Okay, I have looked for this subject in the search and have not found anything which helps. After installing a Hannigan kit on my 2009 LT, I have found that the front tire, a Metzler 880, is showing abnormal wear. After about 6,000 miles, it is wearing right down the center of the tire. The treads are almost gone. Of course, the sidewalls will not wear because there is no leaning. I have heard that some have retrofitted a flat profile car tire on the front. Seems to me that this could be a bit tricky. I would appreciate any input on this subject. Thank you all.
