Stick with the original Tourances and don't believe the nonsense about Chinese manufacture. I have well over 100k on these tyres on various GSes and they perform brilliantly wet or dry. My one regret is I can't use them on my GSA LC.
Done untold miles on Tourance (originals) and never found the need to switch.
Same here, I get good mileage from them and usually get a pair for around 150 quid delivered, then 12 each to get them fitted, good in the dry, wet, motorway or mountain pass,
, had Roadtec 01 fitted yesterday at 23526m
