the stock size i think was 265/70R17
I need to buy new tires and was just wondering if i can just get the 275/65R18 tires, or if this is bad and maybe the owner messed up something by putting on the bigger wheels?

i don't know if it has a lift or anything, can't really tell.

i attached a picture if it's helpful at all.

The actual tire size (what it should be) is noted on a label inside the drivers door jam.

 

Assuming your sizes noted are correct, the difference is negligible.

Welcome to the site.

 

You will be fine, those are just a set of factory take offs from a 2010 Silverado/Tahoe. Basically same size as the 17's.

Those rims look good on that truck. The truck looks stock, so if I were you id just keep it as is and replace the tires per normal.

The size of the stock tires the truck came with is (or should be) listed in the driver's door jam on a Max Load rating sticker.

Find a tire dealer that's a pro and trustworthy (maybe not a person in greasy, dirty coveralls with a runny nose and holes in his tennis shoes) and consult with them.

IMHE&O tire dealer's prices will be roughly within 10% of each other all over town. They make their money on the mounting, balancing and Road Hazard Protection. I'm a HUGE believer in Road Hazard protection; tires cost a lot of money!

I'm no expert, but I'm pretty sure that as the ratio number (ie. 70R or 65R) gets smaller, so does the overall height of the tire. 

they make widths in several aspect ratios - a 245/45-17 will be tiny compared to a 245/70-17 (i used that size because i have the 245/45's on my OBS since it's dropped to the pavement) 

 

can't really tell if it has a leveling kit (it looks like it might though) - but it certainly doesn't have a lift - easiest way to test for level kit is to measure ground height just behind the front wheel well, and also just in front of the rear wheel well (providing all 4 tires are the same size and have similar wear) - if the numbers are the same it's leveled - if the front is lower by an inch or 3, it's stock height.

      I never understood the hate for the column shifter. The console shifter just gets in the way, takes up prime cargo space and in my wife's Jeep, the dog constantly bumps the console shifter into neutral!    Best choice ever to just make it a column shifter across the lineup and be done with it.    (Bonus: Makes swapping from a 5 seater to a six seater far easier)

      Wow I'm in a pickle. (Broke down truck) and a story.

      I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.
