2018 2500HD Tire Replacement/Upgrade

[cdh7917]

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.

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

+2 ?  Level, spacers?  You lost me!
