My 2011 Chevy Silverado 2500hd

[r6realtor]

Figured I would start an actual thread on the forum instead of continuing to post on the other one.

 

I let my wife drive it today because she was going to be running around town all day, she said so far its averaging 14.4mpg, so far thats pretty good for nothing but stop and go, im sure it will go down and average out?? Maybe, maybe not??? my other truck got 13mpg so 14 would be an improvement!! I have the tires at 77psi and it still rides like a caddy. When I got it they had 50psi in them and it was only getting 13average, the tire pressure is definitely making a difference.

Jeez, I run my tires at 35 psi, but those rims look pretty good. For a fatory rim anyway. I like them much better than the old 8 lug gm wheels they used forever, I hated them. Got rid of em' before I even drove my truck.

The tires say 80psi cold, my brother(from another mother) owns a 4x4 shop and all his tire reps tell him to go by what the tire says for maximum wear not the sticker on the door which is more for comfort, I have only driven it for about an hour and thought it was still very very comfortable, my wife says beside feeling much more powerfull is feel almost identical to her 2010 tahoe, she said its not as "squishy as my tahoe" but it rides really nice! So far im really happy with it, the back up camera is so awesome, I cant wait to hook up my trailer to it and use the camera.

Very nice truck.i really like that front end, good luck

The tire pressures on the door placards were spec'd to the factory installed tires for the best ride, wear and fuel mileage. Keep in mind that GM is the only vehicle manufacture that spends billions of dollars testing and spec'ing

tires for their vehicles, on the engineering level.

 

I always go by the placard and adjust from there for wear, as needed.

I will have to look and even see what it says, I just have always gone by the tires themselves as thats what the reps at goodyear, toyo, mickey thompson etc... have said to my brother to help avoid lawsuits for an under inflated blowout. I do know that with that particular rated tire that you cant run them under 60-65psi or risk a super sweet explosion! It will be interesting to see what the placecard says once I get home, but so far it rides great even at that high of psi. Overall the wife seems to be real happy with it and since i have only driven for an hour, I loved it for an hour!

Well, you gotta update your sig pic and go drive it some more.

Just a note ran my 2008 2500 at recomended 70 psi and balded the middle of the rear tires in 2000 miles, lowered them to 55 all around and got 30000 miles out of oem tires

[r6realtor]

did you ever rotate them, thats weird, they last longer TYPICALLY closer to manufactures specs, but I suppose that does make sence since there is usually less weight in the rear than the front.

No offense but I've been in the automotive repair industry for over 15 years and I've never been told that you can't run a 10 ply/load range e tire under 60 psi because you'll have a blow out. GM HD trucks have been placarded for 55 psi sense they came out for the front tires and all of the 245 tire'd HD trucks were shipped with 10 ply/load range e tires. Maybe I've never met the right person or I have been getting bunk information too but......

 

I usually, with the customers written approval, will set HD tires to no more than 60 psi all the way around unless they are towing heavy loads. It is then that I have them crank the rears up to 80 psi as stated on the placard. 50-55 psi all the way around usually nets the best overall tire wear when they are unloaded. TPM trucks are a different story of course.

BTW, I too agree with driving it more. If I had that truck, I'd be driving it non-stop!

Hey no offense taken, just relaying info thats all, definitely not a tire expert for sure, maybe the 265/60/20 are a bit different??? I got to tell ya when I got the truck they were 60front right, 69front left, and 51-52 in the rear so??? who knows.

I run just what you are recommending and have been quite happy with it. And no blowouts after a year.

[Ezrider_92356]

i normally run 60 fronts and 80 rears. i tow heavy trailers and haul heavy loads tires are rated at there max load rating at there max psi more psi does not give you more load carry capacity on your tires but less can cause tires to build excessive heat and cause a blow out when hauling heavy. rotating your tires often gives you the best tire wear.

Wow, it sounds like the dealer failed hardcore on the PDI (pre-delivery inspection). Those tire pressures should have been set to the placard spec. Low tire light must have been on too.

 

Might want to take a peak around and underneath it, for other possible PDI misses, when you get a chance too. Nothing I hate more than tech's who skimp out on the PDI.
