Question Tire on backwards, Bad?

Here are the details.

As many of you know the tread pattern on front D208's are reversed. Well, I had a new one mounted and I just realized he put it on backwards. I guess I'm almost as much of an idiot because I just noticed it and I probably have 1000 miles on it. Here is the question. Should I simply have it re-mounted correctly, or is that dangerous. I'm inclined to pitch it and get a new tire. I'm concerned that I could break the belts if I run the tire in the opposite direction. But, I'd hate to trash a tire with so much life left.

Opinions.

BTW. I stopped taking my bike to that particular shop.

Do you still have your receipt? The person who mounted the tire should have their name or initials on the receipt somewhere. I would go back and talk to them. Good chance your not the only one. How much business do you do with them? A good business man would not want to lose a good customer for the "cost" of one tire (which is much less than you paid for it). Especially if it is a repeat problem from that mechanic. They could give you a new tire and probably break even for the price you paid for the first one!! Go in and be understanding but firm, and try to speak with whoever is in charge, not just a supervisor, they will be more in tune with your business relationship. Good Luck

same exact thing happened to me, shop fixed the tire, wouldnt buy me a new one or change my front pads( they get worn down really fast be seeding up to new roters) im not bringing my bike there eithert. ps, dunlop(i had a 207) told me that a reversed tire on the front would force water to the center of the tire if you were to encounter rain or a puddle, bring that up to the shop, how theat thier mistake could have been fatal to you. glad you caught it when you did, without a crash, i got a sick feeling in my stomach after reading dunlops email to me

good luck

It used to be that mounting tires backwards was a pretty major bad - The belts went on using lap joints where they attached to each other. It's called a "Lap" joint because one end overLAPs the other. Anyways, those tires are/were directional because if you ran them backwards, flex could potentially cause the overlapping piece of the join to separate, resulting in catastrophic failure.... VERY bad...

Now tires use a lighter straight seam (Butt joint - one end butts up against the other...), so they can't/won't fail that way. But tread and belt design is still meant to work best in a certain direction. It won't fail on you, but I'd still bitch at the dealer and make them fix it.

Exactly right. Get it fixed but don't panic.

I read something on this in Sport Rider a few months back. I don't remember the upshot totally, but I think it said something about Dunlop testing the (pre-production) tires mounted both ways and marking them (the production ones) for the direction that performed better.

Not really helpful, but food for thought.

Thanks for all of your replies. I've been hearing alot of bad things about this shop recently. Apparently the guy has a hard time keeping things from going up his nose.

I'll get it taken care of
