Tire Load Rating

Naturally, the higher the load rating, the more weight a tire can support and handle more abuse, like braking, cornering, etc.. But even with the lowest rating, 4 of those tires (4 x 1279) will support more than the actual weight of your car and have a safety margin to boot.

I always try to get 4 trailer tires that will support a lot more than my car trailer weighs loaded and is rated for.
