What size tires fit with a leveling kit on stock 20s

Hello, new to the forum here. I’m about to pull the trigger on a 2500 cc sb Laramie with the factory 20s. I’d like to level it and put larger tires on it. Will a 35” tire fit on the stockers with a level? Or will I need to stick to 33”? Thanks ahead of time!
 
The stock tires are 33.5. A 295/65r20 will fit just fine. That's a true 35x11.5. You might get slight rub on the control arm but you will never feel it.
 
I was wondering this as well, thanks for asking the question. Follow-up question to this, how would bigger tires effect towing, let’s say a fifth wheel? With 33s, or 35s. Contemplating upgrading wheels and tires on my mini-17 inch tradesmen setup.

I have 35s on 17x9 +20 offset with stock suspension and there is zero rub. These are essentially the same specs as your stock wheels. You should have no problems.

 
Stock wheels are closer to +45 offset. 295 or 12.5 wide tires will rub the control arms slightly on stock wheels. The +20 offset pushes them out enough to not rub.

Actually, 37x12.50s will barely rub with +20 offset wheels and that can be cleared will a box cutter to the plastic at the back of the wheel well.

Thanks for clarifying, for some reason I thought stock offset was +20.

Where are your pics with those new CJC Racelines? Did you see they just announced some 17x9 +20 CJC exclusive Methods?

I have 18x9 +18 Method Grids on my 2014 that I'm moving to my 2019 along with my Thuren coils and a set of new 37s.
 
So to clarify.. a 37” tire will not rub the control arm( just a trim-able plastic piece) on a 17” wheel but the 35” on the 20” wheel will rub the control arm? Or am I reading something wrong? Thanks for any clarification. I plan on having the level and tires installed by the dealer when I purchase the truck. I just want to have my ducks in a row. Thanks

Wheel diameter makes no difference with the control arm clearance. It's the offset combined with the tire width that makes the difference. When you push the wheel out an inch, the tire will no longer hit the control arm. +18-25mm offset is the best for overall clearance.

The overall tire diameter is what makes you have to trim the fender liner.

Here is a picture of the wheels and tires. Have to say that CJC Off-road was awesome to work with!!

Yes they are. I’ve ordered a ton of stuff from them. Their tech advice is off the charts as well.

Putting larger tires on lowers your final drive ratio. Increase tire diameter by 2", and your original tire size is 33", that's an extra 6% distance the truck moves for each engine revolution, which is a 6.1% reduction in the ratio. It's the equivalent of changing a 4.10 rear end to 3.85. That said, it's a fairly small change in performance for most towing. It doesn't really impact towing too much, unless you're pulling up more extreme grades or you've got extreme loads.

It can change handling slightly, you'll be sitting up slightly higher, your hitch is higher, but it's very small differences and some people don't notice them at all.

We need to see pics after that move! Sounds like it will look great!

Where can a guy see a pic of the CJC Method wheels?

And you're right, the guys at CJC and Carli both are great to work with.
I have just about everything Carli you can put on my 13 2500 and their stuff is amazing!
Just ordered a 19 3500 SRW and can't wait to start tweaking it.

I saw them on their Instagram channel. That's where they put all the cool stuff...
