old Mtr's only way to go! New style looks gay at first but when i seen them in person they look all right. not sure how they will perform but i have been rocking the crap out of my old ones and they are straight bad ass and take it..... i got a deep slice in one of them this year finally and it has not tore out yet and the slice is bout all the way through!!! kinda scary mobb n around wit it so i am looking for a good one so i can make it a spare!! So if the new one hold s up to be a good tire i might get a set. cause the rocks around here are sharp and jagged and will make a good day a bad day just like that bam!!
