Low Tire Pressure

[BLACK REV 800 X]

Quick Question: I just took off my 20 inch summer tires and reinstalled the factory tires. I performed the TPMS reset by lowering the pressures and that worked fine and pressures match the DIC readings and locations. The only problem I have now is the low pressure light is on and won't go off. I will redo the TPMS reset again tonight as it is easy and have done it many times, but have never had a problem with the low pressure light staying on... 34 in fronts and 32 psi in rears. Thanks.

32 psi is too low

your truck should be looking for 35 psi

Thanks - I'll give that a shot but had been running 32 /30 in my NNBS 07, and 32 / 30 with this truck with my OEM 20s all summer.....

Not to steal the thread but quick question. This is my 1st vehicle (10 HD2500)with TMPS. Is there a percentage of play in the TMPS before the low pressure light comes on or does the PSI in the tires have to be dead on? Reason I asking is my rears are at 72 PSI and would like to go lower. Thanks

My 08 SD wants 30PSI F/R. When the light comes on, they are about 28PSI. I'm guessing it'll trigger if it's 2PSI low.

Wow... Lower yours down to like 45 rear and 50 fronts and you'll probably notice ALOT better ride. Its probably like your skating on ice right now...
