What should i do?

I have 10 spoke SS rims on my car with 275 40 17s on all four. I need new back tires badly and i'm tryin to decide if i want to go a lil wider or stay with the 275. Give me some opinions!!

I always stay at the 275's. They're stock spec, and cheaper. It doesn't look like you're running an insane amount of horsepower so no need for anything bigger really. My .02.
