They are the weakest of them all. They wear out in about 60.000 - 100.000 km. Used them from 1999 to 2008, used two sets in that period, and most people here consider that alot. Used Precission gears.
Got 5.29's now even tho the tires are bigger than before. History states that the 5.29's are bunch stronger.
Cheers.
