The ride seems a bit hard. Could it be because of the nitrogen used to inflate them?

The best M&S tire for mountain use, for summer and heavy snow in the winter.

Have been on my expedition for about 40,000 miles and only look half worn

I bought this set of tires and did not take them off until they had over 96 thousand miles on them.

Best tires I have ever owned.

THEY WEAR SLOW AND DONT SLIDE IN THE RAIN LIKE OTHER TOP BRAND TIRES.

Wears good and runs quite.

The best tire on the road by fare love them

Might be the smoothest ride I’ve had.

Wear milage was excellent
