Having just had a new Dunlop Qualifier fitted i'm finding it VERY slippy turning into junctions at the most cautious of speeds. I nearly had an off this morning doing about 15 mph with the mildest of leans, it was wet though.


Is this expected with a new tyre or is it to with the fact they fitted the cheapest tyre they had despite me asking for the best, whatever it cost.

Isn't a Dunlop Qualifier a very track oriented tyre which will likely not be very good on cold, damp roads? Could also have been the most expensive...just not the most suitable...

I second the comment about that sort of tyre perhaps not being the best tyre for the road, especially this time of year.

that being said, give it a hundred miles to scrub in. usually though, when I've had new tyres fitted (more sports-touring...avon storms, well suited to the roads and work well over a wide range of both tarmac and tyre temperatures) I've not had any negative issues


Also, is it actually sliding, or is it more the tyre, being new and having a lovery curvy profile, is just allowing the bike to turn into the junctions quicker than you previously were used to with worn, squared-off tyres?

Don't they do a sportmax qualifier Which is a road tyre.

I should have said it was the front that was replaced along with the head bearings and fork seals, if that makes any difference.

I'm not sure if it is sliding or not. Its a sensation i havent felt before the change, its like it goes really smooth like being on ice and a wobble.


It cant be a track tyre as the invoice says £70 which must be entry level at that price. Also the Dunlop website only mentions the Sportmax Dunlop so it must be one of those.

I'm not disagreeing with yourself, and I'm not trying to cause an argument but I ran a new set of tyres on the track at the weekend and I gave them about 1 lap before I forgot about them.

If its a Dunlip Qualifier im guessing the profile will be alot steeper than the road biased tyre you've came from. That may give u the feeling that the bike is sliding, especially if you've came from a road biased tyre.

A new front tyre will alway feel like it wants to turn in faster than before couple that with new head bearings and it will feel completely different! It will feel like the front just wants to go! Give it a few hundred careful miles slowly working it up.

It only takes a few miles to take the sheen off new tyres. Just be nice and smooth with the throttle and it should be fine. That is in summe though I've never had new tyres in crappy conditions and I would be extra carefully but I wouldn't expect it to be slipping after even 10/15 miles.

No worries - it's advice I;ve been given, might be something to do with some heat cycles and also because on the road you dont use all the tyre sort of immediatly like on track

yes

I believe it's the heat cycles that cure the rubber so it works properly rather than miles. I suspect the 100miles comes from most bikes seeming to do 10-15miles to a cafe & park up, 100miles like that is several heat cycles.

Well this is an interesting thread. The main comment is that tyres tend not to work unless they're up to temperature. A Dunlop Qualifier is super sticky when hot and like concrete when cold. I wonder which its most likely to be at the moment?

As for the comment over it costing £70 WTF is that supposed to mean?

So... the rubber's not cured as soon as it comes out of the factory mould?

You are able "heat cycle" the tyre on the road, in March...

Cure isn't the right word, but I can't think what else to call it.

As to heat cycles on the road, yes my tyres are warm to the touch after my 21 mile ride to work even when it's frosty.

It is a Dunlop SportMax Qualifier. Which is a road tyre:


http://www.dunlopmotorcycle.com/tire-catalog/sport...

So far it has done 70 miles and has behaved no problem in the dry. Just in the wet it feels way unstable.


I'll see what it feels like in 100 miles or so.

Not trying to be funny, but have you seen the roads out there.

in the dry its fine, but up here they are almost white with all the salt and grim on them.

I suspect its just this time of the year im afraid. Any tyre is going to loose grip easy in 3 degrees on a greasy wet road.

What he said.

If I touch the accelerator slightly too hard in the car, the rear tyres light up like Christmas in the damp at the moment.

It's a combination of loads of crap and salt on the roads, no rain to wash it away for a few weeks and stone cold roads so threa not getting any real heat. And Qualifiers are almost slicks too.

I find myself agreeing with MTB a lot these days. He even rang me up and gave me mechanical advice the other day and I took his advice.

Is this one of the signs of the apocalypse?

perhaps, but best wear body armour and make sure you've got a bus fare on you for when you're dumped on your 'arris or the bike breaks down
