Before you order the 9's let me tell you why I wanted them. I wanted the widest rubber on the front possible. (245's according to my measurements, 255's were too scary) At the same time I wanted the 245's to be the smallest recommended size for the rim. This helps keep the tread flat on the track at really high side load levels. That happened to be a 9" width. If you want to keep the 225 or 235 aspect on the front I'd recommend 8.5" rims or you'll have the stretched look. It depends on what you want and what size tire you plan on. I can take a picture so you can see for yourself if you'd like.
