Every Yokohama tire line in this table (18 of 747 total lines), with each line's UTQG treadwear, traction, and temperature grade, sorted by treadwear.

		UTQG traction grade: AA (best), A, B, C — wet straight-line stopping distance	UTQG temperature grade: A (best), B, C — heat resistance at speed	Manufacturer's own comparative wear number vs. its reference tire — comparable within one brand, rough guide across brands	Number of size/construction entries found for this line in the source mirror	true if different sizes of this line carry different UTQG grades — shown grade is the most common

About this data

This is a filtered view of Passenger Tire UTQG Grades (747 rows). UTQG grades (treadwear/traction/temperature) originate from NHTSA's Uniform Tire Quality Grading System, a public-domain federal dataset — but the grades themselves are self-reported by tire manufacturers under NHTSA's mandated test procedure; NHTSA spot-checks compliance rather than running independent tests. NHTSA's own consumer lookup tool (safercar.gov/Vehicle+Shoppers/Tires+Rating) returned an Akamai 403 on a plain-HTTP fetch and was not retried; data.transportation.gov's Socrata catalog entries for this dataset (sku7-utyd, rfqx-2vcg) are non-tabular stubs whose .csv resource endpoints also 403. This table is compiled from vehicletire.com's brand-by-brand transcription of the same federal database (raw HTML archived in research/2026-07-19-tires-utqg/raw/), covering 11 major brands only — other brands were not in the fetchable mirror and are a recorded miss, not a substitution. Where a tire line's grade varies by size or construction, the most common combination across that line's listed sizes is shown (flagged per-row in "varies"); the sidewall grade on the exact size purchased always governs. Generated 2026-07-19 by pipeline/tires/utqg-to-dataset.ts from data/sources/nhtsa-utqg.csv (1,863 raw size/construction lines, collapsed to 747 tire lines).
