I ran a Kumho on my Wing for a very long time and it did extremely well I wanted to play with other tires on the F6. I started off with a Bridgestone Potenza run flat in the 195/55-16, first off the run flats are really hard to mount! Such stiff side walls make for a stiff tire and the riding performance was so-so. Air pressure is super critical on the run flat to make it feel right (28psi) and maybe not all but the Bridgestone is a "groove tracker" and wants the bike to follow every rut and groove in the road, not bad but a little weird feeling. What made me pull it off was a problem I had when somehow I managed to get a section of rope wrapped up all around the swingarm and brake rotor, don't ask how cause I still don't know?? Anyway the 195/55 size tire will not come out the back without removing the left side muffler which left me along side the road with the bike in many pieces trying to get that damn rope out!

Next tire was a Goodyear Assurance fuel max size 175/60-16 and that tire is NOT a run flat. Went on the rim easy (after fighting the run flat off) and easily goes on and off the bike right out the back as intended. The Goodyear tracks the road well and needs more air pressure to not seem mushy, ended up at 41 psi. This tire does not track any ruts or grooves but the RPM's are a little higher all across the range (smaller diameter tire) and while this would be of great benefit to guy's towing trailers I did not much care for the slightly higher RPM's.

The 3rd tire I tried and seems to be the winner overall and the one i'm going to stick with is a Toyo Proxes non run flat size 185/60-16. This tire is hard to find as Toyo is the only company making one in this size (that I found). Awesome tire, tracks great and almost matches the stock tire size for the F6. The GPS and speedo are dead on. I think the RPM's might be a tiny bit lower across the range and not verified but I think my mileage is up? Tire pressure ended up at 41 psi on this tire as well and this tire will also go in and out the back for changing. This is my take on three different tires so take what you want from this and try what you like just be safe!
