Hello all,

I've read many threads on this forum and others regarding tires/wheels for the L5P HDs. I've got my options sorted out to a few choices and was hoping for some additional advice. I did some searching on this but really haven't come across anything that cleared up my questions.

My plans are as follows:

  • Level front of the truck by going 7-8 turns on stock keys
  • *Possible* 1" block in the rear (most likely not)
  • 20x9 +1 offset wheels


I have been looking at the below tire sizes in a Nitto Terra Grappler G2:

  • 295/60/20 (preferred)
  • 285/65/20 (rubbing expected)
  • 35 x 11.50 (rubbing expected)


On my 14 Silverado 1500, I added a ReadyLift level with 3" rear blocks, Fuel Beast wheels (20x9 +1) and 295/60/20 Nitto Terra Grappler G2 tires. I had very slight rub in reverse but was able to reduce much of it with some careful trimming on the inside mount area of the mudflaps.

Has anyone run a set up like I'm considering and if so, did you have much rubbing?

Thank you!

I have a leveled 2500. I use factory wheels on 275/65-20 tires. No rubbing.08be2ca8ae6d47ec951a5bbcded759b8.jpg

There are guys running 35x11.50x20 and 285/65/20 with a level on stock rims. Those sizes on a 9" wide, +1 offset rim will make things interesting. I think it would be close, but might require a bit of trimming. The 295/60's should clear fairly easy though.

Thanks guys.  The 295/60 size that I had on my 14 Silverado 1500 worked pretty well, and I only trimmed the very inner edge of the mudflaps.  I am really leaning this direction because I like the overall diameter (~34") and the witch is pretty nice too at right around 11.75".

 

What are the stock wheel dimensions?  20x? +20 Offset?

 

I do not like the chrome wheels on the Denali that I have now, but maybe I'd consider something aftermarket that is close enough in size. 

 

Also, maybe a 275/65 would work?

Thanks, I didn't realize that the stock wheels were +44.  I could probably do a 20x9 +20 offset aftermarket wheel and not have any rubbing, and have just a little bit sticking past the fender. 

 

Too many choices...!

The more I think about this, and the more research I do, is giving me ideas to change my initial plans.

 

I'm thinking that a 20x9 +20 with 295/60 will be the combination I end up choosing.  Everything I'm reading is that this set up, when leveled, should fit like a glove.

 

Agree?

I think you’re going to be about the same size...but wider. Than what I have. I would let tire price decide between 275/65 and 295/60. I’m trying to measure out 295/65 on a 0 offset.

That should fit just fine. That tire size is fractions of an inch shorter, but wider than what I'm running...and my rims are 9" wide with +18mm offset. Mine clear easily, without any trimming at all.

Shorter than what?

When I measured +2” from my stock wheel and 275/65’s I was in the fender liner at about 1/2 turnin

Shorter than the tires on my truck. I was explaining that a 295/60/20 is slightly shorter, but slightly wider than the 285/75/17 that I'm running. And, he was looking at +20 offset rims, while mine are +18. So, in theory, his setup should fit...because mine does. I probably should have explained that better....

I had 20x9 +1 rims on my 2017 High Country with a leveling kit.  Biggest tire I could fit was a 285/55/20 that I thought looked too small.  I took off those rims and went back to the factory 20’s.  I put 275/65/20’s on the factory rims.  Personally I think the best look is 305/55/20 on a +18-+25 offset wheel.   I just can’t blow any more money on my wheel and tire addiction.  The 305’s on +20 will clear just fine

      Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

      By Policeoff01 · Posted

      Curious, did anyone ever get a fix for the vibration reported here.   I have a 2024 Silverado with 6.6 duramax.   I’m noting the same vibration resonating up through the steering shaft into the steering wheel.    Best way to describe- like someone is tapping on the steering shaft/components and it’s resonating into the steering wheel.    thanks.

      2015 Sierra Denali L86 cyl 5 misfire at idle

      By Gkistler · Posted

      Hi friends - first time poster. I have a 2015 sierra Denali with 150k miles, I’m the second owner and she’s given me 75k of great service. I run a pulse AFM disable device. Starting Thursday when I exited the freeway after a short local ride it started idling rough, with an obvious misfire shake and was down on low end power.  I got it home and hooked it up to my scannner and found no codes but in live data a pretty bad misfire on cylinder 5. I replaced the coil, plug and wire with all new OE replacements (Delphi gn10165 coil, acdelco wire and 41-168 plug). It’s still behaving the same way after firing the parts cannon at it.   I know cyl 5 is a non AFM cylinder so I am not thinking this is AFM related but I’m kinda at a loss. injector? Bent pushrod? It’s running too well over 1k rpm to suggest those IMO. Has anyone chase this issue before and what was it? Any suggestions?

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.
