Most of the reason for the mileage drop is because the tires are soft (off road), which create more friction and a loss of mileage...take a heavy LT highway tire, doubt you would see any loss and possibly a gain.

 

Case in point, the same truck and the same size tire (one was a Pirelli STRa and the other was the Bridgestone Revo II, both in a lt265x70r17)...with the STRa I could easily pull 21-22 mpg, swap the Revos on and the absolute best I could pull was 17 mpg. But I also pulled over 100k miles on the STRa with more to go, but burnt the Revos out in 35k miles.

So why want the post the UTQG tread wear number with LT tires and they will with the passage tires the tread rubber should be of the same compound as the P rated tires the strength come in the belts and plys ? It would be nice to know.

I've had LT tires for the last 11k miles. The first set were Cooper ST Maxx LT 265/70R17E's. On average I got 22 mpg at 65mph with 3.08's, 91 octane fuel, AFM disabled and 6th gear locked out. I sold that set and bought Toyo Open Country AT2 LT285/70R17E's. Over the last 2500 miles my average highway fuel economy is 21.5 mpg at 65 mph, 91 octane, AFM disabled, and a Blackbear tune for better transmission performance. My city mpg's on the other hand got hit hard. 17 on the stock Continentals (P275/55R20), 15 with the Coopers, and 13-14 with the Toyo's. The Toyo's are inflated to 45 psi front and 40 psi rear. I air up when I do any heavy hauling or towing.

 

Personally there's no way you'll see P tires on my truck. Way too many bad experiences with junk on the highway punching holes in the tires. Even minor abrasions on the sidewalls could mean junk tires. I can drive over nails and gravel all day with the LT's and never have a problem.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.

      Actual Full Screen CarPlay on Refreshed Silverado/Sierras.

      Im in the same boat. Carlink adapter comes tomorrow and dev account is in process. Would you he able to send the new instructions my way also? Question, do you have to change code and republish app everytime developer updates? Thanks for your assistance, truly the only thing i cant stand about my truck is the carplay limitation

      Weight limit in bed

      By rav3 · Posted

      And Google AI says......... Yes, your truck can technically handle it, but you will be right at or near its maximum limit. A 2016 Chevrolet Silverado 1500 High Country with a 6.5-foot bed has a maximum payload capacity of approximately 1,770 pounds.Weight RealitiesLoad weight: Half a cord of dry hardwood weighs roughly 1,100 to 1,500 pounds depending on the wood type (like oak or hickory).Payload limit: Payload includes the weight of the wood, you, any passengers, and a full tank of gas.The math: If you weigh 200 pounds and have a full tank of gas, a 1,500-pound load of wood puts you right at that 1,770-pound ceiling.Safety TipsCheck the yellow and white sticker on your driver-side door jamb for your truck's exact payload number, as high-end luxury trims with extra features have slightly lower capacities than basic trucks.Expect the rear end to sag noticeably.Drive carefully, avoid sudden turns or stops, and keep speeds low if you have to travel a distance.
