We can only guess at why VW changed the recommended inflation levels. I am not sure that it always had to do with what tires came on the vehicle, as I believe that there are cases where the OE tire itself was not changed but the sticker data was. In other cases it occurred during, or shortly after, significant changes to the vehicle design (such as engine size/weight). The changes that VW made may have been the result of test track results, engineering data, tire manufacturer input, dealer feedback, warranty claim data, or any of a number of factors. The recommended specifications for a vehicle are generally based on a good bit of engineering and testing, not just randomly determined. Similarly, when a manufacturer makes a change to the specifications on a subsequent year there is usually a solid reason why they did so; it's not just an "off the cuff" decision. The most conservative course of action, of course, is stay very close to the tire inflation specifications that Volkswagen recommended for your vehicle, rather than second-guessing Volkswagen's engineers based only on wild guesses as to why they picked the numbers that they did. - Ron Salmon The Bus Depot, Inc. www.busdepot.com (215) 234-VWVW _____________________________________________ Toll-Free for Orders by PART # : 1-866-BUS-DEPOT |
