear. I've always ran 10 ply tires that call for 80 psi at max load. Under normal daily commutes I run 55-57 front and 46-50 rear (1/2 Ton) and tires have always had even wear across the tread. I also think depending on tire width and wheel width combination pressures could differ. This may not address the sensor question but may help with pressure question.

Cowpie Posted February 12, 2015 Share Posted February 12, 2015 The factory tire pressure recommendation is base on the maximum GVWR of the pickup. NOT on what loads the tire is actually running. Case in point... for commercial truck tires, the tire OEM will have load / pressure charts that give the proper tire pressure to run on a tire based on the load on them. Max load, pressures higher. Lighter loads, reduced pressure. A tire has to do more than just turn. It has to provide effective braking, absorb road shock, etc. If it is over inflated, based on the load on them, they will not stop the vehicle as effectively and since they are stiffer due to higher pressure and light load, they will not absorb road shocks properly and transmit that to the axles and suspension components, wearing them down faster. Unfortunately, the pickup OEM didn't give us the proper load tables, nor are they readily available from the tire OEM's for light truck tires. But sure thing, the factory pressure recommendations for LT tires on something like a 3/4 ton is way out of line if running empty or very light.
