RE: biggest wheels
I have seen the Jumbo Kongs on a E-Maxx.
If you want the worst looking tires that money can buy, then get them.
They look awful. At first when I saw them I thought that they were plastic, second they are way to big, third they are too heavy and bulky and will take down performance, and fourth at $100 for a set of 4 there would be no way that I would ever buy them.
I would rather spend $100 on beadlocks then buy the Jumbo Kongs.
But that is just my opinion.
