Tire Sizes on New Vehicles: What the Factory Data Shows
Which tire sizes do carmakers actually fit to new vehicles? We counted the sizes in 6,137 trim listings that we verified against carmaker documents. Every figure below is calculated from that data when the site is built.
Data as of October 2026.
Key findings
- The data holds 6,137 trim listings (a trim listing is one trim of one model year with one size) across 5,081 trims, 203 models and 27 makes, model years 2002 to 2027, with 192 distinct sizes.
- 235/55R19 is the most common size, on 239 trim listings (3.9%) and 24 models. The ten most common sizes together account for 26.0% of listings.
- 18-inch wheels are the most common group (29.0% of listings); wheels of 20 inches and larger make up 25.5%.
- Among model years with at least 100 listings, the average wheel diameter is 17.5 inches for 2017 and 19.0 inches for 2027. Coverage differs by model year, so this describes the data we hold, not the whole market.
- 7.4% of listings are LT (light truck) sizes, spread across 19 distinct sizes.
- 1.7% of trims (84 of 5,081) have a staggered fitment, with different front and rear sizes.
- 1 flotation size (written in inches, like 37x12.50R17) appears on 9 listings.
- Nominal overall diameter runs from 23.7 in (195/50R16, for example the 2025 Mazda MX-5 Miata Sport) to 37.0 in (37x12.50R17, for example the 2027 Ford F-150 Raptor).

Two ways to rank sizes. Counting trim listings shows how often a size appears; counting models shows how many different vehicles use it. Each size links to its own page.

Average wheel diameter by model year
The mean wheel diameter of all trim listings in each model year, with the number of listings (n). Only model years with at least 100 listings are shown; 2002 (n = 30), 2003 (n = 35), 2004 (n = 35), 2005 (n = 31), 2006 (n = 34), 2007 (n = 52), 2008 (n = 50), 2009 (n = 59), 2010 (n = 60), 2011 (n = 55), 2012 (n = 77), 2013 (n = 87), 2014 (n = 87), 2015 (n = 96), 2016 (n = 93), 2018 (n = 99), 2019 (n = 84) have too few. Bars start at zero.
- 201717.50 inn = 100
- 202017.96 inn = 558
- 202118.05 inn = 537

How much of each make and model we have verified differs from year to year, so a change between years can reflect which vehicles are in the data as well as what carmakers fit.
Light truck, staggered and flotation sizes
- LT (light truck) sizes
- 7.4%
- 453 listings, 19 sizes
- trims with a staggered fitment
- 1.7%
- 84 of 5,081 trims
- flotation sizes
- 1
- 9 listings
LT sizes carry the LT marking in the size. Staggered means the front and rear tires are different sizes. Flotation sizes give the overall diameter and width in inches, like 37x12.50R17.
By make
The most common size and the average wheel diameter for each make with at least 20 trim listings (4 makes have fewer and are left out). The number in brackets is how many of that make's listings use the size.

Largest and smallest tires
Ranked by nominal overall diameter, the height of the tire as the size code gives it. Real tires vary a little by brand and wear.
| Rank | Size | Overall diameter | Example vehicle |
|---|---|---|---|
| Largest | 37x12.50R17 | 37.0 in | 2027 Ford F-150 Raptor |
| Smallest | 195/50R16 | 23.7 in | 2025 Mazda MX-5 Miata Sport |
Methodology
Source. Tire sizes come from documents the carmakers publish themselves, such as order guides and specification sheets. We show a size for a trim only after we have verified it in one of those documents, and each vehicle page links to its source. Nothing here is estimated or taken from a sales database.
What is counted. The unit is the trim listing: one make, model, model year, trim and size, counted once. A trim that offers two wheel sizes is two listings, and a staggered trim is one listing for its front size and one for its rear size. The data covers 27 makes, 203 models and 903 model-year pages, 2002 to 2027.
What is left out. Trims we could not verify against a carmaker document are excluded, and so is any size we cannot read as a standard tire size. We do not fill gaps by guessing, so some vehicles are missing, and how much of each make is covered differs.
Not sales-weighted. Every trim counts once regardless of how many were sold or built. A rare trim weighs the same as a best seller, so these shares describe the sizes carmakers offer, not the sizes on the road.
Definitions. Staggered share is the share of trims with at least one front and rear size that differ. Averages are plain means over listings. Overall diameter is nominal, from the size code. Tables leave out makes under 20 listings and model years under 100 where too little data would make a figure unreliable.
Freshness. Data as of October 2026. The figures are recalculated each time the site is built, so they change as we verify more vehicles.
Download the data
The same data as the page, free to download. The trim listings file has one row per trim listing (6,137 rows) with make, model, year, trim, tire size, wheel and overall diameter, and the carmaker source. The summary file holds the headline tables: the 20 most common sizes, the wheel diameter shares and the average by model year (the listings column is n for the by-year rows).
