Tire Life

Postby veg_eta_ble » Wed Jul 18, 2012 12:11 pm



Sooooo...after spending almost two weeks in a hospital with 4 broken ribs, a cracked hip and a collapsed lung I really have to ask, what is the life expectancy of tires on the wing? My rear one blew out as I was spooling up to 65 mph. I managed to get her down to 35 before I dumped her. I check tread and pressure every week and have seen nothing to concern me in anyway. I have 10293 miles on these tires, just mounted in 2011. Any help would be appreciated because I do not want to do this again. :shock:

What tire were you using??

Dunlop and I don't remember which model and there is nothing left of the carcass to tell either.

Wow, that's terrible, but good that you can tell us about it.

Obviously, you should get more than 10,000 miles out of a tire. Unfortunately, you may never know what caused the blowout. Was it a defect in manufacturing that caused plies to separate? Debris in the road? Sidewall failure? Puncture, deflation and bead separation? Could be any or none of those.

After riding with the TPMS I put on my GL1500 for a few weeks now, I'm just blown away that I went this long without one. It really gives you a good idea of what's going on underneath you. Temperature/pressure suddenly spiking for no good reason? Pressure suddenly DECREASING? Time to pull over and figure out what's going on before I find out the hard way.

I whole heartedly agree with "glad you could tell us" statement. Even though my wing has some damage, a good amount of pain and bucketloads of pride lost, I do realize that this could very well have ended 10,000 times worse. I had no tattle tail signs of vibration or noise before incident. I was at 65 mph for 20 min prior, slowed down to 40 mph to cruise through a little two horse town, then as soon as i hit 65 mph, :o and heard the blow out I knew the rest of my ride was going to suck. I really don't want to go through this again, but if 10,000 is all I can safely get then I guess I will be buying more tires.

Glad you can tell us about it I just installed new Metzler ME880's, so I'd also like to get some thoughts on tire life expectations as well!

Really sorry to hear about your spill, I have driven 100K's of miles on motorcycles and had a few tyres fail, but never ended up with an accident, that is some serious bad luck.. As mentioned, glad to hear you are still around to tell the tale and even more happy to hear that you will get back on and keep riding.. Most bikes I have eat the rear tyres in around 5 to 6 thousand miles (I only owner large capacity sport bikes in the past R1, CBR900, etc) my wing still only gets about 7000 miles from the rear tyre (AVON tyres) but I do have a heavy right hand.. The usual cause of tyre failure, is puncture, overloading, or manufacturing defect.. From your description I cannot tell which was the cause, under inflation or overloading all lead to the same thing, excessive heat which causes the tyre to fail, a puncture can also cause the tyre to fail or make the bike to unstable to ride.. Most people seem to run the tyres on a wing at a higher pressure than Honda recommend, Honda recommend around 36PSI and most people seem to run low 40PSI. As long as the tyre is correctly inflated and has no cracking in the sidewalls and tread on the tyre, then you should be good.

Hope you get back on the horse very soon..

What a bummer. So glad to hear that you're on the mend. What tire pressure do you normally run in your Dunlops? I run about 40 psi in mine. Thanks, and a speedy recovery to you.

I was running 40 psi on them. And thanks for all the well wishes, guys. My wife says she is all for me working on my wing just as soon as I am able to mow the lawn. :twisted: :twisted: she is worse than my physical therapists! lol. My kid is upset with my thought that the only reason I would no longer ride is if this accident had anything to do with a lack of ability or judgement on my part. Until that day comes I will continue to ride :D .

Glad you're OK.

I was curious about this post because I just bought a GL1100A that's been garaged for 3 years. The tires were relatively new, but I noticed and major rub on the left sidewall where the tire rubs the upper brake caliper bracket. It's a Dunlop D404 140/90-16. Apparently these Dunlops are about 1/2" wider than other tires. Wonder if that was a contributing factor to your tire's failure...

I had no rubbing on my tires and I would really be concerned with a tire rubbing anywhere, esp if it is on just one side. Could the PO serviced brakes and somehow installed wrong? Or if it is on the rear tire, was the spacer bushing left out of the axle? And I would look closely at the sidewalls for any oxidation cracks. Personally after my experience, if there is any doubt, change them out. Happy riding to you. :D
