Michelin Road 5

1/4 cup is my fav !!

@Kiwifruit how are the PR5's going?

I'm due for a new front (and have only recently put a new PR4 on the rear) but wondering whether to go a PR4 or PR5 on the front.
Thoughts?

I wouldn't think there'd be any compatibility issues with mixing them.

@Tony Nitrous any thoughts and who would you recommend to buy and fit one from?

Cheers lads

or Vlad, you could get some Angels, have Really good tyres.

[Kiwifruit]

Really like them. Done a few rides in heavy rain. Feel sure footed. The people at the little bike shop l use have a couple of their own bikes shod with them.
Dont see why you would have compatibility issues. The 5's are just next generation technology.

According to Michelin you can mix them. See attached document.

Just had a set of Road 5's fitted Saturday - $520 AUD fitted. I've been through PR 2s, 3s, and several sets of 4s already. Wasn't an ideal day yesterday for scrubbing in - wet/damp greasy roads (some with a distinctly greenish mossy tinge out of the car wheel lines) but put in a couple of hundred kms or so on the back roads out through Gembrook, Hoddles Creek, Healesville, Kinglake with lunch and a couple of beers at St Andrews pub.
Have to say I'm impressed - even with the usual improvement apparent with any new rubber, these things are awesome - easily scraping my boots with full confidence even in those very ordinary conditions.
Assuming they last as long as the PR 4s did (and according to the blurb should be no issues with that) I'm a fan!
I'm playing the front pressure a bit by trial - I've found with the PR 4s the front needed to be 40-42 psi to avoid scrubbing out the right hand side of the tyre really quickly - have set this one at 38 for now and will be keeping a close eye on it.

@black14 its funny you should say that. I have been running  mine at around 38 and indeed it is the RHS of the tyre which has scrubbed out earlier. I don't go through THAT many roundabouts that that should be a factor, so I assume its simply to with the typical road camber.

[KiwiCol]

My 4's did the same thing, chewed out the rhs of the tyre first, quite noticeably too. I used to run 36-38 in it too. 

When I put the angels on, bloke in the bike shop said it'd be beneficial to run a couple of lb higher front & rear, heavy guy & heavy (ish) bike, so I do now, for both of them. 38-40 in front & 40-42 in rear.

I think there's more to it than road camber Vlad...

All tyres, particularly the front, wear more on the right hand side (left in other countries where they drive on the wrong side of the road!) due both to the camber and the fact that when driving on the left side of the road all the right handers are correspondingly longer (assuming all bends left and right average out to equal radius) so the tyre spends more time on the right side than the left.

But (for example) the PR2s don't do it to anywhere near the extent of the PR4s (running less than 40 psi).

I think it has to do with those fine sipes (learnt that word from the tyre ads!) that run essentially at right angles to the tyre on the PR 4s - causes the rubber to "feather" and wear. I don't really have an explanation for why more on the right hand side other than there is more right hand wear anyway so any accelerated wear is compounding.

I've no idea if this is also a symptom of heavy bike/heavy rider, riding style or just the tyre construction/tread but I would prefer to run the front at 36/38 rather then 40/42 like I have been on the PR 4s for many years (doesn't seem to impact grip but does make the front end feel a little harsh).

As the Road 5s have a different tread pattern - not so many fine sipes - I will leave it at 38 in the front for now and keep a close eye on it - previous experience tells me that once that wear pattern sets in it cannot be reversed and the front tyre life is significantly shortened.

my last angel wore out front rhs. i use 36psi. was just on 20th ks but.

[Kiwifruit]

I tend to run pressures on the lower side. 36F 38R around town. My reasoning being, more rubber on the road and tyre heats up quicker. With pillion or luggage l go to 38 40.
Being dual compound tyres the shoulders are a lot softer and wear quicker than the centre. Certainly camber can play a big part in the life of a tyre. Suspension setup can also have an impact on wear.
The PR4 front that l took off was not worn out but was worn enough to not want to pair up with a new rear. I now use it for putting my wheels on when i'm doing maintainence on them. Without air in the wear on both the left and right sides of that  tyre is quite pronounced.

[Hooli]

My PR4s wear a lot worse on the right of the front tyre too, I got it with the PR2s/PR3s as well but it seems more noticeable on the 4s. I should be trying 5s next time I get a pair so we'll see.

[grog]

Kiwi, i might be wrong but only rear is dual compound, Michy n Pirelli.

[Hooli]

Dual compounds at both ends from what I can find on google https://www.motorcyclistonline.com/news/michelin-pilot-road-4#page-3

[Kiwifruit]

PR4 front and rear are Dual Compound.
