Just got them on yesterday, discount tire said I need to run 40psi to keep the tire pressure light off based off volume of the new tire. Is there a way to reprogram that light/sensor so I don't have to run them so full? I can tell they are running harder in the center of the tire because the small rubber tabs on a new tire have worn on the center but the outsides of the running surface still have their tabs. Obviously running a little inflated.

 

Get a tunner or a pro cal.

It doesn't matter what size the tire is... the pressure is always the same. 35psi in a 35" is the same as 35psi in a 31" tire.

I say air it down to 30psi and you're all set. If you need to go lower, then you might need a third party tuner/reprogrammer to turn off the TPMS light.

 

I would do the chock test and get them running even and do not worry about the light till you can get a Procal to turn off the tpms! We need pics asap!

 

Yeah plan on pics today. I'll try dropping a few psi today and see how it goes. If the light comes on I may have to suck it up and put more pressure cause I can't handle that light being on.

 

What weighs more 35 lbs of feathers or 35 lbs of rocks?

Obviously the guy that told you that never paid any attention in school.

 

A 35 needs to be aired down to 28-30. Best bet is to chalk test it to find the range. At 40 you are going to wear down the inner tread pretty quick. Get a Pro Cal, it's a worthy investment and then you can shut the TPMS off and not worry about it.

 

I agree with what's been posted. Don't forget to check the pressure in your spare!
If it's different from the other tires it can set off the TPMS.

 

Yep, I run 28-30 in mine. That's where the chalk test told me to go. Those things are too expensive to wear out faster than necessary.

 

I have a Procal that I am selling. I just can't put it in the for sale section due to not having 50 posts. Send me a PM. It's only 3 months old.
