So I have put about 2k miles on them so far (assume about 20% dirt roads) and compare them to Tourance and Tourance Next that I have been riding on almost exclusively for several 10k miles. I am doing a tire life expectancy spreadsheet since a while. I started that in hopes of finding a 10k+ tire that will last for a round trip to the Pacific north west. Who knows now when that can be done but I still keep evaluating my tires. Two differences right away.
One is thread depth front and rear. Rear depth comparison:
Tourance: 8.8 mm; Tourance Next: 8 mm
Mission: 11 mm. I failed to measure when they were new. The reading was 10 mm after 1k miles so I assume new about 11 mm. This is significantly deeper thread and hopefully will translate in more miles, as reported by others (if I can keep my right hand under control).
The other one is cornering on blacktop. The Tourances were like driving on rails when leaned over. The Missions want to "fall into" corners. Can't describe it any better but they give me a little twitchy feedback. Not scary but just not as neutral as the Tourances were. I ride 38/42 PSI F/R
So The Good:
Deep thread, not only in center but all around!
Good traction on gravel, pebbles, dirt roads. Much better than Tourance.
Solid performance on dry blacktop.
Assume similar on wet blacktop but I have not pushed them hard so far in the rain, so not sure about it.
The Bad:
Front Tire hum at 40-60 mph, louder when decelerating. Much louder than Tourance
Scary on wet clay/ bentonite dirt roads, little sideways traction.
Not neutral cornering behavior
