I use the CrossMark on the rear, If you want a little better cornering in a Maxxis use a 2.1 Exception series Advantage in the front also the 2.1 Ignitor is ok. Run the cross mark in the rear with the ramps forward the same as you would on the front. IF you reverse it you do not gain any traction and your braking performance will suffer.Rex_Skidmore said:Yup. Either one in the front, with a great paddle tire in the rear for climbing/braking.
