My rear will wear right to the edge, but even after serious decking of the pegs/ crash bungs( track day last sept ), where the absolute limit of lean angle was explored...the front will still have tread left on the front. As such , you can take it as read that you wont ever get the front tyre edge " scrubbed in" ...unless the bike is sliding down the road !
On the road it will be just odd occasions you will scrape the pegs , maybe as much from suspension compressing after a sharp turn in, as actually requiring that amount of lean. For some time I never got the pegs down after fitting weight balanced suspension, but now can do so regularly. But the bike dont really want to go too far past this as if something solid hits down,then it will either bounce the bike off line or even lift tyre off the road....both will be bad !
So my advice is ...dont worry about it , just ride the bike as you want ,
cheers
