Tires are the most underrated performance upgrade on any SRT vehicle — and the most commonly neglected. Every bit of the engine’s power reaches the road through four contact patches roughly the size of a sheet of paper each. The wrong tire wastes that power. The right tire transforms the car.
Jeep Grand Cherokee SRT / Trackhawk (Stock: 295/45R20)
The GC SRT and Trackhawk come on Pirelli Scorpion Verde all-season tires from the factory — a compromise tire that prioritizes quiet and comfort over outright performance.
Best all-season replacement: Michelin Pilot Sport AS 4 — Dramatically better dry and wet grip than the stock Pirellis. Year-round capability with genuine performance character. This is the right tire for most SRT drivers.
Best summer performance: Michelin Pilot Sport 4S — The benchmark ultra-high performance summer tire. Transforms the GC SRT’s handling — sharper turn-in, more confidence mid-corner, better feel through the steering. Not for winter use.
Best budget option: Continental ExtremeContact Sport 02 — About 20-30% cheaper than the Michelin with similar performance. Good choice if you drive hard and replace tires frequently.
Best for drag strip: Mickey Thompson ET Street SS — Semi-slick drag radials that transform 60-foot times. Not for regular street use but devastating on a strip.
Dodge Durango SRT (Stock: 295/45R20)
The Durango SRT’s extra weight makes tire choice especially important. You need a tire that handles the mass under hard braking and cornering while surviving regular towing.
Best all-around: Michelin Pilot Sport AS 4 — The weight of the Durango benefits from the AS 4’s stability. Better wet weather performance than a pure summer tire, which matters more in a daily-driven SUV used for towing.
Best summer performance: Goodyear Eagle F1 Asymmetric 6 — Excellent high-load performance with good heat resistance under the kind of sustained hard braking the Durango’s weight demands.
Dodge Charger / Challenger SRT Hellcat Widebody (Stock: 305/35R20 rear, 275/40R20 front)
The Widebody’s staggered fitment gives you more rubber. The stock Pirelli P-Zero tires wear quickly with 700+ horsepower going through them.
Best street replacement: Michelin Pilot Sport 4S — The gold standard for Hellcat owners. Noticeably better grip and more consistent performance than the stock Pirellis, with better longevity under normal use.
Best for the drag strip: Mickey Thompson ET Street SS (rear) — Keep street tires up front, put drag radials on the rears. This combination has run deep 10s on stock engine Hellcats.
Ram TRX (Stock: 35×12.50R18 Goodyear Wrangler All-Terrain)
The TRX’s stock Goodyear all-terrains are actually very capable — designed for exactly what the TRX does. Most owners keep them.
Best street-biased upgrade: BF Goodrich All-Terrain T/A KO2 — Better on-road manners than the stock Goodyears with similar off-road capability. Quieter at highway speeds.
Best for serious off-road: Nitto Ridge Grappler — A hybrid terrain tire — better off-road than an all-terrain, more street-friendly than a mud-terrain. The go-to for TRX owners who actually use the off-road capability.
Essential Tire Accessories
Every SRT owner should have these:
- Digital tire pressure gauge — Check pressure weekly on high-performance tires. Pressure affects both grip and wear significantly.
- Quality torque wrench — Always torque lug nuts to spec (150 ft-lbs on SRT vehicles) after any tire work.
Key Tire Maintenance Rules for SRT Vehicles
- Check pressure weekly — performance tires lose pressure faster than standard tires
- Rotate every 5,000-7,500 miles — SRT vehicles are hard on rear tires due to power delivery
- Replace all four on AWD vehicles when worn — mismatched tires stress the transfer case
- Don’t cheap out — a $150/tire saving on a 475-707hp vehicle is false economy
