Can I Change My Car Wheels From 16 Inch to 18 or 20 Inch?

     A Complete Guide to Legality, Safety, Tyres, Fitment and Getting It Right Changing the wheels on a car is one of the most popular modifications people make. A larger set of alloy wheels can completely transform the appearance of a vehicle. A car that looks ordinary on standard 16-inch wheels can look much more aggressive and sporty with 18, 19 or even 20-inch alloys. But what happens if your car currently has 16-inch wheels and you want to fit 18 or 20-inch wheels? Follow Car Guru DIY Blog Is it legal? Will the car still pass its MOT? Will the larger wheels damage the suspension? Will the tyres rub against the arches? Will your speedometer become inaccurate? And perhaps most importantly:  how do you make sure the modification is actually safe? The short answer is that increasing wheel diameter from 16 inches to 20 inches can be possible, but you cannot assume that any 20-inch wheel will fit simply because the bolt pattern looks correct. The wheel, tyre, suspensi...

Rolls-Royce Boat Tail: The Car That Turns Into a Hidden Picnic Suite

There are luxury cars. There are coachbuilt cars. And then there is the Rolls-Royce Boat Tail a machine so unconcerned with ordinary automotive priorities that one of its defining features is not horsepower, speed, or lap times.

It’s a hidden outdoor dining room.

At the press of a button, the rear bodywork opens with theatrical precision and reveals a complete picnic and hospitality setup: tables, refrigeration, serving equipment, and a deployable parasol. It feels less like opening a trunk and more like opening a cabinet built by a luxury yacht maker.

Rolls Royce Boat Tail

Calling it a “boot” almost feels inaccurate.

The idea: what if a car unfolded into an event?

Most cars treat luggage space as dead volume.

The Boat Tail treats it as architecture.

From the outside, the car already looks unusual. Its proportions are stretched and calm rather than aggressive. The rear narrows and sweeps backward in a shape inspired by classic boat sterns and vintage coachbuilt automobiles which is where the name comes from.

But the real surprise is hidden under the rear deck.

When activated:

  • The rear body panels open outward in a synchronized butterfly motion.
  • Two cocktail tables emerge.
  • Refrigerated compartments become accessible.
  • Custom storage trays reveal cutlery and dining accessories.
  • A parasol extends upward for shade.
  • The entire setup transforms into an outdoor hosting space.

The engineering challenge isn’t simply “hide objects in the trunk.”

It’s that all of this must deploy silently, align perfectly, survive weather, resist vibration, and still close with the precision expected of a hand-built Rolls-Royce.

That means furniture tolerances inside a moving vehicle.

Why this feels stranger than supercar technology

Luxury engineering often aims for performance:

  • faster acceleration
  • lighter materials
  • more computing power

Boat Tail goes in another direction entirely.

Its question seems to be:

How do you engineer convenience so thoroughly that leisure becomes mechanical?

The result is oddly fascinating because nothing about the system solves a normal transportation problem.

Nobody needs hidden cocktail tables.

Nobody needs deployable dining furniture in a car.

But that’s almost the point.

This is engineering used as expression rather than necessity.

The same way a mechanical watch can exist in a world of smartphones.

More yacht than automobile

The Boat Tail doesn’t really behave like modern automotive design.

Many details borrow from luxury marine design:

  • flowing rear proportions
  • deck-like surfaces
  • handcrafted finishes
  • compartmentalized storage
  • hospitality-first layout

Instead of maximizing cargo volume, the rear section acts like a hidden lounge.

It’s closer to opening a premium sailing yacht than opening a hatchback.

That connection matters because the car was developed as an ultra-exclusive coachbuilt project built around individual client preferences rather than standardized production.

The hidden complexity nobody sees

The most interesting engineering is often invisible.

To make something appear effortless, enormous effort disappears underneath.

Think about what has to happen for the picnic suite to work:

  • Motors deploy without visible drama.
  • Mechanisms stay hidden when closed.
  • Refrigeration remains integrated.
  • Surfaces must remain beautiful after repeated movement.
  • Weather sealing has to protect everything.
  • The car still has to function as… a car.

A normal trunk only opens.

This one stages an experience.

Luxury as choreography

The Boat Tail reveals something unusual about modern luxury.

For decades, expensive cars competed by adding more:
bigger engines, more screens, more features.

This takes another route.

It creates a moment.

Arrive somewhere scenic.

Press a button.

Watch the rear deck separate.

Tables appear.

Shade unfolds.

Dinner begins.

It’s absurd.

It’s extravagant.

And it’s also one of the clearest examples of luxury engineering becoming performance art.

The Rolls-Royce Boat Tail may not be the fastest, loudest, or most technologically advanced car in the world.

But it might be one of the few that can honestly claim:

its trunk turns into furniture.
