23° Tread Bar Advantage

For years, farm tires were stuck in a rut. Then in [1950], Firestone introduced the innovative 23° tread design, offering a solid solution to poor traction in the field. Today’s 23° technology offers a longer, smoother ride with more even tread wear. With increased traction, the 23° bar helps to maximize horsepower, making it possible to save both time and fuel in the field.






The 23° Tread Bar Difference:


  • • More tread in the working tire footprint 
  • • Lower tread angle delivers better grip and 15% better bar-to-ground contact than 45-degree tread bars 
  • • More even tread wear means a longer lasting, smoother ride

Same Field. Same Load. No Comparison.

We put the Firestone Radial All Traction 23° R-1 up against the Michelin® Agribib® R-1W in a side-by-side, tread-to-tread comparison, and the finish wasn’t even close.


Nearly 50 observers attended the Firestone vs. Michelin traction demonstration. Here’s what they had to say.

Dean Manthe

DeForest, WI, Manthe Grain Farms

“We’ve used Firestone tires on our farm for 25 years and always liked the traction. You would think Michelin’s deeper bar wouldn’t slip as much. I thought there was a difference before – this demonstration reassured me.”

Doug Yelk

Marshall, WI, Yelk Farms, LLP

“It was a fair and balanced demonstration – I was picked to ride in one of the tractors to monitor the RPM. I was surprised at the difference in the outcome. The 37 feet is a significant difference in time and fuel.”

Mike Earhart

Cedar Rapids, IA, GCR Tire*

“I was surprised that the deeper bar on the Michelin didn’t offset Firestone’s R-1 bar with the 23° angle. I now have an answer for those who question the “deeper bar” difference. I don’t know how anyone could have made the demonstration more fair.”

Tom Sandbothe

Griswold, IA, Sandbothe Firestone*

“I sell Michelin, Titan® and Goodyear® tires as well as Firestone. This demonstration convinced me that the 23° bar makes a difference. Michelin tested their tires in wet soil conditions, but in normal soils like we saw, it doesn’t compete as well.”
