I'm running 32's right now 255/75/17's, tires will need replacing soon, thinking of trying out 33's on aftermarket wheels...

 

Anyone with the 4.3 V6 running non-stock wheel/tire sizes?

 

Pics would be nice too :)

Unless you spend a mint changing your rear gears, you will have very little power. And if you do, you will get 8 mpg city.

 

Seriously, not trying to be an ass, but if you want to do that buy another truck. You will be better off in several ways.

33's is about as much as I would suggest you do. And even then your fuel mileage will suffer depending on what tire you choose eg. AT or MT tire

That's a great looking truck but I didn't see where he or she speaks about performance really. But did say 15ish mpg on a road trip. If that's hwy travel then in town mileage must really suck. Each to their own.

Alright just read that entire thread and must say again the lifted V-6 is efn sharp. Can't be to much of a slug cause one pic showed towing a medium sized boat.

I will concede that I am ignorant on the power of these new V6's. a76b06d537d7cc40315479ba18ffa81a.jpgSo if a lifted look like this is wanted, I say go for it!!!

I have 35 12.50 r 20 and get 14.5 city and can get as much as 19.5 on highway if flat land ..and somewhere around 15 to 16 if a lot of hills. People who say 8 r just guessing .. trucks says 14.6 now and that's about 85% city use..

The new V6's make damn near as much power as all prior 5.3/5.7's did and I've seen those run around with 10" lifts and 37's. did they gear them... I'm sure they did but not to lift just cuz he has a V6 is ridiculous.

Right now with my 255/75/17's i'm averaging 22-24mpg on the highway..According to tirerack.com , the tires that came with my truck were 36lbs, current tires are 41lbs, didn't notice that much of a drop in mpg or power loss...

 

Not quite sure people are aware of the hp/tq numbers of the new 4.3 V6 in the 2014-2015 Silverados..They make just as much as the V8's in the 2013 Silverados...And they make even more power on E85 :driving:

The new V6 is a better motor than the two it replaced, the 4.3 vortec V6 & the 4.8 Vortec v8...

I have the 4.3 and running 33s (305-55-20) with a 3" level average on Highway doing the math dividing miles driven on trip till gas tops off I get 15.5. On a good day no wind I get 17. Lowest I gotten was 11 towing a 16ft trailer with roughly 5k lbs for 50 miles. I've towed over what is rated, sure is not recommended but the the truck handle it like a champ. This v6 ain't no pony.

I have a 2014 V6 with stock wheels and tires and a 2.5 RV leveling kit and front air dam removed (both mods are supposed to affect mpg) and I still get 20-25mpg highway and 17-19mpg city. I highly doubt 33's will make much of a difference but as someone else has stated it also depends on the tire. If you get a toyo MT that weighs 60+ lbs that may be a different story but that will happen no matter what size your motor is.

    • Wawa and Meijer here have ethanol free (88 & 89) I use for my mower and lawn equipment.  Its not much more than reg.  I paid $3.29 a few weeks ago.  
    • tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.
    • NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.
    • That's interesting.   There was a factory wire-hole in the back, top of the rear cab, which had a wire for the third brakelight assembly running through it, as well as several holes (10 of them I believe) for all of the studs coming off of the 3rd brakelight assembly itself.   I sealed all of those holes with RTV/silicone as well.   I found it kind of odd, that none of those holes, were sealed with any kind of sealant by the factory - if there was any there, it wasn't very much.   That said, I've been out in heavy rain and have ran the truck through high-pressure car-washes a few times now and she has been 100% water-tight to this point.   I feel very confident in the repair, we'll see how it holds up.
    • I bought a used 2022 2500hd with 6.6L in February. In March took a 2200 mile trip towing our 6500 lb trailer. Changed the oil day before leaving and when we were arriving at our 1st destination, low oil light came on (roughly 1000 miles) it was 2 qts low. Now it towed like a dream, no issue there, and we did go through the mountains of TN, but still, 2 qts! Luckily I did purchase an extended warranty. Brought it to the dealership in April, oil change and consumption test. Brought it back last week, 1300 miles, no towing, and no oil showing on the dipstick. GM is reccomending a new engine (cheaper than them rebuilding), we'll see if the warranty company comes through.
