I wouldn't expect a "severe snow service rated" tire to be anything close to a LRR tire like the Enasave. I have to believe the rubber compound would be softer during cold weather with the Quatrac 5.
I would say my worn down $40 Federal SS657 tires didn't roll much differently than the Dunlop Enasave tires, but I was using a pair of both at the same time.
Most 165/65r14 tires are in the 13 pound range (give or take a pound or two).
Dunlop Enasave 01 A/S (340AB/no warranty) = 13 pounds
Bridgestone Potenza RE92 (250AB/40,000 miles) = 13 pounds - these are a LRR tire you may want to compare
Falken Sincera SN250A A/S (320BB/no warranty) = 13 pounds - current Mirage factory tire
Personally, I wouldn't spend my money on any of the above tires. Prices are higher than most & their UTQG ratings are nothing spectacular. If LRR tires are your thing, you may feel differently. I see no problem with that.
All-season alternatives
Federal SS657 (420AA/40,000 miles) = 14.7 pounds (factory closed that made this size)
Nexen N'Priz AH5 (460AA/50,000 miles) = 13 pounds
Kumho Solus TA31 (500AA/60,000 miles = 14.2 pounds
Winter tires
Dunlop Winter Maxx WM02 (snow tires are NOT given a UTQG rating) = 14 pounds
Nokian Nordman 7 = 14.1 pounds
Kumho Solus Wintercraft Ice Wi31 = 15.7 pounds
Federal Himalaya Kattura = 15.9 pounds
The Vredestein Quatrac 5 (400AA) is what I consider an all-weather tire. I will weigh one when I get them, because 12 pounds seems light by comparison to everything else. I haven't weighed any of the tires listed above. I just used whatever specs I could find on them.
There are lots of Chinese brands available these days. That was not the case a few years ago. If anyone has experience with any of them, I would love to hear about them.
Of all the tires I have purchased so far, I am the most impressed with the Nexen N'Priz AH5 pair. I got them on sale for around $50/tire. I feel their quality & thread pattern is superior to the Kumho Solus TA31 (but I have no complaints about the Kumho which seemed priced lower most of the time when comparing them).
