OBS Chevy C1500 on WELD Ventura 20x8 & 20x10.5 Gloss Black Milled Wheels.

Oct 24th 2025

Reviving the OBS Era with Modern WELD Racing Style.

The OBS (Old Body Style) Chevy C1500 from 1988–1998 has evolved from a workhorse into a cult classic — and few upgrades transform its stance like a set of WELD Ventura 20x8 and 20x10.5 Gloss Black Milled wheels.

These wheels bridge classic truck design with modern forged aesthetics, giving your OBS Silverado or GMC Sierra a clean, performance-focused look that stands out both at shows and on the street.

The setup below shows how these Ventura wheels can turn a late-’90s sport truck into a true head-turner without compromising drivability or fitment geometry.

WELD Ventura Wheel Setup Details:

Front Fitment:

Wheel: WELD Ventura 5 Street Gloss Black Milled 20x8 | 5x127 (5x5) | 0 Offset | 4.50” Backspacing
Recommended Tire Sizes: 235/40R20, 245/40R20, 255/45R20
Notes: The 235 width provides slightly more clearance for lowered setups (4/6 drops or aftermarket control arms). Wider 245–255 sizes fill the fenders more on stock or mild drop configurations.

Rear Fitment:

Wheel: WELD Ventura 5 Street Gloss Black Milled 20x10.5 | 5x127 (5x5) | +13 Offset | 6.25” Backspacing
Recommended Tire Sizes: 285/40R20, 295/40R20, 315/35R20
Notes: 285 widths are a popular middle ground for trucks with moderate inner fender clearance. 295–315 sizes suit more aggressive drops or mini-tubbed builds.

Tire sizing may vary depending on drop kit, control arms, and inner clearance modifications. Always confirm with your suspension or alignment specialist before finalizing sizes.

Perfect Fitment for 1988–1998 Chevrolet C1500 & GMC Sierra 1500.

The OBS Chevy C1500 platform (1988–1998) shares geometry and hub specifications with many GMC and Chevrolet light-duty variants, allowing for excellent wheel interchangeability.

Chevrolet Silverado C1500 (1988–1998):

Bolt Pattern: 5x127 (5x5)
Compatible trims: Silverado, Cheyenne, Scottsdale, Sport, SS, and 454SS (converted 5-lug)
The 20x8 / 20x10.5 combination enhances stance while maintaining usable clearance.
Works on both lowered and air-ride setups with moderate drop spindle adjustments.

GMC Sierra 1500 (1988–1998):

Fits SL, SLE, and Sierra GT trims.
20x10.5 rear provides a deep, flush fitment ideal for step-side or fleetside beds.
Compatible with C-notch and flip kit rear configurations.

Chevy C2500 Light Duty / Tahoe / Suburban (1988–1999 5-lug models):

Shares the same 5x5 bolt pattern and hub size.
Direct upgrade for sport trucks or SUVs retaining factory-style hubs.
Delivers a strong visual upgrade while supporting heavy-duty tire loads.

Why the 20x8 & 20x10.5 Staggered Setup Works?

This combination provides a perfect visual and performance balance:

20x8 front wheels maintain crisp steering and suspension travel.
20x10.5 rears fill out the bed line and rear quarter arches, emphasizing the truck’s classic squarebody design.
Staggered stance allows for high-grip tires while keeping daily drivability intact.

The +13 rear offset aligns beautifully with OBS frame geometry, giving a proportional rear track width without poke or rubbing when paired with the right tire size and drop configuration.

Tire Pairing and Stance Recommendations:

Fronts:

235/40R20 → Best for deep front drops (4/6 or 5/7).
245/40R20 → Clean flush look on mild drops.
255/45R20 → Great for near-stock ride height or air suspension.

Rears:

285/40R20 → Ideal for limited inner clearance or step-side applications.
295/40R20 → Balanced flush stance for most drop kits.
315/35R20 → Maximum width for custom or mini-tubbed trucks.

Each of these pairings maintains proper rolling diameter while optimizing wheelwell fitment. Always check clearance at full compression, especially when running C-notches or narrowed rears.

Style and Stance: Where Performance Meets Heritage.

The WELD Ventura Gloss Black Milled finish offers a perfect contrast against OBS paint colors — from factory white and Onyx Black to Victory Red or Emerald Green.

This combination embodies both performance and heritage, giving the truck a timeless profile that works equally well on classic restomods or modern LS-swapped builds.

When paired with performance tires like Nitto NT555 G2 or Toyo Proxes ST III, the Ventura provides confident traction with a street-performance look that fits the OBS ethos perfectly.
