When comparing prices, you must look beyond the surface and evaluate the Ply Rating (PR), which determines the load capacity and durability; typically, a 4PR or 6PR is standard for small tillers. Additionally, check the tread pattern depth and design (such as herringbone or lug patterns) as deeper treads provide better traction in muddy soil but may increase the cost. Ensure the rubber content percentage is specified, as higher natural rubber content (typically above 40%) ensures better elasticity and resistance to cracking compared to cheaper synthetic alternatives.
