Longitudinal Split in Bridgestone G547

[Flexit]

Morning all, so here's a new on to me. In Jan 25 I had a new (but bought a couple a years ago) G547 fitted to my outfit and it has covered 2,000 miles to date. As anyone watching me will have seen I recently had work done to the cooling system of my 1990 ST1100 and as the weather was forecast to be half decent yesterday I thought I'd take the old lady for a run out.

However, during my pre-ride scan I just spotted what looks like a longitudinal split in the centre tread, it goes about 30cm/1 foot around thetyre. I have used G547s for virtually all the bikes 168,000 miles and never experienced this before. Anyone seen anything similar. The tyres DOT indicates manufactured Jul/Aug 2020. We are suffering a bad epidemic of potholes here in the UK, but it's impossible to say if that had any effect!

According to the thread profile is this a G547 Exedra... (and I never had one failing... ever...)

BT57 look like this:

Oh Dear, Thank you for the correction. Must not have slept well last night! G547 it is and Thread Title and mail duly amended. And, Like you, I have never ever had a problem with these tyres in 30 years of use, hence the question

I'd check age/production date and speed index first... maybe you've been sold a "shelf-queen"...
The tire doesn't look old, good chances to claim an FOC replacement at the dealer...

Glad you caught that. The importance of pre-flight checks, which I'll admit I'm guilty of sometimes skipping.

It must have been fate. Normally I would just leap on (well clamber on!) and go, but I was just doing a tyre pressure check when I saw it

Yikes - that could have been a really bad event!
Glad you caught it in time.

Good catch! I am not sure I would have spotted that at all. Now I will be more vigilant on my pre-ride checks. Thanks for posting this.

Have you rode in cold weather?

Wow, I have never heard of anything like that happening on a tire that’s less than six years old!!

I am willing to ride on some pretty bad tires,
but I don’t think I would ride on one that’s beginning to split itself in half, and is already a quarter of the way there!!
