Q50 Run Flat Tires

In 2014, the G37 Sedan became Infiniti Q50. G37 Coupe and Convertible became Infiniti Q60 under Infiniti's new naming structure - Here's the place to discuss the Q50 and Q60!

Q50 Run Flat Tires

Postby Gillis2143 » Wed Jul 18, 2018 6:15 am

Does anyone have this issue? My 2014 Q50 has Potenza run flat tires and just hit 15,000 miles. The tires are down to 4 on the tread life scale. It is a lease and if they get much worse I'll have to buy new tires before I turn it in which will get me off Infiniti forever. The car will have only 20K when turned in. What's up with Potenza run flats? The car is not driven hard at all.

Since some cars no longer come with a spare, or a spare is an extra charge, car makers install runflats.
Run flat tires are known for five major issues:
Less handling, higher price, more noise, higher cost, and premature wear. They usually wear out 6-10,000 miles sooner than a good quality non-runflat.
I reckon that you can replace the tires with non runflats and avoid the higher cost while still meeting your lease obligation. Best to double check that - just call the dealer, tell them you need to buy tires and ask if they have to be same brand and model. You don't have to give your name, LOL.
If so, I recommend Hankook S1noble2 tires. They are very affordable, drive like Michelins, and are silent on the road. They also wear out sooner than average, but will look great when you turn the car in.

Thank you! I'll be more aware in the future and never get run flats on a lease. 20K (estimated) wear makes me feel I got ripped off and future Infiniti leases will be the casualty. I understand some tires wearing out faster than others but 15-20K is unacceptable.

Yeah that sucks bud. It shouldn't be happening around 15 to 20K. Have you checked the rest of the tires? Do they have the same wear and tear. Dealerships do some funny stuff sometimes. Maybe they switched a tire or two and used your car in the process.

I'm curious as to just how bad run flat tires are, given the wide range of opinions/experience expressed on the Internet. I just purchased a 2018 Q50, with the Potenzas. Intuitively it would seem that maintaining proper air pressure is perhaps more important than with non-runflat tires, in terms of not dropping down 5-10 psi. I'm assuming the sidewalls may be more susceptible to damage than regular tires, for 20%+ range under-inflation.

I did some googling, couldn't find a specific statement as to run flat vs. regular under inflation susceptibility. Anybody have knowledge to share?

My '14 Q50s and my '17 Q60RS both came with the Dunlop run flats and I highly dislike them. Sure, they do relatively OK on wet and dry roads but from a reliability perspective and handling they suck. I blew one on my Q50 within the first few months of ownership and 2 of the others had side bubbles. They were replaced quickly with ContiExtreme DWS06 and I've never looked back.

My '17 Q60RS had the same tires and while I didn't have a blowout nor side bubbles they handled quite poorly. It was easy to get the car to slide sideways, you could feel how hard the sidewalls were, and they seemed to tramline the roadway horribly. Just replaced them with some Pilot Sport PS4S's and it's remarkable how well the vehicle handles now.

Hopefully the Potenza's are not as bad.

Why not the Conti DWS on the Q60???
We traded the 13 G37X yesterday for the Q60 3.0t awd and I am looking to replace the Dunlop run flats asap.
Top three on tirerack for uhp tires are Michelin sport 3, Bridgestone RE980, Conti dws
Was leaning toward the DWS or Potenza's.
Advice????
I immediately put Michelin Defenders on the 4Runner after purchase. Had Duelers on it and handled like crap.
Thanks!!!!

Performance tires were wanted on the Q60. The DWS 06 does not hold a candle to the PS4S when it comes to traction and feel, IMO.

I always regretted putting the DWS on the 04 RWD coupe instead of the S-Drives that were on it.....was thinking I MIGHT drive it in the little snow we got, but never did. I thought the DWS on the 13 G37X was a good compromise and it did well in the snow and OK when I pushed it a bit on the back roads. The Q60 is my wife's so I wanted an A/S so that's why the DWS. I'm driving the 4Runner now and the crappy Duellers only saw a few miles before replacing with Michelin Defenders.
Thanks on the congrats! :bigthumb:

Replaced my run flats with the Mich Pilot Sport 4S, the car is much better, better braking, acceleration, handling. They also provide a smoother ride. A huge improvement in every aspect. Bought a portable air compressor from Amazon for 50 bucks and a bottle of fix a flat just in case I ever pick up a puncture

I moved the Q60 wheels to the Q50 in order to refinish the G37 wheels I'm running on it. Man, what a difference! Crappy runflats vs. the DWS tires are huge. I need to get busy and refinish those wheels so I can get handling back in line.

Sheesh

I have a spare with the Q50 but not my Q60. Probably get one for it at some point as well.
