I have put 11,500 miles on my Vizzoni Mudz Mt 275/55 R20 tires and all 4 are in great shape. 99% of my driving is too and from work which is mainly highway. I rotated the tires at 7500 miles and due to a heavier load in the bed most days. I would recommend these to anyone in construction as they have got me out of a few sticky sites when it was raining.

I have only put 10000 miles on these and the part of the tread has separated from the outer ring of lugs. It has caused a very rough ride and will be getting ahold of customer service to resolve the issue. Up until now it has been a pretty decent tire at a vey reasonable price.

Hardly any road noise, good on hard pavement and off road. Just installed so I don't know about winter.
