Just installed the SmartTire system under new Metzlers (130/70HR18 front and 80/60HR16 rear) ... closely followed the manufactures recommendation for the install ...
I’m using the Parnes balancer. The rear tire took 30 grams to balance with the SmartTire sensor in place (normally takes 10 grams without the sensor on the wheel) ...
The front tire however took 80 grams (about 2.8 ounces) to balance with the SmartTire sensor in place (normally takes 20 grams without the sensor) ... I demounted the tire threes times and moved the light spot on the tire here and there relative to the heavy spot on the wheel to see what would happen. Using SmartTire's install recommendations exactly, the light spot on the installed (front) tire was smack in the middle of a spoke .. yuk! ... I demounted again and shifted the tire a little to get some place to install the weights ... (I'm using the OEM weights)
What do you think? Is 80 grams (two 30's + one 20) for the front tire within or way out of the ball park?
