Retarded Jumbo Kong Tires on a LST XXL Convert??

[Desert Rc]

I am very slowly putting a build together for my xxl that will have a castle 1520 installed. I was looking for some retarded Monster Truck style tires for her and came across someone that had some Jumbo Kongs for sale. They are HUGE!! Maybe to big. I value your guys opinion so if you say dont bother I will pass. I am not a huge IMEX fan but these tiress looks cool to me. Also I have a 17mm hex/nut conversion on the lst do you guys know what wheels will fit is it just a tmaxx size?? Any info/suggestions or pics of these would be really cool.
