How do you read the 324 FarmPRO size?

Take 6.00-16 as an example. It is 152 mm (6 in) wide on a 16 in (406 mm) rim. The dash in a bias size marks the construction, and in an inch size the first number is the width in inches and the last is the rim diameter. Our tractor tire size guide explains every number on the sidewall.

Before you order, check four things: the rim diameter matches your wheel, the load rating covers your heaviest working weight, the new tire matches the other tire on the same axle, and the size matches what the tractor maker approves.

What is new in the redesigned Alliance 324 FarmPRO?

Alliance, part of Yokohama Off-Highway Tires, redesigned the 324 FarmPRO in 2015, according to Modern Tire Dealer. It stayed a bias-ply tire. The new tread has slightly curved 45-degree lugs with a wide-nose bar and blends features from several of the maker’s earlier R-1 designs. The compound was changed to slow cut growth and resist weather. The maker positioned it as a value tire for general-duty tractors that mostly do yard chores and road travel, and said work with planters, tillage tools and sprayers calls for a radial. The article is from 2015, so ask us for current specs.

That fits our catalog: the 324 FarmPRO comes in many sizes and ply ratings, so it covers small utility tractors up to 23.1-26. If your tractor works long, fast days, look at the radial Alliance Agri Star II instead.

Who does the 324 FarmPRO suit?

Choose it for general farm work on soil that is not constantly wet: tillage, hauling and mixed use. The rim range, 16 to 38 inches, runs from compact and utility tractors up to row-crop machines. It is a sound pick for moderate yearly hours.

What are the limits of the 324 FarmPRO?

Bias casings give a shorter footprint and a firmer road ride than a radial, and R-1 lugs are shallower than R-1W, so very wet or heavy ground can slow it down. The radial vs bias guide covers the trade-off, and the R1 vs R1W guide shows when the deeper lug is worth it.
