About three years ago, RUD USA imported the Olympia Sprints tire chains. For the mid-sized truck, we absolutely loved that chain. It was more aggressive than the Grip 4×4 – an already great chain – but it fit the market for the heavier mid sized trucks such as the RAM 2500 and above and the F250 / F350 trucks. What was attractive was the industrial strength of the side components which could withstand extra torque. Last season, we sold the remaining of the 131 models and we have come very close to selling the last of the 136 models. They never did deliver the 140 model for the 35 inch tires; nevertheless, we knew the demand was there. These Olympia Sprints chains had a link size of 6mm.
This year, RUD USA is trying something new. They have an overabundance of 7mm cross chains and using the team that manufactures their industrial chains in Iowa, that team is assembling the newest versions of the Olympia Sprints. You will know if it is this chain if it has MFG in the name. Starting today we are selling the Olympia Sprints 131 MFG. At the same time we can also offer the Olympia Sprints 140 MFG. When we deplete the 136s then we will start assembling those too. The 132s will follow shortly afterwards. We have been spending our summer time going over prototypes for this chain with the intention of getting it right. Today, we tested the new 131 MFG on several tires and have confirmed a proper fit on the following sizes.
I am excited about this chain. It is very strong and very aggressive. I also had a nice experience in learning about the hardness of the metal. If you take bolt cutters and cut through the side chains, it is not overly difficult to cut through the metal. However, when you try to cut the cross chains, you will find the hardness of the metal extremely different. I had to exert a lot of energy to get it to cut through the chain. In order to preserve my bolt cutters – not to mention one of the fragments shooting through the window of my truck like a bullet, I stopped cutting them. That metal is very hard and very dense.
Here are some pictures of this new chain including some comparisons. First is a comparison of the Grip 4×4 link size to the original OS 131.
This next image is a comparison of the link size and chain layout of the older and smaller OS 131 compared to the newer and thicker OS 131 MFG.
Now, we have the chain installed on a Ram 3500 dually.
Due to the thicker chain, the price is a $30 – $40 dollars more.
What I also like, is that since they are being assembled in Iowa, we get to claim these chains as MADE IN USA.
