Nitto Tires Launch New Tire Design at SEMA 08

[DriverzInc]

Tim stick with the 555 front and the 555r for the rear, since the treads will match, and you need that 555r in the back.

The NT05 is definitely a street tire, not a drag radial like the 555r.
It will also of course depend on where you live. Here in Cali, it hardly rains like I know it does in other parts of the country, and always pick a tire that corresponds with the type of driving you will be doing.
