Put 40psi in it and see never had a problem out of a 709 even when its worn out.Just had a new 709 mounted on a 2010 and now have a wobble at 25 to 30 mph...Is this common for this tire..I'm running 36 psi..Never had a wobble with the stock Dunlops..Maybe a little more air ???
glennuk, wait until you get a few miles on that tire (Metzler me880 tyre) and report back that you don't have any wobble. I have never had a tank slapper on the wing, but the closest I been to it is when I was coasting downhill (about 45 mph) when my headset cable came loose. I let go of the handle bars long enough to re-attach it and it was a hand full trying to smooth out the shake. Tire had about 5000 miles on it and was very near its end of life..... .but the metzeler me880 marathon glx is also an excellent tyre and when my rear one is gone i will replace it with a metzerler.
