1 yr and 4 months on stock '09 37S sedan, 18k miles, should go to 20-22k with spirited suburban driving.

 

Hey guys...thanks for all the input...it's a shame they put such crap tires on the car stock. You would think they would toss on some good tires to give the best experience off the car lot.

Anyways, just how bad is it to drive on tires up/past the wear bar? I do realize it's not safe in wet terrain, but it hasn't rained in weeks in Florida and I'm wondering how far I can wear them down. They are no where near BALD, but pretty much down to the wear bars in the middle portion of the passenger side rear tire, but more meaty on the inside/outside of the tire.

 

Overinflation.

 

Which, coupled with the balding tread, greatly magnifies your risk of hydroplaning if you do get caught in a shower.
