How do you read the Earth-Pro R-1 size?
Take 11.2-24 as an example. It is 284 mm (11.2 in) wide on a 24 in (610 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.
Who does the Earth-Pro R-1 suit?
Choose it for general farm work on soil that is not constantly wet: tillage, hauling and mixed use. The rim range, 24 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 Earth-Pro R-1?
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.
How does the Earth-Pro R-1 compare with similar tires?
