I am still struggling with choosing the right tire.

 

I am looking at all terrains. The lightest 33 inch AT I can find is actually the 295/65R18 Duratrac at 58 pounds. The Cooper ST Maxx, my second choice, is a 63 pound tire. The Toyo R/T tires, which are what I actually would like to get, are a whopping 71 pounds per tire for the 285/65R18 size.

 

How much is tire weight truly going to affect my performance and fuel economy? I am looking for first hand accounts from those who upped their tire size from the stock 265/65R18 to a 33 inch, LT rated AT tire.

 

The stock tires only weigh 41 pounds, so even if I went with the Duratracs, I am increasing my tire weight by almost 50%

I wouldn't really worry about the weight... I've found the weight doesn't really make a difference. My e rated tires are significantly heavier than the p metrics I had. However, no change in fuel mileage because I stuck with the stock size.

 

You'll find the larger diameter has much more of an effect than the added weight. Fuel economy = stock size tires.

i went from Goodyear A/T's to BFG A/T which are significantly heavier than stock and noticed very minimal difference in MPG.

Btw it's awesome that you still have the tag line "I've got an attractive woman burning down my house too darrick" :thumbs:

275/70/18 Duratrac is 55lbs. 33.2" tire.

 

275/70/18 Cooper ST Maxx is 56lbs. 33.39" tire.

 

275/70/18 Cooper Zeon LTZ is 55lbs. 33.2" tire.

 

275/70/18 Toyo Open Country A/T II is 51lbs. 33.2" tire.

 

275/70/18 BFG A/T ko2 is 58.2lbs. 33.2" tire.

 

The 295 width is what is killing the weight. You can get the height you want with the 275/70/18 and there is still a good tire availability, and cut down on the weight. And if you are running factory wheels (18x8) the 295 will balloon quite a bit vs the 275, being that there is more width to the tire vs. the bead seating. Better tire wear too.

The problem with 275/70 is tall narrow tires look awkward on a lifted truck.

 

The Cooper ST Maxx is out now. I have read numerous stories and heard one first person account of these tires being extremely dangerous on wet roads. Apparently they slip and slide all over the place, and lock up very easily. I live on the "wet coast", it rains here 7 months of the year, the very last tire I need is a tire that has terrible wet weather handling.

 

The Duratrac, well, I honestly don't feel the quality is there. It's an awesome tire, but I believe Toyo tires are made to a higher standard. Duratracs only get louder as they wear, and handling decreases significantly as they wear, almost to the point of being dangerous.

 

The only tire I can find that comes close to everything I am looking for, is the Toyo AT2. I wish they sold that in a true 33'', but the 32.6'' 285/65R18 will have to do. Talked to my local tire guy and he said you can tell a lot about the quality of a tire by how much it takes to balance it. They never have balancing problems with Toyo tires, and they take very very little weight to balance.

 

I might just say screw it and throw being sensible out the window. What I mean by that is, I may get the AT2 in 295/70R18 which is a 34.3'' tire, or I may opt for the heavier Toyo R/T in 285/65R18, as it's 32.8 inches and 11.50 wide.

 

I wonder how much of a difference the 295/70R18 would have on my power and economy? Probably a lot. It's damn near a 35 inch tire, the only saving grace is its closer to being a 34 and its 11.80 wide, but 12.50. I think height is better for fuel economy over width. Once you get a tall narrow tire up to speed, keeping it up to speed isnt such a big deal, and with a smaller contact patch, the resistance is less. Take a short, super wide tire and the huge resistance is always there, even once your up to speed.

That is what I have on mine. Looks pretty good with a level.

I went from the stock 265/65/18 Bridgestone duelers to 275/70/18 BFG A/T on a leveled set up...you can for sure feel the weight difference for this particular brand... not major but definitely not as quick of the light anymore.

My truck doesn't move at all doing 80 mph in torrential rains with BFG KO2s.  Excellent wet weather tread and they look great too.  Running stock size in a C-Ply to cut down on weight.  6 pounds heavier than stock each.  The truck felt like it had a converter and would not coast with E-Ply BFG Rugged Trails @ 50 lbs each.  It's now light and nimble and can pretty much go anywhere.

      AFM Experience

      By Grumpy Bear · Posted

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
