Frequently Asked Questions
What wheel size is best for my van?
The best wheel size depends on how you use your van.
- 18-inch wheels: best for comfort, load-carrying, and daily driving
- 20-inch wheels: ideal for style and sharper handling but slightly firmer on the road. Always make sure the wheels are load-rated for your specific van.
Do van wheels need to be load-rated
Yes. Vans carry more weight than cars, so wheels must be load-rated.
Using non-load-rated wheels can lead to cracking, deformation, MOT failure, or insurance issues.
What does "PCD" mean and why does it matter?
PCD stands for Pitch Circle Diameter - the measurement of the stud pattern. For example, a Ford Transit Custom is typically 5x160, meaning:
- 5 wheel studs
- 160mm diameter circle
Your new wheels must match your van's PCD.
How do I know if my tyres are load-rated?
Check the number of the tyre's sidewall - e.g., 103, 104, 109.
This is the load index.
Each number corresponds to a maximum weight the tyre can safely support.
Always use the rating recommended for you van or higher.
Will bigger wheels affect my fuel economy?
Slightly. Larger wheels (like 20s) are usually heavier and have wider tyres, which can reduce MPG a little.
Smaller wheels (like 16s or 18s) are lighter and typically better for fuel economy.
Do I need hub-centric rings for my new wheels?
You may. If the wheel's centre bore is larger than your van's hub, you'll need hub-centric rings to ensure a perfect fit.
They prevent vibration and ensure the wheel sits correctly on the hub.
How often should I check tyre pressure on a van?
At least once a week.
Vans are more sensitive to tyre pressure, especially when loaded.
Low pressure causes poor handling, uneven wear, and increased fuel consumption.
How tight should my wheel nuts be?
Always tighten van wheel nuts using a torque wrench.
Most vans require 110-180 Nm, but you should check your owner's manual or the exact torque setting.
Always re-torque wheels after 25-50 miles.
Can I mix tyre brands on my van?
It's legal, but not recommended.
Mixing brands can cause differences in grip, braking performance, and wear. For best results, use the same brand and model on each axle (front pair / rear pair).
What's the minimum legal tyre tread depth for vans?
The minimum legal tread depth in the UK (and many other places) is 1.6mm across the central 3/4 of the tyre.
However, most experts recommend replacing tyres at 3mm for safer braking - especially on heavier vans.
