Need some tire help

[Ralphy]

We do cut the block into quarters but have not tried the 3 times around sipes. How deep should the sipe be?

May I ask where you run?

[Ralphy]

We run limited and super late races in Md, Pa, Va, and Nc. Mostly limited motor races.

if you talk to Hoosier they'll tell you a sipe should only be 1/32" deep. enough to get the initial fire out of the tire and the rest is up to the driver. We always run a foamy and when a caution comes out KEEP IT HOT!!

Thanks centralpa43. We will try that this weekend.

1325's are unique in so many ways. Just when you think you have the tire cut up as much as you possibly can, cut some more. Do you remember the football cleats, the ones that were little circles, and they were very small? That's about how you need that 1325 to look. In my opinion here's the trick to a 1325, sipe deep but don't groove deep. Only groove about half as deep as you normally do. When you do this it leaves a mass of rubber under all of your very small surface blocks to hold the heat build up. With that mass of rubber holding the heat it dramatically helps the tire hold that heat under a caution and not allow it to seal up. That's all I'm going to share on that but if you need some more help you can call 618-304-2674
