Since you asked, nothing says mall crawler like 20's on your TJ.
Here's a couple reasons. The 20" wheel tires won't perform as well off road and will cost much more than a smaller rim. You also need to research everything that needs to be done to your TJ to run 35's. It's way more than just a lift and new tires to do it right.
I appreciate the advise. I want to go bigger than a 15 though, what do you guys think about a 17? I'm not a big off-roader but, I would like to have the right setup incase I ever do.
17 is far more appropriate. 15 does have the most tire choices but you should look at the selection of tires for 16 or 17 wheels before making a decision. Another thing to consider with 35's is the need for bigger brakes (along with heavy duty steering components etc). You might need 16" wheels to clear some larger rotor/brake options.
What fits for you you should always research and do more research. I have learned there are offroad vehicles and some want mallkrawlers. There is nuthin' wrong with what you like. This is why mods are so awesome. Go with what makes you happy to wheel in road or mud.
OK now that you are speaking more reasonably about a 17 inch rim with 35. How bout we hear about what you already have done. There is a ton of mods to run 35s correctly and reliably. If you have a Dana 35 rear.... that ain't gonna work. You'll need a stronger rear axle and a better suited gear set. How about brakes. You may be able to make those wheels and tires roll, but you should worry more about stopping them. Since I may be on the same roads as you... Id rather you be able to stop them too. If you have a stock steering set up.... again not gonna work. Then you come to amount of lift and what equipment is installed on the TJ. As far as lift, I lean more towards LCG builds. 2 to 3 inches of lift with lets say MetalCloak or Gen Right fenders. You cant go wrong with building the Jeep the way you want to. You just need to do a lot more research into what it takes to do these mods and do them safely.
As for the pics of 20s on any TJ.... not many out there. 20s are more for flash than most TJs are willing to show.
