I hate this crappy Kalifornia groovy concrete paving, as if in here it rains a lot to justify it.
On my last trip to Yellowstone/Bryce Canyon and detours I have never found this kind of pavement anywhere.
At the moment I'm running Avon Road Runner cause everyone else seems to like it, but next time I will opt for something else, with no longitudinal threads.

Have you tried different tire pressures to see if it helps any ?
The Continental 'Twins' tires that came with the bike, RB2 front, and K112 rear, were not happy with grooved pavement, the Metzeler Lasertecs don't seem to be quite as prone to getting 'nervous' on this kind of pavement, I'm running around 40 psi front and back .
Also, if you have an incident on grooved concrete, it abrades away flesh and bone at a higher rate as well .
-
The only time they do it here in Oregon is to prepare to apply a layer of new pavement. I guess it makes the two layers bind together better. It doesn't really bother me, I use Spitfires and Avon Roadriders. I don't try to corner fast on it or anything.

There is only about 2 miles worth of that stuff here in Lexington but I have to ride on it occasionally.....feels like grease on glass.

40 psi is a pressure I have not tried yet, without going in the garage I think I'm running on 32/ 36 psi
Will give it a try and let you know
Grazie,

Try the Michelin Macadams or the Metzler Lasertec. The diagonals on the front tires seem to do the best when it comes to rain grooves. I prefere the French tires. I think they are the best in this regard. (Oh nooooooo another ADOT).
-
the bridgestone battlax tires on mine give a minor headshake on the rain grooves, especially at interstate speeds. annoying but so far manageable. i'm running the tires at the recommended 32/36.
the suspension on my bike is set up pretty stiff too, so once i get some stuff rebuilt i'm hoping things will settle down a bit.

Hmm Actually, I think the BT45 tires on my R65 exhibit much less wiggle/wobble on the scarified pavement than the Metzlers did. I think that the metzler front tire tends to have more longitudinal lines in it even with the "block" style tread than the smoother, more modern style groove pattern in the BT45s. I DO know that I hit ALOT of construction and scarified pavement going to/from Tennessee back in July, and it wasn't bad at all. I run my front & rear tires @ 35 PSI.
-
Similar experience - my R65 with BT45s seems to have less headshake than my R75/6 with Metzler ME33s. YMMV
-
i don't remember what the stock metzlers were on my f650, but they were fairly nasty in a lot of conditions. bouncy, headshake, wore quickly, less-than-confidence inspiring in the wet...
i was never so happy to burn up a set of tires. ;D
-
Then try the Macadams. I really like 'em. Rock steady on grooves and crossing longitudial lines.
The Metzlers were always slow to warm up anyway unless I was on the Comp K. Too bad you can't get those anymore!
TTFN,
