motorcycle tires problem

[Julio Cano]

The tires which I bought on ebay cannot be balanced, it’s out of round.Tried riding and had wobble. 
It was mounted in shop and they also put it on a rim they had sitting in the shop and same issue to confirm it.
Are they defective ?
They have brand new high quality tires for my  old suzuki gsxr750 and want about $600 for two tires.
Is it worth it to pay that much or buy another set of front rear tires like Hexautoparts which has good reviews on trustpilot.com?
Any recommendations ?
Thank you.

What brand and model are the tires? And as far as $600 for 2 tires, that sounds high. What kind of tires are they?

Is this a street bike ?

You could have just gotten a bad run of tires off the line.  It happens but the question is how many tires were made before they picked up on a production problem? 
Have you reached out to the vendor or checked any complaint reviews etc? 

I feel that one item you should never try to go cheap on  (especially street bikes) are the tires.   Its what the bike rides on and your life depends on when it comes to traction and stability.

Sounds like you got a defective tire if it's that far off balance
