Raider put a brand new knobby tyre on his DR to head to the recent Desert Raid. Whilst travelling through the Polly Farmer Tunnel he thought the tyres sounded louder than normal. An inspection of the rear tyre when he got home showed that most of the central blocks had sheared off. The tyre was not run at low pressure and had only done 2,500kms.


Canvassing for advice on how it may have happened.

Bozo,

The Dunlop D606 covered 2,500 km, including approximately 1,000 km on the dirt. Standard road pressures used throughout - too lazy to drop pressures for the dirt sections...

Also, the Wiluna fuel resulted in the DR650 running very rough and consuming approximately 20% more fuel that 95 RON. Suspect it was Opel with something else included? Any other Desert Raid rider suffer similar issues?

Not sure if 12 hours to run Well 5 to Nedlands had anything to do with anything.

Cheers,

Raider

Stirling Highway in Nedlands a bit chopped up Raider!!

It seems the tyre has a speed rating of 170 Kph so that is not an issue.

I’d hand the tyre over to Dunlop and get them to come up with a possible cause (without laying blame) because this needs an explanation. I’ve done about 60,000 km on my DR and run the same tyre and never experienced anything like this.

His Royal Griceness and I continued our journey after Desert Raid while riding identical bikes (DR650). He was running standard gearing (15/42) while I was running lower gearing (15/45). I used a third more fuel than him and I put that down to lower gearing and a well worn engine (his bike is new). Both bikes performed well (no engine issues) and HRG was happy with his consumption.

The only time I have had issues is with an old Tyre left in the sun and then being refitted to wear it out.
It started to tear off knobs on the sun affected side of the Tyre.
It did not get as bad tearing of knobs as Raider on his D606.

A few years back I came across a guy on the central road who fitted a a new 606 in Perth, by the time it got to Geraldton it had done the same thing as Raiders, it got replaced in Geraldton and I think the same thing was happening to him when I saw him.
So I guess Dunlop have had problems on and off for a while, I can’t recall the make of bike he was on.
