Anyone with experience running both these tires? I'm concerned with running the 315 BFG which has a width of 12.1" vs. the A7's 11.8". I know others have run the Hoosier in 315 square but will that extra width mean trouble up front? I have 3mm, 10mm and 15mm spacers but I don't want to get the tires delivered only to find I can't fit them. Do I need more than 15mm? I do have the ARP studs.
