Unhappy Crack in Dunlop D222

Hey guys, I was in the track today, and noticed a BIG crack on my front tire. Anyone got similar problem with their Dunlop D222?

My CBR500R 2017 is less than 900 km.

I noticed a very thin line on the tire 2 weeks ago and didnt pay attention to it, now it is 2mm wide, 3mm deep and 5cm long

Please check the pictures and let me know if you think what could have happened.

Regards

That looks more like a cut (maybe a metal price on the street?) Than a crack.

Upgrade to Dunlop's q3, gpx 300 if you like the turns, or Michelin pr4 if you're more a touring guy.

well that sucks ... and no, i don't know about anyone here on the forum with a similar problem, so it may be a cut from a piece of foreign object on the road / track as @Manolosal mentioned with only 900 km on the tires, it's a real shame ...

now you have two oprions, buy just the front one or swap to something more track oriented, since you are riding track days ... there are several threads on this forum about tire choices, my personal favorite (for now) that i will be putting on the bike when i wear down these stock dunlops (they have about 6000 km now and still look like new dog gammit), are bridgestone battlax s21

I will check with the dealer if this is covered by guarantee... I was thinking on the Metzeler Z8 recommended in the manual if the guarantee does not apply in this case.

Z8 interect has been superseded by roadtec s01. for track riding dunlop Q3 is a better proposal.

Thanks blackburn. Here in Chile we still have Z8 (seems we are 6 month to 1 year behind the european market!)

I bought this motorcycle under an agreement to run it in a Honda cbr500R catergory and there are restrictions that requieres me to run the mortbike stock, so I assume I must stick to stock tires or the ones recomended in the manual, which is Z8. Probably the Q3 is better as you say. Not sure if the organization would aprove this "improved" tire.

well, z8 is a good all seasons sport touring tyre nonetheless.
some says it's the same tyre as pirelli angel gt with different thread pattern.

Funny this post like this went up. I've got 6,500 miles on my back tire and noticed a couple little cuts on it for some reason or other. Close to needing a new tire but I've never had a tire show cuts like this before.

I did about 18,000 km on stock D222s and had no issues like this. They never went on the track though. I also had the rear plugged at about 4000 km after picking up a screw. I also a couple of times had to pick out glass from the tyres.

Those tyres look very worn for 900km, regardless of the cut.

That's 11,000 miles...if I can get that on this back tire, I'll be real happy.
