Need your help on TPMS and different / larger tires & rims

[Fallz]

Ok , I have a Sierra CC 4x4 . It has a 2" leveling kit on the front . I called my local 4x4 tire shop who I have dealt with in the past . I am looking to upsize tires to a 285/65/18 ~or~ a 285/70/17 . These size tires are all "E" rated as I'm sure you all know that. They have told me it will be a problem because my TPMS won't register properly because of the much higher tire pressure with E rated tire and the light will stay on all the time. So if you guys can give me some education on this I would appreciate it. If I decide to go to 17's (my truck has 18's chrome clads) I can get tires and rims cheaper than the 18's so I'm not sure what I will do as far as that goes.

 

My truck is black and I want a simple type of rim without a lot of bling so I am going with AR 321 Fuel rims . I do not how to post a link or pic so I can't do that to show you , sorry .... The rims also have a clearcoat on them so it will be easy to clean and be protected a slight bit better with winter road salt .

 

I talked with them about tire's and I have had many of sets of BFG AT's in the past and they have been a decent tire but would like to try something different so I am thinking of Cooper Discover AT3's or GY Wrangler Silent Armor . I like the looks of the Duratrac's but afraid they won't be so good on hiway , ect.... and be to noisy . I do go off road but to be totally honest 99% is on road and in snow ect...

 

Give me your thoughts ect....

 

Thank you

Mike

I have 18's 295/65 on Fuel wheels with TPMS sensors installed running 45-50 PSI and all is fine.

 

I also have 275/75-18 on stock wheels with sensors installed and they are fine.

 

I don't think you will see a problem unless you run maybe 60PSI or higher.

 

Will the TPMS light come on if my tires are overinflated?

Not necessarily. The TREAD Act/FMVSS 138 requires the TPMS warning light to come ON when the tire pressure drops below 25% of the placard tire pressure. The TREAD Act/FMVSS 138 does not require the TPMS warning light to come ON when the tires are overinflated; however, there are systems available that do warn the driver of overinflation.

I have the Duratracs on my 2500. Noisy? A wee bit but nothing like you'd expect from them. Great in mud,snow and on the highway

As long as you re-calibrate your TPMS you should be fine. Just did that with my larger wheels/tires.

I went with E-rated tires a few months ago due to I do alot of towing... I found everytime I aired up my tires to 70 lbs+ my TPMS light would go off so I went to the dealer to re-calibrate my system for up to 90 lbs of tire pressure and never had another problem. Dealer told me that when a person goes to a tire pressure greater than 50 lbs that the TPMS light will go off so made sense to me to have the system re-calibrated.

I have LT275/65/18 BFGs on mine and as cs said it will only give a warning if pressure exceeds 50 lbs. Unless towing pressures that high aren't needed, will make your truck ride way too firm. I normally keep my tires at 40-45lbs ( my tires seem to wear the best at this pressure) and air up when I'm towing.

My truck had 20's from the factory, and I replaced them with my current setup. The TPMS was looking for 30 psi from the factory, because of the P-rated 20" tires. So, I had the 'magic number' set to 45 psi when I changed to E-range tires. That way, I can run 40-45 psi all the time, and then bump up to 50-55 psi for towing.....and the TPMS light never comes on.

Ok thanks . That make perfect sense . Just gotta decide on tires .

 

The Rod , that truck looks sweet !!

Thanks, I'm very happy with it!
