Zilla tires, actual measurements, 4 sizes.
 

Here are the two bikes, green one has s/w 27s, and the yellow one has s/w 28s. Aired to 6/8psi, both sets mounted on ITP wheels.

Those look unstoppable.

Those are great tires. :tup: How much did they cost, and where did you get them?

I just ordered a set of ITP mega mayhem for the UTV at work. 27"
