Michelin PR'2 question

[panman40]

Hi,
I had a Pr'2 put on the rear of my ST1300 last week and have covered 1300mls since while on holiday.
There is a thin shallow line running around the circumference of the tyre which you can just about feel with your nail,almost like a "Seam",
I have not had this on any tyre before.

Has anyone else experianced this or is it more likely a "Faulty" tyre ?,

thanks,

Martin.

Martin, I have an old brain and I'm running Storms now, but on my PR's (not the new PR2) there was a line like you describe. Do the PR2's roar like the old ones?

There is a little Hum at 60-62 mph ish but nothing I have noticed apart from that, the line is a little bit "Squiggly" rather than perfectly straight !

I had it that line on both sets of Pilot roads I ran. And now have it on the PR2's I am running. Don't know what causes it but I have never had a problem from it.

 

[panman40]

Well thats really interesting!!, I think I will give Michelin a call tomorrow

Could it be a seam where the 2 tire compounds are brought together?

Could be on the PR2's, but the Pilot Roads were not a dual compound.

BT020Fs have the same thing. I wrote Bridgestone about it, and they said it's an identification marker they use as a safety check to make sure the tires have the right compounds in them.

I have had several 020 F's but never had the line on them or any other tyre before, Weird !

I went out and looked at the rear tire this morning and sure enough, there is a thin line in the center of the tire. Considering that I now have over 12K miles on it I'm not going to worry about it now!

I had a photo of the lines but must not have saved it. I'm about due up for tires, so when the new set arrives, I'll snap another picture.

I noticed the line on the PR2's I mounted for WeSTOC. I don't know what or why it's there but over 4K miles and no issues. I don't notice a hum when riding straight but do pick one up when I lean it into a turn. Nothing bad, just noticeable.

 

[Caper]

I've seen the line on every Pilot Road I've looked at. Don't know if it's correct or not, but I was told by a Michelin Rep that the line is there to dissipate static electric charge.

 

[panman40]

Yep "Caper" was correct ,

I spoke to michelin UK today and straight away the guy said i'ts a built in to the tyre to dissipate static charge , something to do with modern m/cycles having so many electronic devices,

Many thanks to everyone for the replys

Just insyalled a set pf PR2's, got a GIVI 52 box, anyone notice handeling problems and what tire pressure ? They feel squirrely.

I don't notice anything squirrely. I have the hondaline top box. I run 42psi front and back.

 

[harleyeater]

Have not had them wet yet, any problems, thanks:bow1:

 

[Landon]

No problems for me in the rain.

 

[harleyeater]

Thanks for the info, leaving July 5 for 12 days to the left coast and do not have a lot of miles on them, new brand for me other than stock tires, little nervous about them.

 

[Landon]

You will be fine. This is the third set of Pilot Roads for me. First set of PR2's and I have about 4500 miles on them....look like they may go another 8 pretty easy. To bad you are leaving or you could join me and some others from the site for a ride on the 6th. I leave thursday to head to Colorado for 10 days.
