What size tires can I put on my 2013 Chevy Silverado?

Common tire sizes for a 2013 Silverado vary by wheel size: 16" wheels typically use 245/75R16, 17" wheels use 265/70R17, 18" wheels use 275/65R18, and 20" wheels use 275/60R20. Always verify the exact size on your driver-side door placard for your specific build.

The 2013 Silverado, part of the GMT900 generation, was offered with multiple wheel and trim configurations, so tire sizing depends on your factory wheel diameter, cab/bed configuration, and drivetrain. Changing tire size can affect speedometer accuracy, gearing, ride quality, and clearance, so it’s important to consider diameter, width, offset, and load rating when planning a change. If you tow regularly or carry heavy loads, prioritize load capacity and stability in your selection.

Stock tire sizes by wheel option

Use the following as baseline references for typical OEM setups across common Silverado configurations. Individual builds may vary, so always check the placard on your door jamb for your exact specification.

• 16-inch wheels: 245/75R16


• 17-inch wheels: 265/70R17


• 18-inch wheels: 275/65R18


• 20-inch wheels: 275/60R20

These sizes reflect common factory configurations used on many 2013 Silverado models. Your exact vehicle may differ by trim, cab configuration, and options; always confirm with the door placard for your specific build.

Upsizing, downsizing, and compatibility considerations

Key fit and performance principles

Before changing tire sizes, understand how diameter, width, and offset affect clearance, speedometer accuracy, and ride quality. The goal is to stay within safe mechanical limits while achieving the desired look or performance.

Before changing wheel and tire sizes, consider the following guidelines to maintain safety and performance.

• Diameter change guideline: Try to keep overall tire diameter within about ±3% of factory to maintain speedometer accuracy and drive-system performance. For example, a factory 245/75R16 setup should stay within a compatible range when selecting new tires.


• Wheel width and clearance: Ensure the new tire width fits within the wheel well and does not rub on fenders, control arms, or suspension components. Verify offset and backspacing to avoid contact with brakes and suspension parts.


• Load and speed rating: Choose tires with equal or higher load index and at least the same speed rating as OEM to maintain payload capacity and performance characteristics.


• Drivetrain and trim considerations: 4WD, Z71, and larger diameter wheels can introduce clearance and suspension interactions. Some size combinations may require alignment or minor tuning.


• Professional confirmation: After selecting sizes, have them installed and rebalanced by a reputable shop. If you change diameter significantly, consider a wheel alignment and system calibration check.

In practice, many Silverado owners upsize by a single step in wheel diameter (for example, 16" to 17" or 17" to 18") or opt for the OEM 20" setup from higher trims, while keeping overall diameter close to original to preserve safety and performance.

How to confirm the right tire size for your exact vehicle

Your definitive source is the driver-side door placard, which lists the recommended tire size(s) for your specific model, engine, cab/bed configuration, and wheel size. The owner's manual and VIN-specific GM guides can also help. When in doubt, consult a tire or automotive service professional or your GM dealership for confirmation before purchasing tires.

Summary

For a 2013 Chevy Silverado, you can generally use 245/75R16 on 16" wheels, 265/70R17 on 17" wheels, 275/65R18 on 18" wheels, or 275/60R20 on 20" wheels, depending on your exact build. Always verify the exact size on your door placard and adhere to diameter, width, and load recommendations when changing sizes. If you’re unsure, seek professional guidance to ensure a safe and proper fit.

What size tires fit a 2013 Chevy Silverado?

The 2013 Silverado tire size varies by model and trim, but common sizes for the Silverado 1500 include 265/70R17, 265/65R18, and 275/55R20. For the heavier-duty Silverado 2500/3500 models, standard sizes are often 265/70R18 for 1500-series and 265/70R18 for 2500HD/3500HD 4x4, while dual rear wheel (DRW) models commonly use 235/80R17. 
2013 Silverado 1500

• 265/70R17: A very common size, often standard on models like the WT, LT, and Z71 with 17-inch wheels. 
• 265/65R18: Found on some Z71 and LTZ models with 18-inch wheels. 
• 275/55R20: Standard on LT and LTZ models with optional 20-inch wheels. 
• Other options: Some configurations might also use 245/70R17. 

2013 Silverado 2500HD/3500HD 

• 265/70R18: A standard size for many 2WD and 4x4 models. 
• 235/80R17: The standard size for dual rear wheel (DRW) models. 
• 245/75R17: Also listed as an option for some WT and LT models. 

Will 33s fit on stock 2013 Silverado 1500?

I have the same body style Silverado and was able to fit 33" tires with a 2 inch level to where they dont rub at all with some trimming. Yours would be a tighter fit due to the extra width but you could get them to where they barely rub or don't rub at all with some trimming.

What's the biggest tire I can put on a stock Silverado?

The largest tire that fits a stock Chevy Silverado without modifications is typically around 265/70R17 or 265/65R18 depending on the wheel diameter. For most models, a 285/70R17 or equivalent size tire will fit with a leveling kit or minor trimming, while anything larger generally requires a more significant lift. 
Stock fitment

• 17-inch wheels: A 265/70R17 is often the largest possible on stock suspension with no modifications. 
• 18-inch wheels: You can typically fit a 265/65R18 on stock suspension. 
• 20-inch wheels: A 285/55R20 is a common maximum size for stock 20-inch wheels. 

With a leveling kit or minor modifications 

• 33-inch tires: A leveling kit, like a 1.5 or 2-inch front leveling kit, is often enough to fit a 33-inch tire (such as a 285/70R17) without rubbing.
• Minor trimming: Some models can fit slightly larger tires, but this may require minor trimming of the plastic liner or mud flaps to prevent rubbing, especially when turning. 

For larger tires

• 35-inch tires: Fitting 35-inch tires generally requires a lift kit of 6 inches or more and will involve more aggressive cutting and modifications to avoid rubbing. 

How big of a tire can I fit on my truck without a lift?

On average, if your truck isn't lifted, you can fit tires up to 33”. In case the vehicle is lifted, you can find a good set of 37” or larger tires to fit. However, you must make some measurements to learn what your truck needs.
