Hello. Looking to replace one rear tire on my wife's 600.  Only has about 78 miles but she took a chunk out of the side wall hitting a rock. Still Jill's air, but rather replace. I found a ia-8004 innova 25/10/12 on Amazon but I'm not sure if that is the stock tire. I'm not sure how to attach a picture here, but does anyone know the model number of the stock rear tire?
Thanks In advance

I had this happen to one of my atv tires so I took it to a tire shop where they revulcanized it and made it like new for a way cheaper amount than a new tire.
