New Tires for the 420

This past week, I bought some new tires for the old 420.  I'm not for certain, but I would venture to guess the old tires are the original tires - circa 1987 or so.  The tire size is 26-12-12.

I measured the tread depth of the old tires, and I measured 0.200 inches - right around 3/16 of an inch. 

The new tires are Carlisle Multi-Trac, and the depth is approximately 0.430 - about 7/16 of an inch.  That is a full 1/4 inch more!  Pretty amazing.

And they look real good mounted on the 420.  I expect much better traction, so I kept my wheel weights off.  That, and all my mole hills are pretty well mashed down anyways.
