295- 65R20 on stock 2026 3500HD

It has the 6000lb front end.

Looks like enough room. Discount Tire says it does.

Any real world?

Has 275- 65R20 on it .

Thanks

I went with Nitto Terra Grappler G3

LT295-65R20 (35x11.50x20)

They fit with ease and look so much better than the 275-65-R20 Goodyear Wrangler Trailrunners.

Slight rub at full lock in reverse nothing to worry about and fixable. 

The speedometer is dead nuts on. GPS and phone.

It must be off from the factory. 

I was getting some pics and it started to pour rain. Pics tomorrow.

Some people will go a 2/1 lift (2 front 1 rear). Some will just crank the bars to level. Some do nothing (as in your case).

 

Good size for our trucks.

Yes I think it is the right size

The stock goodyear tires certainly don't have a very inspiring look from either the tread and/or pathetic tread depth as well as the plain looking sidewall near the tread area, they remind me of a space saver tire on steroids LOL. Never the less I doubt I will change the size of them as the stock size is easier to find and the fact that I will be running winter tires which are a lot harder yet to find in sizes that are non stock vehicle sized. 

 

Anyway your tires look nice on there and admire those wheels. What pressure have you been running in them so far and as I was curious about their added carry ability due to the increased size, I am guessing that unless you are packing a lot of weight in the cab or in the box, going off my trucks scaled weights you probably would be able to run down to the minimum pressure of 35 pounds for the LT tire type construction for both front and rear if you wanted to. Your tires for reference can carry slightly more weight at 35 psi then the factory size at 40 psi.

At some point I'll go that size and swap my stock 20s out for a set of black stock 20s. Maybe raise the front an inch or so.

Truck looks great, I'm considering the same size.  Can you elaborate on the rubbing in reverse at full lock?  Any pictures?  Where is it rubbing and have you done any trimming?  2024 3500 AT4 completely stock.  I tow a lot and don't want to lift or level or anything.  thanks.

I went ahead and gave it a shot.  295/65R20 Nitto Recon Grapplers. 2024 3500 AT4.  completely stock, no key turning or anything.  Just had to tie the fender liner back in a couple places.  No rubbing anywhere.
