TPMS and E Rated Tires ?

[roadrnnr]

Thought I read on here somewhere that running the higher tire pressure with a E rated tire will make the TPMS sensor go off.

Can anybody confirm or deny this who is running a E rated tire and pressures of 65-80 psi.

I want to go with an e rated tire but don't want the hassles of the TPMS being on all the time.

Thanks,

why do you have to run 65 to 80 psi?

Absolutely no need to run that much pressure.

 

[roadrnnr]

Guess I don't I was just looking at the rec PSI's for the tires I am considering. I know with the heavy duty tires you can run a much higher pressure for load carrying but your right I would not need to. Been awhile since I had e rated on my previous 2500 diesel. I now want to put some e rated on my 1500.

you can absolutely run them on your 1500 with no issues. My tires are e rated and i run about 42 in the front and 38 in the rear

The absolute lowest you want to go is 38, I recommend running 40-50 psi depending in the roads you drive etc. the max pressure on the tires show the max weight that those tires can handle at the max pressure.

From what I understand, I think the TPMS may only set off a low level alarm. I'm not really sure they if they trip on high pressure?

I agree. However you could run as low as 35 psi with out setting the alarm off.

Im running 50psi with no tpms light

But on a load range e tire that's running too low for it, it's like running 25 psi in a passenger tire

35psi is 35psi whether it's in a bike tire or an LT tire.
Put the load range E tires if you want and run 35-40psi. No need for more.

I used to work at discount tire... An LT tire with a max pressure of 80 yes it can hold 35 psi no problem, but it has a higher chance of tire failure because of the weight of the tire and composition, you can put 35 psi in a passenger tire and LT tire and it'll be the same pressure, but the tires are made different and need a minimum amount of air in them to run safely

I still work at Discount Tire.
I can guarantee you will not hurt an E rated tire by running 35-40psi in it unless you load the hell out of your truck.

Which store you work at?

I bought my first set of E rated Terras from Discount Tire and they set the psi at 35 and I ran them for 50k miles, no issues. I'm on my second set of the same tires, and still running 35psi.

x2. I believe it just triggers on low pressure.

 

[lone12star]

What's the max?

All I'm saying is is that in all my training, I have always been told that in a load range e tire, to put at least 40 psi in a half ton truck, that's what I put in and never once had a problem

Just put a set of 275/65/20 Terra Grapplers on my dads 2011. Set them at 40psi and I know he'll be good to tow anything that truck will handle.

I'm in San Marcos.

If they're E rated they'll be 80 max.

Nope he just left a couple months ago. Got promoted to AVP.
Those Terra Grapplers are 80. Just put a set on my dads rig.
