Why can't tires be siped a second time after they wear down a bit...?
Thanks.

Siping is a waste of $$ and time in the first place.:pee:
Some of us like siping and enjoy the benefit of better traction and extended tire life.

Siping is a waste of $$ and time in the first place.
you must never have siped a set of mud tires before.
Part of the reason as I was told you can't get them siped a 2nd time is all the sand and pebbles embedded in the sipes or tread dull the blades quickly hence tire shops won't do it.
You could always sipe them yourself, just make sure to stay out of the tire carcass.
And siped tires do wear quicker under heavy loads. Can't argue whether they run cooler under load but the road trip to AK this yr with a 4000 lb camper on siped Toyos wore those rear tires about 4x quicker than empty and at least twice as fast as non siped.
Still would reccomend siping of solid block tread tires for wet and snowy conditions. It's like havin a dedicated snow tire.

Bsck on topic I believe you cant sipe a second time for the same reason you dont cut rotors past a certain thickness. You need X amount 9f base material to work with.

Yep...pink for sure. Get a better traction tire suited for your needs. Cutting the tread for traction is basically shortening the actual tire life by modifying the original tread. Tire shops have been selling it for years. Nothing but an upsell. Why dont manufactures sipe their own? Because it is a waste of money. However, if you believe in it then do your thing.

Hit the nail on the head.

Back to the topic though, siping a second time can overlay old sipes with new ones and create areas that are too thin for safety and drastically increase the chances of the tread pealing off. They cannot ensure that all the old siping is gone and for liability reasons will not do it a second time.

Siping works very well, manufacturers have been doing it for years and know the value. Look at a set of new tires, you see all the little squiggles through the blocks of tread? That is siping. Look at studless snow tires, there is usually extensive siping. They significantly improve traction in most instances, I certainly disagree that it is a waste of money. Most tires have siping to some extent when new but they wear down turning the tire into a solid block tread. My Nitto Terra Grapplers were skates in the snow once they wore down a bit, after siping they gripped much better an so far I have not had any issues with increased wear. I would not do it to a tire I was going to be climbing with in heavy or sharp rock, that is where full block treads are useful and where siping is not necessary for grip anyway.

Great reply, thanks.

Siping increases traction in in wet and snowy conditions only temporarily. Once half the sniping is worn, the tires have worse wet then non-sniped.
In the extensive testing Consumer reports did, they recommended not added sniping, over what most tires already come with.

You would think all these big tires manufacturers would send the tires out already siped if it truly was a benefit to the life and traction of the tire... :dunno:

Added Siping actually decreases your tire longevity substantially and decrease traction in dry conditions.

Do you have a link to this information?

Why would they. :dunno: I will guarantee they would rather have you buy another set rather than get an extra 5-10K miles out of them. :twocents:

Love them..
If your wearing out tires you might want to slow the hell down! Just sayin

Basically the only tires that aren't adequately siped from the factory are mud tires. That's never an issue except for the guys that insist on running mud tires on trucks that never see anything more than pavement or a gravel road.
Mud tires look cool but suck in rain,snow or ice. Guys would rather have cool looking tires than a tire that actually fits their need 99.9% of the time,so they have them siped to try and make up for the mud tires deficiency on pavement.

You don't think the company selling the tires would think the same way? All I have is experience to go off of, and that is siping for offload tires does more harm than good.

Siping a 4x4 tire is trying to reduce the excessive wear from using an off road tire on the road... A misapplication of use. IMO the only tire i have seen really helped from siping is the Interco TSL Super Swamper. the main reason for it is its design. If that tire is over inflated it mostly runs on the two ribs that run down the center. Siping those two ribs decreases the wear on those two ribs while pounding pavement.
If you want the maximum bang for your buck I would recommend an all season or all terrain tire on your 4x4 that you commute in. A winch and good set of link chains, will save you off road and your pocket book over the long term. If you have a dedicated hunting/ off road right then buy what ever aggressive tire floats your boat.

I guess I'm confused by your first sentence? :dunno: If the tire companies sent out siped tires and people used them for the wrong applications, then I highly doubtly think they'd be in business long with all the returned chunked out tires. Also, if you read my previous post, you will see that I also mentioned using siping for off road tires isn't my recommendation. However, I center sipe all mud tires that I use in the winters, and have had great luck with better traction of icy roads.
