What I sent them.
Message: I have run many sets of your tires on both of my ST1300's from Z4's , Z6's to Me880's. I recently bought &; installed a set of Z8's. Right from the start there was a harmonic vibration that was not there before the new tires. I changed the rear wheel bearings &; the vibration was still there. Soon after I got a rear flat &; the rear Z8 was trash. After installing a new Z6 the vibration was gone! I chose a Z6 because there are more than a few stories on the St form that the Z8's cause type of vibration. To me this is unsafe &; would like to know if you have an explanation for this?? This tire had about 900 miles when trashed, I was ready to get it off of there any ways as it was driving me crazy. I am waiting to hear your response as I am sure this is not the first time you have had this complaint! Signed Loyal Customer For The Time Being! Kevin
What I got back.
Hello Sir
The Roadtec Z8 series has been out for a few years now and we have zero complaints from ST1300 riders and we of course sorry to hear that you have had a problem with your tire(s). We do strive to produce perfect products but with any type of manufacturing small anomalies/concerns will surface from time to time. And as your tire was punctured we wish we would have been able to work with your dealer before that event to get the tire back for an inspection. In the future please note new vehicle and tire manufacturers (auto, motorcycle, car, truck, and tire) rely on the local selling/installing dealer to sell and service your needs before, during, and after the sale so you are looked after in a timely manner. Thank you for feedback and we will archive the e-mail.
