how big

thats a big tire. i had them on my 69 dart. on a 7" rim they are 10x29 mounted and aired up. they used to just rub the front edge of the wheel opening. rubbed the paint off but the tire showed no wear. i put 1/4" shim plates between the front spring hanger and the mount to move the axle back and it worked. i took them off and eventually went with 255 60s though.
