Acctually Im really suprised that the MTZ actually arent that loud compared to most mud tires. I got them cause I liked the way they looked and figured they would look sweet on my truck and the noise thing didnt come to me till after I bought them. I have rode in trucks with bfg mud terrains and some other mud tires and these are quiet compared to them. Im not saying they dont have no noise cause they do but I cant really notice it unless the radio is off and the window down. Ya I know what your talking about with the 18. I just bought a set of 17 classic II mickey thompson rims. Got the set of rims and tires mounted and balanced shipped to my door in 3 days from a place in ohio for 1580. It was a few months back but it was still cheaper then going to my local places in michigan which they wanted 2000 for the same stuff. They wouldnt price match so I said screw them I will wait the 3 days
