That could make it even more boring in terms of a race. If tire wear doesn't matter and it basically becomes an engine contest you'll know even sooner than you do now who will win the race. Give everyone the same engine though and it gets more interesting, but that's probably not what the biggest teams want to do as their dominance and likelihood in winning the constructor's money would decline. There need to be more variables not less if you want more interesting races.
