Im in need of new tyres and would like to give the Yokohama ad08R tyres a go. However I found the front R versions whereas everywhere I checked in the uk only have the older ad08 tyres. Is it advisable to mix the two. I thought that since the rear won't last as long I can get the R versions for the back next time round 
What are your thoughts? I was also checking for michelin pilot super sport but also couldn't find the rear size. Still undecided whether I should get the yoka or the Michelin. I was offered the Michelin ps2 instead but read these are older or the Goodyear f1 asym 2 instead.
Any comments would be greatly appreciated
Thanks
