PM me and I can help you out with a good price on the Sumitomo and possibly some other brands.
For the standard wheels I would be going with the Sumitomo ZIII for sure, they are quiet, good gripping in wet & dry as well as giving good mileage and it is one of the only tyres I have ever sold that I have never had any complaints about and they are Japanese made.
