Yes.Didn't the 454SS come factory with 275/60R15s on 15X7 rims too?
BFG & Firestone recommend an 8" width for that tire size, but if mounting on a 7" wide... "Tire pressure should be dropped to 26 psi."
Normal psi is 35-36.
26 psi equals way too squishy sidewalls for my liking. Terrible handling & kills mpgs.
Running them @ 35 psi, which I do, on a 7" rim does cause the center of the tread to wear somewhat faster than the sides.
My corner-carving antics in the twisties evens that wear out, but only on the outer shoulders.
Even still, I usually average about 35-40,000+ miles out of a set of 4.
How was the truck lowered in the front? Springs or spindles?
BellTech spindles & their derivatives, McGaughy's, Western Chassis, CMS etc. will push the wheels out approximately 1/2"-3/4" per side.
DJM spindles maintain the factory track width.
Makes a diff when considering wheel offset.
My '97 @ 2/4. 275/60's. 7" wide wheel. B/T spindles.
Rolled fender lips. Trimmed LCAs.
They do rub occasionally at the bottom rear of the fenderwell.

454SS wheels = offset -25. Backspacing = 4 1/8".
A backspacing of 5.25" = 0 offset.
