how do u plan on doing it, i know guys that have put there trucks in 4wd and went to a parking lot and turned there wheel to lock and did like 100 circles then when they went to pull the put rears on front and fronts on rear

 

i have never even heard of this before. what is siping and what does it gain you?

 

it is when u chop the tire to create a leading edge on the thread to get alot more of a bit on the dirt, the front of the thread of the tire will be higher then the rear of the thread in front of it, u can also do it with a tire grinder, its a tool that goes on a angle grinder and u can grind away rubber for the tire, the tool looks like a cheese grader

 

I hope you haven't done it, most places will call that a cut tire. While it is DOT legal, it falls in the category of cut tires.

"Siping" - http://en.wikipedia.org/wiki/Siping

It's just putting small cuts across the tread blocks to create more leading edges than what the tire originally had.

 

I can run cut tires in prostock class so I'll be alright

 

get a set of 35in. sts's thats what jeff pelletier and brian bouchard are running on their dmax's

 

Dirt track late models sipe tires but I cant tell you why. I've seen it done, you need to know what your doin or you can ruin a set of tires.

 

siping can add a lot of traction to a tire...if you dont think so then look at the tires some pro-stock guys run on the their trucks. some dont look like much more than an A/T road tire, but they have a ton of siping from the factory and they bite very well.

a snow/ice tire has a ton of siping for traction but they dont make them in the right sizes to run on most pullers.

 

I know the sts's are probably the best, but no funding for new tirs right now

 

trust me i hear ya there buddy. i got the tires just not a lot of hp/tq to go with it now lol

 

siping tires is a dirt racin trick... not sure how much it will help with pulling in racing you get more side and forward bite when a track slicks up and can keep your tires cooler by releasing heat not a factor when pulling.... not sure its what ud want to do to a set of tires........

 

Alot of guys say it helps alot on a hard track, I guess I'll see

 

Siping is more about the traction of a tire than heat. There are waaaayyyy more factors that contribute directly to the temperature of a tire before siping. Depending on how deep the sipes are, and how many you make, siping can make the tread of the tire more flexible under load. This allows the tire tread to "open" giving you many tiny cutting/biting edges on the tread itself, in addition to the factory grooves between lugs, making more grip. If you have the time and wrist power, I don't see where this would hurt.

 

All done, I'll see how they work, it was kind of a ptas, but it didn't cost anything

 

Are both classes pulling this Saturday? Or is street this Saturday, and pro next Saturday?

Thanks

Thanks

hope they are pulling both this sat, if not I won't be able to make it the next sat. because of other comitments made earlier, the fair website says this sat. for prostock, but MSTTPA schedule says different

 

I want to see that thing run too. I will probably be there too!! How is Jeff doing this year?

 

Ya, I am confused by that too. I can't make it this Saturday.

 

street is this saturday and pro stock is next saturday. jeff is first in points and hasn't lost yet this year as far as i know

 

How many trucks are running in pro with all the rules stuff you fought for last year Chad? Is it still a Jeff and Malcolm show, or?

 

Jeff Brian Bruce and Carl are the main four and malcom has pulled his 06 cummins once in pro stock

 

I have worked on race tires since 1991, go-karts, IMCA Mods, and Dirt Late Models. Siping the tires around the tire open under side bite, across the tread for forward bite. The biggest advantage of siping is releasing heat in a long feature, it cools the tire. For short races using siped tires won't let the tire heat up and doesn't start "working" until the end of the race, this is a bad thing. I would say the best thing to do is make a stand to spin grind the tire. Use a BIG grinder with a 60 grit flap wheel to square up the blocks. Tread depth doesn't win races, square corners do. You can have a crap set of tires, but if they have square edges they will bite. PM me if you need some chemical advice on how to make a tire bite.

 

Or doing a burn out would do the same really

 

So how did it go Chad?

 

8 trucks last night. The didn't let one pull because it didn't have an air shutoff. Malcolm pulled his 96 dodge, his 02 dodge is it, and his Duramax. Then there were two other Cummins guys from Southern Maine. Then there was Carl, Bruce, and Jeff. Jeff went 326 in his test pull, declined it and pulled like 330 something the second time around. Everyone else was at 314-315 or so except for Bruce who went a whopping 77 something.

 

The red cummins with the 8" single stack was my buddies, wish I could have made it, we'll be at windsor

 

When is Windsor?

 

A burn out rounds the corners of your biting edges and when done at a low psi. it actually burns off the the biting edge all together. If it is one thing I know, it is tires and how they work and why!!!

 

Sounds like good advice from this guy.

I hand siped my old toyo MT's, at roughly 520 cuts by hand per tire ( with a box cutter OLFA knife ) it wasn't easy, but I ran them all winter and they did pretty well on some nasty roads.

When I drove up the driveway on a layer of fresh snow you could look at the tracks and see where each cut had provided a biting edge. I didn't cut all the way to the edge of the tread block because I felt it would leave the tread stronger and less prone to chunking. It was my first attempt and I was pleased with the results, for the street anyways.

I've only pulled 2x, and both times the track was muddy, so the tires wouldn't have heated up no matter what, but from what I've seen your tracks down there are firm and would allow some heat, like ^^ he says.

I have access to a heated tool now that I'm going to take to my M-55's for the winter, should be easier going.
