Crate 21&55 Tire Help?

[CrateMafia]

I was wondering what is the best way to groove and sipe these tires. Going to run these tires for the first time next month and was wanting to get a head start on what I need to do to them. Thanks for any help that I may recieve.

i assume you are talking about the WRS2 D55s. we are required to run hoosier wrs2's and we like to sipe them in a checkerboard pattern about an 1/8" deep make sure they sipes have just room in between them. we like to sick to about 1/4" to 3/8" so the tire heats and cools as evenly as possible.

it also depends on what the track conditions are "dry or tacky" the direction you groove your tires can promote side/forward bite depending.
