First the good news - passed the MOT this morning.

However performing a a 90 degrees turn the rear stepped out a good foot and I wasn't even gassing it. Tyres only done 15 miles, were cold, conditions wet. Also managed to spin the back up around 40mph going in a straight line.

The back also stepped out leaving the Ace on Sunday and it was warm and sunny.

I hope it's just a case of a having a lot of torque or the release compund not having worn off. Should I have stuck to the trusty BT020s?

Ive had a similar problem withg my new tyres Julian. Thye took a good 100 miles to get a reaction in the rubber. I think its much more likely to be a combination of the cold weather and low miles.

Ive been too "sesible" with tyre choice this time. The front is an Avon Azaro SP and the rear an ST. Im well happy with the front, but so far as yet the rear hasnt inspired complete confidence. It's hard to tell yet though, as there are still patches of raod with salt residue etc

Julian - take the bike out to J2 of the M40 and do a few laps of the roundabout; it's surfaced with Shellgrip.

Don't recommend doing it the other way though to get the l/h side scuffed up

just do a couple of fast exits....

Take a look here for a technical Bridgestone write-up.

They don't use release agents apparently and it details why you should run your tyres in.

I know it's on the Fazer forum (don't ask) but interesting nonetheless.

The tyre I wrote my S off on was a new rear 020!!

Slippery Bridgestone release compound?

I,ve just about half way scrubbing my new set in.

Hi Julian

I'm not sure if your takeing the piss!!! 15 miles?? their bound to be slippy your looking at at least 100 miles minimum,if i had a pound for every muppet that has ridden out of Central Wheel after being told to scrub e'm in and take it steady,and then gone and dumped it on the floor 20 yards from the door i'd be rich,the last one i saw was a ZX9 and it had punched a hole through the engine cover.

I only had the same conversation with Gus last week,scrubing tyres in is my pet hate had 014's put on last week just made sure i'd got some heat into e'm before i did anything daft,and the way thing are going will have to do the rest on the way to Le-Mans next week and will have to do the same if we go on the Tiger cuz thats got a new 014 on the front as well.

Chris I always take it easy on new tyres for at least 60 miles, honest guv, but but these hoops are like slippery eels. Never known anything like it. Maybe I cant handle a big bike after pootling round on the tractor for a year - either that or gotten used to the Avon Azaro/Proextreme Wets.

Hi Julian

You'll need to do 60 miles to get some heat into the tyres at this time of year,never scrubbing e'm in 60 miles,even unoffically your talking 200 and while i've no people do it in less,don't be suprised if you end up on your ear!!,it's getting releaseing agent out e'm thats the trouble and don't believe the bollocks about not useing it,they'd never get the buggers out of the mould if they didn't.

Modern, silica-based rubber doesn't need release agent Anyway, if a tyre company claimed they didn't use it and in fact had, and someone did have grounds for litigation, the consequences would be terrifying.

Edit (sorry): Adam - excellent link.

Bryn Phillips did a superb article on the VFR (cough spit) forum a while back which made fascinating reading. I met him at an Ally Pally show 3 years ago and he's a top bloke - very informative and blows a lot of bullshit out of the water when it comes to talking tyres.

Julian mate, you might have been on some old diesel or anything - the roads round here are certainly still not clean anyway. We've had a fair bit of rain by I still had some (what felt like) slides with the front last week mid journey.

I still reckon that 010's etc are unnecessary for road riding - they never get warm enough (especially at this time of year - you walk round on the road with no shoes on and see how cold it is) and wear out/square off too quickly. The sports touring jobbies are a much more sensible bet I reckon nowadays and still let the bike corner on it's ear - what more is required - horses for courses I guess though.

Glad to hear it's back on the road - look forward to seeing it in the flesh next weekend maybe

First impressions of the 014's:

Nice tyre - definitely quicker steering than the 010 and light on its feet. Not a murmur in the slippy-slidy dept either, just take it really easy until the centre tread's built up a bit of scuffing then build it up from there

Just need to run-in the brand new 010's on the TT now

Hi Julian


I've a granny in the Coop who knows loads about tyres!!!!! she says you can call the release agent any old bollocks you like for legal purposes,but it's the crap that comes out of the tyre when new,(hence why any decent shop wipes e'm down with a fast evaporateing liquid)of course if you like to buy a pair of tyre warmers just like all those racers use down at Thruxton today it would save you all that time fannying about putting lots of miles on!!!

And just to give you some idea of the dilema tyre manafactures have,my man today(Thruxton) goes out on a tyre slightly different from what he used yesterday because the tempreture has change it's no where near as good,hence why at this time of year unless you've done a zillion miles to warm the tyres up you've no idea how good or bad they are.
