Trail Boss Tire Size 20” wheels

[Sjordan]

What is the largest tire size I can fit on a factory height trail boss with factory 20” wheels? I have seen a lot about the 18” wheels but not anything about 20”.

A nice not too big and not small is 285/65/20

My buddy sent me this the other day, seems fitting... Can probably use this multiple times a day.

Aren't the stock tires basically 33s?

I just got 285/65R20 BFG KO2’s the real size is 34.5x11.5R20. I plan on putting them on the stock 20” wheels this weekend I don’t have a lift or leveling kit on my TrailBoss. I’ll post back if they rub and before and after pics.

This is the stock Wrangler TrailRunner275/60R20 (33x11R20)

This is with the BFGOODRICH KO2 285/65R20 (34.5x11.5R20)

 The BFGOODRICH 285/65R20 on the stock wheel and no leveling kit or lift kit at full lock I turned both left  and right and went forward and reverse in an uneven parking lot they don’t rub I can fit a nickel in between the tire and the mud flap they might rub in a little more of an off-road condition I will find out when I get a chance to go out.

Looks good! Those are the exact tires I was thinking about going to.  Slightly larger and more aggressive than stock.  The stock tires didn't handle too well in mud.

I did get a chance this weekend to put it through a little harder than pavement test and at full lock in reverse on very uneven ground they did rub just enough to hear them but nothing that was catching to much to need to do any modifications in my opinion.

I ordered the Motofab 1 1/2” lift for the TrailBoss Just in case they rubbed got it today and I’m not sure if I want to put it on or not with the little rub I have.
