My car came with 17" wheels and it is time to get new tires. Our local roads are not exactly the smoothest and the 17"s are a bit bumpy for my liking. I have ridden and driven a car with 15"s and this is the way I would like to go. The question I have is more targeted at the proper application of tires. I am going to run 325/50/15 on the rear and 275/50/15 on the front. Is there any downside to running the Nitto NT555R on both the front and rear of the car? I drive the car aggressive related to acceleration but I am not overly aggressive in the turns. I have limited experience with tire selection and I wanted to stay away from putting different brands of tires and tread patterns on the front and rear wheels. I have looked into the Nitto summer tire that matches the NT555R but it was not available in a 15" size. The only other option I have come across is the MT Street ET Street R but it looks more like a dedicated drag tire and not something you would want to run on all 4 corners. Thanks for your help or any experience you can lend. Below are a few notes that directly relate to my use of the car.

*I drive year around

*I do not drive in the rain and I will not be making my tire selection related to any rain or damp conditions.

*I think Avon tires are the best but they are not an option so please refrain from telling me how great they are as I have experienced them first hand. I am vain and want to go with the wider tires in the rear this is primary reason I am not selecting Avons at this time.

*I have not opportunity to track the car. This is a 100% street car with a 427 Windsor power train
