wheel load limit says 690kg forged wheel
mounting on RL which has heaviest axle 1215kg which would require 607kg load per wheel minimum
i dont know how close can i get to the advertized wheel load limit safely

 

So, the wheel load limit is 690 kg (1,521 lbs). The GVWR on a 2012 Acura RL is 5,050 lbs.

4 x 1,521 = 6084 lbs.

Seems like you'll have more than 1,000 lbs. over the GVWR on the vehicle.

 

the front and rear axle weight is not same

 

Correct, but the weight (in stock trim) is mostly centered over the front of the vehicle. The passenger portion of the car is more centralized or even favoring the rear of the car. I would assume the car is no worse than a 60/40 weight split when empty, so 60% of 4,100 lbs (curb weight of 2012 RL) is 2,460 lbs.

2 x 1,521 lbs. = 3,042 lbs.

That means you're looking at over 500 lbs of weight can be distributed over the front wheels directly before you're coming close to the weight restrictions of the car. And, even with 4 passengers in the vehicle, its unlikely you're going to near that much force over the front wheels without having some seriously heavy set people.

 

this is what im talking about
i have same writings on mine
it says 690kg but doesnt say which bolt pattern or anything. i assume its for that specific wheel then since other bolt patterns are listed later

im worried about cornering with these mostly. becasue obviously its alot more load on the spokes when cornering.(i do drive it hard)
my old integra i acraped the rim on the pavement on one of the turns with low profile tires lol

 

As long as you're racing on the road, and not using the car as a rally car, you'll be more than covered with the load rating there.
