I think Discount Tire can service them. I don't know if they can adjust them or if they'll just remove them.

BTW do you get any rubbing with those tires? what kind/size are they?

they are 305/70-16 Pro-Comp X-terrains on 16X8 micky thompson classic lock rims. i have a 3" body lift and my torsion bars were turned like 7 turns to level it and they rubbed if you turned really sharp. but now im adding a 4in skyjacker lift so they wont rub at all. i just wish i wasnt working so much so i could finish the damn lift! haha. but yeah 33's wont fit unless you have a lift..

also i dont really know how the TPM works so is there like a sensor on the truck and on the tire or rim or just the truck?? because if its on the tires as well as the truck then that might be why they are not reseting for me because my 33's never had any type of sensor put in. or is there like a fuse i can just pull for that?? haha

There's a sensor in the wheels that tells the computer how much pressure is in there.

If the sensors weren't placed into the new wheels, it's reading zero and that's why you have the warning message.

I believe the sensors are in the valves, but I'm not 100% sure.

exactly, the sensor is the valve stem assembly it's self, you have to have the foctory stems.

DAMN thats badass man, yeah I had thought 33's wouldn't fit and didn't know anything about your truck so I asked. But I can't wait for the day I get to do that kind of work on mine.

IIRC the way it works usually is there is a transmitter on the inner side of the wheel attached to the valve stem, and a receiver in the wheel hub. Anyways it *may* be on its own fuse but chances are its on the accessory one, I would check your manual.

TPM sensors are the valve stems. Notice how they're aluminum instead of the traditional rubber valve stems? Any vehicle you see with aluminum valve stems youll know it has a TPM system.

And no theres no receiver on the hub or anything, it sends the signal to the passenger door module or BCM can't remember which I know on the full sizers its the passenger door module.

If it says "Service tire pressure warning system" then that means theres a problem not relating to actual tire pressure but an actual problem. Could be they forgot to install the sensors or they may have damaged one or more during the tire instal this is common too. I would contact the place where they installed your tires and let them know of the situation, tell them you want to take it into a dealer and if it turns out to be a damaged sensor then its on them. They'll wanna work with you when you tell em that.

i actually ordered my tires and rims as a combo from 4 wheel parts so they came mounted and balanced. so the sensors were never put in the wheels because i knew nothing about it. i do still have my stock tires and rims, so do i just take them out and have them installed in the new rims and then reset the TPS system to the correct air pressure??

Is there a way to disable the feature? I mean can you turn it off so you get no warning on the dash? Mine seem finicky and I could care less if they go in my new wheels. :hs:
