Here is the quote from that website: "Do not use a tire on the road that has been subjected to motorcycle dynamometer testing. The stress from this process may result in tread compound degradation and possible tire failure."
...That's pretty much bullshit folks. Good advice is not to use race slicks/soft compound DOT tires for dyno time.... the drum is pretty abrasive and will pretty much waste/cold tear an otherwise useful track tire. A good street tire in good shape has nothing to fear from a few dyno pulls. 
Agreed. I have been hearing this statement forever.... I've been operating rear wheel/tire inertia dynos for over 30 years and 10's of thousands of runs on bikes up to 600 hp. I could name very extreme examples like running really big power turbo bikes that are on there way to LSR events, and run over 250 mph with the same tire that was just used to tune it on the dyno. But it's really just senseless on why they make these statements.... It is no different than running your bike on the road. Yes, the knurling on the dyno drum can leave some abrasion on the tire that is smoothed away within the first few miles of running it back on the street. The only time it may be an issue, is if the tire is under-inflated when running on the drum or the operator is making a 100 runs on your bike (although when I've been developing systems I've routinely made 60 - 100 runs with very minor wear impact on the tire). Most Dyno tuning sessions with a Tuning Link would be in the 5 - 20 run range. And at a "Dyno Shoot-out", it's probably 2 or 3 runs. Just not alot to make much of an impact. But if you were running your bike on the street with under-inflated tires and took it to the soft-limiter or speed-limiter, your issues would be potentially much greater since obviously your not in a static position (you are a missle along for the ride if god-for-bid something happens to that tire because of under-inflation....). If anything, I would opinion that it is less stressful, since you have a drum turning and "giving" much easier than on the pavement that does not "give". Sure we can pull it down with the retarder/brake, but again, very, very minor impact. It doesn't mean a Dyno operator can't make an impact on your tire if he wanted to, but hopefully those guys are few and far between..... I have yet to change out a tire because I felt the "stress" of the Dyno session exceeded an exceptable level.
