Show your wheels

They look good to me…but it also looks like the OD on those 315s is only 25.7” (give or take). The performance tires seem to max out at this diameter which is too short for most of us. This is the main reason I gave up on my 17s.

What’s your final drive ratioOK?
I have 3.91 gears out back. My next set of tires will either be a 305/45 or a 345/40, if it'll fit an 11" rim. Both are closer to 28" tall. I'm gonna switch the tire, then see if going to a 3.21 is worth it. The 3.91 might be fine with a bigger tire, I used to run a 28x13.50, but can't remember that long ago. Lol
