    Hot setup for 700XX rear tires - MX

    Everyone that owns a 700XX knows the biggest drawback when trying to MX the quad is, IT WONT TURN. The IRS just gets too much traction, plus it's next to impossible to run an 18" tire setup. We have found the solution. We are now running a set of Douglas front beadlocks size 10x6 (4" back spacing) with a set of old Armstrong Fast Trekker fronts sized 21x7x10. Essentially the tire is 19" tall when mounted. The narrow tire provides just the right amount of traction and the 700XX still comes out of the hole great, plus it can now be pitched sideways like a straight axle. This dramatically improved the handling of our 700XX on the MX track. It's very controllable and much funner to ride.

    These Tires are now made by Titan:

    I will put some pics up when I get a chance. Its only got minor mods right now: No airbox lid, baffle out of exhaust, 400EX nerf bars (AC), Douglas Ultimate Beadlocks up front with Quadcross MX Pro's, then the Fast Trekkers and 10x6 beadlocks on the rear.

    Best setup for MX is to get a set of ITP 10x7 or DWT 10x8 and put the ITP Holeshot 19x10x10 tires on. This is a good setup.
    Or order a set of Maxxis razr 18x10x10 or BKT X-drive 18x10x10 , both these tires are availible but hard to get a hold of.

    Because of the rims availible you will gain 1" in overall wheel diameter.

    That looks like it would have terrible forward bite.

    That first idea sounds good, got a pic?

    I've had those 18x10x10 tires before and they suck. Not enough sidewall and you'll destroy wheels left and right. The extra inch would help.
