The Black Lab transport vehicle just reached 57000 miles and it had it first repair.

New tires, because some idiot (me) manage to drive over screws that destroyed
two tires So..

If you are replacing 2, why not just do 4 given the tires had nearly 60000 miles on
them.

The "lab mobile" is X3 in which the back seat is always folded down to carry
three large labs!
