Speed wobble and Heidenau K60s

Recently just switched to a pair of Heidenau K60s (yesterday) because I heard good things about them. Apparently you can't go over 65 mph on them... I've never had a speed wobble until today on I-25 in Colorado. I was riding how I always ride and the bike never felt secure below me above 65. I'm sitting here and I can still feel the constant wobble I got when passing our being passed by vehicles. At one point however I switched lanes and a bigger wobble formed and the bike started to wobble more and more and then the person in front of me put the brakes on and I had to go to the shoulder to ride it out.

I'm blaming the K60s because that's all that's changed on my bike. Is there anything else it could be? Bike feels fine at other speeds 70 and below.

I have to ride 1,500 miles home starting tomorrow and I am so not looking forward to it on these tyres.

Are they balanced? If so, did you use stick on weights or dyna beads?

I know somebody on a DL650 (not on this forum) who has experienced this the the K60's, but not other tires.

My brother has them on his GS. He loves them. I could not feel any wobble on his BMW up into the 75 - 80 mph range, but it has a completely unconventional front suspension.

Stick on weights, and yes balanced.

I just put the K60's on my 2009 dl650 , and have no such wobble , even up to very illegal speeds ( which I would never do , but if someone did , my tires didn't wobble ). The old , worn out tourances they replaced did show a pronounced decel wobble with hands off the bars , which I attributed to loose or worn steering stem bearings ( on the list for this winter ) , but the Heidi's are great .
Have you verified tire pressure ?
Could it be an issue with the bike heavily loaded with gear ?

I guess it's not impossible that you just got a bad tire ?

best of luck , Alex .

Not all my lucid moments are consecutive .

Bike is loaded with gear, was loaded with gear the past 3 weeks on the original OEM tyres as well which were perfect.

If they're bad I have nothing to replace them with and would have to ship them back to Revzilla I guess.

But I leave tomorrow morning for Canada... And mailing them from Canada would suck.

Is the front tire running the correct direction or maybe installed backwards?

Appears correct, however it was at 41 psi. I've adjusted that down to 33.
