Question for tire experts - Winterforce CV

I know we have another topic about the current heat wave here in southern New England, but I've got a winter tire question. 

My son is repainting the wheels for his SX4 and we will be mounting the continental pure contacts on them for warm weather.  Pic for attention:

So after all this work we were planning to keep them away from the salt and use my winter steelies from my Elantra, but they need new tires and since they are 15" we can't use the ones that had been on his wheels. 

I was looking on tire rack and saw they had Firestone Winterforce CV in the right size and on clearance for $53 (Link)

Looking at the specs they are heavier than the general Altima Arctic I was planning to get in the fall (29 lbs vs 21 lbs) but close to 1/2 the price. 

Any thought on using the CV tire on a 2008 Suzuki SX4 crossover?

From your link, the TireRack listing says 2017 production???

4 year old tires???

Tires are probably good for 10 years???

I was confused by the letter C at the beginning of the size.  Turns out it stands for Commercial

I'm not yet saying don't buy these but I recommend call TireRack and speak to someone before buying them. 

I saw the date was 2017, but figured indoor storage at TR would minimize age effects up to this point. Since they are winter tires I'd expect them to last maybe 4-5 seasons before wearing enough to need replacement. 

I'm wondering if the CV tires on small crossover/hatch would create issues with handling or other problems. 
 

Calling tire rack is a good idea and will save me from potentially buying something I won't  be happy with. 

Any of the TR sales people will tell you that production dates are basically irrelevant as long as the tires are unused and have been stored properly. Four years is getitng up there a bit even for that though IMO. I don't know if these are the same compound, but the original winterforce (the car version) wasn't great in cold conditions to begin with, and got worse with age. They were amazing rallycross tires but from the couple of winter events we did with them I'm not sure I would want them as actual winter tires. But for all I know the CV is a completely different compound that doesn't have that issue.

I have to think it's not a terrible decision.

How long do you think the SX4 will be kept for? Other decentish tires can be had for $100-150/set more. If you assume 1/3 less life it's not a huge difference. I don't know if commercial means a longer lasting tread. That might mean it lasts more miles, or it could mean they're hard and not as effective.

It's probably like putting LT tires on a truck that came with P-metric tires.

The will be heavier and have stiffer sidewalls to support the higher load rating. So a rougher ride.

Unsure if the compound would be any different

I put Firestone Winterforce tires on my wife's Legacy years ago. They were good in deep snow but no better than all-seasons in everything else. I stick to the Altimax Arctics for winter tirers now.

After a call to Tire track I've decided to wait and I'll just get the Altimax Arctic when it's closer to winter. 

He didn't have anything negative to say about the Firestone, other than the General would have better traction and handling in most conditions. 

So I'll stick with what I know and pay a little more for the better performance.  

In October all of the winter tire rebates come out.  For some reason the Conti viking 7 has a $70 rebate currently, or $330. They're decent, they tested well. I have a set but I'm not thrilled with them. My FiST is super nimble and I suspect it may expose the non-sporting nature of winter tires more than some other vehicles.

I ran the previous generation of Winterforce.  Freaking hated them. No idea if the latest ones are better or not.

I do LOVE the Altimax Arctic !
