How do you read the Farm Specialist R-1 size?

Take 18.4-26 as an example. It is 467 mm (18.4 in) wide on a 26 in (660 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 does Carlstar say about the Farm Specialist R-1?

Carlstar describes the Farm Specialist R-1 as a tire for compact utility tractors, with overlapping center lugs for a smoother ride and a heavy-duty sidewall for puncture resistance. Its product page lists tubeless 6-ply construction and uses for balers, feed mixers, seeders, spreaders and wagons, with tread depths from 22/32 to 41/32 in across the sizes it shows. The sizes on that page are small (6-12 to 9.5-24). Our listing covers larger rears, 11.2-28 to 18.4-38, so the exact ply, load and tread depth for your size comes from your quote, not from that page.

Who does the Farm Specialist R-1 suit?

Choose it for general farm work on soil that is not constantly wet: tillage, hauling and mixed use. The rim range, 26 to 38 inches, runs from utility tractors up to row-crop machines. It is a sound pick for moderate yearly hours.

What are the limits of the Farm Specialist 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 Farm Specialist R-1 compare with similar tires?
