E load range tires

[slimjim2525]

I have a question about e load range tires. I have the truck in my sig. I just had michelin LTX A/T 2 tires load range e put on. I chose e load because i sometimes put a fair amount of weight in the truck and tow a trailer that can be swayed by the wind and wanted a stiffer sidewall. They put them on and noticed they only put 36psi in there. I went back and told them that I thought e load should have around 80 psi. They put the tires up to 60 psi because "they forgot" and immediately my TPMS starts flashing and now I get a service TPMS signal with the yellow tire symbol on in the dash. I showed them this and they told me the TPMS would equilabrate over time. Drove it home and no change. Questions are. Can I put a e load range tire on a 1500? If so do I need to wait and will the tpms equilibrate? Do I need an ecu flash if that's posible. Do I need different tires? Help from gm techs or tire guys is greatly appreciated.

yes you can put E load range on your truck. No the tpms will not adjust. You should be running what's in your door tag for pressure. (i keep mine around 40psi) GM MAY or may not change yours to a higher rate since the HD obviously has the higher rated values in the computer. You can either run them at 40 and inflate more for towing and deal with the light only when towing. deal with the light always. convince gm to change the values. or go back to a lower rated tire, which will still have a higher psi rating on the tire than will actually be in it.

 

I run E rated tires inflated to 40psi with no lights.

Do you get wear issues at that tire pressure?

[kstruckcountry]

35-40 psi is about right for e's on a half ton. If you need to inflate them more than that you may be overloading the truck. If you do need to inflate them more, do it. But without a load the ride will be awful at 80 psi. I used to run the e's on my old truck at 25, and they still wore more evenly than most.

[slimjim2525]

OK i get it. I traded a 2500HD in for this truck, and always had e load range tires at 80 psi on my 2500. I thought they had to be at that psi. I will lower them to 40 psi. Do you still get the benefit of the stiffer sidewall at the lower psi?

[wurgs]

Yes the sidewall has more plys than p rated tires so will be stiffer. I've been driving with E rated for about 3 years now with no wear issues. I run them at 40 lbs but when hauling or have a heavy load in my bed will go up to 50 lbs or so. My warning light doesn't come on till it goes above 50 lbs. The dealer can change it so it won't come on till higher pressures but you really shouldn't need it. Make sure you rotate regularly and you will be fine.

I dropped them to 40 lbs and I still have the service tpms on start up. When I try to look at the tire pressures it just shows two lines. Could the tpm sensors be damaged? I tried to disconnect the battery and it still has the warning on the DIC. Any suggestions??

I just looked at my onstar from my phone and it says recommended 60 front and 75 rear....my rear are yellow and are 6 and 7 below...front shows good and are 3 and 4 below so it seems they go off at 5 below....maybe the lines are because tours are so low from the recommended

I run E's on a half ton for the exact same reasons as the OP. And it was successful.

 

Currently, I run about 50psi on all four tires. I have tried 65 on fronts, 80 on tears, and I got hemorrhoids from that ride.

 

I love my E tires. Fixed my trailer issues.

try driving to see if it registers. if not you may have a faulty sensor

[sab316]

Have you tried resetting your sensors?

As stated, E range tires are fine on a 1500. I've been running them for two years now. However, there is no reason to ever have the max psi in them. You only need the max psi when you're hauling the max amout of weight the tires are rated to handle.....which shouldn't be done with E's on a 1500 anyway. As far as your TPMS goes...it won't fix itself. That dealer is full of poop. You can try resetting them first. If that doesn't work, take it to a dealer. I had the dealer set the 'magic number' on mine to 45 psi. That way, I can run 38-40 normally, and bump it up to 50-52 when towing....and the TPMS is always happy. Good luck.

[slimjim2525]

How do you reset the TPMS? Is it the same as the tire relearn? I still have the warning light on.

TPMS = PITA!

I'm running 45psi in mine. Seems to be good. Ride is no harsher then my old p tires at 35.
