Nitto 555R and 555

[WizardsCobra]

I'm looking into getting a pair of new rear tires. Not sure if I should go with a set of Nitto 555 275-40-17 or get the Nitto 555R 315-35-17. I basically woundering which tire is going to last longer and be better for me. I really only drive the car on nice days. Maybe in the rain on occasion.
Thanks

The 555 has a treadware rating of 300. The 555R Drag Radial has a Treadware rating of 100.

The Drags Stick alot better but it depends if you want to change the Rs every 8-10K miles.

Both tires are great, you need to decide what your plans are for the car.
