Cant go far wrong with mt21s this time of year for a 50/50 tyre. Tkc 80s are another good dual purpose tyre. That saId if youre not ragging it on the road a Michelin enduro medium is good for nearly 2k new to shagged or Pirelli mt43 trials tyre.
10 days TET, so probably TKC80. I know Comp 3 and MT 43, used them for years, no chance of doing the distance.
Several out there, but approx £100 for a rear - ouch!
If needs be etc.
Don't use an mt 21rear. Great tyre on and off road, but they dont last very long. My ttr600 wore one out in 1000km in the Spanish pyrennese 2 years ago. The fronts are great tho.
Currently using a Mefo super explorer. That's done 2 trips to Spain now and still has a bit of life left in it.
