Follow-Up Review: 13,927 miles on tires
April 16, 2014
I did my last review in Burke, VA. I am now in Huntsville, AL. My earlier comments are still applicable. Here are some updates. If the tires sit for more than a couple days, they develop flat spots. It takes 30 to 45 minutes of driving for them to somewhat even out. As the tire has more mileage on it, the cornering has become abysmal. I have takien turns a little faster than normal and the car has walked out from under me when not expected. This was done in warmer weather where the tire is supposed to do its job. It is a crappy tire. It is a shame Jaguar would even put a tire like this on one of its performance sedans. Also, the tread is down to 6/32 of an inch, indicating I will be lucky to put 28000 miles on them. I am seriously now looking at the Michelin Pilot Super Sport A/S3, so I will have cooler weather handling capabilities also. Whatever you do, DO NOT buy this tire if you have a performance sedan. There are much better choices out there than these pieces of junk.

The rears are 285/35ZR20. Yeah, I know these are summer tires, but I would expect SOME sort of capability in temps between 32 and 50 degress. These tires cannot be relied on for any kind of performance applications at these temperatures. All my comments refer to these temperatures and not summer temps. Even with moderately aggressive cornering, the tires act like they are going to pop off the rim. With pseudo heavy throttle, they have minimal traction. They break loose with just the slightest amount of power application. I would go with the Continental Extreme DWS if they had better sidewall rigidity. If you are going to stay with a summer tire on your supercharged Jag XF AND would like to do SOME driving in cooler temperatures, the Dunlop is not the answer. Consider Bridgestone or Michelin.
