Is this tire safe to ride on?
 

I put this set of Michelin Krylion Carbons on about 500 miles ago and had my first flat two days ago. It had just rained and all the road junk was sticking to my tire. I actually had to dig out the embedded shard of stone that was lodged in the tire. They are also starting the "square off" considerably. I ride at maximun PSI and am wondering if this tire need to be replaced or if I should continue to ride on it? I was thinking of replacing them with either the Vittoria Rubino Pro Slick or the Continental Grand Prix 4000s.

Does the hole go all the way through the tire? Does the tube poke out when you inflate it? If not, I'd ride it.

I'd just replace the tire without analyzing it too much - it is about $40 anyway, especially if it is on the front.

Same here. I'd just replace it citing my "If you have to ask...." rule.
I don't think saving a few bucks is worth always wondering if your tire is going to explode. I'd just replace it.

I would replace it immediately. It sucks being out in the middle of nowhere with a split tire.

Good point, though the only reason I am questioning it is because I won't replace just one. I don't want to continue to use that same make/model of tire and to change over to a new set would be $75-100.

I will just switch it to the front and ride it till it explodes.

Of course it is safe to ride on....save it for your trainer.

It is about as close to all the way through as you can get without actually being there.

Looks like this is the winner.

The wife just called and said she would rather me spend $100 than to have to get out of bed on a Saturday morning at 6am to come get me off the side of the road.

So now which set do you guys think would be better the Vittoria Rubino Pro Slick or the Continental Grand Prix 4000s?

That is nothing. Even if it goes all the way through, just put a glueless patch on the inside of the tire so it doesn't mess your tube up, and expect to get another 1000 miles out of these tires.

I replaced mine with four similar sized holes.

Not worth the risk.

I have read that the Michelin Krylions (as well as Vredestein tires) "ain't what they used to be" after moving production to Asia. Can anyone speak from personal experience on this?

I have Rubino Pros and I have Conti 4000S. I like both, but prefer the Continentals. The Rubinos are much tougher, though, and seem to last forever.

You heard wrong...personal experience plus some of my friends.

most people are so paranoid.

I would ride it but I am cheap and like to get every penny out of things I buy. I would just keep an eye out for any enlargement of the hole under pressure and use. I might also use a boot to support the area.

+1

While I was changing the rear to the front so I can "make do" until next week when I can get new tires, I noticed the sidewall on the front tire is cracked and has separated so that I can see whatever layer is red within these tires. I can say that I won't be purchasing these tires ever again. A puncture, my fault no biggie. A sidewall close to failure after 500 miles at 115 psi.... it doesn't inspire much confidence in the brand.

ooooh, are we comparing scars?

I'll see your hole and raise you some crookedness ;)

replaced this last night

Wasn't the hole on the back tire? Why move it to the front? You want your best tire on the front. When my back tire is worn out, I move the old front to the back, and put the new tire on the front.

I was going to move it to the front because I weigh 205 and I figure it would have been too much pressure on the already damaged tire. Now that I know the integrity of both tires are compromised this entire discussion is moot. I have placed the order for the Vittoria Rubino Pro Slicks. So much for riding this weekend.

I'd be poor if I replaced every tire that had a cut like that....and I get them at wholesale.

Ride it. If it freaks you out then just keep an eye on it. You will either get more flats quickly or it will slowly start to bulge (over many rides) if that cut is truly through the cords and begins to propagate. It isn't going to leave you stranded from the looks of it. I can assure you I probably have 3 or 4 mounted and currently ridden tires that have multiple cuts that look like that with no issues.

For those of you who recommended to absolutely swap it out.....have you seen my website? :)

Never move a suspect tire to the front.

:roflmao2:

I would put a boot on it and move it to the back. Good as new.
