The UTQG ratings are somewhat subjective, but you can use them as a stating point in tire selection. The tire with the 400 rating is supposed to last longer than the tire with a 200 rating, but other factors influence tread life. For example, a tire with a UTQG treadwear rating of 400 might feel harsher than the same size tire with a rating of 200 at the same tire pressure. The Sport Fury AT4S also offers drivers a long tread life, a quiet ride, and enhanced grip and handling performance. You might want to research UTQG ratings and inquire as to which of the factors is most important for the feel you want in your Eldorado. Yes, Eldorado Sport Fury AT4S tires are a good choice for drivers of Jeeps, CUVs, SUVs, and light trucks who need an affordable tire that performance well on- and off-road. Given the job the front tires on an Eldorado have to do, the front tires need to be good quality. How old are the tires on your Eldorado? Some people replace tires based on age, not mileage. The tire sidewall will also have the month and year when that tire was manufactured. Several tires that fit your Eldorado will come with different UTQG ratings and each tire will feel different at the same pressure, based on how the tire manufacturer built the tire to achieve the UTQG rating that the manufacturer desired for that tire. The rating provides an indication of the tire's treadwear, traction, and temperature resistance, so that any tire can be compared to any other tire made by the same, or another manufacturer. What tires are on your Eldorado? Most likely, somewhere on the tire sidewall is a UTQG (uniform tire quality grade) rating. Comparing the Cadillac recommended pressure to the Bentley's recommended pressure is not a valid comparison.

The factory recommended tire pressure is usually for the factory installed tires, or tires of the same type and dimension.
