Siping / Regrooving Tool

[yooperdave]

What is everyone using to put sipes into their R4 tires? Do you need heat in the tip to burn the rubber?

Part 2: How big of grooves are recommended? How deep? U shaped or V shaped?

Pictures of the finished product is appreciated!

TIA

@dnw64 may loan you his if you ask nice !

But, yes, you need heat to make it work, besides a sharp blade ...

Yes, I have a groover and am willing to lend it to TBN users for the cost of shipping. Send me your info if interested.

Yes, heat is used... better to do it in the summer when tires are warm!!! I used #4 which I think are 1/4" wide and deep...

Link below is what I bought, I just redid mine not so long ago.

Boy has the prices gone up, this is NOT where I bought mine but it's the closest thing I could find. (this is just what mine looks like):

I used an Ideal Tire Groover with the #4 blade. It cuts a "U" shaped groove, and the depth is adjustable.
