I have an '87 Vanagon 1/2 Camper (weekender). I just replaced some worn out
Vredestein Transport Steel with Michelin Agilis. Agilis had the highest
recommendation and therefore I went that route. After driving home over
mountain roads I discovered these tires don't have near the road handling
capability (more particularly cornering) as my worn out Vredesteins did.

As it turns out I purchased the Agilis 61. I did not realize at the time,
nor my tire dealer, that there are different models of the Agilis ie. 61 vs.
81. I am wondering if the 81 would provide greater lateral stiffness and
would it be a better tire in this regards. Or if the difference in cornering
is a result of going from an almost bald Vredestein with more of a summer
tread to the new Agilis with fresh all-season tread that would, I assume,
have some flex to it.

Any insight on this would be much appreciated.
