Glyn this was my reply to Sharpo about my experiance with a 180 compared to a 190 rear tyre,plus and little about "pushing it"
You may of noticed that I had a 180 rear on at Cadwell and not my previous 190 that is f you could of got close enough

"Pushing the front" thats when you go into a corner a bit too hot/fast and still be on the front brake ,your'e then "pushing the front" tyre to its limit of adession and a possible spill.
The 180 is the width of the rear tyre (180mm) with a 180 on the rear your front tyre will turn quicker into a corner and lean over in comparison to the width of the rear tyre thus the "Chicken" strip ( where the tyre has not been used)will be wider, but closer to the edge on the rear
With a 190 mm rear tyre because its wider you find the front is slower to turn in and will wear nearer to the edge , as you are trying to overcome the extra width of the rear . Sounds complicated you need to see it more than talk about it. Hope that makes sense

With the 190 on the back I think you will see less wear on the front edges

Hmm, pushing the front is where your transferring your body weight under braking through your arms (which generally are locked) to the bars and down to the front wheel, hence pushing.

Pushing the suspension down just works against the fork spring and it "pushes" back against you, I doubt you can press a fork enough to compress it enough to have an effect on the wheel, if you did it would be bottomed out and more than likely the front wheel is losing tyre contact and bouncing, hardly what you want mid corner. you can load the front more with your bodyweight being transerred forward but that is not pushing the front ,it alters weight distribution and the rear will slide easier because there is less eight over it. As fordie says its when the tyre starts to lose grip you asre pushing the limits of tyre adhesion, typically downhill corners or holding too much front brake too late, its about slip, contact patch and grip not where you push.
