If the rear tyre is less prone to picking up small sharp stones....then I will try them. Road 2s, 3s were great. 4s I liked less as the front moved a bit when pushing on, and rears, got sick of the regular punctures. Good enough for pegs down on the GS though.
So much choice for great road tyres now though. Roadsmart 3s. Conti Road 3s. Will just go with best price between the top brands when existing tyres wear down a bit more.
