Are these tires safe?

I put a pair of new Classicride 28x1,6 tires on my bike and after a few miles they started to get these long tears on the sidewall around the reflective part. Unfortunately I can not upload pictures because I am new. According to the recommended pressure on the tire, I did not over inflate them. Are these tires defective? I unfortunately can not return them so I'm also wondering if they are still safe to ride?

Rim brakes? Make sure the pads aren’t touching the tires when applied.

That looks like an old tire that has been degraded from environmental conditions. I can only say that I would be skeptical about riding on these tires. I cannot tell from the just the pictures, but to my eye, the separation looks pretty serious.

It gets back to whether the inside fabric is damaged or not. At this stage, it is probably not. I would run them at a bit lower pressure, and keep an eye on them. It might go in the future.

I would be wary of doing high speed down hill. If one did fail at high speed, it may be serious.

In future buy a different brand of tires.

Thanks for the replies! I'll keep an eye on them and not do anything crazy.

What do they look like on the inside of the tire? If the casing looks ok, I'd say that what you see on the outside is not a big deal. Can you return them to the vendor? If they are new, you have a good argument that they have a defect.

This edge cracking is one of the issues with reflective side wall strips. Was so in the late 1970s when there was a movement to require new bikes to be so equipped (thanks to a few smart advocates, spoke reflectors were still allowed) and still is currently. As mentioned, unless there's casing cord damage these cracks are unsightly at worst. Since they are usually found on rather thicker side walled tires and these tires generally have fairly thick casing cords there's usually no long term issue. Andy

Andrew,
I enjoy hearing from someone with a knowledge base that is grounded having paid attention to this stuff or a long time. You should take over maintanence and updating of Sheldon Brown's site!

Just be ready to walk home. Or, make sure to take your phone & a $20 bill for a cab ride home. Be good. Have fun.

No thanks. My cousin John A does a good job helping this out already. Andy

There are some serious quality control issues there.
I would not ride on those tires, unless it was only on level ground (NO DOWNHILLS) and below about 12 MPH.
That is serious for that to be on any new tire, even if in storage for as much as a decade.
I have briefly ridden aboard 40+ year old tires on the first few days of acquiring some old bicycle for a shakedown/test ride before installing brand new tires.
Those 40+ year old tires which I wouldn't ride for more than two miles before replacing looked to be a heck of a lot better than those shown above.

That is also absolutely untrue with respect to the reflective sidewalls on quality bicycle tire brands.
I have MICHELIN PROTEK ( 32-630 , 27 x 1 1/4) on several of my vintage Schwinns.
These MICHELIN PROTEK tires have among one of the best and most visible refelective sidewall rings and the tires still look factory perfect even after more than 1100 miles.

Riding severely aged tires, as many in the classic heavyweight balloon tire and antique beach cruiser crowd does can be hazardous to your health if for example you should be on a significant downhill ride during the Summertime heat and the tread carcass separates like what happens sometimes on the interstate to aged tractor-trailer tires. I'm sure you've at least seen the portions of the tread scraps littering the highway if you've never actually seen it occur on the interstate.
Yeah, if the tread carcass separates just enough that the inner tube begins to protrude/escape the tire cover, you'll likely have a blowout of the innertube within ten seconds and that ballon-burst situation of instantaneous massive deflation will have you on potentially the scariest and potentially the most painful crash ride of your life!
You could end up with a broken clavicle, broken rib(s), broken wrist, broken arm, broken elbow, broken ankle, broken kneecap, or broken leg, concussion, cracked skull, broken jaw, or just lose a few teeth and road rash.
Hopefully, you never ever have a crash but trust me when I say that it is not fun. $45 or so for decent tires is far better than your out of pocket portion for the orthopaedic surgeon's bill, the anesthesiologists bill, the medical facility's outpatient surgery bill, the physical theraphy bill and not to mention the long uncomfortable 8 to 10 weeks of mending after the crash and surgery............sleeping propped up or in a recliner chair for a while, and then the long struggle with physical theraphy in getting range of motion and overall function restored as much as possible. Sure, you have a tale to tell at airport screenings and at anyplace that employs metal detectors like concerts and goverment office buildings and courthouses.
..............................So Much Is Riding On Your Tires!!!
......Wear a helmet!
Make certain that your bicycle is properly adjusted and good to go BEFORE embarking on any ride. If you can't do the adjustments properly, then take your bike to a professional at the local bike shop. It is well worth it.
Now, if you simply make a mistake and crash at 28mph while making a sharp right turn while training for IRONMAN 70.3 and it's 56 mile bike course..........well as they say -it- happens...............accidents can and do happen from rider error when everything else----the bike, the weather, the roadsurface, is perfect.................you just don't want something much more probable.......... There is maybe zero risk in riding that on level pavement at low speed but think about it before you take it downhill during Summertime heat. ................Do you feel lucky? Feelin' lucky might not be enough, that is why most of us old farts who didn't wear helmets during the 1940's, 1950's, 1960's and 1970's are wearing helmets today. We don't expect that we'll ever put the helmet to the test but it is there on our head if we do need to find out. We do see that things could be potentially really bad if we were without head protection and our head just barely glances or kisses the pavement. The risk/benefit decision is something to certainly consider. I'm sorry that you cannot either return those tires for refund as no new tire should appear to be that degraded. You might be out the return shipping (cost to send them back). Maybe perhaps you can have your credit card issuer reverse the charge based on the unuseable goods that you will return to the seller. That tire just looks too bad to be a brand new tire that is worth trusting on a downhill ride.
