What Is Plus Sizing? A 'How To' Guide for 4x4 and Off-Road Drivers
Whether you're pushing through muddy trails in a Land Rover Defender, tackling rocky terrain in a Ford Ranger, or simply upgrading your vehicle’s stance and capability, plus (or ‘minus) sizing your wheels and tyres is a powerful way to boost both performance and style.
What Does "Plus Sizing" Mean?
Plus sizing refers to increasing the size of your vehicle’s wheels and tyres beyond the Original Equipment (OE) specifications. Common among 4x4 and off-road enthusiasts, plus sizing allows for a larger wheel diameter and wider tyre footprint—resulting in improved handling, stability, and a more aggressive look. It's not just about aesthetics; it's about performance where it counts.
Many 4x4 owners choose to upgrade from their factory wheels to larger steel wheels or modular rims like our GOJOS, paired with chunky off-road tyres like our Roadcruza range. This setup not only looks the part but also enhances grip, ground clearance, and off-road durability.
Plus Sizing Breakdown for Off-Road Vehicles
Whether you drive a rugged Defender, Wrangler, or a lifted pickup, understanding the levels of plus sizing can help you choose the best fitment for your build:
For example purposes
Plus Zero
Keep your original wheel diameter but opt for a wider tyre with a lower aspect ratio.
Benefits: Enhanced contact patch and improved off-road traction.
Ideal for: Those looking to beef up their off-road tyres without changing wheels.
Plus One
Increase the wheel size by 1 inch, while reducing the tyre’s sidewall profile.
Example: Upgrading from 16" to 17" wheels.
Benefits: Sharper handling on and off-road, more stylish stance, and better stability at higher speeds.
Great for: Ford Ranger owners seeking a balance between road and trail use.
Plus Two
Increase wheel size by 2 inches, with a proportionally wider tyre and lower sidewall.
Example: Moving from 16" OE wheels to 18" steel modular wheels.
Benefits: Enhanced road handling and trail toughness.
Perfect for: Overland builds and aggressive 4x4 upgrades.

Choosing Wheels for Off-Road Plus Sizing
For extreme durability and a rugged look, many 4x4 drivers choose:

-Heavy-duty alloys built for off-road conditions
These wheel options, paired with chunky all-terrain or mud-terrain tyres, can transform your vehicle’s performance in mud, gravel, snow, or sand.
