I went today for a ride and about 25 into the ride (4 of which were in full speed on unpaved gravel trail) I noticed that my rear Kojak 406 has a severe bump (see pictures below). I was able to ride few more miles to my car without loosing air but it's time for a new tire.
Overall I am very happy with the Kojaks (have them for about 1500 miles, running them at 90psi). I have used them both on paved road and very rough gravel trails (especially after I switched to a full suspension bike which made me invincible) so Kojak is the natural choice but I am thinking maybe I should another model a try.
Having a low rolling resistance on smooth roads is a primary requirements though ride quality and durability on unpaved trails are also things to consider.
Any suggestion for alternative tire? How does the Marhathon Supreme compare with the Kojaks?
(BTW, I have Scorcher laying around but it too tight to fit on my rims).
