I am considering maybe going with a set of 33x13.5x18 Interco Irok radials here in the next year. I was considering a set of regular M/T's but the irok radials are cheaper than most M/T's. The thing is though is i'm trying to find out if they wear down as fast as the other swamper lineup of tires and are they extremely noisy? does anybody have them mounted now or had past experience with them and what kind of mileage did you get out of them and how noisy were they? i'm assuming that with good care (rotating and proper pressure) on a titan that a set of regular M/T's could last 40k miles or so, am i right? thank you for any help.
