GM will not recal the computer for larger than stock. You will have to get a custom tune or god forbid a programmer to do that

With such a small difference in tire size, does it really matter? Is there any benefit to it?

His statement is incorrect. GM WILL re-calibrate it but they wont do anything for your particular size yet. The only size they've done right now is 35-36"

 

Only thing is a piece of mind, as long as you're aware you're actual speed is higher that displayed you're fine.

 

Programmer will void warranty even for just tire size because they can not tell a difference between different tunes, just logs as a change. Before anyone says it; GM can't technically void a warranty like that but good luck fighting them for it.

Thanks for the info! I think I will be better off just leaving well enough alone!!

Just ask your dealer periodically if they can fix it for you. As of now there shouldn't be anything

A GPS or smartphone will tell you how fast you're going compared to what the speedometer says, then you can adjust accordingly.

I am looking to change the stance of my 2014 silverado 4x4 and have been doing a lot of reading on the topic. I have a few questions I am hoping you all can help me with before I place my order.

 

1) I plan on going with the rough country 2.5 leveling + 1 rear. I park in a parking ramp at work with 7' max clearance will my truck still fit with ease?

 

2) I plan on putting on 20" wheels with +18 offset. For tires I want Nitto Terra Grapplers I am debating on going with either 305/55/r20 P rated tires or 275/65/r20 LT rated tires.

A) Will either of these fit with no rubbing once so ever even at full lock?

B) Which option would give me better ride quality?

C) Which option would give me better mpg?

 

I appreciate everyone's help!

1) with ease..? It will be close I think. I just went in a 8'6 structure today and seemed to be enough room with a 2.5" only Front level. Maybe someone with a RC Kit can get a measurement

2)IF it were nMe I would go with the 305s cause your speedo wont be off as much and the trans will be happier selecting gears

A) seems people with 305s and stockers, rub the front sway but with +18 it would prob clear that but then could possibly make contact with the fender linners.

B) both LT should ride the same. youll Notice the level more

C) thats a toss up since 305s are wider so they have a higher rolling resistance but the 275s are an inch taller but thinner for a lower rolling resistance. It'll come down to weight vs rolling resistance IMO so no real #s to compare. I'd pick which ever ones look better to ya.

Was this on stock tires? If so, can you get me a picture from further away. I'm trying to decide if I like it with the stock tires or if I need to wait until I can afford 33's. Thanks in advance.

    • Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.
    • The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts. 
    • I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.     
    • Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.  
    • The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
