I purchased a new car 12/15/2017 and one of my tires has developed a slow leak. I was wondering if this covered under any type of warranty or if you fixed tires for free?

Not sure, but I thought that would be predicted on warranty, like 60,000 etc, unless you purchased road hazard warranty.

I would call your salesperson. We have purchased 3 vehicles from them and they have always been fair. If not Monday morning I would be sitting at Discount tire as they too have always been fair.

you should be cover, takes ad soon as posible.
