-
Fuel Efficiency Underinflated tyres can increase fuel consumption by 3% to 10%. For a typical UK driver covering around 10,000 miles per year, this could equate to an additional £50 to £100 annually in fuel costs.*
-
Tyre Wear & Replacement In addition to fuel inefficiency, improperly inflated tyres wear out faster. This may force drivers to replace tyres more frequently, potentially adding £100 to £200 every few years.**
-
Uneven Tyre Wear Explanation for the above fact, overinflated tyres cause the centre of the tread to wear faster, while underinflated tyres cause wear on the edges.*
-
Higher Risk of Blowouts Low pressure can overheat tyres, increasing the chance of blowouts, especially at higher speeds.*
-
Poor Traction Incorrect pressure reduces the tyre's contact with the road, leading to decreased traction and stability.***
-
Extended Breaking Distances Underinflated tyres increase stopping distances, especially in wet conditions.*
-
Compromised Handling Poorly inflated tyres affect vehicle control making it harder to steer in some cases***
-
Reduced Comfort Overinflated tyres lead to a stiffer ride & less absorption of road bumps (Lord knows there are plenty of them nowadays!).***
-
Shorter Tyre Lifespan Both underinflation & over-inflation significantly reduce tyre life.***
-
Increased Risk of Aquaplaning Improperly inflated tyres struggle to disperse water, increasing the likelihood of aquaplaning.*
-
Potential for Suspension Wear/Damage Overinflated tyres do not absorb road impacts well, passing the shock onto the suspension.***
-
Damage to Wheel Alignment Incorrect pressure can cause uneven wear and affect wheel alignment.***
-
Increased Tyre Punctures Overinflated tyres are more susceptible to punctures from road debris.***
-
Higher Chance of Tyre Deflation Underinflation weakens the tyre sidewall, making it more prone to deflation.*
-
Increased Risk of Accidents As the combined result of reduced control, stability, and braking ability, there is a heightened risk of accidents.*
