2016 1500 sierra TPMS

[gmyeah]

I did a search and couldn't come up with what I was looking for.  I'll be do for tires soon and I want to go with LT tires on my half ton.  The only issue is there are limited options in terms of an all terrain tire and load ranges.  I'd prefer a tire of the same size (265 65 18) which is my stock size due to my spare is that size.  My issue is the choices are so limited that the are Load range E generally.  If I run my tires at 60PSI will my TPMS go off.  DO they only look at if your are too low.....or is it a range......and can it be re-taught  to understand a new range at the dealer.  Just looking for options.  Thanks.

This use to be easy when I would get  load range c tire for my truck....

My sensors read 48 psi

If I’m not mistaken, it only sets off a light once the tire goes below a certain PSI. I run 45 - 50 PSI in my Toyo’s with no issues.

When I replaced the crap 275/55/20 SRA's on my 2016 RCSB, when valve stems were removed prior to tire change, all 4 TPMS units notified me via On Star @ 20Psi (there was a low pressure issue).

Installed BFG K02's 285/55/20 using same TPMS units with no issue and now run 48Psi with Nitrogen...

 

I believe the 20Psi Plus or Minus 2Psi is the detection range for low pressure warning.

 

Also,, had rental care in Florida / G50 with tire issue and it send notifications starting at 21Psi..

 

Hope this helps...

You're in for a harsh ride if you inflate them to 60 PSI.  I generally run mine between 40-45 depending on the load.  They seem to ride the best with no load between 40-42 PSI.  I'm running LT285/60R20 Cooper Discoverer AT3 tires.  My next set of tires won't be LT tires.  The extra weight of the tires does affect gas mileage.  When these wear out I plan to go with Nitto Grappler 305/55R20 Extra Load that is lighter than a LT tire by a few pounds.

Don't let the size of your spare limit your choice of new rubber. The point of the spare is to let you limp home or to a shop in an emergency. If you have larger tires on your truck and you blow one, just put the spare on front so you aren't burning up the differential.

 

FWD cars can run on a donut on the front for miles and I haven't seen one blow up on the highway yet. Even though they say somehting like 50 mph max, how many times you see people cruising at 65 with a tiny spare on?

 

Anyway, the difference with a full size truck spare is it lets you operate the vehicle normally. I doubt anything you put on your truck would be as out of proportion as a donut on a car.

So choose whatever tires you want and don't worry too much about matching the exact size of your spare.

Thanks for the info!  yeah, the only reason for the same size was going to be convenience.  Say I'm camping 1000mi from home and get a flat on a rear tire.  I'd like to change it and drive home instead of making sure the spare goes on the front.  Purely convenience.  If I change my size a bit say to 275 65 18, it only changes my tire by ~1/2 in height and width.....and my tire options are much more.  Hopefully I can drive a 1000 miles and not worry about the size difference for 1000mi.  Having a full size spare is nice.  I've gotten better tires (LT) on a 1/2 tons for years and I wouldn't do it any other way, now I just have to think about it way too much.  Most likely I'll just move to a 3/4 pickup and drive it stock vs all these mods on a 1/2 ton.  Lesson learned...
