Generally,
roof racks designed to carry skis are built to handle the weight of several pairs of skis and ski poles. However, it is crucial to ensure that you do not exceed the weight limit specified by the manufacturer to avoid damaging the roof rack, your vehicle, or causing any safety issues while driving.
Keep in mind that the weight of your skis, ski poles, and the ski carrier itself will all contribute to the total load on the roof rack. Additionally, the weight limit may be different for various vehicle models, so it is crucial to verify the appropriate weight capacity for your specific roof rack and car.
