I'm doing a whole set, so every corner.

there's a couple things I've been told about siping. Across=grip Around=speed, and if there are too many sipes it can cause a tire to chunk. If you google tire siping you can find some good stuff

I found some good general info by Googling. Just wondered if there was anything specific I could do for the A40.

I siped a set last night. Ended up doing circumference around each tread for the fronts and across cuts (one in the middle of each block) for the back. I think I may have cut too deep. We'll see of they chunk out tonight.

thx for the replies.

They didn't chunk anywhere and I had siped them almost all the way down to the depth of the tread blocks.

Track was very slick. I don't know if it helped or not...

a needler would help on a super slick track, but a lot of places think they are made of gold
