universal ED & erzberg ED “Extension Felds” With Wear Bars
Made in 8.2mm, 10mm, and 12mm
TitanGrip® & ThickThin® technology
Pewag snow chains – now lighter and with longer life span
Snow chains marked with the TitanGrip® trademark are made from a special high-grade alloy steel. The combination of tita- nium and Boron steel in conjunction with a sophisticated heat treatment process provides maximum wear resistance.
A chain is only as strong as its weakest link.
But why must every chain link have the same shape?
Can we build better chains by combining different types of chain links?
Pewag found the answer by consistently working on a new technology to radically improve chains. The result of this research is the ThickThin® technology. For the first time in the history of chain manufacturing different chain links (different in shape, length and thickness) can be assembled in one chain. For this reason Pewag can manufacture the best combination for the various areas of use.
What is your advantage?
Reduced weight, considerably longer life span and optimum traction performance.
Tractor Tire Sizing
universal ED, erzberg ED, OTR & Tractor Sizing Information
The Goodyear OTR tires shown to the left are a graphic example of this variation in physical size – Both are cataloged as 20.5R25 tires – yet there is a 17% difference in the physical size of the tires when fitting a tire chain such as the pewag universal & erzberg chains. There is a 5.7” difference in the diameter of the 2 tires which directly effects the length of the chain needed to connect around the tire by 17.9”.
How is this calculated?
Diameters are translated into circumference by multiplying:
diameter x 3.1416 x width = tread area to be covered by the tire chain. In
the example to the left, this calculation yields results of 3815 vs. 4549 sq inches; a 17% variation.
Pewag universal & erzberg chains are designed to fit up to L3 tires – (that have NOT been capped). For capped L4 tires and L5 tires – Pewag makes “Extension Felds “ which can easily be added to the chains to increase the length of the chain for these type tires. The use of extension felds ensures the best possible fit on the larger OTR tires and should be anticipated when ordering any tire chains for use on OTR tires.
Pewag will custom build chains for ANY tire size. Our experienced chain builders are standing by to fulfill your request.
