I was just looking at tire rack and it seems the 275/60 is 15lbs more than the stock LS2s, and the 275/65 is 17lbs more (2lbs more than 275/60). I would have expected it to weigh more than that. I wonder if there is a bigger MPG hit going 275/65 vs 275/60. If anything, the bigger diameter would probably be the culprit of worse MPG.

The only reason it would be any worse would be because of the speedometer difference. Which if you recalibrate with a tuner, it shouldn't hurt it much at all. And with the right tune, probably even get you better mileage.

I couldn't take the useless Goodyear SRA's anymore so I went with 275/65/R18 since these are only used in the winter and I would like to get the best MPG I can. Night and day difference.

I have 275/65/20's on a 2015 All Terrain with a 2.5" level.................this baby feels like a caddy. I little too sluggish (need a tuner) compared to my EcoBoost but man is it smooth. This is my first set of KO2's ( others were KO's) and that's all I'll ever put on my trucks.

Do you have any other pics? Looking at this set up myself. Do you have the 5.3 or 6.2?

I have the 5.3 w/ 2.5" RC level and rear stock block. I didn't get before and after measurements but my truck still has a 3/4"-1" rake and that's pretty much where I wanted it. The suspensions on the All Terrains area little different from others and you may not get the exact results as I did if your dealing with other than an AT. Here's the only pictures I have.

What tire pressure r u running? I have the exact setup but the tires stiffened the ride a bit.

Running at 38psi

I came out of a Ford EcoBoost with Bilstein 5100's on top height and the same tires. This runs a lot smoother.

I just picked up some take-off 18" OEM wheels and put some 275 65 18 KO2s on as my snow and towing wheels/tires. The tires are pretty quiet on the freeway but are noticeably louder than the Eagle LS-2s that came on the truck when there's less wind noise. I just got home but I'm certainly pleased.

So far 50,000 miles love this tire... will be getting new ones next November. So I'm sure they will have 80,000 + on them. 275/60/20b0a2abbd72fcd5a79da3d4f35a5264e5.jpg5f2d19b984bfa8dccd1a6c4f1001e42a.jpg

And those are load range E tires correct? Not D which is standard for these trucks. How does that affect the ride quality or your mpg's? I hate that the only 18" rim versions of these tires are load range E.

 

I wish I had a non z71 with 17" rims. The money saved on the truck could have gone to immediate upgrades at shocks, metal skid plates, and better quality tires.

Yes, these are E load range and you definitely know they're on there. I feel like everything about the truck movement seems a little lazy from acceleration to suspension movement. It's not bad nor do the tires make the truck ride uncomfortable, just different. I've only driven maybe a 100 miles since they were installed so I can't say much about fuel economy. We're heading to the mountains next weekend which will be the first trip we will take in this truck.

      OCI, not when but why?

      By Chuck FB · Posted

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".

      On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?

      I'm pretty sure it doesn't actually recalibrate the speedometer it just changes the wheel speed sensor inputs to the computer. The truck still thinks it has stock tires.

      I apologize, I missed this post, at risk of going off CURRENT TOPIC.   I'm not saying it is BS, I'm questioning how much information is being held back. GM is NOT going to spell out exactly every parameter in the algorithm. Liability, intellectual property, etc.    I'm not naive enough to believe that it is as simple as revolutions, coolant temperature, miles, time; are you?    I don't do irrational either, and boiling the OLM down to four simple values that I could code in an afternoon (I'm not a coder) is irrational - unless it suits your agenda to ignore it.
