Dunlop SP Sport 5000 DSST CTT 

Awful tires. Some of the worst I've ever driven on. Low traction in the wet, mediocre grip in the dry, rough ride, and noisy. The fact that these cost almost $500 a piece is a joke! Tires at half the price of this are so much better! I also have had trouble with sidewall blowouts as others have mentioned in the comments. Buy ANY other tire.

This is the worst tire you can get. Especially if you have to deal with rain and winter a lot. Traction isn�t good. You tent to oversteer going over a puddle. Always give me the anxious feeling driving when it rains. (Sometimes in general)

This is the worst tire I have ever driven on. Infiniti should be ashamed for screwing over us car buyers. This tire has been used about 1 year, but only about 8,000 miles because I used winter tires for 5 months. They are already down to 5/32. Traction in rain is terrible, do not even attempt to drive in the snow or ice or you will end up in the body shop. The replacement cost of these crap tires is insane, almost $350/ea, at minimum! Do NOT buy these tires!

Unacceptable OEM tire that Infiniti uses. Loud tire that pulls car side to side on uneven roads. Don’t even think about using on snow or ice.

Garbage OEM tires. Amazed Nissan puts these on the Q50/Q60 RS 400. Mediocre dry performance, poor wet/snow performance, and the worst tread wear of any tire I've owned.

These tires are terrible. They ride hard, don't inspire confidence, feel dangerous in the wet and snow. Hidroplano like crazy. They make a sports car feel and handle awful. Had a tire go over at pothole and the tire walls cracked/ exploded. Never had a tired do that. I could have gotten a free replacement from Infiniti but instead, I replaced all four tires with Michelin Pilot apt 3+. I wouldn't put these tires in my car if they paid me to. Infiniti should be ashamed to use these terrible, dangerous tires in it's cars.

So disappointed in my infiniti. My past 2 leaves with infiniti, well I did not have to change any tires from.beginning to end. With these tires, I replaced one this may due to the sidewall blowing out, and now its October and the other 3 are worn down and eont pass inspection. No way I'm paying $2000 for these tires. Ride was always loud and felt like the car was slipping on dry roads. Stay away.

STAY AWAY FROM THESE TIRES!!!

It should be illegal on how poor these tires perform in ANY category, wet, dry, ice, ANYTHING! My brother, who has extreme summer performance Falken tires does a wayyy better job in rain and snow, and they are cheaper. One of my front tires recently started having a random inner tire wear, and even after an alignment, it was still wearing that one tire. Also road noise sounds like you are constantly driving on rough roads and it feels like it too, it’s ridiculous! If someone is telling you to get these tires, they probably don’t like you. These tires belong in the trash!

It really is amazing how awful these tires truly are... if I was trying to make them somehow worse I'm not sure what I would do. Besides the harshness, noise, incredible wear rate (down to 7/32 at 10k miles), horrendous traction, and PRICE, the worst part of the tires is their ability to redirect your car along road imperfections. It feels as if there's some auto pilot trying to take over the car if the lane has any wear or grooves in it. Any kind of snow/slush/ice is just immediately dangerous. These manage to negate any AWD capabilities of the car. I cannot fathom how these tires are available for purchase, and pity anyone else who ends up stuck with them as their vehicle's original tires. Infiniti needs to wake up and realize the damage these tires do to their brand. The only saving grace of these is they'll wear out quickly so you can come back to this site and get some real tires. I cannot wait to get some Continental DWS 06's as replacements.

Tires came OEM with the Infiniti Q50S.
Cannot convey how hard these tires are. Comfort almost non exhistant giving harshest ride I have ever experienced.
My third Infiniti but first with run flats and cannot wait until the Dunlop's have to be replaced with non run flat tires.
Wonderful vehicle, but these tires and run flat capability really diminish joy of ownership.
To top it all off, the Infiniti came with run flats, but with a full tire jack and spare!

Guys, I am sorry but I will only be able to write the truth. This is a piece of ---- tire that should never even be installed on factory fit from the company. Way too noisy, minimal comfort, it just destroys the experience of driving. Well, even for sportiveness, its not as responsive as one would think while accelerating. Does not provides any grip in little snow either. A punture in the tire is difficult to patch, and no local companies were willing to do it, so I ended up getting rid of them at 31K miles and getting the top rated Pirelli Cinturato P7 all-season plus. I will never buy the Dunlop Sport 5000 DSST CTT Run flat ever again. Well I am lazy too, but this time I had to write a review for this scum of the tires.

These tires are terrible, treadwear was ridiculous, below 4/32 prior to 15k Mike’s completely bald by about 26k miles.

When I purchased my car, the salesman strongly suggested that I purchase the wheel/tire coverage... I'm glad I did. I've driven the car 50,000 miles, and have had 5 tire replacements so far due to bubbles forming in the sidewalls. This usually comes after hitting a pothole, and gives the "wobble" noise. I've had uneven tread wear, the inner sides of the front tires thinning down to the wear bars, while the outer edges wore as expected. Have had the alignment done by dealer multiple times, still wearing uneven. Unlike most people, I prefer the stiff, hard ride - that's why I bought a sporty car. Sidewall bubbles, and tread life are the two reasons these are the worst tires I've ever owned.

Replaced 6 tires in 12500 miles due to boubles on sidewall all due to minor potholes. Tire wear is terrible and even with new tires balanced 2x at dealership still did not feel smooth on highway.
Moved to Continetals and 0 issues after 20k miles and counting.
