I am just wondering how the rockwell's hold up to 52".I have a buddy that is buying some this weekend and he is trying to decide on the tires.He can not afford the 49" Irok's so he will be running the micheln's or something of that nature.He has a 4 seater buggy and a bone stock 302 in it and a auto tranny.The motor is maybe 200hp...thx for any info or suggextions what size to run
