What size tires are on a 1999 Chevy Suburban?
The 1999 Chevy Suburban did not have a single universal tire size: it varied by the factory wheel package. The most common configurations were 235/75R15 on 15-inch wheels for base models and 245/75R16 on 16-inch wheels for LT and upgraded trims. Verify the exact size on your vehicle because aftermarket wheels or special packages can change the OE specification.
In this article, we break down typical stock sizes by wheel setup, explain how to confirm the exact size on a given Suburban, and offer guidance for tire replacement. This should help you identify the correct dimension without guessing, whether you’re shopping for replacements or restoring a classic family SUV.
Stock tire sizes by wheel configuration
Because tire size is tied to the wheel size and trim package, the most common OE sizes you’ll encounter on a 1999 Suburban fall into two broad categories: 15-inch wheels and 16-inch wheels. Below are the typical sizes associated with those configurations.
Base models with 15-inch wheels
- P235/75R15
This size is the standard fit for many base Suburban models that rode on 15-inch wheels in 1999, offering a balance of ride comfort and off-road capability that GM trucks of the era aimed to deliver.
LT models and 16-inch wheels
- P245/75R16
For LT trims and models equipped with 16-inch wheels, the P245/75R16 size was a common OE configuration, providing a slightly larger contact patch and a bit more stance on the road.
Note: Some rare or dealer-installed packages, as well as aftermarket wheel upgrades, can result in other sizes. Always confirm with the original equipment on your specific vehicle if accuracy is critical for replacement decisions.
How to verify the exact size on your Suburban
To confirm the precise OE tire size for your specific 1999 Suburban, use the following steps. These methods will help ensure you select tires that match the vehicle’s factory specifications and clearance.
- Check the driver's door jamb sticker. It lists the recommended tire size(s) by model and wheel configuration for that vehicle.
- Inspect the tire sidewall. The size appears in a format like P235/75R15 and indicates width, aspect ratio, and wheel diameter.
- Consult the owner's manual. It often documents the original equipment sizes for each trim level and wheel package.
- Use the VIN to fetch original equipment. A dealership or GM’s service records, and reputable online VIN databases, can reveal the OE tire size associated with your exact build.
When replacing tires, aim to match the original size, load index, and speed rating. If you opt for a different size, be mindful of potential changes to speedometer accuracy, handling, and load capacity. If in doubt, consult a tire professional or your local GM dealer.
