Crop Max R1 Overview


The Crop Max R1 is a rear farm tractor tire specially designed for long lasting field performance and longer tire life. It features 45-degree tread lugs which help it maintain traction on loose surfaces like mud, sand, and soft soil. The less you worry about slippage, the better you can perform at your job. Because of the improved traction, the Crop Max R1 doesn™t consume as much oil making it a fuel-efficient tire. The long tread footprint minimizes impact on soil while increasing crop yield. Helping it last longer is the wide lug nose and the special compound. And because it™s self-cleaning, no debris gets stuck in between the lugs allowing you to seamlessly switch from one task to another. The dual angled lugs ensure you enjoy a comfortable ride. This makes you feel less worn out even after a long day of hard work in the field.

Features & Benefits

  • Ideal for trailers, spreaders, balers, ploughs and drills
  • Optimal tread design and rounded shoulders provide soft ground contact while creating minimal damage on the soil
  • Low rolling resistance means you get to save on gas

Great tractor tire for the money matches the other one perfectly.
I use these tires on a 4 wheel drive articulated tractor of my own design. It is built mostly for show and these tires look and preform great, lots of positive comments. Thanks for your prompt and outstanding service. Roger Reichenbach
I had these tires on for 1hour and put a twig through the side wall and the twig was tiny. Not real happy
