front tyre issues
Im out half way through cleaning my bike as i type this.
So for a while i'v thought the front end to be a bit 'skitty' like its not quite going to stick if i ride any harder round the corners, which is odd as its only started happening since i replaced the rear tyre, prior to this its was spot on to be honest! Now, as im cleaning her, i have a good look over the front tyre, it seems that the bit 'that isnt the centre and isnt the outside (the bit in between) has worn hell of a lot, almost no visible tread! therefore i had like a shoulder on the rims of my tyre about 1cm from the edge, all the way round, both sides. Is this the way im riding? or the bike? Im running pilot road ones at the moment, jacked up 45mm at the rear, and dropped about 5mm through the yokes. Hope this makes sence...... Cheers, Sam

Re: front tyre issues
Is the pressure right? Maybe needs 1 or 2 more psi.

Re: front tyre issues
As above really, except the "skittish" feel actually comes from an increased contact patch, not a reduced one. The way the tyre wears flattens off the profile so that you end up with a V shape instead of a nice new rounded one. This means that when the bike is leant over onto the flat bit it will track on any road surface imperfection a whole lot more (just like wide low profile tyres do on cars) giving the horrible feeling you describe.

Re: front tyre issues
Reducing the steering head angle by the drastic amount you have is going to have a negative effect on tyre wear as well, because you've put so much more weight over the front and the tyre is working harder mid corner.

Re: front tyre issues
I think you have described a worn out tyre.Replace it and the handling will be transformed.
