For owners of the powerful Srt Chrysler 300, selecting the correct tire size is crucial for maintaining optimal performance and handling. The SRT models are equipped with sophisticated computer systems that monitor wheel speed, and improper tire sizing can interfere with these systems, hindering performance. This guide explores the recommended tire sizes for your SRT Chrysler 300, ensuring you maintain that signature SRT driving experience.
Originally, SRT-8 models came with two tire configurations directly from the factory. The first option featured 245/45R20 tires on both the front and rear axles, utilizing Goodyear Eagle RSA tires. Alternatively, some models were equipped with a slightly staggered setup, using 245/45R20 tires in the front and wider 255/45R20 tires on the rear, fitted with Goodyear Eagle F-1 Supercar tires.
The key consideration with the SRT-8’s computer system is its sensitivity to rear tire spin relative to the front. To avoid triggering the system unnecessarily, it’s vital that the overall diameter of the rear tires is either the same as or marginally larger than the front tires. Keeping this in mind, several tire fitment options have proven successful for SRT Chrysler 300 owners looking for replacements or upgrades:
-
245/45R20 All Around: Mirroring the first stock option, using 245/45R20 tires on all four corners is a straightforward and reliable choice. This setup maintains the intended tire diameter balance and is compatible with the SRT’s systems.
-
245/45R20 Front and 255/45R20 Rear: Emulating the second factory configuration, this staggered approach provides a slightly wider contact patch at the rear for enhanced traction, while still adhering to the diameter requirements for the SRT computer.
-
255/45R20 All Around: For those prioritizing tire rotation to maximize tire lifespan, or seeking a robust winter tire solution, a 255/45R20 setup on all four wheels is a viable option. Notably, Pirelli offers its Scorpion Snow/Ice tire in this size, making it a popular choice for winter driving, as opposed to the 245/45R20 size which lacks this specific snow tire option from Pirelli.
-
245/45R20 Front and 275/40R20 Rear: This combination is favored by many SRT Chrysler 300 enthusiasts seeking a performance upgrade. The crucial advantage here is that despite the wider rear tire, the overall tire diameter remains virtually identical between the front and rear axles. The 245 width up front ensures good turning clearance, while the 275 rear tire represents the widest recommended fitment for the stock wheel width, maximizing grip and enhancing the vehicle’s stance. Several tire manufacturers offer tires in this specific combination, including popular performance-oriented choices like Toyo Proxes4 and Nitto Invo (both brands under the same parent company). Kumho also produces tires in compatible sizes, though their offerings tend to lean more towards all-season performance.
It’s important to exercise caution when exploring tire options beyond these recommended sizes. While many tires might technically “fit” the wheel, a significant number are designed for trucks and SUVs. These tires, despite matching the diameter, are often engineered with different performance characteristics that can negatively impact the handling and responsiveness of your SRT Chrysler 300. Sticking to passenger car performance tires in the recommended sizes will ensure your SRT maintains its intended driving dynamics and exhilarating performance.
