Q: What is the ideal tire size for a square setup on Model 3?

For a Tesla Model 3 square wheel and tire setup, the most “ideal” tire size depends on your goal (OEM-like efficiency, sportier grip, or track focus). Based on the UP-03 square fitment recommendations in your chart, here are the most common “ideal” square tire sizes for Model 3:

Best all-around square tire size for Model 3 (OEM+ feel and efficiency)

• 245/45R18 (for 18×9 square)
• 245/40R19 (for 19×9 square)
• 245/35R20 (for 20×9 square)

These 245-width tire sizes are the go-to choice if you want a square setup that keeps the Model 3 balanced and maintains range-friendly efficiency

Sport square setup (more grip, still street-friendly)

• 265/40R18 (for 18×9.5 square)
• 265/35R19 (for 19×9.5 square)
• 265/30R20 (for 20×9.5 square)

Street and track square setup (maximum performance focus)

• 275/35R19 (for 19×10 square)
• 275/30R20 (for 20×10 square)
• 285/35R18 (for 18×10.5 square)
