Today, I took my Sportage (23 GTLS HEV 227bhp) for its 10,000 mile service. During the service, I received the customary condition evaluation, which indicated that the tread depth of my front tyres had worn down to 4.8mm.

As someone with a scientific background, I decided to investigate the precise measurement of the tread depth of the Conti ECOContact 6 tyres. I inquired about this matter on the UK Continental website and received an exceptional response.

"No problem, I appreciate your prompt response with that information." Below, I have included further details on the EcoContact 6.

The initial tread depth of the 235/55 R18 104V XL EcoContact6 tyre is about 5.9mm. Please be aware that there may be a reduction in size when the tyre is removed from the mould.

The EcoContact 6 tyres are designed to minimise rolling resistance, which has a direct impact on fuel economy. One way to do this is by utilising a reduced starting tread depth, which helps to optimise energy loss via temperature regulation. It is important to note that tyres do not wear evenly in a straight line. As the tread depth increases, more heat is produced, leading to a greater friction rate. This might possibly impact the pace at which the tread wears off initially.

The initial depth of the tread is less than that of some other tyres. However, this should not undermine the tire's potential longevity, since the intricate compound used has been specifically formulated for this objective.

Based on a rough estimate, I anticipate receiving around 30,000 units from the fronts. However, I was so delighted with the reaction that I felt compelled to post it here.

Having worked in the tyre sector for an extensive period, I am well acquainted with the subject matter and can confirm its accuracy. Indeed, that is an exemplary reaction.

Aside from our Sportage, we also own an E Niro, which was acquired in July 2020 and has accumulated 24,500 kilometres. I am still using the original Michelins, and they seem to have enough tread to last for around 30,000 miles.

Are they measuring the tyre tread depth at the wear indications or until the tyres become completely smooth?

If they are indicating a rating of 5.9, then it may be inferred that they are referring to a wear indication. Most new tyres have a thickness of around 7 millimetres.

The tyres have worn down to a depth of 6mm, as previously said. Many people have claimed that after a year and fewer than 10,000 miles, the tyres had worn down to less than 5mm. The cost incurred due to reduced rolling resistance....

That is the reason why I like my All Season. I have not seen any alteration in the range of my electric vehicle (EV), which was my primary concern. Therefore, everyone is a winner.

I have equipped my electric vehicle with high-performance "Summer" tyres, and it is still achieving or surpassing the original official range that was provided when it was new, 7.5 years ago.

In my opinion, the low rolling resistance tyres have less impact on range and fuel efficiency, but significantly hinder the handling in wet and cold conditions.

An amazing response from them. Regrettably, I am one of the proprietors who have been afflicted by tyre punctures. The tyres are very lightweight, including a slim casing, presumably designed to save weight. Consequently, I have encountered several punctures caused by stones, a phenomenon that I have not before seen with any other tyre. After replacing three tyres within the first 10,000 miles of my vehicle (in addition to four repairs), I decided to switch to Pirelli tyres for the front wheels. I maintained one fixed Continental tyre as a spare to cover any unrepairable punctures that may occur on the rear wheel. I have had an additional three instances of tyre punctures throughout the last 8000 km. All of the rear tyres are Continental brand. Fortunately, all the damages were able to be fixed.

What is the reason for my complaining about this? Unfortunately, I have not had the opportunity to observe the durability of Conti's tyres since I had to often change them.

After comprehending the information, I should indulge myself by acquiring a spare wheel.

My Sportage still had its original rear tyres when I purchased it at 38,000 miles.
However, they were prepared to be replaced.

I am really satisfied with the Continental Contact 6 tyres on my Xceed. I find them preferable to the Michelin Premacy tyres on the Proceed, since they are quieter and perhaps provide more precision. However, there is a discrepancy of 10,000 units in terms of wear, since the current wear level is at 11,500 units. Nevertheless, the items are still wearing nicely.

The focus is not on the constructed depth, but rather on the rate of wear. This is shown in the original post (OP). Currently, the majority of producers begin with a thickness of around 7mm, as opposed to the previous standard of 8mm.Based on my recollection, I believe the Contis begin at a measurement of 6.5mm. As far as I know, it is primarily focused on reducing total weight and minimising rolling resistance.
I share the worry over the vulnerability of the sidewall to punctures or splits. I had to replace one after a mere 500 miles. Fortunately, this meant that I just had to purchase one item, eliminating the concern of varying depths among the back components.
