275 60 15 looks damn good on a Duster. I went with the 295/50s. Springs haven't been moved in but they are super stock Springs so I don't have any problems with that thankfully car had 225 60s on the back but every time you mat the gas the car'd try to turn all the way around on you, at the very least go sideways. That's with a 2200 stall. Now I need more stall LOL
