Tyre issue?

[SPP]

It isn't that cut and dry. The main difference between sports tyres and road tyres is the operating temperature. Sports tyres are generally stickier when hot, but not as good when cold, and compared to road tyres, have a narrower operating temperature range. We are not talking big differences here as the manufacturers know that sports tyres are also going to be used on the road, but still a noticeable effect. This does not reflect pure race tyres which have to be kept really warm to work correctly.

If your riding style is rapid acceleration and hard braking, accompanied by vigorous cornering then sportier tyres should be your choice. If your riding is smoother and and more relaxed over longer distances then more road oriented should be your choice.

My own underwhelming experiences with ST tyres a matter of riding style? I hear what you’re saying and it does make sense. I don’t I ride particularly strong on the street but I’m not smooth and flowy either so could be.

It doesn't look shiny except for about the last 15mm on each side as I haven't had it leaned over far yet.[/QUOTE]
pffff

road riding can bring slips and slides at any/every corner/hillcrest.
Good work putting your foot down, that's why great quality riding boots were invented.
probs saved an ankle right there
Reactions and ATGATT are there to save your ass, you will meet the circumstances where all of your best skills and precautions meet all the most unlucky/unlikely conditions at least once in your riding existence. DAMHIK
Tyres (and suspension) are about the relationship between you and the road. Not TRUST, do not TRUST a certain tyre to save your ass. *Rant over*

You have answered your own question. PP3, not PR3, needs to be kept hot to obtain its grip. I am often amazed at the number of riders who expect sport tyres to give the same amount of grip as road tyres in slow cold conditions. Unless you are riding hard, in dry conditions, then a road tyre will give better grip. Its when you are pushing hard, and the tyre is hot, that sports tyres come into their own.

Never had issues with my Supercorsa soft compounds in the wet.

I've got a Michelin PP 2CT on the rear, and had a normal PP on the front before, and never had any problems with grip even when riding gently.

Check your tyre pressures but it does sound like shit (diesel/oil) on the road

[spanner spinner]

use to sell motorcycle tyres for a living and have sold thousands of different tyres of different brands and this is normal for Michelin sport tyres in the wet, they are very sensitive to tyre temperature and don't work when cold. this is from both personal experience and feed back from customers. If you want a good wet weather sport tyre buy Dunlop.

Not always true. My Pilot Powers offer more grip in any road condition than any other tyres I have owned. They just don't last very long

Had Pilot road 2's on my blackbird, scrubbed them in, in the wet from Auckland to Welli...they were great, a lot better than the shit avon storms I had on. I have found best wet grip though to come from bridgestones.....bt-023 battlax is amazing for wet road touring.

I have run Michelin Pilot Power 2 2ct, Power Pures 2ct, and now pilot power 3(front only).

I have always scrubbed them in. A minimum of 200km, at least.

I have never had an issue, unless it was caused by shit on the road.

This includes a ride Christmas day Auckland to Wanganui, in rather consistent rain.

The front tyre was less than 500km old.

worth checking your tyre pressures - I have had tyres put on by shops before who blew 'em up wayyy to high (for me - theres a bit of preference involved with 'correct' pressures).
The pressures will affect how quick, and how much it warms up - higher pressure warms up slower, holds less heat, lower pressures the opposite, ut wears faster. Even if pressures are correct, how long had you been riding for, and at what pace? as mentioned the tyre might not have been up to operating temperature.

other things to consider are that there could have been oil deisel, or any kind of other shit on the road surface that had an effect.

oh, and heavy rain (IMO) isnt so bad, as HEAVY rain washes the road somewhat, but light rain, seems to lift the grime and oil and fuel and shit dripped on the road from the crevices between the chip and brings it to the surface affecting grip.

simplest stuff first, go check your pressures and doesnt hurt to re-evaluate suspension settings either.

clear as mud?

[kinger]

Quadruple the distance and I'd understand the confusion.

[gwynfryn]

The only times i have lost the front on the road was in winter with a pilot power on the front ! Stick with a pilot road.

I'm running 36psi front and 38psi rear (cold) so that's not an issue. I had been riding for about 10 minutes before this happened, at a faster pace than what I was riding when I slipped. There was heavy rain in the days before and on the day this happened, so any diesel or oil should have been washed away. I didn't see any gravel.

SMOKEU's, what sort of bike to you have?

I'm with SPP. At 30km/h the bike is going to have very little lean angle. Even with the tyres stone cold you are not going to have a grip issue.

My bet is there was something on the road surface.

1997 GSXR600. I have included a Google Maps image of the corner. I was travelling down hill.

...that bit of the road is notorious for diesel spills from campers and gherkins in Merivale shopping carts, thinking they are real cool whizzing round the bendy bits...the rain was on and off over the period you were riding, with high humidity...add the frantic pre christmas shopping trips for aforementioned bints in their shopping carts and an added litre or two of diesel slopping out 'cos they all filled up down in the city, so they would have enough juice over the imagined closed for christmas period...hey presto...slippy tyre...imo...
