Seems like a good deal. However, the old adage of "if it sounds too good . . . " may be applicable.
Something to consider: Allowing me to share what I recently learned about tires and tire dealers in the good old USofA a few months ago.
Be aware that most often when there's a "Manager's Special" or "4 for the cost of 3" "deal", you need to make certain you are not buying old tires.
Yes confusing - "How can I be buying old tires, if they are new". You'll ask the question "are these new tires?" and be told, "yes - they've never been mounted before - and look they have all the little nubbie things on them". So you are not being outright lied to, but in the same respect you may not be getting the whole truth. And, sometimes to no fault of the person answering your question - they may not be aware . . .
Make certain you check the DOT date on the side wall. Another confusing part "What the heck does it look like and what do the numbers mean? Typically the DOT area where the code is can be hidden on the side of the tire most likely "not" to be visible until you crawl under the auto, sometimes it is on both side walls.
To the point - the area you need to find will be small and molded into the side wall closest to the bead/wheel area. It will read DOT (there may be other numbers and/or letters - like Xf 45hT) with 4 numbers following the letters:
The key is: the 4 numbers at the end is the "manufactured date".
The first 2 numbers are the week of the year, and the last 2 numbers are the year.
EXAMPLES:
DOT . . . 0109 = 1st week of "2009" = 1 year + old (should be fine)
DOT . . . 5197 = 51st week of "1997" = (too old)
DOT . . . 3405 = 34th week "2005" = (too old)
Now that we know this - here's what the rule of thumb is (and in Europe - Law) we should not purchase tires that were manufactured more then 36 months prior to date of purchase - "period" (and in Europe dealers/manufacturers are only allowed to recycle these "old" tires = not permitted to sell).
Reason, obvious if you rationalize a bit - although the tires are "new" because they have never been installed on a wheel before - they are, in-fact "not new" because they have been drying-out (= dry rotting) just because of sitting around for years. Unfortunately, this dry rot will not be obvious until the tires are pressurized and accumulate some miles - heat and cool cycles - roughly 200 - 1000 miles depending . . .
So, the point is buyer be "educated and cautious" of the "good deals" out there.
Not to rain on your parade, but I want you to be aware of something I learned that will help me keep my family safe. And, to help keep you & yours safe on your "new" tires.
The tires you are looking at may very well be outstanding and a great bargain and fall well within the criteria of being less then even 9 months old - so the best thing you can do is look at the tires "before" they're installed "and" insist that all 4 have the same week & year stamp on them. If they are not all date matched, and you are told "this is what we have" then go to another Sears. As a customer you have the right to anything you want before you pay one single cent - take full advantage of that right. Walk back to the warehouse and help select "your new tires" - making certain date matched and not old.
Last note: I've purchased 4 sets of tires "on-line", 1 set for my wife's Volvo, 1 set for my wife's old car (Miata) and 2 sets for my truck (both Nittos - very happy with longevity - 1st set 60k, ride, lack of "hum = noise" and wear). When I learned about the "Date Code" on the side wall I immediately checked the tires on both (remaining in my possession) sets of tires and was delighted to find - after comparing date on the sales slips - that when I received the tires they were less than "8 weeks" old Oo.
I hope my "long" reply may help: 1-inform you (and anyone else that reads this), 2- help deciding on "to buy or not to buy" and 3 most importantly keep you and your family safe going down the road.
Good luck with the new tires.
