Anyone have their tires siped? I have nitto 450's from discount and they're always trying to push the siping for $10/tire. From what I read its like make them a winter tire. Supposed to increase braking performance and grip. Any advice would be great.

 

its only for winter tires. it makes little cuts in the tires to grip into the snow.

i cant imagine it being any good for regular asphalt.

 

If you check out discount or les schwab's websites, they claim it will help any tire.

 

their statements and data are clearly describing winter use. if you want to believe they work great for summer tires, go ahead, pay the $10/tire.

But it is still only for winter use/purpose; siping is only necessary for snow traction. For dry pavement, especially in the summer heat, it won't help and will likely wear out the tire more quickly due to chunking and extra heat buildup.

I've got this awesome bridge you can get for cheap...

 

i call BS on the line "its too expensive for manufacturers to do this" yet every small shop will do it for $10 / tire. why would a tire manufacturer NOT do anything to further benefit their tires? its not like they dont have the technology to do it on a manufactured tire of their own. just look at the tread of a bridgestone blizzak, their specific winter tire.



so yeah, it helps to sipe a non winter tire for better winter performance. but theres otherwise no reason on a non winter tire. if siping helped a high performance summer tire, at the cost of $180 per tire, theyre saying its just too expensive to do? right....

 

I had mine siped. They are much quieter and grip better. They are also wearing quite well. I am satisfied with the improvement. YMMV

 

No wonmder I don't know what you guys are talking about, I am from So Cal.

 

I wouldnt get it done for dry weather...smaller tread pads = more flex....your car should feel less stable when pushed to the limit when cornering...not to mention a smaller contact patch.

 

I could maybe see "more flex". But the contact patch is virtually the same and since I don't autoX, I don't push my car to the limits of cornering. The benefits to me are a significantly quieter ride (so much so that we also siped my wife's minivan). I have not found any objective test data on tread life, responsiveness and the like.

 

I am curious what post-manufacturing siping looks like. Any one have a pic? Sounds VERY cheap for the amount of labor involved.

 

You can barely see the sipes. It is like someone used a razor to make them.

Here's the company that makes the machines. It has their propaganda in it.
