Dunlop Q5S On Track Tire Test - Destroyed in 5 Session!?

In this video I try out the new Dunlop Q5S Sportmax tires on my 2013 Suzuki GSX-R 750 out at the ridge motorsports part for a 2-fast Trackday. How do these tires perform? How is the grip? Most importantly, how long do they last?

I had that same experience with Q5s on my S1000 at the track. I was a little concerned after the first session because I was running warmers too. My tires were absolutely torched after just 4, 15 min sessions to the point I didn't want to ride on them anymore. and for as expensive as they are I think I am just going to stick with supercorsas as I can usually get about 4 days out of them.

I went through 2 sets and had the exact same experience. Regardless of what pressure I used, the tearing and wear was terrible. I’ve seen countless posts on Facebook describing the same symptoms. Switched to the supercorsa v4, which are also cheaper and they have lasted way longer with similar levels of grip. Dunlop messed up getting rid of the Q3s…

Thank you for making this video, I'm glad i saw this

I just had the same experience. Was excited to try the q5's this last weekend. Rear is completely destroyed after a day. Same kind of tearing and spent all day messing with tire pressure. The front is doing great and I was thinking about running one more rear until the front is gone. Not gonna run these ever again after that. Probably go back to cup 2s.

I'm on my 2nd set of Q5S's on the street on a CBR 1000RR. I ride it hard from digs but don't really go above 120, and if so it's just for a blip. My tires held up really well for just about 10 months. Not getting that clumping on rubber. IDK we'll see how this 2nd set goes.

I can see his suspension is not set up right? Need to set compression and rebound causing tire to chatter tearing rubber

[angusmcleod]

Same shit here, rear garbage after 5 sessions I chased every possibility including slowing down and using less throttle out of corners.

Wrote Dunlop about it and they pretty much told me to run a harder compound next time

"The wear you are experiencing is a direct result of the abrasive nature of the track you were using the tire on and the Q5 being too soft to cope with that type of pavement. The Q5 is ideal for less abrasive tracks, but for tracks with more abrasive surfaces (or newly repaved tracks)"

[dmaggio]

Very interesting…..thank you…..
I am no pro … but in my opinion, it looks like the surface of the tire gets hot, but the carcass is not up to temperature… it looks just like cold tearing I’ve seen on Ray tires that weren’t on the warmers long enough….. I bet if you had warmers it could preheat the whole tire they would wear more evenly…..
you gave a very informed report I’m gonna let my buddy know about this …..

[SlingKing]

It's not super easy to tell from the video but it does look like hot tear. It also looks like it could be inconsistent, so along with your pressures, I'd check the suspension setup. You probably need a rebound adjustment at the very least.

[pnwgreg]

I think this is consistent with other Q5S experiences, just wears out too quick. I like S22's but I"m a tick (or few) slower than your pace. I'd be keen to try Rosso Corsa's as they seem to have consistent tire wear every bike I've seen them on. Or just stock up on Q3+'s lol

[rogerychen]

Thank you for you straightforward content. Was wondering if you ever compare road 6 to the Q5s. I am not going to track but like riding aggressive in back roads

[SquireSCA]

I had a Q5S on the rear of my ZX14R and 200 miles into my trip up at Deal's Gap, I was getting delaminating between the tire compounds... There were two lines going the complete circumference of the tire, where the different compounds were pulling apart and tearing... I ride the bike fairly hard and do track days on it, but I have never seen a tire split apart like that... Talked to Cycle Gear where I bought it, and they said that several people had come back with the same issue...

Being from Washington I never went to the track … I regret it … just finished my 3rd track day here in Florida and glad I finally did it !!! No regrets

[Memommxi]

I’m
Not an expert but to me the 37psi looked the best. Maybe bump up a half pound from there. Your buddies advice had you cooking your tire lol. I don’t blame you tho 36psi hot sounds really high. But the wear looked the best. Plus pressures will be affected by different temps throughout the day. I’ll try these soon since I’ve been a HUGE fan of Q3+.

[jorgevarona]

Getting your suspension tuned for your weight and riding style will help improve how your tires perform and last

[bbguardsp]

I strongly suggest sending this to dave moss and getting his opinion. Clearly pressure should have been a bit higher rather than lower like your friend suggested at that specific point in the video.
Did you have your rebound and compression set correctly? Change it between sessions?

[masimak]

If your springs are too soft for your body weight, rapid wear will happen, primarily and especially on the side grip.

[forestedelman]

Might be a good idea to check out dave moss tuning videos

[EAtz]

The Q5 seems to be softer compound, might be better for cooler track days and hot days it’ll shred tires, v4, power GP, metzeler racetec, Q3, 9RR, power 5, power cup they all good tires too I wonder if any of y’all tried em any info would help. Tried Q4 and good grip but I didn’t like the feedback during fast switchbacks due to circumference of the tires. Thanks for review I was thinking bout getting the Q5.

[DannySpins]

Wow that's wild. Love that it gives a ton of grip so that'll be great since I'm a novice but it sucks how fast it wears out. What pressures did you find best to keep it at?
