Help! Start of 7000km North Island trip, stuck in Levin with a dud GN250 front tyre

[Ocean1]

18/300. I've only been riding for a year, so I'm a newbie. I've done 30,000km, and about 5,000 of that has been off road. So - not a lot, but I'm comfortable enough off road for sure.
Yep, checked the guard, and even with me pressing down on it and spinning the tyre it doesn't touch.

Think you've squeeked past newbie. Just.

And a straight road tyre should be quite manageable on dirt. Even gravel, keeping your weight back a little.

Good luck, eh? Let's know how you get on.

I've previously taken road tyres on dirt/gravel, but we're planning on doing a few bigger gravel roads (lake waikaremoana, port jackson, 90 mile beach etc), and most of it with fully packed up bikes, so wanted something a little less slippy.

Talk to Stu, if that Shinko's a dud they'll see you right, hopefully with something a little bit knobbly. But don't forget you'll lose a bit of grip on the road, especially in the wet.

Luck.

Thanks - I've got my fingers crossed for a dry couple of weeks, but I'll definitely keep that in mind.

Cheap Chinese rubber.

They are actually from South Korean, don't know if thats much better than made in china ?



GN have a 'Farm" version with a Nobbly type tyres http://www.autobase.co.nz/motorbikes...er/1136226.htm
assuming they are road legal they could be a good option

I've had a look at those, they're too knobbly and would be noisy as hell on the road, I suspect.

[spanner spinner]

these work well on gn's and you can get them in the right size and they are a good shingle road option will work off road if it's dry http://moto.michelin.co.uk/tyres/michelin-m45

only problem will be if the importer has any in stock at present. I do think that this is just a problem with your tyre as I have sold lots of shinkos and not had may problems.

have you thought maybe the tyre grows a little in diameter at speed and does contact something?
check for signs of wear on the guard or gaurd mounting points?
take the wheel out and check under the guard between the fork legs

Thanks - I'm a little less sure about that one (having done no research) cuz I ride in the wet quite often and I think it looks like it could get gunked up quickly - what do you thinK?

Yep, thanks - I've considered that and there's no wear on the guard or any indication anywhere that it's rubbing. On the tyre you can see how each of the parts have started peeling and I just can't see how it could be from contact - it's on the wrong end of the tread.

Yep your right don't like mud to much turn into a slick real quick, wet weather performance on seal is ok.

What a bugger about the tyre, even a cheap tyre shouldn't be doing this.

On another note, how did you do that Trip Plan?

Pretty sure it is the my maps feature of google maps (click on the 3 lines/options thing while on google maps and you should be able to find it) I have used it for noting down a couple rides I have done/want to do. It kinda works some of the time but doesn't always show you the info you want (eg total distance for a plotted route)

Question?
You were / are touring. How much weight were you carrying over that back axle? Probably not an issue if it was just one up but perhaps a combination of knobbly tyre and higher speed than the tyre was designed for with extra weight over the back may have had an effect? Just a thought.

I've got one of those on one of my bikes, branded Golden Boy, but it's made in the Shinko factory. Great tyre, and really good in gravel....and mine is still in good nick, but hasn't done many kms. I've been using Shinko for the last couple of years - 3 rears and one front, I'm enjoying them better than the Bridgestones I've had on the same bike before.

That looks like physical damage to me too, something has hooked that tread out. If not, check the date stamp on the tyre, it could be old stock.

Its the front tyre that has the problem.
