Hi Johnny
I have 30,000 miles on my tires.They are down to a consistent 6/32.I believe they start at 10.I rotate every 5,000 at my oil change at the dealership. I've had one alignment as I bumped a curb and was going on a 400 mile trip and didn't want problems.I run at 40# .I did digital temperature Guage on discs,hubs and tires.Im kind of fussy.My normal driving is small town,lots of starts,stops and turns.I live in Wi.Im thinking ,after a trip to New Jersey this fall,and Winter approaching,I will buy new,they will not be down to the bars but that's O.K.Ive had such good luck,I'm just going to get the same ones.If winter wasn't coming I'd be curious what they'd run.I also believe whatever tire a guy gets,you have to take care of them!I avoid pot holes,curbs,r.r.tracks,road debris, keep the air up,balanced and alignment.
I was a semi driver,now retired,but things I learned, I still do,L.O.L I'M to old mess with tires.So Goodyear and motor on!!,Good luck!
