Damaged Tire? Is it safe?
« on: May 04, 2016, 11:29:10 pm »
I bought and installed this tire last autumn and just noticed this week it has cracks all along the rim on both sides.
Is it safe to ride on? I'm not sure, but it does hold air.

 :-\ wow what brand of tire? If I saw that I would be asking the same questions. Those cracks looks deep, so I would not be comfortable with trusting that tire.

  I agree with 4Bikes. I would not trust that tire.  Your life is certainly worth a new tire.

I'm not going to reveal the tire brand. To me, it doesn't matter.
It's either safe to ride on or not.

Now, in the past, I had another tire I rode on and wore out before noticing a couple of cracks, without incident.
But this one with so few miles, gets my attention.

I'm no tire expert but I have to agree with the majority here. I would at least check with the mfg. to see if they will help with a replacement. Maybe a type of pro-rate if you will. Worth a shot.
Thank God you're alive every time you arrive!

Hmm...not even 3 years old.  Looks like hot/dry storage or manufacturing defect.

I would have to agree.
If I'm wondering about it, best not to ride on it.

Now the question is, where is the damn receipt?
I have another tire still wrapped in plastic from the online seller.

I'll have to look into it.

Tire was purchased from Bike Bandit. I have the paperwork that was received with the tires which has the customer PO number and all.
I'll call them tomorrow when they open and see what they have to say. The front tire is still wrapped in plastic and I was going to put it on this summer.
But now, I'm not so sure I want to do that till I know more.

That picture makes the hair stand up on my neck.  My biggest single phobia about cycling is a tire failure at speed. 

I know there's all kinds of other stuff to be worried about; drivers, deer, engine seize...  but the tire one is definitely top of my list.  I think it's probably because I feel that my riding skill gives me a fighting chance against those other hazards.  I had a back tire blow at 55 mph with my wife on the back once.  I kept us from going down, but it scared the crap out of me.  Had it been the front tire, we probably would have been toast.   :o

I contacted Bike Bandit, where I bought the tires. They is still on record. Help dude said to please send in photos of the tires with more details. They want to show the pictures to the manufacturer to see what they think.  :(

There may be some hope after all.

In the mean time, I'm ordering a new set of rubbers for the C10.
I'm not gonna sit idle while the tire gods make a determination.

Sound promising and a good way to roll. Keep us posted on the outcome.  :popcorn:

Most likely it is ozone damage from warehouse being too close to a freeway with the doors open. Another reason to convert to 17 inch tires is that they will usually not sit on the shelf too long since most modern bikes have 17's. My last set of 17's were 2 months old when I recieved them. I would not ride around the block with a tire that looks like that.

Still waiting to hear back from the manufacturer.

In the mean time, new tires arrived. Putting them on this weekend.  :)

Why not say who made the tire? Maybe others would like to inspect their own tires. I have never had that problem with Pirelli or Michelin. I had a set for three years once and no problem. Most of the time one or two years. And...no, it's not safe. That tire is toast! Could be a new cartoon....

I didn't want to mention the tire and start some kind of tire war of sorts. To me, it doesn't matter. Rubber is rubber, but if you want to know, it was set of Pirelli tires.

I have Pirellis on my bike and am interested to check them out. Date codes were good but they were CHEAP. Thanks for sharing and glad you didn't ride on it anymore.

I don't see where anyone has mentioned this but have you been running at the recommended tire pressure? Since the defect is localized at the edge of the rim I wonder if it was run at too low a pressure and possibly combined with a heavy load. Ozone degradation would not be location specific and you would see it all over the tire (I believe).

Dan,

Good question, but the answer is no. The tire was ridden at the correct pressure by a light rider, my son who weighs less than me. Also, the bags were removed, so the bike was ridden lighter than normal. When I ride it, it usually is on the heavier side. For air pressure, I use a very accurate digital gauge accurate to 1/10 psi. It doesn't get hot here in Casper, WY and at my altitude (over a mile high), I usually give it an extra psi. The tire arrived just before winter, installed, then parked for the winter. It just doesn't get that hot here where I live. That tire has less than 100 miles on it.  :(

In this case, that tire is definitely defective. Wow!

Someone I know had a tire degrade during winter storage. The tire dealer asked where he stored the bike, he said in the garage in a new location near a refrigerator. Not sure how true but the tire dealer said that the motor of the refrigerator will cause the tire to degrade, who knew.

Still no reply from Bike Bandit.

Not sure what to do. I'll make one more call and if I don't get any help (or the same help) I've been getting, then no more business from me, ever.   :(

If I treated my customers like I've been treated, I'd be fired by now.
