I have 17inch wheels and run 32pounds..........M5 front and rear bars........runs perfect.Here in New zealand we have many beautiful windy roads and you really get the full benefit from the above setup.........I guess with straight freeway driving in traffic, you would never notice the difference.
All the best.
On mine with the stock 16" wheels I'm supposed to have 30psi front, 35psi back. I typically run it 1-2 psi higher than that in the summer.
