It was either 7/8 or 13/16th.... Cant remember. I think I torqued mine to 150 LB #.
Put some anti size on the threads and the mating surfaces of the rim to rotor (that is if you take them off) and between both rims in the back (If you having fun). Otherwised at least lube the treads of the lug nuts to prevent rust and make it easier to take off in the future.
I purchased a wheel lugnut wrench (the kind that has the 4 common sizes - look like an X) and a 3 foot steal pipe that slides over it. I dont plan on changing tires myself but I like to be prepaired incase I need to do the work myself.
It broke all of them loose just fine (always push down to break loose or tighen - lifting up can hurt your back). Then I re-torqued all the same (they were like 70 to 175 LB # from factory - wide range).
