Help me with tire size

[lucascole76]

I have a 2006 dodge mega cab 2500

I have a 2" level kit and 20 " wheels .

I was told the biggest tire I could fit under the truck without any rub was a 305/60/18 ?

Does that seem right? .... Anyone out there have my setup and was able to go bigger?

Thanks fellas

you can fit 275/65/20, 285/55/20, 285/60/20, and i think a 305/55/20

You can fit a 35" tall tire easily. Depending on the width and offset of your 20's you should have no problem fitting a 35x12.5x20.
I have 20x9 with (I believe -6mm offset) and 33x12.5x20 tires and they look small so I plan to go with a 35x12.5x20 eventually. I also have a 2" level.
