Chevrolet S10 Bolt Pattern, Wheel & Tire Sizes
TL;DR
Brazil/LatAm Chevrolet S10 (1995-2022 spans) is widely documented as 6x139.7mm, M12x1.5 studs, roughly 100.1-100.3mm center bore; figures for the 2023-plus facelifted S10 were not reliably confirmed here, so check your door placard or a wheel shop before ordering rims.
Which S10 this guide covers
Chevrolet has sold two unrelated trucks under the S10 name. This page is about the Brazilian and Latin-American S10 pickup, built by GM do Brasil since 1995 and sold across South America (and, in a later generation, globally alongside the Colorado). It is not the same vehicle as the older North American compact S10 (1982-2004), which used a different platform and different wheel fitment - if your truck is a US-market S10 from that era, the figures below do not apply to you.
What we could verify
Independent wheel-fitment references consistently list a 6x139.7mm (6x5.5 in) bolt pattern with an M12x1.5 stud thread for the S10 sold in Brazil from the 1995-2011 first generation through the 2012-2022 second/third generation built on GM's global midsize-truck platform. Center bore is reported as approximately 100.1mm to 100.3mm - sources differ slightly on the exact decimal, so treat this as a close approximation rather than a guaranteed figure for every trim.
What we could not confirm
We could not reliably corroborate exact bolt-pattern or center-bore figures for the facelifted S10 sold from roughly 2023 onward. Some retail wheel-fitment listings also mention a 6x114.3mm pattern as an alternative for newer trucks, which conflicts with the more detailed fitment-database entries we found. Rather than guess, we recommend verifying this generation directly on the vehicle or with your dealer.
Where to get the exact figures for your truck
- The driver's door placard (open the door, look at the pillar) often lists tire size and sometimes wheel information.
- Your owner's manual has a wheels-and-tires section with exact factory specifications for your trim.
- The markings stamped on your current wheel and tire (e.g., size, offset) tell you exactly what is already fitted.
- A tire/wheel shop can measure bolt pattern and center bore directly if you are unsure.
| Generation / years | Bolt pattern | Centre bore | Stud thread | Stock wheel sizes | Common tire sizes |
|---|---|---|---|---|---|
| 1st gen, Brazil/LatAm (1995-2011) | 6x139.7mm | ~100.1mm (approx.) | M12x1.5 | 15-16 in | 225/75R15, 235/75R15, 235/70R16 |
| 2nd gen, global platform (2012-2016) | 6x139.7mm | ~100.3mm (approx.) | M12x1.5 | 16-18 in | 215/70R16, 235/75R16, 265/70R17, 235/50ZR18 |
| 2nd gen facelift (2017-2022) | 6x139.7mm | ~100.1-100.3mm (approx.) | M12x1.5 | 16-18 in | 245/70R16, 245/65R17, 265/65R17, 265/60R18 |
| Facelift (2023-present) | Not reliably confirmed - check your placard | Not reliably confirmed | Likely M12x1.5, verify locally | Verify on vehicle | Verify on vehicle |

Frequently asked questions
Is the Chevrolet S10 sold in the US the same truck as the Brazilian S10?
No. The original US-market Chevrolet S10 (1982-2004) was a smaller, unrelated platform with its own bolt pattern. The Brazil/Latin-American S10 discussed on this page is a different, later truck built by GM do Brasil starting in 1995, and it is the S10 still sold in Brazil, Argentina and other markets today alongside the Chevrolet Colorado.
What bolt pattern does the Brazilian Chevrolet S10 use?
Wheel-fitment references consistently document 6x139.7mm (6 lugs, 139.7mm apart) with an M12x1.5 stud thread for both the 1995-2011 and 2012-2022 generations. We could not reliably confirm whether this changed for the 2023-plus facelift, so verify before buying wheels for a newer truck.
What is the center bore of the Chevrolet S10?
Sources place it in the range of about 100.1mm to 100.3mm depending on model year, though figures vary slightly between references. If you are fitting aftermarket wheels, confirm the center bore matches your hub or use a hub-centric ring to take up any gap.
Where can I find the exact wheel specs for my specific S10?
Check the driver's door placard, your owner's manual's tires-and-wheels section, or the size markings already stamped on your fitted wheel and tire. These are the authoritative sources for your exact configuration, since bolt pattern, offset and load rating can vary by trim, engine and drivetrain (4x2 vs 4x4).
