Three only, thanks to a deep pothole. Driven for 10 months. No sidewall curbage or other damage. These " Y" speed-rated tires were too firm for my car's suspension , so I fitted the "H" rated version, rather than replace the damaged one.
Priced at $60 each, they're a fraction of new which is $192 plus taxes and and levy, or about $220. Buy a new one to complete the set, and you're still way ahead.
These offer true sport handling but are quiet and wear well; check the reviews for these in the W and Y speed rated-rated vesions.
Tread depth is 7/32" (new ones have 10.5/32"). That leaves 5/32" before the wear bars are exposed. The D.O.T manufacture date is the 14th week of 2013. Made in Canada.
Price has been reduced for quick sale, but it is firm. Lo-ball offers will be politely ignored.
