Mud Tires

Mud Tire Specifications Dataset: 6 Tires in 4 Sizes, One Source, Matched Rows

Every row of the specification database as one flat table: 24 tire-size combinations, 6 mud-terrains in 4 common sizes, with measured diameter, weight, tread depth and the listed maximum load at its stated pressure. All figures come from a single source read on the same day, so a gap between two rows is a gap between two tires, not between two databases.

25.1 lb

separates the heaviest listed row (Nitto Trail Grappler M/T 37×12.50R17, 87.3 lb) from the lightest (Milestar Patagonia M/T-02 LT285/70R17, 62.2 lb). Weight is unsprung and rotating; it is the specification people underestimate most.

How we built this

Every figure on this page comes from one source, the tiresize.com model specification pages, read on the same day. That is deliberate. Specification databases disagree with each other, and a table that takes one tire’s weight from one retailer and another tire’s from a different one produces differences that are really differences between sources. One source, applied consistently, means a gap between two rows is a gap between two tires.The trade-off is that a single source can be wrong. Where we have found this one contradicting itself, it is recorded below under “where the source is inconsistent”. Where other pages on this site quote a figure from a different source, that page names its source. Diameters are listed measurements, not the nominal size on the sidewall.Load is shown as the listed maximum at its stated pressure, then the load index and load range. A maximum load is only mean

Where the source is inconsistent

Two entries on the source contradict themselves, and we record them rather than quietly pick one.Nitto Trail Grappler M/T, LT285/70R17: the source lists the Load Range C and Load Range E versions at an identical 66.4 lb and an identical 18.9/32″. The Falken’s C and E versions in the same size differ by 2 lb and 2/32″, so two load ranges sharing both figures exactly suggests one row was copied from the other. We show the E, which matches Nitto’s own weight figure.Toyo Open Country M/T, LT285/70R17: the source lists the Load Range C at 65 lb and the Load Range E at 64 lb, the lighter-duty tire heavier than the heavier-duty one. We show the E and flag the figure as uncertain. For more cases of databases propagating errors, see what the spec sheets get wrong.

What is not in this table

Noise, snow and wet performance are not in these tables because no comparable figure exists for them. Only Nitto publishes a noise number, and it is measured against Nitto’s own Mud Grappler. None of the six carries three-peak mountain snowflake certification. No independent test covering all six was found.Manufacturer claims, sidewall construction and warranty terms are on each model page, where they can be attributed to the company that made them. They are not specifications of the same kind, and mixing them into a size table would make them look more comparable than they are.
