Our first trip wheeling after putting a set of 30x9.50R15 GoodyearMT/Rs on our '98 Cherokee sure taught us a lesson. After completely losing two rear flares and having one front flare knocked half off from the tires hitting them, we were kind of peeved. While the Cherokee isn't known for generous wheelwell openings, the '97-and-up flares really got to us. They are basically clamped on and one good hit from below can knock them completely off the Jeep.
Sure, we could have just lifted the Jeep, but with all that plastic and sheetmetal above the tire that just doesn't need to be there, why not take out the angle grinder and make some noise? We wanted to stay low-budget, so we went to Quadratec and got four rear TJ flares (two driver-side [PN 52449.0160], and two passenger-side [PN 52449.0159]) for our project. For $120 plus shipping, we got an additional 21/4 inches of clearance over the front tires and 3 inches of clearance over the rear tires, without having to mess with shocks, brake lines, or driveline vibrations.
