For European leg Tourances are probably the best bang for the buck tires around. One of the longest lasting tarmac tires I know for DS bikes.

If you are looking for durability then don't buy the new Tourance EXP version though - they last considerably less than the original Tourance (non-EXP) which are still made because it's still a very popular tire (no wonder, since it really lasts - good for long distance tourers). And here in America I hear people almost have stopped buying the new Tourance EXP since they're dissaponted in them being used to the original Tourances.

I currently have EXP in the rear and the original older version Tourance in the front. Rear indeed wears too fast for my liking, but yet in the sharp corners the EXP does feel more planted while the front wants to wash away - and while most of the weight is in the rear. So the EXP seems to be kind of compromise tire - more grip with the cost of durability.

With fully loaded bike you don't go to road racing or footbeg scratching curves anyway, so original Tourance seems to make more sense in that case.

But yet if you go touring with a big money wallet and thus with a litte or no gear on the bike then I'd pick Tourance EXPs over the original Tourances tho - they are just more grippy tires and thus more fun in the corners with a lighter bike .
