So after a lot of research it seems like 265/70r18 might be the tallest P rated tire I can fit on a stock height Silverado with my factory 18 inch wheels. It's probably the size I'm gonna go with once the stock goodyears wear out to gain a tad more ground clearance and get a slightly more aggressive A/T tire without lifting/leveling my truck and ruining the comfortable stock ride it currently has. I'm wondering if anyone has any pics of this size tire on their stock height truck?

Or you could go with a 285/65 18" if you want.  I don't think I have ever seen a 265/70 mainly because most go for looks over function and that size will be tall and skinny looking.  The 285/65 will give you the same height (32.6") but a wider foot print and will look much better on the truck and will still fit on your stock rims.

well that's an odd tire size, and there are not any trucks that come from the factory with that setup. Most come 265/65/R18.

 

265/70/R18 is only a 1" taller tire overall. Meaning that it is only going to "lift" the truck 1/2". Almost going to be unnoticeable. I doubt that too many people even go with that option because it is not really a significant increase to warrant getting new tires.

I don't know how odd that size is.  I was thinking of that size as well.  It gives just a bit more tire size without needing a level.  I agree though that not many would pull off usable tires to change to this size.  I will be waiting until my oe tires are worn out.  The 285/65 option does sound interesting as well, but I would think the 265 width might be better in rain and slushy snow.

My thoughts exactly. I'm gonna wait until the stock wranglers wear out, then probably switch sizes when that happens.

Tall narrow tires are great for deep snow. I had 265/70/18s on my ‘08 and I’ll most likely get a set before winter for the stock wheels for my ‘16.

It does not rub. It is a 4X4 Z71 CC STD Bed.

i think the 4x4  z71 has a higher stock lift and suspension profile than the standard trucks. Thanks for the info!

Last tire purchase I struggled with the same dilemma.   There is nothing to gain by going with a higher aspect except a perceived better look.  Nobody else will notice or care.   The slightly larger and heavier tire will not improve performance, economy or function.  In the end, I decided to go stock.  However, my situation at the time was different and expenses required a higher level of justification!  If you decide to go with slightly bigger tire then I definitely vote with tnchevy and say go for the 285/65/18.  The look will be noticeable and you will have the same height as the 265/70/18.  (I heard the argument about wider tires reducing traction in snow when I switched my '00 Silverado's tires from 235 to 245)  Tall, skinny tires have their advantages/appeal but it would require very unique driving conditions to have a 265 mm wide tire out perform a 285 mm wide tire.

Problem is most all 285/65/18's are E-rated tires so much heavier and rougher riding than SL tires. Plus a 285 I think would be close to if not having a rub issue in many cases? I went 265/70/18 with a 1.25 Bilstein level (1.5 spacer before) and I noticed the inch. Wider tires although improve grip in some cases are worse in others mud, snow, ice and have more of an mpg penalty even before the added E-rated tire...

Unsprung weight is definitely a consideration.  On my last truck I switched from Michelin LTX MS2 P rated tires to Michelin LTX MS2 LT  rated tires.  (Same size-same pattern)   I felt the switch significantly hurt my MPG's. although don't have data to support my "feeling".

    • We have now!  2027 GMC Sierra  Early look, but I'm a GMC guy and so far I think I like the looks of the Chevy better.
    • HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.      
    • I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it. 
    • So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.
