I received 205 Gislaveds, they have a load rating of 1356 lb; the OE Primacy tires have a load rating of 1477 lb. TG's 215 Gislaveds are rated 1433 lb.

Looking at the weight stickers, it says my '02 Aero has a GVWR of 4430 lb, and the maximum load capacity is 920 lb. So does this mean the car is 4430 lb-920 lb or 3510 lb without stuff in it? Do gasoline and the other fluids have to be considered in the calculation?

Anyway, am I also correct in thinking that GVWR is the maximum the car would weigh, fully laden with people/cargo in it?

If so, 1356 lb * 4 tires gives 5424 lb, so am I correct in thinking this is comfortably above the GVWR of 4430 lb?

Oh, and one last question: isn't the tire's load capacity rating at the maximum inflation pressure, and if so, how to adjust calculation for a on-the-road, real-life, typically lower inflation pressure?

Thanks in advance,
Jason
