no it's not really the cost... i'd only need 2 anyway - i was just thinking that getting by the AEM rotors with the stock caliper hanging out a little further that 15's would be cuttin' it real close. i've already made the blunder of buying tires without really checking if it would work (smart) tires are 26 x 10 x 15 a little big as it is , but if i can get a rim for them i'd use 'em.
thanks
