NFR Truck tires?

I thought the Pinza are siped at factory. From the TireRack website….

Utilizing a computer-aided design, the Pinza AT's four groove tread pattern is built to provide a rugged, off-road look that retains respectable road manners. The multi-pitched pattern employs aggressive biting edges in the shoulder elements along with a higher void ratio for good loose-surface grip. Full depth siping and large zig zag circumferential grooves help increase wet weather traction and hydroplaning resistance for enhanced confidence in wet and wintry weather.

Most of the major tire manufacturers have incorporated siping grooves into their winter tread design mold patterns for many years. It's a whole different thing than distributor pre-consumer razor slicing (which the mfgs don't recommend).

Discount Tire (which is considerably larger than LS) does not recommend nor will they provide tire siping for their customers.

One study found a small but measurable improvement in traction on snow and ice, but an increase in stopping distance on wet roadways.

Consumer Reports tested Michelin Energy MXV4 Plus and a V-rated Michelin Pilot Exalto A/S, with and without siping and said the same thing, except braking on dry roadways also increased by a few feet.

Same set of priorities for the Xterra, I went with the Firestone Destination and am more than happy after maybe 3 seasons. Will replace with same. (Steve, make sure you keep the Husky sticker!)View attachment 130092

I have these on my truck Tim, and I just replaced them with the exact same tires. They are great tires, and relatively quiet compared to BFGoodrich AT.
 
All good points, however, stopping on dry pavement is least of my concerns since we get a whole lot of ice days here in winter, including black ice on the highway into Bend, and tire grip is absolutely essential in those conditions.
We've had several ice mornings since the siped tires were installed, and with no one around sped up and then locked the brakes to see the results, which was excellent tire grab.
As to the stiping itself, comes down to the technique/machine used. LS use a machine that rotates the tire while the cutter makes very thin 90 degree zig zag cuts.
Horses for courses...
 
I've had Falken Wildpeaks AT4W for about 10k miles now on my 4runner and really like them. Have not experienced much snow yet but it handles well in the rain, good braking performance.
Previous tires were Toyo AT3 Open Country, those were great too, good in snow and rain.
 
My opinion on tire siping is that the manufactures' engineers spend a lot of time designing and testing their tread designs and performance. I would think that siping would likely degrade that performance rather than enhance it.

That's my opinion, and why I won't sipe my tires.

Have heard good things about the Wildpeaks. Not a fan of Toyo, never run the AT3's ,but the AT2's were terrible IMO , expensive ,and not a very good wearing tire . As said the Cooper AT3 XLT's have been excellent so far on my truck Ram 3500 .

The Toyo AT3 lasted over 72k miles for me, could have lasted way longer too but I was itching to get new tires :) I rotate my tires religiously every 5k miles so I think that helped.
I’ve never tried Toyo AT2.

Same here every 5k on rotation . My truck is a bit rough on tires anyway ,towing a fifth wheel . The Toyo AT2's were pretty much done at 38K. I suspect SUV's are pretty decent on tires ,compared to a 1 ton truck .

Considering my F350 empty weighs 7,400 and change I think you’re right

Yes- When I got my Crosstrek 5 years ago I immediately put BFG AT KO2s on it and got over 80k miles out of the first set!

I just got a new set installed Wednesday. I was trying to wait until the KO3s were available in my size but got impatient and just went ahead with new KO2s.IMG_5706.jpeg

I’ve been really happy with the BFG ATs, had them on multiple PU trucks as well.

Never have been a fan of the BFG's , what I remember with them ,was they were the worst rock throwing tires I have ever run . It's been years since I have had a set ,possibly they have changed since then . I just remember an old blazer I had rebuilt the entire body ,and repainted running those tires on a gravel roads hunting I would cringed hearing all those rocks hitting that new paint . 😂 I got over it after several rock chips, it was just the nature of the game hunting . :)
 
the evil of sipping..lol
below are photos of the sipping on factory ice rated tires and what LS does with their machines. As to why manufacturers don't recommend it and will void the warranty (LS covers the factory warranty for all tires it sells and sipes), the more siped the tire the less miles it will last, why the Michelin Ice-X pictured below are only given a 40K warranty vs the 60K of other LT tires. More traction = more rubber lost per mile.

Oh yeah, that’s a legitimate concern! I throw gravel all over the damn place with the 35x12.5s

So Pinza's from LS now on my rig, had them perform their machine stiping on the set for extra ice traction, which is a debatable thing, as some opine it unnecessary for a snowflake rated tire. Talked to the shop manager, however, who said all the installers do it for their personal vehicle, which is a pretty telling recommendation.
Initial takeaway after driving through our first snow of the year - whole lotta grip.

@SurfnFish, having a winter on the Pinzas, how do you like them? I haven’t had mine in any snow/ice other than a brief trip to see my youngest, less than 20 miles in packed snow and ice in which I was very happy. The highway driving I have done show very good ride and noise quality for a 120/122 rated LT tire. Only 6K miles so too soon to indicate treadlife.
 
I will add this to the siping discussion. If you drive a heavy duty pickup or do a lot of towing, please don't sipe your tires unless they are almost worn out and you are trying to limp through one more winter.

Also, be careful with Tire Rack ratings. New products tend to get high ratings. If there are millions of miles and they are still rated well, that is more reliable data.

excellent, handle snow and ice better than other tires I've run on my Tahoe's and Burbs.
My test is the stop sign when departing our court, about a hundred yards from the house. On icy conditions I'll speed up some and then lock the brakes well before the stop sign so I can judge the conditions. The Pinza's stop shorter than the rest.
Same boat on tread life, only about 5K on mine. Recently made a run to the coast, and between the Pinza's, the Eiback sway bars and Billstein's I'm running front and back, the Sub' was rock solid on the twisty mtn road curves..
