Scooter Parts Palace TIRE & TUBE PACKAGE Razor Dirt Bike MX350 MX400 12-1/2 x 2.75 (12.5 x 2.75)

Does this come with a tube protector to cover end of spokes inside the wheel? Or is it even required?

My son's front wheel on his MX350 Razor is shot. My husband says he needs a new tube. Can I just order this and replace the whole front tire? Thanks in advance!

Will this tire fit with replacement of 12 1/2 x 2 1/4 in. (62-203) rim?

I this also compatible for the rear wheel on the MX650 ?
