I got Pilot Road 2s front and back installed yesterday at Bike Plus (internet tyres). Picked up the bike yesterday in a bit of a rush, rode home @60km/h.. no dramas. When I got home I realized the weights on rim were in the same positions and with the same amounts. I thought maybe coincidentally that it was exactly the same as the old tyre (fat chance). Anyway, this morning riding on the freeway at 100km/h and the bikes rattling my bones. The damn thing is out of balance. Probably both front and back. Now I'll go home and balance them myself. Same thing happened when I installed a rear tyre in December 2011 at a different shop. To be fair, I saw the guy try to balance them but didn't do a good job, started to shake again at ~85-90km/h. Got home and balanced them myself. Now, here is my question... Is it an 'extra' service to get the tyres balanced when installed? Do I have to tell him, "please balance my tyres"? Isn't it part of the service of installing a tyre? Anyone experience the same thing?
