At just over 4,200 miles, the feathering has started. Uneven inner tread blocks on both front tires. Now, I am considering to let them go and get new tires, or go in for the tire swap. I am leaning toward the former since they will need replacing eventually and I would rather the dealer screws around with my rims only once.

Nissan has a problem with this and I think every Z will wear tires out this way. I don't think toe settings has anything to do with a fix either, it's either caster or camber that is at fault. Nissan is adjusting the only thing they can change and that is what they blame it on. I am going to make them replace a hundred tires if needed!!!!!!!!!!!!!!!
