in the mud... the worst tire ive ever seen
on the rocks..only a stock street tire could be worse
... I had a buddy get stuck in my yard with thrornbirds..wet grass and a 2 foot hole stopped the 33" thornbirds cold.
they are the WORST tires ever made.. they wear quickly, offer NO traction and stil have all the bad characteristics of a heavy mud tire (including flat spots and price)
just look around.. have you ever seen anyone ctually running thornbirds that has been wheeling for more that a year?
