I understand that we want to run our rear Nitto R2's at 27 - 29 psi hot for street use. For me, that means I need to have my cold tire pressure at 24 - 26 psi. Of course, that triggers the TPMS light on my dash. After the day warms up, my tire pressure goes up to 27psi, but the light stays on. So far, I have not noticed any downside to this. I have made a few hard acceleration passes and all seems fine. Am I missing anything?

There is not performance reduction tied to low pressure warning. I've got the same tires and shoot for 27-28 cold on the street vs. dealing with the warning light.

I don't think this is true. Low pressure warning is ok and won't pull any power. However, a TPMS error will pull power.

I forgot a critical word "not". I corrected what I said above

I run with low pressure in the back all the time and it has no impact to the car, no TqMgtAdv impact or anything.

Thanks, guys. Just to clarify: A TPMS error is different than a low pressure warning. I have the low pressure warning showing on the bottom right hand of the speedometer.

I'm confused, I have no TPMS sensors in my BCForged tires and i'm not seeing any power being pulled.

Correct

This has been discussed on here and this was the result. You can have 4 sensors or zero sensors and all is ok. You cannot have just 2. You will eventually get a TPMS error.

I’ve run stock Supercar3’s at 30-32psi hot on extra rims for 4 years without TPMS; and Nitto 555R2 with TPMS as my street tri-season at 32 psi cold and as my wet-track at 32psi hot. Great experience with both. And never ever pulled power with TPMS error.
