CARDIAGTECH.NET offers expert solutions to optimize your off-road experience. Elevate your ride with durable and high-performance wheel upgrades for your Defender, enhancing its capability and appearance.

1. The Low-Profile Tire Problem on Land Rover Defenders

Land Rover produces incredibly capable 4x4s. Since the Discovery 3 in 2005, they’ve fitted low-profile tires. These look good outside urban cafes but compromise off-road capability and are prone to damage. The new Defender L663 is no exception. These tires sacrifice performance for aesthetics, leaving drivers wanting more.

TuffAnt rims offer a robust alternative to low-profile tires, enhancing off-road capabilities and durability for Land Rover vehicles

Understanding Tire Profiles

Let’s define some key terms:

• Low-profile tire: A tire with a small amount of rubber between the rim and the road, resulting in a short sidewall.
• High-profile tire: A tire with a larger sidewall, offering more cushioning and flexibility.

There’s no fixed definition, but on tires around 30-32″ overall diameter, a 20″ rim would be low profile, and a 17″ would be high profile. The lower the profile, the shorter the sidewall. Compare these two:

TuffAnt offers both 18-inch and 20-inch wheel options, allowing for customized tire profiles to suit different driving needs and preferences

Why Taller Sidewalls Matter Off-Road

The taller the sidewall, the better for off-roading. It allows the tire to flex and mold over uneven terrain. You can drop air pressure without worrying about the rim damaging the tire or hitting the ground. Reducing air pressure improves off-road performance in rocks, mud, sand, or snow. Upgrading your L663 Wheels is a key investment in your vehicle’s overall performance and durability.

The Risk of Low-Profile Tires

A Range Rover Sport with 20″ rims shows how low-profile tires struggle with obstacles. The tire is crushed against the rim, risking damage to both.

Another Range Rover had this exact problem:

Low-profile tires are already damaged off-road. Land Rover fits low-profile tires to their vehicles. If you are an off-roader, you want the smallest diameter rim you can fit: 17 or 18 inches, not 19, 20, or 22.

2. The Ideal Wheel Size for Off-Roading with Your Defender L663

Land Rover insists on fitting their cars with huge rims. Most L663 Defenders come with 20″ rims with 265/60/20 tires. These rims are too large, allowing only a 163mm tall sidewall before any weight is applied. A 275/70/18 tire allows another 25mm of sidewall, 15% more. Every millimeter helps. Prioritizing the right L663 wheels not only enhances off-road capability but also ensures a safer and more enjoyable driving experience.

Benefits of Smaller Diameter Rims

Smaller diameter rims offer several advantages:

• Increased Sidewall Height: More flexibility and cushioning for better off-road performance.
• Reduced Risk of Damage: Less chance of damaging the tire or rim when off-roading.
• Improved Traction: Better grip on uneven terrain due to increased tire flex.

3. TuffAnt’s Solution: 18″ Wheels for Land Rover Defenders

I hate low-profile tires on 4x4s and have spent time explaining the problem. I’m pleased to see a solution from Land Rover wheel specialist TuffAnt. They offer 18″ wheels to fit modern Land Rovers, including the Defender. If your Defender doesn’t already run 18s, then if you have a D200, D240, D250, or P300, unbolt the old wheels and pop on a new set of 18s. CARDIAGTECH.NET is your premier destination for securing these high-quality TuffAnt wheels, designed to elevate your off-roading experience.

Why Choose Aftermarket Wheels?

Carmakers charge a fortune for their wheels, and Land Rover is no exception, so it’s cheaper to go aftermarket.

The Challenge with D300 and P400 Defenders

There’s a problem with the Defender D300 and P400 – these vehicles run higher-power engines and have larger rear brake calipers than the other models. This is unusual, as normally the front calipers are larger than the rear. 18″ wheels won’t fit on the D300 and P400 rears because of those large calipers.

TuffAnt’s Innovative Brake Modification

TuffAnt has fitted calipers from another Land Rover product to the rear of a Defender. This gives the required clearance. But that’s a brake modification, and brakes are critical, so that change needs engineering signoff. This is what TuffAnt have done, taking their car to a test track for formal engineering certification and signoff. Choosing the right L663 wheels is a critical decision that impacts both performance and safety.

Testing the Defender with modified brakes to ensure safety and compliance with Australian Design Rules standards

The tests involved loading the Defender to GVM, and performing a series of high-speed consecutive stops in accordance with the Australian Design Rules standards.

4. Legally Running 18″ Wheels on D300 and P400 Defenders

L663 Defender D300s and P400s can legally run 18″ wheels, provided those wheels are TuffAnt, the caliper is provided by TuffAnt and fitted by an authorised installer (there will be one in each Australian capital city) who will then provide a modification plate. CARDIAGTECH.NET guides you in ensuring your wheel modifications are both performance-enhancing and legally compliant.

Important Considerations

• Professional Installation: You can’t DIY, and you can’t use any other kit to get the certification.
• Legal Implications: If you DIY, you’re running an illegally modified vehicle with implications for insurance, or lack thereof.
• Rim Specifications: Ensure rims are load-rated to at least the original rim specifications, and the offset is within legal limits.
• Service Mode: You also need to put the Defender into “service mode” for the caliper swap.

5. The Benefits of TuffAnt 18s for All Defenders

TuffAnt 18s for all Defenders is great news, as it’s a disappointment to see capable vehicles like Land Rovers crippled with low-profile tires. Another bonus is weight saving. I calculated the weight of a 255/70/18 tire running a TuffAnt alloy wheel and Goodyear Wrangler at 33kg, whereas the same Wrangler tire but in 255/60/20 on a 20″ rim would be 39kg. Contact CARDIAGTECH.NET for expert advice on the optimal wheel and tire combinations for your Defender.

Weight Saving Advantages

That’s 6kg per wheel, or 5 x 6 = 30kg weight saving, or 30kg more payload. That weight saving is both unsprung mass as well as rotating mass.

The Bottom Line

Land Rovers are capable despite, not because of their tires. Now you can fix yours.
