The current .110 wheels are good for the average home and club layout trackage and the finer.088" wheels should be used by advanced modelers with flawless track work...
IMHO the current RP25 wheel standards are fine and should not be changed.
Besides..
Think of this..
Who do you think is going to pay for the new tooling for the "improved" wheel?
Which begs the question.
At today's prices can we afford another $10.00 per car and we all know how some modelers will demand these new wheels be a standard for RTR cars.

In this months Model Railroader Magazine (May 2013) in an article entitled: 4 Technologies shaping model railroading's future, # 3 is an article about Rethinking the RP25 wheel standard, I found this article extremely interesting! It poses the idea that a larger radius in the corner between the tread and flange will do many good things for how our wheels interact with the rail head and how our cars negotiate our track. The author makes claims that I feel are all good and need to be looked at closely! I also feel (having been involved in the mechanical trades my entire life) that what he states makes perfect sense to me! Read the article and view the videos!
