Siping OEM AT Tires?

[DocStizzle]

I am set to take delivery of a FS Cyberbeast this friday. This is the first new vehicle I've ever purchased and I'm coming off driving a 2013 Nissan leaf the past 6.5 yrs so this is quite the upgrade. I live in the mountains of Montana @5500 ft elevation and drive on snow and ice covered roads for at least ~4 mos out the year. I have traditionally run a studless snow tire (Nokian Hakkapeliitta are my favorite) From about Nov 1st - May 1st on my vehicles. My Cyberbeast is coming with cyber wheels & AT tires. My long term plan is to run a summer setup and a winter setup on their own set of wheels. I like the idea of going for better efficiency in the summer by running core + all season tires, and then going for more safety and road grip by running a dedicated winter setup in the winter. What are peoples thoughts on siping the AT tires for this first winter? It seems that there aren't a ton of winter tire options for CT and at this point they're probably mostly sold out? I also would rather run a more efficient tire in the summer so trying to improve the AT for winter driving seems like a reasonable trade-off (as opposed to selling them on eBay, or storing them for a future use case.)

Keep the AT wheels for summer.
Buy some dedicated winter meats asap. Or the BFG K03.

The stock AT tires are not very good in snow and terrible on ice. They have very little tread depth.

I drive our CT to the winter wonderland of Vermont every weekend and have enough experience to say winter tires are a necessity if you’re in a place with true winter weather.

Have not had a chance to do a ton of snow driving but the heavy rain driving it did seem like the AT tires hydroplaned a bit more than I was comfortable with. Fortunately we don’t get a ton of rain so I am hoping to run the stock AT until they need replaced and will switch to something like the BFG K03 year round. I don’t want to mess with a summer set of wheels mostly because I don’t want to find a place for them and the extra set for the X. There are a number of good threads on here about tires and a good number of people that have reported what they are using, I’m sure you can find some of those threads that will help.

Would you be willing to take a tread depth measurement when you take delivery or shortly after that? I recently picked up the spare tire kit and that tire had 13/32nds new. I’m curious if the new rides with AT have the same.

Thanks the replies. I was hoping someone had siped their ATs, but it appears not. I'll run the experiment. I talked to my tire shop and they thought it was worth a shot. If they suck he said there aren't many winter options in the 285/65/20 but there are plenty in the 275/65/20 and you can put those on the same wheels?? I'm guessing that's what you all have done that are talking about blizzak and Nokians. I'll report back on the siping and winter driving, at least in my neck of the woods.

Does the tire shop guarantee that their siping won't cause chunking of the tread? I would be quite concerned about that, especially on a Cyberbeast. Some tires are more susceptible than others and, of course, more power/torque/weight is an additional risk factor.

I used to be a big fan of siping, now I buy tires that suit my purpose from the factory.

Update on this... I ended up stopping at a tire shop and asking about siping the AT tires and the guy at Les Schwab east of Spokane, WA said the trouble is that the AT tire is s "summer" rubber compound and basically freezes at temps below freezing. Whereas a dedicated winter tire has a different rubber compound that is made to stay soft at freezing temps and grip the road better. So I ended up putting the 275/65/20 Nokian LTs after all.

Also to answer the tread depth question my OEM AT tires measured at about 10/32nds tread depth.
