Hi all,
I put a set of Michelin PR4 tyres on the ST on June 22nd.
First photo is on Aug 9th at 10,000 kms.
Second photos are on Aug 18th at 15,000 kms.
Third photos are on Aug 30th at 20,000 kms.
Note: Not too many windy roads on this trip

Great stuff mccarthy - thanks for sharing. ++
Always interested to know what mileage Members are getting from their hoops, and what sorts of roads/riding style they do it on.
Cheers, Diesel

Third photo of the rear shows it's down to the indicator on the right side, but there's plenty of tread left on the left. Damn that road camber... :well
I therefore disagree with Brock, and think the tyre is close to the end of it's legal life.

Nothing a hot soldering iron with a scooped tip wouldnt fix Pete

You may be on to something Brock. :crackup Back in the old days, it was considered OK to re-groove worn out tyres, and I'm not talking about retreads. >:()

Did the ST get new shoes for the BDR to "The Rock"??

Hi John
I put a new front tyre on before we left replacing the one that went around Oz 33,000 kms. My back tyre had done 8,500 kms so it had enough in it. The rear will be replaced fairly soon after 6,000 kms to the Rock. I have ridden a few more corners so won't go quite as far.

Thanks for the info. Hope the Red Centre ride went well.
How far did the back BDRAA tyre go, before being replaced?
Have you continued with PR4's?
The picture of the front tyre at 20,000km seems to have a nail head showing???
(http://"S:\Data - Motorcycling\ST1300 info\OzSTOC\MMs front tyre at 20000km.jpg")
My 2nd ST actually has PR3's on it that are getting to look a bit sad, and the bike only has about 24,000km on it, some of which were probably on the original Bridgestone BT020's. I have a half worn rear Bridgestone Exedra Max left over from my BDRAA trip, so will get that fitted for a start then have to choose which way to go after that.
My CBR1000F has the Bridgestone BT023 tyres on it and they seem to work quite well up here when pushed. They might not be much good down your way, though, as they seem a bit too hard for the cold wet weather. (especially like we had coming out of Bateau Bay and Glen Innes last year)
We've both got our leave applications in (mine has already been approved) and the boat trips are booked, so we plan to see you in Feb/Mar 2016, if not sooner.
Regards
John

We had a cooler ride to the centre this year. We had some rain later in the day coming into Clare SA. From Port Augusta to Coober Pedy we had a fairly strong side wind that kept things interesting. Only had the liner out of my jacket for 4 days out of the 14 days we were away.
My rear tyre from around Oz was changed at 24,000 kms and changed the front after 33,000 kms.
That must be a small pebble in the tread, didn't have any punctures.
I have put the Michelin PR4 tyres on again. They feel great in the corners and get good mileage so no reason to change.
I'm looking forward to catching up when you are over. If you need accommodation in Launceston you are more than welcome to stay.
Cheers mate

My current PR4s are just down to the wear bars after 16,000+ km. Going to organise some more and be more careful with tyre pursues.
-
"be more careful with tyre pursues." :o
Let us know how that goes.
-
Well I can't get new PR4s, :( so tomorrow I get new PR3s.

The PR3's are probably old stock, so I'd be ordering PR4's and waiting a few days.

I normally would JC, but I'm heading off on a 5,200+ km ride Thursday morning.

Pretty impressive demo.
I wonder where you find a strip of epoxy long enough to conduct a braking test?
-
At a Dekra Test Centre track.

Well that escalated quickly. When the wheels came off, it became very obvious that the front and rear brake pads were down to less than 1 mm of wear left.
So while they were at it I asked them to do an oil and filter change in preparation for the big ride.
$795.00 = 3 x brake pad sets, brake fluid, new PR3s, fitting, balancing, labour and workshop consumables and most importantly SWMBO is less stressed about my big ride and I'm very happy.

It seems that the revamped, dual compound, Metzeler Z8's have upstaged the other Sport Touring tyres, according to Motorrad.
This is the final result of the comparative which saw the success of the Metzeler Roadtec Z8 INTERACT followed by Pirelli Angel GT tied with Michelin Pilot Road 4 GT, and all other participant tyres following:
•1. Metzeler ROADTEC Z8 INTERACT
•2. Pirelli Angel GT
•2. Michelin Pilot Road 4 GT
•4. Bridgestone Battlax T30 EVO
•5. Dunlop Sportmax RoadSmart II
•6. Continental Road Attack 2 GT

hey Guys looking around Brisbane and trying getting a Michelin Pilot Road 4 but the book says 17 inch front and mine is 18nch making it more expensive is this just a one off or are the shops taking the piss out of me I been quoted $250 just for the front ? my current tyres are front 12/70 18 rear 170/60 17

Try TeamMoto Moorooka I just replaced a rear at a cost of $260

Found a set of PR 4 at Motorcycle Tyre warehouse at Brendale going to get them fitted now https://motorcycletyrewarehouse.com.au/ (https://motorcycletyrewarehouse.com.au/)

That's a bargain from them!
I got my Oxford hot grips there and their quote for tyres was higher than my regular supplier in Brendale.
I guess it's because they are superseded that they have that great PR3 special on their website revolving banner.

