The General G-MAX RS is an ultra-high performance summer tire engineered for modern muscle cars, performance sedans, and sports coupes. Built with advanced compounds and directional tread design, the G-MAX RS delivers sharp steering response, confident cornering, and excellent wet and dry grip. With deep roots in motorsport and a storied race partnership with Saleen, General Tire has proven its performance pedigree on championship-winning Saleen Mustangs.
The 275/35R20 size offers a lower-profile, wider contact patch for aggressive fitments on Mustangs, Camaros, Chargers, and other high-performance vehicles. Reinforced shoulder blocks enhance cornering stability, while wide circumferential grooves help resist hydroplaning in wet conditions. The built-in Replacement Tire Monitor indicator makes it easy to know when it’s time for a new set, giving you peace of mind along with performance.
Whether for spirited daily driving or track-inspired performance, the G-MAX RS 275/35R20 is a direct fit for 20-inch wheels and is a proven upgrade for Saleen performance builds as well as factory performance cars.

Carriers and transit
Parcels ship by USPS, UPS or FedEx, whichever is most cost-effective. Typical ground transit after shipping is 1 to 4 business days within the continental US and 4 to 6 business days to Alaska, Hawaii and Puerto Rico. Weekends and holidays are not counted. UPS and FedEx do not deliver to PO Boxes, so please give a physical address.
APO/FPO, Guam and US Virgin Islands orders ship by USPS (70 lb limit per package) and can take up to 2 months. Canadian orders may owe taxes, duties and brokerage fees on delivery; these are collected by the carrier, not by Saleen Performance Parts.
Expedited shipping, where offered at checkout, speeds up transit only. It does not shorten Built to Order, Special Order or Pre-Order lead times.
Freight items
Large items such as hoods, fascias and body kits ship by freight. The freight charge is shown in your cart and at checkout before you pay. The carrier will call to schedule delivery, so please give a reliable phone number. Fees for lift-gate, inside delivery, limited-access locations, storage or redelivery requested or caused by the receiver are the customer's responsibility.
At delivery, please:
- Open and inspect the shipment with the driver present.
- Write a description of any damage on both your copy and the driver's copy of the delivery receipt, and have the driver sign it.
- Take 2 to 3 clear photos of the damage and the packaging.
- Accept the shipment. Refuse it only if the item is completely destroyed.
- Call us at 1-855-725-3361 within 72 hours so we can file the claim.
Damage not noted on the delivery receipt can cause the carrier to deny the claim. Keep all packaging until the claim is closed. Freight items are not returnable once delivered unless damaged, defective or incorrect.
Tracking
You will receive a tracking email when your order ships. You can also check status on our Track My Order page.
Lost or missing packages
If tracking shows delivered but you have not received it, contact us within 15 business days. Carrier traces take up to 8 business days for UPS and FedEx and an extra 7 business days for USPS. For higher-value orders a police report may be required before a replacement or refund is released.
Undeliverable or refused packages
Packages returned to us because of an incorrect address, a missed pickup, or a refusal without damage are subject to the original and return shipping cost and the 15% restocking fee.
