what sort of milage are people getting from p3' please
previous rear p3. 24000 km
present front p3 26000km will need another soon
-
I'm past 12K. Tyres are looking good. I have a PR2/PR3 combo.
:blu13

25K from last rear PR3. Had PR2 on the front for 29K
Now have PR3 F&R - will let you know - so far 5K on rear on loooong flat outback roads - stood up real well. :thumb
Looks like there is a PR3 drought on in Oz - very hard to find ATM - just ask IanB! :eek
Cheers, Diesel

I think they are a victim of their own success. 24K km is unheard of for most bike tyres. Many of us have been getting half that from other tyres.
Hopefully Michelin will catch up with the supply and not tamper with the recipe. It would be terrible if it was a short run of a particularly good material and from the next batch it's back to 12K tyre life. :(

You can get them from Jake Wilson , I have ordered a set of p3 for mine. If I can get the same sort of k's as you Diesel I will be happy. Unless you put your bike in the trailer :well :well going to try the dyana beads for balance and a pair of 45 degree valve stems. :blk13l

... If I can get the same sort of k's as you Diesel I will be happy. .. going to try the dyna beads for balance and a pair of 45 degree valve stems.
Yeah - good call Adam. My only secret is to keep constant tyre pressures. This is made easier by my 90* valve stem fillers as I am quite anal vigilant about checking them before each outing. (42/44psi by MY gauge).
I believe dyna beads would only enhance the longevity of the tyre too. :thumbs
Cheers, Diesel
PS: I should point out that I have one of these bad boys constantly at the ready to add a few lbs in if nec. .....

You are a mobile garage. If i ride with you I wouldn't need to bring anything. Would get a few more ks out of a tank :think1 being lighter. :thumb :blk13
-
Just took del of my p3 today from Jake Wilson. If I can get Diesel's type of k's out of them I will be happy. Will fit them next week with dyna beads in them. I got 13 k's out of my bridgestone 021 :blk13
-
If you got 13Ks out of the BT021 then it is likely you will get a lot more out of the PR3s. I got 7Ks out of a front BT021.

But you've got to be using Diesel's magic tyre pressure gauge!

Very true ol mate - that is what works for me under MY conditions. I've often thought to benchmark it against others' gauges - and to make sure I benchmark again my next gauge (since I've found the 'sweet spot)' :thumb

New PR3 rear just fitted at Tyres for Bikes (Vic Park) 14700Ks on the 026
-
Just had front and rear PR3s fitted and a major service (including valves) done by South City Honda in Mandurah, total cost of $1300 was less than expected. :thumbsup
The old PR3s had done about 18,000 and still had maybe another 3 or 4000klm left in them. :runyay
:grin :blk13 :grin
-
I finally got a front PR3. Had to go to Jake Wilson in the States but not unhappy abt that. Landed in mapleton it cost $191.
fitting at $30 and I'm on par with SE Qld prices. And ordered on a wednesday and fitted to bike the following Wed. Michelin can't even tell us when the next boatload will arrive.
Stuck the required 42 in them and went for the circuit yesterday. Most noticeable thing was the ride feel very harsh.
My circuit is Mapleton, Maleny, Kenilworth then up hill back into Mapleton. Nice easy 85km break from the drudgery (eat yer hearts out city dwellers.)
PR2 ride felt a bit softer and more in contact with road. By that I don't mean the newies feel dangerous, just less confidence building due to the lack of feel.
Mary Valley festival is on at Kadanga today so will recheck the pressures and go do the loop again with a detour and see if anything changes.
-
Try knocking it back to 40 psi, may make the world of difference
-
Sounds like you might need to play around with tyre pressures relative to the PR2.
-
Hmmmm.... :think1
Looks like this is a job for Diesel and his amazing Michelin tyre 'life extenda' tyre pressure gauge!
Problem is that, even though we both have Candy ST13s and ride the same Sunshine Coast Hinterland roads in the same climate etc etc, Beatup (wringing wet) weighs only approximately the same as my left leg! So this could be a challenge! :rofl
On a more serious note champ - try bedding them in for another 50-100kms. I have just gone through the same PR2 to 3 change on all the above listed similar environmental conditions and have found them easily as good as the PR2s. Better? Yet to be seen. As good? Definitely. Remember you are coming off a shot front to a brand spanker, so there is bound to be an initial difference in your expected perceptions of tyre behaviour.
Oh - and where are the pics of the 'swooping' episodes involving ST1300s and ST1100s near your place? :well
Hope this helps.
Cheers, Diesel

