I compared both the Pirelli's and the Mudlites, I did notice that the Lites tread was noticeably different to the Pirelli's. The tread where it is cut out appears to be a little deeper to me and more pronounced on the Lites. I would think that this would give a better grip on rocks and such but it would also appear that they pick up small rocks more than the Pirelli's would. I don't know, for the price, I would compare them and see if there's enough of a difference to not buy them. They list for $58 on the website I saw them on and that was for the 26x10x12's. I think the Lites run closer to $69 in 26x9x12, thats $40 that you could spend on something else for your machine.
