Your almost letting yourslef in for possible disappointments.
Good things do cost more money.
The price for that tire and wheel isn't bad, BUT the wheel must be rated at least 2600 pounds each. If less than that, they will fail.
Also, when you get off brand tires, keep in mind what you can and cannot do to replace one, if your away from home and have a blow out.
Major brands are everywhere, unknown brands are not.
On the other hand, carrying one for a spare, is always a good idea.
