New tires and TPMS

I have aftermarket wheels and tires on my 2019 tundra. These new tires can go up to 80 psi. I am running about 65 psi. How do I get my tpms to work with my new set up? I tried what the manual said without any luck. I’ve watched a few videos but not really sure about my next steps. Any ideas from others who have done this? Thanks

 

Just because the tire can hold 80 psi, that does not mean you have to run higher psi. The higher psi is based on load, say if these were installed on a 3/4 or 1 ton truck that requires higher tire pressure to accommodate the load.

You’re in a half ton truck, nothing you will ever tow or carry would warrant 65 psi. You don’t need to run any more than 35-40 lbs in them. When carry a heavy load, or pulling a heavy trailer for a long period you can bump up to 45 or 50. But 65 psi is way to high and will just cause the truck to ride like a wagon wheel and reduce life due to over inflation

Also, if you’re running aftermarket sensors, most likely you’ll need to put the oem back in. 18-21 tundras are super finicky with anything other than oem sensors.

 

Drive to discount tire, etc and they can switch over the tpms. It is odd whomever installed didn’t do that, if that’s what you mean (that the psi isn’t showing up in the dash and or the TPMS light is on depending on your dash).

65psi is likely way too high for your truck weight, do the caulk test and start around 40psi and dial in from there. I run 38psi with Load D tires. I you run too high like that you will wear out the center of your tire and have an uncomfortable ride.
