What are Part Worn Tyres?

Part Worn Tyres are second hand tyres that are usually sold with around 50% of the original tread depth, having been driven for several thousand miles prior to being sold as second hand.

Are part worn tyres safe?

Quick answer, no! Unfortunately, 98% of part worn tyres are sold illegally - 34% are sold with dangerous and potentially life-threatening defects.
Because part worn tyres are not required to be x-rayed for internal structure defects before their sale, it’s virtually impossible to determine if any internal damage exists, or if the safety of the tyre has been compromised.  

The Protyre promise

Our tyre professionals will never agree to sell our valued customers used tyres. We know that part worn tyres with illegal repairs are putting lives at risk. These tyres very often have cracks and lumps and have very little tread left which does not make them a safe or cost-effective purchase for your car.
Protyre, your local tyre experts, offer a wide range of tyres from leading tyre manufacturers including Pirelli, Bridgestone, Continental and Goodyear.
However, we also understand that not affordability is sometimes the key criteria when it comes to selecting tyres so we have a large selection of Mid-range and Budget tyres for our customers to choose from.
If you are still unsure what tyres to select, the best option is to call into your local Protyre garage and talk to one of our experienced professionals. They will be able to advise you what the most cost-effective option is after taking your budget and driving style into account.

If you are unsure whether your tyres need replacing why not book a Free Tyre Check and let our expert technicians offer you the impartial advice you require. All of our garages within our UK network offer Free Tyre Checks so book today:

When you bear in mind that our prices represent the final amount that you will pay, this is the cheapest option in the long term. There will be no extra hidden costs for fitting or balancing the tyres or for disposing of your old tyres in an environmentally responsible way. If you would prefer to enquire about leading budget tyre brands over the phone, just give us a call.
Protyre take your safety very seriously. That is why we only employ the most experienced qualified tyre technicians and only ever sell brand new tyres from reputable manufacturers. That way, you know that you are getting a quality product and a top-rated service.
Finally, do bear in mind that a lot of tyre damage is not visible to the naked eye so the only way to be sure of your safety is to buy a brand-new tyre.

Why fitting part worn tyres is a false economy

Research by TyreSafe has shown those who buy part worn tyres will:
  • Buy tyres at least twice as often than those who buy new
  • Pay significantly more per mm of tread - TyreSafe reported that a part worn tyre will cost £6.33 per mm of tread while a comparable, in quality terms, new tyre would cost £5.32
  • Risk their safety – Part worn tyres are not required to have passed an inflation test prior to sale like new tyres

The more tread the better 

3mm is the recommended limit for tyre tread depth. The legal limit for tyre tread is a minimum depth of 1.6mm. Part worn tyres could have as little as 2mm tread.

Make sure your tyres are safe and legal

1,200 motorists a year are injured in an accident while driving on illegal tyres
Because you trust us with your safety Protyre do not sell part worn tyres. You will always drive away from one of our centres with safe and well fitted new tyres (8mm of tread).

Tread depth legal limit

More tread means more grip, meaning you stop quicker!
The legal limit (minimum depth) of tyre tread is 1.6mm, however the recommended limit is 3mm. Why is this so important?

Part worn tyres and the law

It is an offence for anyone to sell part worn tyres that do not meet the following requirements – irrespective of whether that tyre is fitted to a wheel rim:
  • The structural integrity must not be compromised; it should be free of large cuts and any bulges or lumps both internally and externally
  • The original grooves must still be clearly visible in their entirety and must be to a depth of at least 2 millimetres across the full breadth of the tread around its entire circumference
  • Tyres must have passed an inflation test prior to sale
  • No plies or cords should be exposed
  • Part worn tyres that have not been re-treaded must clearly show the relevant ‘E’ mark, alongside which ‘PART-WORN’ must be permanently and legibly applied in letters at least 4 millimetres high. These words cannot be hot branded or cut into the tyre
 Part-worn tyres that have been re-treaded must have one of the following:
  • BS AU 144b, 144c, 144d, or 144e markings on the side wall next to the ECE approval mark (which is required if first supplied as a re-tread on or after 2004)
  • Permanent markings to identify the original manufacturer and model
  • A speed category symbol and load capacity marking for tyres marked BS AU 144e

How To Avoid Part Worn Tyres

As amazing at it seems, your car is only in contact with the road surface through a very small area when compared to the size of the car itself - each tyre has a contact area approximately the size of your hand. This small area is critical to the control you have over your vehicle but is often ignored.
