Highest treadwear grades NHTSA lists

Not every line is in the file
NHTSA's published UTQG list is not exhaustive. Some lines are missing from the file. This page does not invent a grade for a missing line. Absence is not a grade, and it does not say the tire is unsold. Why a tire may have no UTQG rating. Lines the grade guide calls out. Lines this file does not contain.
UTQG treadwear is a comparative rating under 49 CFR 575.104. A higher number means a slower wear rate on the government test course. It is not miles, and grades from different brands are only loosely comparable. This page lists usable grade rows whose treadwear is 800 or above. A row with treadwear 0, no treadwear number, a treadwear value that is not a whole number, or a traction or temperature letter outside the usual grades is left out. Those rows stay on the tire-line page. The usual traction letters are AA, A, B, and C. The usual temperature letters are A, B, and C.
NHTSA lists Hankook iON HT at 900 (1 row listed as all sizes), Bridgestone ECOPIA EP150 at 880 (1 size-specific row), Hankook KInERGy PT at 860 and 800 (2 size-specific rows and 1 row listed as all sizes), Michelin Defender 2 at 840 (1 row listed as all sizes), and Michelin X Tour A/S 2 at 840 (1 row listed as all sizes) in this pull. A watched name that is not in the file, or that has no usable treadwear of 800 or above, is left out.
A line with a higher treadwear number comes before a line with a lower one, and lines with the same number are ordered by brand and line. A row does not mean the tire is on sale. The table links hide rows outside the usual grades.

Grade rows
Each row is a size series NHTSA published. The size text is shown as stored. A row is all sizes only when that text, with extra spaces collapsed, is “all”, “all size”, or “all sizes”. Any other text is size-specific. The tire-line link opens every size series on that line.

Lines where the grade differs by size
A line is listed here when usable treadwear or traction has more than one value, after flagged rows are left out. The link opens the note on the tire-line page. Other usable treadwear is a number on that line below 800. “None” means every usable treadwear number on the line is in the table above. Why treadwear can differ by size.

Questions
What is the highest treadwear grade NHTSA lists?
The highest treadwear in NHTSA's published UTQG list is 900, on Hankook iON HT. NHTSA lists that grade on 1 grade row.
Does a treadwear grade say how far the tire will travel?
No. Treadwear is a relative grade under 49 CFR 575.104, from a government test course, not miles. NHTSA's file does not turn that number into a distance.
Is every high-treadwear tire in this list?
No. NHTSA's published UTQG list is not exhaustive. Some lines are missing from the file. This page does not invent a grade for a missing line, and absence is not a grade.
What does size-specific mean on this page?
NHTSA stores a size series on each grade row. A row is size-specific unless the size text, with extra spaces collapsed, is all, all size, or all sizes. The grade molded on the sidewall of the tire you buy is the grade for that tire.
Why can one tire line list more than one treadwear grade?
NHTSA lists a treadwear number on each size row. Another size of the same line can carry a different number. The grade molded on the sidewall of the tire you buy is the grade for that tire.
