re: batch problem
"you are right, that there has been a range Tourance-tires with some problems concerning shimmy. The reason of that was that the production tolerances were too wide. So we succeeded to reduce them to the less possible within the standards given. The tires were concerned to the DOT up to 2200. After then we changed the production as mentioned, and had no problems any more. So you can take a look at the DOT marked at the sidewall of your tire and compare."
So..check that Tourance!
