Every rated 37x12.50R18 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, it uses that one.
- Ranking
- A score backed by only a few reviews or tests is pulled toward the typical score before ranking, so a 95 from a dozen reviews can rank below a 92 from hundreds.

What rims fit 37x12.50R18 tires?
A tire fits a range of rim widths. Too narrow or too wide and the sidewall changes shape.
The rim diameter is fixed at 18″; only the width can change. Rims are usually 70–90% as wide as the tire’s 12.5″ section width.
Some factory fitments sit outside that range: 18x8.5. Check the rim width approved for your car before you buy.
