Tire siping

Post by Twebba »

A while back (last summer, before the hacks to the forum), I posted a thread about whether or not I should sipe my tires. You see, I live in the mountains and my road is 2 miles of uphill, snow-packed ice until mid-April or May. (Probably June this year :lol: )

The general consensus was not to do it for a variety of reasons, so I heeded the warnings and did not get them siped.

:arrow: Fast forward to a more recent time… :arrow: :arrow: :arrow:

I’d been using my Pinz as a daily driver for a while. The first few times after the road froze over was absolutely terrifying. I felt like a bobsled without a track. (For those of you who have never experienced a 270-degree slide in a Pinz, let me tell ya - it’s a very strange feeling when you’re sitting on top of the front tires. :shock: )
We’ve had other vehicles siped, so I said, “Screw it, I’m getting it done!” and so I did.

Since then, I’ve been driving around through all the snow and ice and we’ve received in Colorado this year and haven’t had any more close-calls, even while swerving to avoid a startled fawn. 8) (-Probably just jinxed myself).
Now I’m not saying that the siping has turned the Pinz into a performance ice-monster, but it has CERTAINLY helped a lot more than I ever expected.

- Just wanted to follow up and share my experience thus far. :roll:

And BTW… I’ve been told by the tire manager that any problems experienced when I’m out wheelin’ next summer (like ‘chunking’ that a few people warned about) will be covered under warranty – although they don’t expect that to happen.

(flame away) :twisted:

I"ve had Discount Tires sipe the Michelins I had on a Cherokee years ago; couldn't really tell the difference at that time. However Discount has been a really fair and honest dealer that I have used, I would trust them if they guaranteed the siping. Living up in the mountains where I do I had several tire stores tell me that they would not honor a mileage warrantee on my car tires, but Discount will.

So, who did the siping on your tires?

I'm Running BF Goodrich Radial Mud Terrain's
255 85 R16

I wasn't able to tell a huge difference in the cars/SUV's we've had siped, but it was pretty evident in the Pinz that it's helping hold the road better.

Discount Tire sold me the tires and did the after-market siping. I've had the same experience with them; they've always been very decent and fair to work with. I trust 'em.

Siping...

Taking a look at the mainstream winter tires available for passenger cars, (such as the blizzak) its evident that on-ice tire performance has a very distinct relationship with edge effect. in other words, the more tire block edges that you have contacting the ice, the better your grip is going to be under icy conditions.

in short, I would be surprised if you did not notice a positive difference considering the conditions in denver the last month or so. (and yes, I've been in a 180degree broadside slide in a pinz. scary as poop) :shock:

where the concern comes in is during the summer when your off 4wheeling with your buds in moab. I've come back from there with pinky sized chunks missing from my unmodified 285 MTR's. hot tires and loads of grip = trashed tread blocks.

so the bottom line is in how you use the truck. for me it wouldn't make any sense. (because the truck is used mainly in the summer) but for you it was probably the best choice.

happy pinzing!

How deep does aftermarket siping go?

Doug, That was my main concern as well, because I do a fair amount of trails in the summer. Nothing too extreme, but enough rocks that I have my doubts as to how they'll hold up. I guess time will tell.
Since I use it a lot in the winter, I figured I'd error on the side of safety.

The siping didn't go as deep as I would have expected. Maybe 1/4 inch or so.
Seeing that the tread's are a bit over 1/2 inch deep, I'll probably be out of siped tire before too long.
When I asked about it, Discount also said they'd redo it for free when I get to that point.
I thought that was pretty decent of them.
