You mean being able to bully people who are responsible with their money and considerate of their fellow drivers isn’t a very good reason?
That probably doesn’t even register in my thought process one bit. I don’t care who bullies who. If the kid can pay for it himself let him buy the stupid thing and watch it eat up his money. If he has any brains whatsoever he’ll realize his mistake in about one or two weeks. Learn the hard way. Even tires on something like that are going to cost more for one tire than a set of 4 on a regular vehicle.
