Correct answer
Make sure the tyre tread depth is never less than 1.6 mm.
Keep tyres in good condition with at least 1.6 mm in the principal tread grooves, the regulatory minimum for this category. Tread helps disperse water, but meeting the minimum does not guarantee good grip in all conditions. Recommended pressure, damage, speed and road condition also matter. Do not arbitrarily increase pressure or mix tyre constructions contrary to vehicle approval and specifications.
