Get your self a slide hammer 100x easier breaking the beads then using hammer and Steel or hammer and TL but when I did commercial I used a slide hammer and when braking the beads on a 445/45r19.5 they are so much easier and less afford in breaking the beads
Not much point with a 600nm torque wrench after you twat the living shite out of it with a 1500ftlb impact wrench. Never understand why tyre fitters bother with a torque wrench.
