load index

chrischhorn

I work at Costco and we are very strict about load ratings. Basically match manufacturer specs or higher. Lower load rating will make you more prone to pot hole wheel damage and blow outs from those pot holes. You think 88lbs isn't a lot? X4 and you're basically 350lbs short of correct support. Not only that but your tires won't wear right as it can only be inflated so much. Over inflate to compensate and now your running the risk of bubbling the sidewalls in potholes or a blowout but a lot of people do run lower load rating tires. To each their own but I'm fine searching for tires that need meet the load rating. The reason load ratings vary is cause a lot of Mercedes, VW and BMW need XL (extra load) tires to properly support the vehicle. This limits their choices but its comes with the vehicle and the extra weight that comes with them. Just my .02

Ok im not arguing with you on these points, im just wanting explanation why it is that when you do a search on tires.com and put your information in on the website that the load ratings are different from one tire to the next as far as load rating goes. Case in point, for stock rim and tire setup on the Z here is a list:Falken 98y front 96y rear, BFG 98y front 96y rear, Yokohama S Drive 94y front 96y rear, Re760 Bridgestone 98y front and 100y rear.

Also, I looked at the OP and researched the load numbers. Again it WON'T matter due to the fact that each tire at 96 is capable of 1565lbs, so x4 and that gives you a total load capacity of 6260. Gross vehicle weight on our car is 3232. max payload on our cars if im not mistaken is around 600lbs? I am kindly stating sir that you are incorrect when referencing passenger car tires to sportscar tires.

As i stated, my .02. Take it or leave. Manufacturer specs is what they are for a reason. If you don't like it, you can find a shop that doesn't care either. Good thing there isn't any extra forced pushed onto the tires when you hit potholes, bumps, dips, or lips in the road that cause extra compression on your tires in quick bursts....... Lucky..... Kinda like saying, a 200 lb man jumping is only landing at 200lbs of force.

I agree, and this type of thread should be a sticky for educational purposes. Easy example: scale reads real high the moment you step on it, then backs down to your real weight.

Motions create extra load on the tires. The debate is really about how much extra and what the safe margin is.

There must be a formula somewhere...
