The best rear tyre that I`ve used and still prefer , is a Mitas E09 140/17 Rear and a C19 Mitas front , for off road.
I use the same rear tyre always ,but change the front tyre for riding to work in the week with a Michalin Karoo 3 , awesome road holding , wet or dry tar roads/
And do all the tyre changes myself with my own Beadmasters.
