I currently have the 7 inch AT tires but I’m planning to get some 8 inch tires for a higher top speed. My first set of tires lasted 1000 miles. The 8 inch MBS tires look like they won’t last that long so I think I’ll finally try the 107s after that for more speed. Can anyone that has the 107s please tell me approx. how many miles they are getting per set?
