A lot has been said, with good reason, about excessive rear inside tire wear. Boiling it down all together would help to to understand. I just lost probably 8K of use on the original Goodyears, when inside cord appeared with only 7K on the tires, (and only half of that on the rear). In hindsight, wear may have been accelerated by setting the "low" suspension to 60mph when 5.9 arrived, so I have reset to 75mph. I am wondering if it is known: How exactly does camber change with the suspension heights. ? And if it saves tires, why can't we adjust the suspension to stay in "high" around town under say 45mph if desired? Does it affect geometry and handling significantly? I have an appointment at the SC next week to take "some" the negative camber out. I've read the great advice by @lolachampcar and others about optimized alignment and camber, will request those optimized settings and hope this will help. Even at the lower cost of the Goodyears versus more premium tires, the cost of rubber approaches DOUBLE the cost of kwh/mi driven, if you lose half life on the tires...., Personally, I will gladly give up some aerodynamics, and take a bit more rolling resistance in the tires, to get to 15-20K per set.
