Centerline auto drag 15x8.5 on 69 Dart

Tight!

My 15x8.5 Auto Drags are 4.25 BS with a factory axle 8.75 on a Barracuda and 4-7/8 would get the tire close to the spring but may work. I seem to have about 1.5 clearance to the spring. 4.5 would be best but I think the dart wheel well is tighter than the Barracuda. That is with a 275/60/15. What size tire?
