225/40 R18 Tyres

 

 

Confirm 225/40 R18 Tyre Size

No need to overthink about your 225/40 R18 tyres — it's printed right on the sidewall, shown as three numbers separated by slashes: 225 (width), 40 (profile) and 18 (rim diameter), followed by the load and speed rating. This should also appear on the vehicle's tyre placard, usually found inside the driver's door, or in the handbook.
The wrong size affects handling, braking and speedo accuracy — check the sidewall or placard directly rather than going by model alone, since trims differ. Not sure? Simply visit Ossett Tyre House — staff are always happy to guide customers through the options.

Which 225/40 R18 Tyres To Choose?

Depending on how and when the car's driven, a few seasonal options are worth considering for your 225/40 R18 Tyres:

  • Summer tyres – with less sidewall to flex and absorb bumps, a good summer compound in 225/40 R18 keeps handling sharp on warmer, drier roads, though grip drops off once temperatures fall below around 7°C
  • Winter tyres – the low profile of a 225/40 R18 already limits some road contact in poor conditions, so a softer winter compound and deeper tread help claw back grip on cold, wet, or icy surfaces
  • All-season tyres – a practical middle ground for this size, useful for drivers who want to avoid swapping tyres twice a year without needing peak performance in either extreme

 

FAQS

How much do 225/40 R18 tyres cost?

Prices vary by brand, roughly from budget options through to premium performance tyres — Ossett Tyre House stocks options across that range, with an exact price available in branch or via the online booking tool for the make and model.

Can I fit a different size instead of 225/40 R18?

It's best to stick with the manufacturer's specified size, as fitting a different one can affect handling, braking distance, and even speedometer accuracy. Any change should only be made against the manufacturer's approved alternatives, not by guesswork.

What tyre pressure should 225/40 R18 tyres be?

This depends on the vehicle, not the tyre size — the correct pressure is listed on the tyre placard inside the driver's door or in the handbook, and it's worth checking regularly since low-profile tyres can be less forgiving of under-inflation than a standard profile.
