Tyre life

I have never subscribed to the five year tyre life, seems I might have been right.

I’m struggling to get a season out of my tyres. Five years or aged tyres are off my radar.

Well there you have it, 'cos bloke on YouTube said so.

Reasonable arguments presented but then uses 7 year properly stored tyres, which doesn't reflect the state of a 7 year old used tyre.
He does go on to point out the difference but doesn't put any figures on it, so I reckon we're back to square one?

I personally don't have any bother wearing out tyres in much less than 5 years, and always make sure I buy recent date stamps.
The problem comes when buying a second hand bike. Usually they are described as "having plenty of tread" or "3000 miles left in them" and so on.
When asked for the date stamps they are frequently from way back and could have been stored in any manner of horrendous conditions.

I recently looked at an ST2 with "plenty of tread left". My lovely little LED inspection lamp revealed date stamps nine years old! (and a floppy horrid chain among other things!)
It's a good excuse to roll my eyes and tut to get the price down a bit, but I would change them anyway. You have to trust the seller to give you the date stamps if you're buying on the internet and it's it's not always negotiable anyway.. You pays yer money...

What YouTube guy doesn't tell you is that the elements that give you good wet grip are the perishable ones (silicates It think?).

I'll stick with my own 5 year rule.

My front Michelin PR4 looks like it will never wear out! I think I'm 4 years in and very little wear, the rear PR3 has done about 10k in 7 years. I'm only changing the rear to a PR5 as it's meant to be a better tyre.

Is 1700-1800 miles out of a set before they’re trashed good?

Lol!

No danger of old tyres on my 1200R, it bloody eats the things! Lol!

Not bad, when I was much younger I had a Jota that would eat a Pirelli phantom in about 1500 miles.
Then I also had a race tuned TZR250 that didn't really do that much better but that used to get mercilessly thrashed.
Old tech tyres though, all single compound so sticky = wear

I had a similar experience as my Cagiva Mito used tyres quicker than my Fireblade… bonkers!

My M900 gets through rear tyres (and chains) much faster than my 916 despite being around 30hp down.

Originally I fitted it with the same Diablo Rosso tyres and it munched through it the rear in half the mileage so I fitted the less sporty Angel GTs which last better but still less than the Rossos do on the 916.

Down to power delivery and riding style I guess.

But I've never had to worry about tyres that were 5 (or more) years old...
