Ace,

Looking at the tires doesn't really tell anything about them.

For example, the NT555R is a straight-line drag racing tire. It has a wear rating of 100 compared with 400-500 for a street tire.

Here's the quote from the Nitto site "The NT555R was designed to achieve a balance between maximum dry performance and occasional street use." Please note the use of the words "dry" and "occasional."

If the wear rating and intended use match what you need, go for it! Put them on both ends of the car - they will look great, and since you won't do anything that could be considered stressful or risky with your right foot, they should work fine.

BTW, will your brake rotors fit inside 15" wheels?

Are you certain that only the switch to 15" from 17" wheels and tires will give you the esthetics you seek, or is there more to it, i.e., spring rates, tires (yes, tires!), suspension details such as swaybars etc and shock absorbers?

In other words, is the car you are comparing ride quality with identical to yours except for the wheels and tires? If it is, it might be logical to use the same tires and tire pressures as the other car.

Just askin'

Tom