My front is 120/70 18, $245.00 (PR4)

set of PR4 here in Brissy for $449 fitted. saw them on the weekend

18" front wheels/tyres are the original fitment for the ST's

I did a few short trips in the last couple of weeks, about 2500k in total, and in that time, it seems the rear PR3 wore a lot more than the previous 5000ks. Not complaining as I got between 15 and 20 thou out of them on both my ST's, but it was a bit embarrassing as I just had a rego check and didn't check the rear tyre before I took it in.... :-[
My previous set of Michelins on my MT01 wore incredibly quick in the last 500k's, but that was a much light tyre, but it's got me wondering about the last part of a tyres life. It seems to go from being OK to very marginal in a relatively short period of time, so it just makes me more careful about recording distances and keeping a close eye on tyre wear, particularly rears, as the tyres come to the end of their lives.
Another observation that I've made over time is that cold to hot pressure increases for rear tyres are double that of the front tyres - depending on the ambient temps, rears go from 42 psi up to sometimes over 52psi, and fronts are lucky to hit 47psi hot. Also, temp increases are way more in the rear tyre from the front tyre as well. In 30deg heat, rear tyre has seen over 55deg, and fronts about 10 deg lower. The lesson for me is to spend the time monitoring the rear tyre over the front, as it is far easier to look at the front than to get down and have a good look at the rear, particularly if you have a towbar and mudflap blocking your view. :-[
I was going to order a set of Pirelli GT's but having a closer look at them, they don't appear to make an "A" version in ST sizes, which is most likely not going to be a problem, as many have used them on heavy bikes like the ST with great results for both grip and wear, but as PR4's are available with a heavier carcass for heavier bikes like the ST, I ordered a set of them. I also just checked the Pirelli website and they actually say they don't make a Angel GT to suit! :eek Even though they make the correct sizes for the ST, they don't recommend running them? That's interesting.... :think1 They don't seem to make any tyre to suit an ST, and the only size that will fit the ST isn't recommended??
Whilst I've had no problems with standard PR2's and 3's, I wanted to try a tyre designed for a heavier bike and compare the difference, so hopefully, these new PR4's will feel as good as the PR3's, and I'll be taking notice of the pressure and temp increases in the rear to see if they are significantly lower than the PR3's.

On the strength of a hint from the Forum, I went from 42 front and rear, to 42 front and 44 rear. This has extended my PR tyre life by around 4,000km and I now get around 22,000 from a set. Hot pressures rise by 5-8psi depending mainly upon the heat of the day. (Garmin Tyre Pressure Monitors)
On the matter of tyre wear in the last part of a tyre's life, I recall reading, or having it explained in this way.... When a tyre is newer, the rubber is thicker and there is more flex within the depth of the rubber through the contact patch. When the tyre is worn, the rubber of the contact patch is thinner, there is far less flex to absorb irregularities through the depth of the rubber, and hence it wears quicker. It could be bull@#$%, but it sounded reasonable to me.

I was happy with the PR4s I had and was disappointed I couldn't get another set, but the PR3s were a good fallback.

On occasions, I've also upped my rear tyre pressure to 44 as well, but I was doing this the same time as I was playing with the damping on the rear shock, so probably can't draw conclusions about the ride quality, but I'm sure that you are correct with the extra mileage you get from them.
Interestingly, a rep selling Michelins was in the shop this morning when I was there, and looking at the previous set of PR3's and my old set of Dunlops, he highly recommended the GT version of the PR4's for the ST, as he made some interesting observations on the wear characteristics of both sets my old tyres, particularly about the cupping in the tread front and rear, and the "gumballing" on both sides of the rear. Reckons the heavier carcass will suit the ST perfectly, so I guess I'll find out soon :whistle

The tyre shops here recommend the GT as well. They seem to be working for me

The GTs worked for me.

...it's got nothing to do with the road camber - that's just a myth.
