Michelin Tyre Oozing Pink Stuff

[nickvink30@yahoo.com]

So I was wondering if anybody else has seen this happen to their Michelin Tyres.

 

I fitted these late Dec and they've started oozing this weird pink rubbery stuff. Have no idea if its a defect or what and am worried about the tyres integrity if I remove it? Furthermore, it doesn't look all that appealing.

 

The tyres in question are Michelin Pro 4 Endurance.

 

I tried taking it up with the supplier but no response as yet.

 

Has this happened to any of you and is there cause for concern?

Looks like sealant seeping out the sidewalls. 

 

Have you taken it up with your LBS?

Hi DR. No sealant present in tyres, I'm running with tubes.

Never seen anything like it before and I've used many brands (including Michelin in the past).

Oh wow. That is super odd. 

 

This is a first for me too. Who did you buy these from?

[nickvink30@yahoo.com]

The online store called Cyclesharp. Have had great service from them over the years

Apparently its not uncommon with these. Michelin has in the pasy responded that its a pre treatment sprayed onto the under layers before the final top layer is applied and vulcanized. If they get it wrong, too much is applied and can ooze out like this. Apparently only affects very small batches, and is nothing to worry about from their view, and anecdotal evidence from people who've had the same issue...

Quick google, some say it is a bonding sealant of the tyre construction

It is Michelin's effort to raise breast cancer awareness

Thanks Butterbean. I want to scrape it off as it looks so wrong. Still a little concerned about sidewall integrity though as it will remove this "bonding" material. Had i known this would happen I doubt I would have purchased.

Anybody know who the distributors are? I'm keen to take it up with them.

Just chat to the shop you bought them from. They must sort you out.

I was going to make a crack about the OP's wheelset being gay, but thought better of it.

My bother had a set that did exactly the same thing. He took them back to Cycle Lab and they swapped them out for another brand for him.
