What size tires go on a Chevy Express 3500?
The Chevy Express 3500 does not use a single tire size; it depends on year, trim, and wheel diameter. Common factory configurations include LT235/75R15 on 15-inch wheels and LT245/75R16 on 16-inch wheels, but always check your vehicle's door jamb placard for the exact specification.
As a large, commercial-style van, the Express 3500 has several stock tire options tied to its wheel size and payload capability. This guide lays out typical sizes and how to confirm the right fit for your specific van.
Common tire sizes by wheel diameter
These sizes reflect typical factory configurations for many Express 3500 vans. Exact tire size depends on model year, trim level, and whether the vehicle uses traditional passenger (P) tires or LT-rated commercial tires.
- 15-inch wheels: LT235/75R15E or P235/75R15 tires are commonly found on older or base-model Express 3500 vans.
- 16-inch wheels: LT245/75R16E tires are commonly installed on many 16-inch Express 3500 configurations.
- 17-inch wheels: Some conversions or higher-end configurations may use LT245/70R17E, but these are relatively rare as stock options for factory Express 3500 variants.
Because tire choices can vary by year and factory spec, always verify the exact size from your door placard or build sheet before purchasing replacements.
Load ratings and performance
Vans carrying heavy payloads typically use E-range tires (for example LT235/75R15E or LT245/75R16E). When replacing tires, ensure the new tires meet or exceed the original load rating and maintain appropriate speed ratings. Mismatched tires can affect handling, braking, and payload capacity.
How to verify the correct size for your van
To ensure you buy the right tires for your Chevy Express 3500, check these sources and steps:
- Check the tire placard on the driver’s door jamb for the recommended size and load rating.
- Consult the owner’s manual or the vehicle’s tire information label for the exact size and specifications for your year/model.
- If in doubt, contact a Chevrolet dealer or a trusted tire shop with your VIN; they can pull the exact original equipment tire size for your van.
- Consider wheel upgrades or payload changes; if you change wheel size, you may need to adjust tire size to maintain correct speedometer reading and load capacity.
Note that some models built with aftermarket wheels or cargo conversions may differ from the original equipment tires; when upgrading, ensure the new tires fit without rubbing and maintain appropriate load capacity and speed rating.
Summary
There is no single tire size for all Chevy Express 3500 vans. Typical factory sizes correspond to wheel diameter, with 15-inch wheels commonly using LT235/75R15E (or P235/75R15) and 16-inch wheels commonly using LT245/75R16E; 17-inch options are rare. Always verify the exact size on the door placard or VIN/build sheet before purchasing tires, especially if you’ve changed wheels or modified payload.
