I'm looking at getting some Metzler M77R's fitted on my T595 soon, anyone know what they're like fresh on?
They are just fine! All these scare stories here...
I have used them for the last 5 years on my CBR600F4i, changing sometimes twice a year.
First sensation on new M7RR is that the bike falls into corners much faster, which can surprise in roundabouts if one is not prepared for that.
F4i is a barge compared to my 2014 Daytona 675, which has very fast handling, but on fresh M7RR Honda behaves like Daytona for a little while.
Otherwise just go out and ride your heart out.

100miles?!
tell me about it! 100 damn miles! I then rather "scrub" the tires with the sandpaper in 5 minutes and be done with it. smile
Put the tires on, check the pressure, and start leaning progressively right from the start, on dry surface, of course. That's it.

Mildly related, but do bike tyres ‘go off’?

I’ve got a pair on my Aprilia that were there when I bought the thing, so at least 4 years old. I don’t do many miles on it though, so they are still absolutely fine from a tread/wear perspective...I just sometimes feel that they feel a bit slippy but not sure whether it’s just my imagination or not.

Presumably if they’re otherwise ok, age doesn’t really matter?
They do. These are my 9 year old tyres which started this whole thread because I need to get them replaced ASAP



Note the cracks in the tread. The rubber also seems way too firm. Even on the motorway for an hour the tyres never get very hot and you can barely leave a finger nail imprint in the rubber (should be tacky almost like chewing gum).
Thanks EasyDuz and Zakalwe. Interesting stuff - will take another look at mine and see...

Last time I got tyres fitted they were Angel STs on a VFR and a FireBlade. On the VFR they felt fine from the word go, on the Blade it felt like I was riding around on big ten bob bits for a canny few miles. Heavier VFR but wider tyres on FireBlade. So my answer is - I don't know. confused

I put a Motoz Rallz on the back of my Africa Twin a few weeks ago. Leaving the garage was a right turn onto the main road. Wasn't doing anything daft and the bike did 90degrees on the spot - closest I've ever come to dropping it on the road! . A few miles later they were fine but for sure - should have paid more attention - so yes - scrubbing in should still be a thing, even if only a short ride.

Michelin and continental seem good from the off. The Metzelers I tried were awful for about 100miles
How were they "awful"? I'm intrigued.

Stand it upright out of the tyre shop and rip it in first, that's the centre scrubbed. 10 miles on an A-road adding speed and lean, gradually. That's the sides. Job done.

Felt slippery and twitchy for what seemed like forever. The back came around on me at the 1st junction from home at a fairly sedate pace. Never gelled with them and didn’t trust them.Luckily they only lasted a month/ 700 miles and I ditched them.

Based on the replies im just going to take some 180 grit sandpaper with me and scrub them down before leaving. Not worth the risk.

There really is no need, just ride carefully on the fking things for 10 miles or so.

Yes, that is the one and only solution.
Get the smallest grit sandpaper and do the job properly, do not miss any spots on the tire, center or sides, otherwise the first ride on them slippery new tires will be your last fo sho!

Apparently its tyre brand dependant. Dont think anyone has mentioned Bridgestones yet so cant say if they are slippy when new but its a no brainer really.

1. Scrub the tyres with sand paper. Time taken: 5 minutes. Cost: 0
2. Ride straight away, risk dropping the bike at low or high speed. Cost: Anywhere from £0 to £1000's.

It would appear that the quiet haven that was BB is becoming more and more like the open forums on PH, sandpaper?????????????? get a grip you plank, I'd recommend that anyone considering using sandpaper to 'scrub' tyres should really step away from the bike and hand the keys in to a dealer, if you are not capable of moderating lean and throttle position for a few miles you should not be riding a fking bike, I have never heard anything so pathetic as fking sandpapering your new tyres, I'd love you to stand outside FWR or any other ride in/ride out tyre place and hand out sandpaper to people, you'd be laughed off the face of the earth.

Couple of first hand examples of tyre scrubbing: -

Dave Jefferies, you may recall being a legendary TT rider before his untimely death, his dad's bike shop many years ago, punter had some new tyres fitted but it was raining, Dave jumped on his bike and buggered off, came back edge to edge scrubbed in.

Many years ago in my short racing career we were using stock Pirelli Diablo tyres (road tyres as a control tyre), no tyre warmers just straight out on track. It was qualifying at Donny one of the top guys had fitted new tyres and he went off like a scalded cat from the pits, the first turn - Redgate he was knee down never to be seen again that session.

Whereas I still tend to do a few miles on the road just to be sure in my own head.

This bit has me confused...do you mean he fked off and was never caught or do you mean he wasn't seen again in the session because he binned it in the kitty litter at Redgate...?

No he just buggered off, he was that confident and fast new tyres or not, he won that years championship by some margin.

Not upset, just amazed at some of the crap people post, BN broke his hip highsiding off his drive, Mr OCD also crashed on his drive, because they were setting off on cold tyres and were a bit clumsy with the throttle, so going by your logic I guess you'd better use tyre warmers before every ride, or just take a bit of care.

fking sandpaper...................

hmm... so I could sit outside Watling Tyres with a cordless sander, offering to 'scrub' in at a tenner a tyre.

Tsk, where's the fun in that though ;-)

There's always someone who's good for binning it in the summer turning right onto the main road. Normally this is predicted by the staff :-)
