TPMS

[palmettopowerstroke]

I'm sure this is already posted somewhere, but I couldn't find it. What happens if I do new wheels and tires without TPMS sensors in them? Will the light on the dash stay on or will the system just not alert? I'm looking at either Nittos or Toyos 65 psi rated and don't know weather to put the sensors in or not. Thanks

the light will come on but a H&S tuner will turn it off

if you get tires with same psi rating, front and rear you will not have a problem.

Just run 65 psi and you will not have a problem The TPMS sensor goes off around 62 psi.

At 65 psi, you are giving up 600 lbs per tire in payload to the oem 80psi tires. So unless you are running empty all the time, You will probably want to max out your pressure to have SOME payload with those tires.

Explain how 15psi gives up 600lbs of capacity please. Never heard that. I'm genuinely curious.

Ok that's good about the threshold being 62. I ordered toyo open country 35x12.5r20 with XD monsters and got them to put the sensors in. Going to be a daily driver for the most part so the loss of capacity isn't too much of an issue.

Go look at the tire specs. Take a look at two tires that are about the same diameterto compare, here are two Nitto tires for example

35x12.5x20 Max Pressure = 65 psi Max load = 3195lbs
LT275x65r20 Max Pressure = 80 psi Max Load = 3750lbs
Ok, so it's 550lbs lighter. I was off on my 600
Times by 4 tires on your truck you just lost 2200 lbs of load capacity on your tires if you go with a tire that has a 65 psi max pressure rating vs an 80 psi tire.

Any of the floatation tires ( 35x12.5x20 or similar numbers) are maxed at 65 psi.

Any of the Light Truck Tires ( LT275/65r20 or similar numbers starting with LT) and being a load range E will max out at 80 psi.

My hancooks max at 65 but are a E load range. They are 37x13.50x20.

I've seen E rated tires and D rated tires have the same load carrying capacity before at different air pressures. It has to do with how the tire is built and designed more than the amount of air it can hold.

[Painted Horse]

True.

but a "E" rated Floatation tire will have a max pressure of 65 psi and have less load capacity than a "E" rated Light Truck Tire of the same diameter with a max pressure of 80 psi.

Floatation tires are measure in inches i.e. 35x12.5x20
Light Truck Tires are measured in Metric Numbers and have the letters LT in their size i.e. LT275/65r20
Both can be "E" rated. Both will be approximately the same diameter. In this case the 35" tire is 1/2" taller than the LT275
