Wild video, take a look and see these defective michelin tyres.
Did not notice that till I watched it again.....The wheel moves as well. I’d bet $20 he doesn’t have it centered properly on the machine. He’s certainly not using the lug holes on the outside.
A lot of tire mounting machines are available with a bead massage feature. Together with proper lubrication this should help to minimize vibrations due to mounting irregularities.
The person knows how to mount a tire, the tire is likely a defect.
It appears to the OP's youtube channel, so I suspect that's why he's being defensive.Actually, there are a number of things that I disagree with.
For one, he used the wire brush on both the wheel and the tire and didn't blow them off afterwards.
Second, he applied lube to the top rim flange BEFORE he took the tire off, wire brushed the wheel, then didn't reapply lube to the top rim flange just before mounting. To me this is the most critical part of prevention of damage to the tire.
I could go on. I am not saying that the tire isn't the source of the problem, but like most people, he misses a few things.
