Hi All - New to the forum, coming from a '17 Ford F-150 that was leveled and running 34" tires on stock wheels. I have a '20 1500 RST with the 3.0 Duramax. Looking to level the truck and add new wheel/tires immediately. Currently have 265/65/R18 with +26 back spacing. Going with GM AT4 stock wheels with +24 backspacing with 285/70R18's. Anyone running something similar that can offer some insight prior to pulling the trigger on the wheels/tires? 

 

Attached I have compared the two setups and I think I will be in the clear. Just considering the obvious questions: caliper clearance, Control arm Clearance, Tire/wheel fender. Any comments would be greatly appreciated.

There arent alot of options in 285/70, 285/65 or 295/70 gives you alot more options. There are some guys on here with 295/70R18s on stock trailboss trucks which is a 2" lift

I have 265/70 ridge grappler on order and fuel Anza 18x9 wheels. Tallest tire for an 18" wheel i could find that isn't 10 ply.

I have 275/70 on my Ram stock height and its a nice tire but 10 ply does make the ride a little more harsh especially off road, on highway it's not too bad if the roads you dive are in good shape.

Gotcha - appreciate the heads up. I ran 275/65R20 on my Ford and those were 10 ply - definitely a harsher ride but I liked how the sidewall didn't compress. Nonetheless just talked with a local shop and bought the 285/70R18's. If I remember, I'll post some pic's after I get everything installed.

      The Peckish Synapse

      If it has a stick I can have fun with it. When my wife first got her Acura years ago I used to tease her about it. I was only interested in muscle cars. They’re gone now. So once a month I drive the Acura. Every once in a while I’ll take it to Redline. But just normal driving on some twisty back roads usually does the trick.

      2010 Avalanche 5.3 not running correctly after engine swap.

      By contrabombarde · Posted

      I went through again with a test light and everything checked out.    I suppose it could be the MAF itself but I've tried 3 different sensors, 2 of which were in running vehicles previously (the one in this truck, and the one in the donor truck), as well as a new one I picked up from NAPA. I would just be surprised if all 3 were bad.   EDIT/UPDATE: I swapped in the MAP sensor that was originally with the 2010 PCM, that made the code for map sensor voltage high Go away, and the map sensor seems to read normal with key on engine off (14psi or so), but it still doesn't run and does the same thing as before.

      No Software Updates - Old Build

      By Atlas · Posted

      In addition to a cell or wifi connection, the infotainment needs to be enabled to download software updates. That's a toggle within the system settings.   But...if the truck was prevented from receiving updates in a past life, missing a bunch of updates may mean it won't go back and download all of those because they're not available or the system is too far out of date.   If a formal recall depends on a software update, the recall for that truck remains in an open status until it's applied. The dealer would need to apply the software update in that instance.   Most updates downloaded and applied via the infotainment aren't recalls/safety recalls, they're enhancements and usability fixes which aren't critical.

      Brake Pad Warning Message

      By Vu1can · Posted

      Recently I've been getting a message, "New Brake Pads Detected. Reset Brake Pad Life?", But I haven't had the pads replaced and the truck only has 28,000 miles. The Brake Pad Life shows Front 64% and Rear 79%. I select NO to resetting the brake pad life and the message goes away but comes back at the nest restart.   I stopped by the dealer and was told that it sounds like a software glitch that would require reprogramming. Even though I have the extended warranty, they tell me that reprogramming is not covered unless a module was actually bad and needed to be replaced. Simply reprogramming is not covered. So, they want $200.00 just to diagnose the problem. If it turns out no bad module, another charge on top of that to do the reprogramming. If the cause was an actual bad module, everything would be covered under the warranty.   Just wondering if anyone else has had this problem. Should this issue be covered under the warranty?   Thanks

      NHT is diesel only, correct.     The GVWRs for NHT on 3/4 ton bring them to the same numbers as many of the 2WD 1 tons.  A crew 4x4 standard 3/4 with NHT is 11,750lbs, a 1 ton same cab/box/4x4 is 12,100lbs.     Hubs and hub bearings are the same for 11.5" and 12" axles.  Housing, diff carrier and ring/pinion are larger for the 12".   All gas use the 11.5" axle, 3/4, 1 ton and 1 ton DRW.
