Whats going on with my rear Dunlop?

[CoronaBoner]

Just got back from a quick ride and noticed I was having grip issues on my left turns, felt very weird as I was driving out of corners.

I have had this rear tyre on for only a week now and its showing signs of abnormal wear already? the pattern is consistent throughout the whole left hand side of the tyre and is very very sticky to touch...

The PSI is bang on 36 which is recommended.

The right hand side is fine, but I do tend to push left handers harder, but I can't see how that would do this to my tyre.

Its the latest Dunlop, 208rr model I think, any ideas to why its getting like this? as it cost me £120

is the chain rubbing on the tyre?

[CoronaBoner]

Very good idea, I'll go check.

Agreed, looks like chain rub, if the rear tyre is the right size your rear wheel must be way off straight

Sounds like the most likely reason. Either that or the tyre is rubbing on the swingarm/hugger.

Also make sure you're axle is tight. If not there is a possibility that the tyre alignment looks fine when stood still but the wheel is moving slightly under load.

Yea it is the freaking chain If it does end out to be due to an ill fitted rear then can I get my money back? or get a new one as it looks shagged for week old road going tyre.

Cheers guys.

Something seriously wrong then - Very bad alignment? spacers not in correct place?
Wrong size tyre?

[bish777]

thats very bad!

The tyre would have to be very oversize to do that so I suspect the chain and rear wheel alignment is way out.

As has been mentioned before, are the spacers fitted correctly?

Id check it and see-if you took the whole bike and had them remove the wheel, you need to get them to sort it out. They should do this gratis and a new tyre too!

Hi

Also worth checking that the spacer between the sprocket carrier and the wheel is in place. If that is missing then there is a good chance the bearing in the sprocket carrier will collapse, and the swinging arm will be wrecked when the studs holding the spocket on touch it.

All the best

Can't do sod all till Tuesday as all the places round here close Sunday and Monday.

Its the right sized tyre, 190/50, SDC performance said a 180 would fit in just fine but I really wanted to stick with stock as I am comfortable with the bike as it is.

Annoyed as it could have been dangerous had I not looked.

Also managed to nail a bird that got stuck in between my yokes Been trying to scrape all the crap of my forks.

Some day!

One thing is I don't own a Torque wrench and would not trust myself messing with wheels.

I'm happy to do the brakes oils and the other basic things, but I spent £120 quid to get this done so why should I bother to go to the trouble of taking the wheel off and checking myself all because a "trained" mechanic could not do a proper job!

It's going back to the shop Tuesday where they can fix it.

I only chose this garage as it was a quick solution to getting it sorted as I had a big nail stuck in the one before it, and they happened to have a Dunny in stock.

SDC performance would have been place of choice but they would have had to order in the tyre.

Ive got a torque wrench you can use (no idea what setting would be as havent used it yet) but i dont have a socket set big enough, i need to get a 30 soon for my rear wheel.

Best bet is to leave it on as some garages will try and say it has happened since you took the wheel of, or just dont tell them you've had it of. Let them pay for it and sort it out , their mistake after all.

I think you can use common sense for an axle bolt TBH.

[Dom_]

You'd prefer to tighten the sump plug and filter without a torque wrench but you won't do the rear wheel?

I've never used a torque wrench on wheels, it's just common sense as to how tight it should be. Why not have a look yourself, will take you 30 mins, you'll gain some experience and you'll be able to spend more time on the bike if you fix it.

[CoronaBoner]

Yes basically....

Like I said, they screwed it up, they can fix it. Not going to cost me nothing.

May even get a 180 put on to see if theres a great change to how fast it turns in.

UPDATE:

Well now I really am confused..

Took it to the reliable garage where they got it up on the bench and gave it a good look over, first thing they said was that the tyre didn't look right, as if it were too flat and wide..

Everything had been put back together spot on, so this was causing some confusion as to why it was making contact with the chain with a standard sized tyre that should work fine, as it has done the 3-4 times before...
The actual tyre in question is a Dunlop D208rr Qualifier.

So they got onto the phone to Dunlop and specified the problem. Dunlop basically said that it could be an iffy one of the production line as they do get some that are not 100%. So basically get it swapped from where it was done.
They also told me that it would fail an MOT like it is at the moment! ( got that in 3-4 weeks time :O )

So going back to the place that done the actual tyre fit are saying that my chain is loose and thats whats making the contact andcausing the wear.
But the other garage say otherwise... and if it were the chain, then why did this not affect the previous tyre, and even if it were loose, is it not the duty of the garage to check this when putting on a new tyre?

So how do I go about getting this resolved as I have a week old tyre that cost loads and won't pass an MOT..

A good chain does not move that much side to side. It mainly goes up and down. The shop is talking crap to fob you off.

[SoulRider]

Let me come down with you, i wont take no for an answer.

End of the day you have confirmation from dunlop saying that it is a dodgy one of the line and it needs to be replaced.
