Every rated 255/30R20 tire, by season

Ranked by our Relative score, weighed against how many reviews and tests stand behind it.

How scores work
Relative score
0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
Ranking
The score already allows for how much stands behind it: with only a few reviews or tests a tire stays near the typical score. Among similar scores, newer tires rank higher and tires replaced by a newer generation lower.
