Again, wrong argument. It doesn't matter what shorter sidewall height does or does not do. If we allow Joe Blow to replace his 225/45ZR13's with 225/45ZR15's it doesn't change the sidewall height. Your example using 14's only works out because there are no tires available in 14" with lower than a 50% aspect ratio. This fact only highlights the need to make this change. Tire manufacturers obviously find it unessesary to support these wheel sizes. Let's not wait until they decide 50% or 55% aspect ratios in 14's aren't profitable too!
