I have a couple of Duro knobby HF240 21-12.00-8 tires on order and have some questions... I'm new to all things Super Bronc 2 VT-1040 and ATV-style tire, are there any tips/tricks/step-by step procedures that I need to know regarding removing the wheels and bad tires from the super Bronc 2? I don't have a build sheet/manual for this, I've emailed Rick Chatten for the manual, but he's got to get some made up, so I'm flying blind in the meantime. Once the wheels are off the bike, is removing the old tires something best left for a tire store, or something that The avg. Joe can tackle on his own? Any helpful tips or advice is much appreciated! Thanks, in advance for your replies
