Non-widebody · 245/45ZR20 square
The default answer for a reason: huge dry grip, wet manners that flatter the chassis, and it outlasts everything else this sticky. If you drive the car the way the badge suggests, start here.
An all-season that grips far above its price and shrugs off Florida downpours. The right call if the car is a daily and you refuse to own a second set of wheels.
Cheap enough that roasting a set does not hurt, grippy enough that the car still hooks. The honest pick for cars that see the water box more than the highway.
Widebody · 305/35ZR20 square
On the widebody the 4S turns the car into a different machine — the launch traction the narrow body never had. Priced like it, worth it.
What many widebodies wore from the factory. Strong dry grip, a touch louder as it wears — a fair like-for-like swap if you liked how it left the showroom.
Always confirm against the tire placard on your driver-side door jamb and your actual wheel widths before ordering. Fitments here cover common factory and community setups — years and packages vary.

Questions owners actually ask
Can I stagger a non-widebody Scat Pack? Yes — with wheels. The common move is 20x9 front / 20x10.5 rear running 245/45R20 + 275/40R20 (diameters match within 0.4% — verify any pair here). On factory 9-inch wheels, stay square: a 275 pinched onto a 9-inch rim crowns the tread and grips worse, not better.
Do I have to match front and rear brands? Across an axle: never mix. Front-to-rear: matching families is best; a stickier rear compound in the same family is the sane drag-lean setup.
Why does my rear wear so fast? 485 hp, open throttle, and a square 245 — the math does itself. Wider rear or softer right foot; there is no third option.