Yep, will persevere, not a lot of choice.
But the strange thing is that the ride now seems harsher since the 3 has gone on the front.
Didn't have a problem when it was 2 upfront and 3 on back.
Tried to give the back a pizzling and it felt good through the Dulong bends but now the trundler goes where it's pointed but with less feel.
Will fiddle abt and see what we have. Perhaps someones gauge ain't accurate.
And some of the maggie pics are fine but need a bit of photoshop. Shadow under the trees are a bit darker than anticiapted and need softening to let the black of the wings stand out. Me don't know how to do.
-
Time to give up on this tyre pressure stuff for a while.
Went for a trundle today and wasn't happy vegemite.
Met with GURU, The Diesel, and played on the roads.
The 3's still felt hard. Almost convinced the front slid a little through a right hander.
Got the pressure gauge out at a hydrate stop. Mine read 40 but on the same gauge Diesel's read 48 in the front
Then we checked Diesels with his gauge, 42 and mine 36. Went to servo pumped up to 46 front and back.
Got home, gauge read 42, older digital gauge read 44.6.
Query to self- if mine are/were grossly under inflated how come they feel harder than the 2's.
Felt a bit better at the alleged 46 but that could have been cause I was playing on home turf, corners travelled often.
Going away for a few days bikeless to the big burgh of Melbourne.
Will start this experiment on Saturday when get back.
-
Off topic, but...................
Perhaps since I weigh abt the same as your thigh, I actually feel more of what is happening on the bike instead of weighing it down and forcing it into the road.
Wait till it's my turn to take your pic - might only be of a thigh you cheeky bugger.
-
I am driving down to Melbourne on the Saturday for a week, so we will probably cross paths on the way. Managed to score a luxury 2 bedroom unit on the 9th floor at Docklands for $500 the week.

It can be a little awe-inspiring this pressure thing - but we showed that yours and my gauge had a 6-8lb psi difference. And you got yet another reading on your digital one at home. I'm not saying my gauge is correct - but I do know that if I had let 6-8lbs out of my front tyre to make it read 42psi on your gauge - it would have felt spongey, lazy, and slow turning.
At least you know that I run 48psi front and 50psi rear according to your gauge if you want a benchmark.
It was a lot of fun researching this. Funny how the laboratory is usually great roads ending at a pub. :rofl :beer
Cheers, Diesel
-
Looks like a gauge of known accuracy is needed for comparison. At least then you would know what your own gauge should read for the correct pressure.
-
I bought a new guage from supercheap that Choice had tested as being accurate (in fact most of the guages they tested were with 1 psi or so of true). The new guage showed that my pencil guage I carry on the bike reads 1 psi low, and my other digital gauge 3 psi low. I prefer reading a bit low as a bit more pressure is better than too little. So my 36 front 42 rear pressures are really 37/43. Allan's suggestion (now Brock's as well as my typing is slow!) of dropping into a tyre place to check against their calibrated gauge might be a good idea to see what pressures really are. As long as a gauge is consistent that is important.

Based on feedback I've seen here in these forums I'd like to get me a pair of PR3 tyres for my ST1100.
Just looking at the Michelin brochure I don't see a 160/70 ZR17 (73W) even mentioned :eek
Am I missing something here?
In my defence:
1. I took a man look :o
2. I'm tired :crazy
3. I have headache that's been getting worse for hours :||||
In need of some of these :beer

No you haven't missed anything.........Only Avon and Bridgestone still have 160/70ZR17 tyres to suit 1100 OEM tyre specs.
Usually a 160/60 tyre gets fitted but the 170/60 tyre (1300) shouldn't be a problem.
-
If you want the PR3, you will have to get a 170/60 rear, which works fine (it is ST13 size) - the 160/60 makes the rear sit a bit too low for my liking. If a 110/80 x 18 front is not available, a 120/70 x 18 works fine as well (later ABS bikes uses the wider front tyre anyway, but has a wider rim as well)
-
Ah, thanks for that.
Would like to retain the OEM tyre size.
With reports of the Avons delaminating and the police using the Z6 tyres I guess I'll go for those.
I did find the Metzeler Z6 tyres available via Ebay:
At your door for $US 157.55

Mech, have just fitted a 170/60 to my 1100 and still plenty of room. Same OD as the 160/70.
Read your ebay site again, $79.99 for postage!!! That makes it dearer than the local ones.

And you can do what I did and fitted a 180 /60 - 17 on my 1100 and yes they do fit very easily.

Just looking at what that means: http://www.tacomaworld.com/forum/tirecalc.php?tires=160-70r17-180-60r17 (http://www.tacomaworld.com/forum/tirecalc.php?tires=160-70r17-180-60r17)
It looks like a better fit than the 170/60 option.

well I am very happy with the PR3's :grin :grin :grin

Tipsy,
Can you do a visual check on your rear tyre for me? Is it a 180/60 or a 180/55?
-
I have used a few Avons over the years and had zero problems. I would not hesitate to use them again, but availabilty and the price compared to others I get from www.jakewilson.com (http://www.jakewilson.com) are now factors (and I think that rear would be a 180/55 but it must be a 'narrow' one as I had a 170/60 that was a real tight squeeze to fit)
-
I'll stick with Bridgestone 023's in the original sizes. No-one has yet been able to tell me definitively what effect different rear tyre sizes will have on the ABS operation. I know the difference between 170/60 and 160/70 is 3% (170 slightly smaller) but how much will the ABS cope with? Is there an expert out there who will definitively say the ABS computer won't have a problem when it's needed.

As tipsy has done a PR3 in 180/55/17 fits fine on the St1100 no problem with removing and replacing easy fit just makes the bike stand up more upright on the side stand
-
I don't have ABS to worry about but I will try to stick with OEM sizes.
The Metzeler Z6, Bridgestone or Dunlop are my only options.
-
My new PR3 rear is a 170/60 ZR 17

Looks like Dunlop has released a tyre in 1100 sizes which they dropped in the Roadsmart 1 series.

I tried the first Roadsmart and it was nothing special. It is ok though, but no more.
I have used non-OEM size front and back on non-ABS over the years with no issues. Brand and type of tyre seems to be more of an issue than size.
