How the Pirelli Diablo Rosso IV performs. It does not lead any single category outright in this matchup. It has limited comparative test data, so treat its results as indicative.
What this means for you.

Also check that both tires are actually offered in your size and load rating: performance can shift between sizes, and availability differs between the European and North American markets.
