Do they rub at all?

The very slightest of contact at full lock - only on the outer shoulder of the front tire against the liner; the rear clears with room to spare.  I expect I will be able to pin the liner back with a zip tie if I decide it needs to be addressed.

 

I don't know if I'll bother, it just barely, barely touches.  Hell, it may not be touching after the drive home and the suspension has had a chance to settle back to it's normal position.  I couldn't hear any rubbing while backing into my garage, which requires a full lock left turn as I approach, and a full lock right turn backing in.

Looks awesome. I get confused with the wheel offset stuff. I want to keep stock rims and do these exact tires. What would be the difference in that and your setup? More of a chance of rubbing or no difference?? Thanks

stocks rims would have less chance to rub

i have fuel with +20 also and hate to hear they rub . i have the stock tires on now. going  in and out of farm fields would surely rub then i would guess.

Offset is the location of the mounted area of the rim.  0 offset would be dead center of the rim.  Positive offset moves the mounted area of the wheel towards the outside edge.  Negative offset moves the mounted area of the rim towards the inside edge.  Offset is measured in mm.  By mounted area, I'm referring the the part of the rim where the lug stud holes are drilled.

 

Factory wheels are +47 for our trucks.  The ones I put on are +20.  The difference being 27mm LESS positive offset, so it moves the wheel outwards 27mm, which is about 1".

 

With the stock wheels, you shouldn't have any rubbing.  @Powerhaulic is running 296/65/20 Michelin Defenders (I think) on stock wheels, with no rubbing.

I just went and checked to see how much contact there is, now that it's daytime and I can actually see.

 

There is very slight contact with the liner at full lock.  It can easily be fixed by piercing two very small holes/slits, threading a black zip tie through, and then fastening it around the lower valance support rod.  There is enough flex in the liner to comfortably achieve the necessary clearance to not rub.

 

As the liner goes upwards, the amount of space grows between it and the tire.  Your concern about rubbing while in the fields is warranted, but you'd need to decide how much time you spend at full lock turns with a fully compressed front suspension.  It might be that it would be pretty infrequent to articulate that much while the wheel is fully turned.

 

As far as rubbing any other place in the steering movement, there is plenty of clearance to allow for articulation.

 

Also keep in mind, this is all on stock suspension.  If one wanted to, the keys could probably be adjusted 2-3 turns to remedy this issue, and not be extreme.  I did 5-6 turns on my 2018.  The ride wasn't bad at all, but it wasn't stock either.  With the additional height of the 2020, I've decided that I prefer not to raise the front.  Later today I'll give the liners the zip tie treatment.  I'm just glad there's no rubbing on the mudflap area.

thanks for info cdh7917 . I had last duramax leveled ,UCA and cut metal and still rubbed . I hated that . I may choose to go with 295/65  when these wear out and maybe turn keys a little -

As a side note to this, I think the GMC might have a tad more room than the Chevy based on the comments I’ve read.  I have +20 XD rims 20” with 285/65/20 Nitto G2’s and they just barely touch at full lock in reverse.  On the GMC it sounds like the 295’s fit the same way the 285’s fit the Chevy.  My truck is stock so a slight raise of the front would help but I prefer to leave this one alone.

Seems to me, I dunno, but with the crazy shape of the GMC wheel well, it looks to have less clearance then a Chevy, again, I don't know.

I know I have posted this before, but because the last couple people have been talking about GMCs vs Chevys and +20 offset wheels I thought I'd post again. 

 

My tires are 35x12.5r18 BFG AT KO2s on Method NV HD 18x9 +18. No rub whatsoever at full lock in and out of my steep rough entrance into my farm fields over furrows and such. 

 

Yes I know its dirty!

Had the truck detailed, paint decontaminated, buffed, polished and ceramic coated. A crew worked on it for 3 days. Paint is looking flawless!

Can a moderator "sticky" this thread so I can slobber on my keyboard, trying not to trade my 2015 HD. :)

    • If one can't be found, a good automotive upholstery shop should be able to replace/sew in a new panel where the damage is on the old cover. It might not be the cheapest option..
    • Does your dealer charge you for the tire rotation on top of the oil change price ?. I haven't had any service work done at my dealer yet other than when I brought it back soon after owning it to have the front end aligned to correct the steering wheel being off center a bit. Oh they called me at least twice hounding me to bring it in for an oil change and pushing a 300.00 package of oil change and tire rotation and whatever other quick simplistic checks they would do. Only going off of what a friend gets charged for his half ton for the basic oil change and its the same amount of oil as the L8T holds, it was about 150.00. Once one buys a set of tires from most shops these days or so I believe, they will do free tire rotations and some do free tire balancing as well as free tire repairs.    Certainly doing a tire rotation is no five minute job, and definitely not at home but because I run a set of winter tires on their own wheels, I swap them at home and its a one tire at a time deal because of the tire season swap although I jack up the rear and do it and drop it back down and then raise the front and do them and coordinate the tire rotation into that process for both sets of tires. I am using a floor jack though and if I need to raise both ends at once I use a couple sets of jack stands to have all four tires off the ground. I use either an air impact or battery impact and have electric impact as well so no shortage there of easy methods to spin the lug nuts, and then retorquing the lug nuts. None of it goes quick though but my wages are cheap though ... zero. I live an hour out of town, its easier just to do things like that myself than waste a bunch of time in town and having to make an appointment and probably a special trip and sit there at the tire shop waiting for them to get my vehicle in and get it done and not screw something up in the process. 
    • I do have the 8 speed.  Interestingly enough, after driving my truck for the past 2 days now, I have not had the clunking issue at all!  I am beginning to think it may have been suspension/leaf spring related, and somehow when the shop put my truck on the lift to do their initial inspection, it relieved some built up tension/pressure that was causing my problem.  I swear it felt I was a bull rider on a bucking bull the way the truck would almost rock back and forth slightly before the big thud/clunk when coming to a stop.  I am hoping I got lucky here and it's gone for good.
    • Bring it to discount tire. They do free rotations even if you didn’t buy your tires there. I didn’t believe it until I tried and they did. You can tip the employee if you would like 
    • Best part of this video is how it resets expectations. Wonderfully done piece. It also made clear a few points I've made from day one. Detergent oils DO NOT KEEP A MOTOR CLEAN at the recommended or longer change intervals. They just get dirty slower than a non-detergent oil and there isn't spits difference between them on this point if they carry the DEXOS license. Great thing about the license that gets missed is it assures CONFORMITY even it that means a low bar.    One thing he did not talk about that I paused on an magnified was the condition of the oil ring separator. Besides a stuck ring a plugged separator and land drain back is huge when it comes control. We see in short order improvement in control IF that is the problem.    Another item I took exception to and he did not make plain was the condition of the timing chest and under valve cover having something to do with indicating piston cleanliness. Schaeffer's Oil makes that same omission in their million mile Ford video. I'm guessing he has never torn down a Red Line HP, AMSOIL SS motor that has been on that diet from the get. What he showed in the video was a good deal of varnish. Something totally absent in Peppers 165K cover off look. I smiled because he did his at the same milage.    He also makes the mistake of assuming oil temperatures in the pan are the temperature all over the motor even though he makes note of the piston being the hottest part of the engine. that baffled me a bit.    I can tell you from personal experience and witnessing teardowns of family motors that even oils of the 1960's would keep them squeaky clean when OCI's were 1500 to 2000 miles without exception. At 3K and above you get what he experienced and the longer you leave it the quicker to gets to the junkyard.    I think his is missing a opportunity not tearing it down again when he's done killing it. Time would be his only cost.
