I have a set of 225/45 R18's on my Kia Optima, This is the first time in the history of my million miles driven that I have EVER had to replace tires at 23,000 miles due to treadwear. I always driven a sports or performance car and have never had to replace them short of 40,000 miles. Will be looking for an alternative tire going forward. Also, snow performance SUCKED! slight hills and tires would just spin.
I leased a new 2015 KIA Optima EX (great deal, reliable and fun car) and these Nexen CP672 were the OEM tires mounted the vehicle. Miami, FL Driver. These tires would slip while accelerating from a complete stop. Especially bad while on wet roads - no confidence with wet roads.
The warranty listed on these tires is 70,000 miles - what a joke! I had to purchase new tires around 33,000 miles. Tires wore out so bad that I could see the steel belts on certain parts of the tires thread.
This tire is solely designed for the car manufacturer in mind as they simply slap on the cheapest tires for new vehicles due to discounted pricing (bulk purchases).
An absolute rip-off for consumer purchase - stay far away from these. Seriously, stop reading reviews after this and look elsewhere.
