Samson Farm Rear R-1S Tractor Tire
Put more of your tractor's power to the ground with the Samson Farm Rear R-1S. The directional bar-lug tread bites in loam, clay, and mixed soil, then sheds mud to maintain traction between passes. A robust casing supports heavy implements while the tread geometry balances grip with soil protection. For field prep, pasture mowing, and short road runs, the R-1S delivers dependable performance at a strong value, available in sizes and ply or load ratings to fit your equipment.
Features and Benefits
The Samson Farm Rear R-1S is built for everyday farm work. Its directional bar-lug pattern transfers torque efficiently and self-cleans in damp ground to keep bite consistent. A cut and chip resistant compound and sturdy casing stand up to stubble, debris, and gravel lanes, while the lug-to-void balance helps limit slip and compaction. Optimized lug angles add stability on mild slopes and during headland turns, making the R-1S a confident choice for mixed field duty and short transport.
Sizes, Fitment, and Specs
Match rim diameter, overall size, and load or ply rating to your tractor's requirements before you buy. Many sizes are offered in tube-type or tubeless versions, so select what your wheel and manual specify. Verify load index, inflation pressure, and speed symbol against your heaviest implements and typical transport speeds, and account for duals or ballast if used. Share your current size, rim width, and application, for example 18.4-34, to confirm an exact fit.
How to confirm fitment
Read the size on your current tire sidewall and confirm it matches your operator's manual. Note tube-type or tubeless, recommended rim width, and the required load or ply rating for your implements. If you've added a loader, ballast, or duals, recalculate axle loads and inflation, and make sure the speed symbol fits your road speeds. When in doubt, provide your equipment model, current size, rim width, and duties for a quick fitment check before ordering.
Field Performance
In tilled soil and pasture, the Samson R-1S uses its bar-lug design to cut slippage and pull implements with confidence. Lug spacing promotes self-cleaning in damp conditions so grip stays consistent across the field. The footprint aims to limit compaction while keeping straight-line stability and controlled headland turns. On hard surfaces during short transport, the casing and lug support help maintain steady handling and predictable wear.
Price, Value, and Warranty
Price depends on size, rim diameter, and load or ply rating, with larger and higher capacity options costing more. Tube-type vs. tubeless, freight, and regional promotions can also affect your delivered total. For best value, match load rating and inflation to your heaviest work to protect the casing and extend tread life. Review the manufacturer's warranty for your exact size and application, and request documentation if you need it before purchase.
R-1S vs R-1 and R-2: Which Tread Do You Need?
R-1S is a versatile agricultural drive tire with bar-lug traction for typical farm soils and mixed tasks. Standard R-1 patterns perform well in loam and drier fields, while R-1W variants add deeper tread for softer or wetter ground. R-2 designs use very deep lugs for rice, cane, and standing water where maximum penetration is needed. If your work spans field prep, pasture, and short transport, R-1S is often the right balance of traction, longevity, and cost.
Installation, Ballast, and Maintenance Tips
Have the Samson Farm Rear R-1S mounted by a qualified agricultural tire technician, especially for tube-type assemblies. Set cold inflation to match load and speed per the spec sheet and your operator's manual, then recheck as temperatures change. If you need ballast, calculate target weights and choose liquid or wheel weights accordingly, and use corrosion protection with liquid fills. Avoid extended road speeds beyond the tire rating, rotate or swap positions to even out wear, and store equipment clean and out of direct sun in the off season.
