Largest tire I can safely put on my jk willys

ok so i have a 2016 jk willys that has stock suspension and stock rims (all stock). I am in need of new tires and as much as I would love to redo it all I also have a baby on the way. So, with that in mind I can change rims as long as they aren’t outrageous in price, but what is the safest largest tire I can put on? I ride on dirt a lot and pull my boat with it, outside of that i don’t have a lot except some street riding now. What do you guys think?

 

33s should be fine for what your plans are for the JK. Quality wheel spacers installed correctly will address any contact short of full articulation

 

With that being said thank you. What is a good tire and wheel spacers that I should use?

 

KO2s / Nittos are a good AT tire with an aggressive tread pattern with decent road manners. Quality 1.5” wheel spacers like G2 or Spidertrax should do the trick.

 

What’s the tire size on 33s? I’m really a noob in all of this

 

285/70R17 is approximately 32.7"
