Michelin Pilot Power 3 - Update

Just thought I'd give you a quick update on the Michelin Pilot Power 3's that I put on the R1 last tyre change. I now have done about 5000km's on these tyres without any real problems so to speak. The PP3 is Michelin's 2CT dual compound  sports tyre, which is a harder compound in the centre with a soft compound on the side where you need it most - in the middle of a bend you certainly want the soft sticky bits to keep you firmly planted to the road.

As the tyre has aged I've really started to notice the pronounced difference in the 2 compounds where they join, it has clearly become visible. Another slightly more alarming thing that I've noticed is that when I run my fingers across the join in the 2 compounds you can feel a dip in the tread ever so slightly, it's probably about a millimetre in difference. Now I haven't really noticed this whilst cranked over hooking into a bend at speed, but it will be interesting to see how much this wears over the last 1000km's of its life span which is probably about all I will get out of it. I'll post up a bit more on these tyres later when I finish this set off.

  1. hmmm... that's a little concerning chillertek. :/ you would think they'd have their use of dual compounds mastered? but clearly not... i'll be following your updates on this!

  2. I don't think I've seen dual compounds wear quite that way before.

    As long as they don't separate and you can't feel it in the corners you'll probably be okay for the rest of the life of the tire. Keep us posted.

    1. I haven't noticed this happen to the previous michelins I've had before and they were dual compound. It must be just how they made these particular tyres.

  3. Steve, I've never seen the difference in the two compounds like that on the Michelin Pilot Road 3's (sport-TOURING tire) that I used. However, my newish PR4 on the front is starting to cup, just like the previous PR3 did. I'm really fussy about tire pressures and check them before every ride. Anyway, I'm going to take it back to my tire guy within the next week just to give him some feedback on the PR4's.

    I think I'm just about over Michelin's sport-touring tires and will probably give Pirelli Angel's a go next time.

    1. Yeah it's really pronounced isn't it. I had Pilot Power Pures and Pilot Power 2's on before these tyres and they never did this before either. I am also thinking of trying something else next time. I'll see how they go.

      How many km's are on the PR4. It's no a good sign if its cupping already.

  5. Look like different UV fade rates to me.
