I'm after 65K kms on two sets of RFT summer tires (let's say that 20% of this distance I rode with the winter tires, which an non-RFT Continentals TS790), staggered Dunlops, SP Sport 01 DSST. I do not see any problems with them, nor did I see that around 15K miles (or 25K kms) they would become noisier.

 

Well, I do carry around a huge nylon bag from the tire shop (they are using these when I change from winter to summer and back, to pack up the tires I replaced - I asked for one extra). It fits nicely under the carpet in the trunk and I get it out if I need to put on the spare and tuck the big wheel in the car.

Actually, I learned my lesson that even if you have RFTs it's not necessary/recommended to ride on a flat tire 100kms as I did (because I was too lazy and too tired to change the wheel). I am grateful that it was possible to go on a flat tire to my destination, but I ruined the RFT tire in the process. You should always change to the donut spare if/when possible.
