The 300S most commonly runs 245/45R20 tires (SRT-trim 300s can run a staggered 245/45R20 front and 255/45R20 rear setup instead). Below are eight real 245/45R20 tires spanning budget touring to performance, with pricing checked this session for this specific size — 20-inch, low-profile sizes like this run notably more expensive than smaller sizes, which the prices below reflect honestly rather than smoothing over.

Buying tips
- Standard 300S trims run 245/45R20 all around; SRT-trim cars can run a staggered setup with 255/45R20 on the rear — check your door-jamb sticker or current tire sidewall before ordering.
- 20-inch low-profile sizes like this run notably more expensive than smaller sizes on the same tire line — the prices above reflect this size specifically, not a generic ‘starting at’ figure.
- If your 300S is AWD, replace all four tires together (not just the worn pair) to avoid drivetrain strain from mismatched tread depth.
