Michelin PR2 - easy to spin up in the wet or past it?

[banditrider]

7,000 odd kms on my first set and still plenty left. Thinking I'll get 11k which puts them on par with a set of Pirelli Stradas I had. Not bad for 280kg bike with plenty of ergs. Only time I've spun the rear with the PR2's is when playing the fool...

I have the same problem with my PR2. this is my first winter on it they loose alot. At first i thought it has something to with my SAG settings.

[sharky]

hey thanks.

All of your bikes have much more torque, and they work for you!

I'm gonna drop the pressures some more and maybe try to sit back a little.

Cheers

It is a bit of a common mis-conception that you should drop your pressures back in the wet to allow them to heat up more. What also happens is the tyre deforms more, effectively squashing the grooves closer together so they don't disperse the water as well.
I'm running PR2's on the road bike. I reckon 34 front, 38 rear.

Suspension: i haven't changed any setting. It feels ok but i honestly wouldn't know.

Giving it stick it the wet: Not really, I shit myself too much.

Wear: I’ve attached pictures of the tyres which have 15,000km now. Tread depth looks ok to me. Only slight flattening on the rear and the front (right side) is slightly chiselled.

Pressures: Dropped them to 32/32 this morning but the jury is still out. It felt kinda funky

What now… I pumped them up to 34/38 (cold?) and will try again. Worst case scenario is that I’ve had 15k out of a set tyres. That’s a pretty good worst case I reckon.

Cheers all

holy shit. they look like a new set!

[cowboyz]

BTW. If you do decide to change them out. I will buy your old set off you

I have PR2s on a little CBR 600RR with 15,000 km on them. They look just less than half worn (really hard wearing on a light bike!)

In the wet/rain these spin up and step out A LOT more than I thought they would especially considering the CBR is hardly a torque monster and I'm not really giving it heaps

e.g.
• 95-100k not accelerating and going uphill in 6th. Road was smooth perhaps a little tar bleed. Rear stepped out to 4 o'clock but no fish tailing.
• 60-70k, 3/4 acceleration (2nd or 3rd). Road was smooth but no lines or tar bleed. Fish tailing 4 O'clock to 4 O' clock a number of times. I really thought somebody was going to ram me from behind

Unintentional spin up a few times now. Is this normal for PR2 or are they just past it? Is the bike too light to get these to grip properly? Harden up mate its all part of the fun?

I’m considering changing to BT016 or Powers. I think want sport tyres again.

Note: The OEM BT015 that were on it last winter spun up maybe once or twice in the wet but only mildly and always stayed straight. Never once did they suddenly let go and step out and I’m riding the same roads.

I got PR2's fitted to my old ZZR600 because they are supposed to be good in the wet. I can spin mine up in the wet when accelerateing hard , get it to fish tail when going over lines and the back to lock up when braking hard. The Metzelers I had on the back were worse and I could lock it up in the dry. One important factor I think is my suspension is past its best and the front is very soft ( something I'm working on). It may pay to check your suspension settings. Start at the standard settings and only change one thing at a time,setting up the correct amount of sag is a good starting point. I'm no expert so it pays to get some help from a pro before meddling with settings and totally stuffing up everything.

P.S. glad to hear they are so long lasting.

Ye dropping tyre pressures slightly should help to. Good luck on getting it sorted.

Man - I'm looking forward to getting 15,000 out of mine now!

Can I suggest you try 32/35.

holy shit. they look like a new set!

That they do. Almost as tho they've never been asked to do any 'real' work.
Maybe that's the problem?
Another thing...what's the manufacture date? There will be some numbers inside a little circle on one sidewall of each tyre. What are they?

I have a stepping out issue with my pp.

I'm running a pp front and a pp2ct rear. Compared to the conti roads I was running these feel pretty loose in the wet.

The front steps out a lot, pretty much every ride in the wet ,and I don't feel overly confident on them, and yes I'm used to riding in all weather (only transport).

In the dry they are bloody good but gimme back my conti roads in the wet anyday!!!

[Gremlin]

Crikey, they look fantastic for 15,000km...

I'm with MSTRS, and the suspension settings... Hell, my CB900 only got 16,000km odd , and they had completely squared off (almost entirely commuting), nothing left in the middle...

It took a hell of a lot to make the tyre break free, usually stupid stuff like deliberately unloading it then jumping on the brakes

I'd stay away from 016 in the wet, I suspect they completely let go when I was doing 68kph, no warning, splat, I'm sliding... gentle corner and all that.

This is on your hornet 900? What tyre pressures?

I've always been a huge fan of Pirrelli Diablo's, but on this bike they would get chewed up too quickly. However, having run battleaxe's on the GSXR (and when they let go, it wasn't nice), have now got PR2's and am impressed with both wet and dry riding - feel very confident on them. And we rode in torrential rain the other day, and I still managed a constant speed of around 90-100 km between Wairoa and Napier
