Do I need additional tools to use these irons?

You'll want a tire machine or second set of hands to hold the wheel steady while you work. The irons themselves are standalone — no pneumatic power required. A bead breaker tool is separate if you're starting from a tight seal.

Will this kit scratch my wheels?

The bead keeper is specifically designed to protect rim edges during demount. Use it as shown to keep tire beads off the lip. Pad your iron tips with tape if working on polished or custom wheels to add an extra layer of safety.

What size tires can these handle?

These are standard tire irons scaled for passenger and light truck applications. Very large diameter or ultra-stiff sidewall tires may require additional leverage or specialized tools — test on your specific tire before committing to the full job.
