Dude... maybe he likes his Maxxis tires are better then the Animal tires, maybe he likes not getting plowed over by cars, and maybe he doesn't like to grind and doesn't want the extra weight
new & lighter maxxis tires (440grams each) are soon to be ordered, peg wise when i have some money they will be brought & the break wont be on long, ill get bored of it after a few weeks.
