Which are beefier?? BFG km2's or the iRok - 37's

 

Iroks definately are more aggressive. I haven't looked at the KM2's in person,so I can't say which is beefier, but if I had to guess I'd say the IROK's. The KM2's look like they'd be a better all-around tire (i.e. more street friendly, but maybe not as aggressive offroad).

They both seem to be great tires, it just depends on your needs.
