Curb rash (Outer rim): Moderate to heavy curb rash is present on all four wheels. The close-up image shows significant scraping and gouging along the outer rim edge, with material removal extending approximately 5-8mm in width around affected sections. The damage is visible from 2m distance on multiple wheels. At least two wheels show pronounced curb contact marks visible in the overview images, particularly on the upper right and lower right wheels in the set photos.

Curb rash (Inner rim): The inner rim barrel shows noticeable scraping and abrasion marks visible in the close-up images. Light scratches and scuffing are present along the inner lip area, likely from tire mounting and dismounting operations. This damage is only visible up close during inspection.

Paint peeling / Corrosion: Significant paint deterioration is observed on the inner barrel and spoke surfaces. The rear face image reveals extensive paint flaking and peeling across the spoke sections and inner barrel area, covering approximately 40-50% of the inner surface. The center hub area shows heavy paint loss with exposed bare metal. Some corrosion spots are visible where paint has lifted, particularly around the lug nut holes and center bore. This deterioration is cosmetic but indicates long-term environmental exposure.

White rust / Corrosion: White oxidation deposits are visible on the inner barrel surfaces in the rear face photograph. The corrosion appears as scattered white spotting and staining across the unpainted aluminum sections. Light surface corrosion is present around the center hub bore area. The outer faces remain relatively clean with minimal visible white rust, though some light contamination is present near the rim edges.

Suspected distortion: No obvious bends, cracks, or structural deformation are visible in the provided photographs. The wheels appear to maintain their circular shape and spoke integrity. However, given the visible curb rash damage, measurement with specialized dial indicator or run-out gauge equipment is recommended to confirm true roundness and absence of lateral or radial distortion.

Special notes: These are genuine Nissan Skyline GT-R BNR33 forged wheels, size 17x9JJ with +30 offset. The rubber valve stems appear to be original equipment and show age-related deterioration, replacement is recommended before mounting new tires. The tires currently fitted are 235/45ZR17 94W and appear to have moderate to low remaining tread depth based on wear indicator visibility. The overall condition suggests the wheels are usable but would benefit from professional refinishing of the inner barrels and outer rim edges if a clean appearance is desired. The structural integrity appears sound for continued street use pending proper distortion verification.
