Video basically says it all. I modified my MAXXIS Trepadors with some tire grooving/Siping for improved winter performance. I think I can call this successful, but unfortunately we've had such a mild winter I have had limited opportunities to properly test or quantify the improvement.

Additionally, due to this mild winter, there has been little need for improved winter performance. So, I am not confident I can really say the juice was worth the squeeze. Regardless, it was an interesting and rewarding project!

interesting video...I always worried that the siping and grooving would throw the ballance outta wack...? looks like a great solution for tires partially worn out!

Looks great! Are they a little bit quieter?

I use balance beads, big fan. They aren't perfect, but give you a decent balance for the life of the tire, regardless of chunking. I think they are a great option for largish tires that see abuse.

You know, I cant say I could tell any difference there. The Treps were never a quiet tire by general standards, but in my opinion they are extremely quite by dedicated mud tire standards. Some of those can get quite terrible.

With the capability of computers to do modeling and simulation for tire design, I wouldn't feel confident that I could improve upon what was already designed and tested by the manufacturer.

This is true, thats the primary reason I basically copied the OEM pattern with slight augmentation. I cannot argue that I improved the design as a mud tire, only that I gained some small performance in the snow, which the tire designers were not trying to design towards in the first place. It's still an excellent tire that I recommend.

Oh, I went down this rabbit hole a while back. Seems like there's a whole lot of conflicting info on the efficacy of siping. Most manufacturers and tire dealerships don't agree with it while some guys swear by it. But shaping/shaving tires for a specific purpose absolutely has its place. Interesting to see how easy it is to re-groove a tire and make it look nice and factory though.

I agree, I think generally you should just buy the tire for its intended use, siping will never make up for factory design or compound, but in this case I wanted the steer the performance a tiny bit towards the snow, and I think it was moderately successful.
