Identify the size of your tyre
The exact dimensions of a tyre can be found on the sidewall printed mark. The graphic shows how to read properties and dimensions of the tyre:
 
/
SPEED INDEX:
The speed index indicates the maximum speed intended for the tyre. Up to this value, the manufacturer guarantees optimum operation with the appropriate tyre pressure. The maximum speed allowed for this vehicle is given in the vehicle owner's manual; this information can be used to select the appropriate speed index for the tyre. The speed index is the last mark on the sidewall of the tyre.
 
Load Index
Permissible maximum axle load per tyre in kg. To be found in the registration certificate or vehicle registration document or read directly from the tyre (two-digit number). It is permitted to fit a tyre with a higher load index.
 
Driving safety despite puncture
Runflat tyres are puncture-resistant tyres with reinforced sidewalls. This creates the so-called run-flat property. In the event of damage, this allows the vehicle to continue driving up to a distance of approx. 100 km (and even beyond depending on the product) at a maximum speed of 80 km/h, even if the pressure has been completely lost. Run-flat tyres even prevent the tyre rubber from jumping off the rim in the event of a loss of air pressure. A flat tyre is therefore still a flat tyre, but it loses some of its drama. Note: All run-flat tyres are marked with the symbol "RSC" (Runflat System Component) and may only be fitted in vehicles with a functioning air pressure control system!
 
Tyres with increased load capacity
Reinforced tyres are designed for higher loads than normal tyres. They can be identified by the designation 'RF' (reinforced) or also 'XL' or 'Extra Load'. They are used on vans, minibuses, off-road vehicles, etc. However, their mounting alone does not automatically result in higher load capacity but also requires a correspondingly higher air pressure. Furthermore, the load capacity index specified in the vehicle documents continues to apply.
 
Tyres with extra high load capacity
The "C" in the term C tyres stands for "commercial". These tyres are specially designed for commercial vehicles. These can be, for example, lighter trucks, delivery vans, flatbed trucks or panel vans. In other words: vehicles that have to move higher loads at a comparatively lower speed. The multi-ply reinforced C tyres are therefore even more load-bearing than reinforced tyres.
 
Mobility-optimised tyres
A tyre with a sealing layer on the opposite side of the tyre tread. In the event of a puncture (e.g. by a nail), this layer blocks any loss of air, even if the foreign body causing the puncture is still in the tyre. It is not necessary to stop or change the tyres immediately at the roadside.

Tyres optimised for electric vehicles.
Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.
 
x
Original equipment quality: optimum adjustment to the vehicle
Tyres with a special OEM marking on the sidewall, e.g. "MO" for Mercedes-Benz, were developed in cooperation with a specific car manufacturer and the tyre industry. These tyres have been homologated by the vehicle manufacturer and are a perfect match for a specific model. They have been specially designed to highlight or further improve the performance characteristics of the car in question, thus representing the culmination of a state-of-the-art fine-tuning process that perfectly complements the latest technological developments in the automotive industry. Tyres with manufacturer's markings can of course also be used on other vehicles.

My size tire was not available on the site, it&#39;s 21&quot; and not 18&quot;. My experience is maybe unique to Tesla cars, but it has only 1-2mm left after 17000 km. With Hankook and Pirelli, I&#39;ve gotten better milage... The tire can suddenly lose grip in aqua planing conditions, which I did experience once on the highway - and not with any other tire. But maybe all tires would have this issue under the same conditions. My main issue is that the tire wears our very quickly especially on the rim area, making tires wear out prematurely and they easily puncture if not detected (can see white threads, but not visible easily if on the inner rim). Some of this is likely due to Tesla ABS system activating easily in sharp curves, as I have not experienced these issues with other car brands. Both model 3 and model S have this issue. These tires I need to replace quicker than 17000 km as one of tires has just approx 1mm thread.

I chose the Pilot Sport 5s for my car for 6000 miles of arduous driving, leading a classic car rally around all of Greece. We were heavily laden and driving hard on very mixed surfaces. The Pilot Sports never let us down and showed impressive grip throughout. Even better, 10,000km later they have worn remarkably little, and very evenly. The sister car was on Toyos which admittedly are cheaper, but showed a LOT more wear.
22.08.2022fromJustin
Size = 255/40/19. I had the Pilot sport 4 on the front, went for the PS5 on the back as they were just available and they were great. I would definitely go for them again but I just changed my car and it looks like Michelin do not support the new size tyres (305/30/ZR21) but I will keep checking Michelin.

A good value tyre, fit and forget - unremarkable but not in a bad way. They&#39;re only vice is they&#39;re not terribly puncture resistant and one has had to be replaced rather than repaired
02.11.2024fromCF
On my second set of these tyres, excellent grip and handling. Good in the wet too
26.09.2024fromCB
I replaced the original MG4 Continental tyres with these Yokohamas after about 20,000 miles. These new tyres have so much better grip in all weathers. These new ones are however a little less comfortable on UK road surfaces (which causes more road noise) as the Continentals were really comfortable with little road noise.
06.10.2023fromVictor
On wet roads, the cornering capability is reduced compared to Bridgestones, however these tyres cost 30% less. All in all, for mixed driving, it&rsquo;s a great all rounder, especially since it&rsquo;s very reasonably priced. A decent everyday tyre. We&rsquo;ll see how long it lasts, but seems promising, so far. Noise level is quite low too.

Performed well in regarded to grip levels both wet and dry, did aquaplane more than the Pirelli&rsquo;s P zeros but absolutely unbearable road noise and harshness. Yes I had 22&rdquo; wheels with a very low profile but when compared to the OEM Pirelli P Zero &amp; Scopions I&rsquo;d avoid these if you want to enjoy your drive.
01.06.2022fromIan
Superb grip on twisty country roads I&#39;ve had minor spin when pulling away on wet surfaces, but have driven through very wet conditions with no concerns. Noise is more from poor road surfaces than the tyres and they&#39;re very quiet on quality roads. Still surprised by how little they&#39;ve worn in 6 months.
05.09.2020fromElaine barclay
Changed to these tyre as wasnt happy with the grip on the ones I had. Would definitely recommend great grip in wet and dry very good braking and comfortable and not any louder then any other tyre I have had.

19.03.2025fromTina F
Definitely the best tyres I&#39;ve owned to date. I&#39;m driving 28years and always had an issue or two with tyres, so decided to go for all season tyres online so I could see reviews and specs . Bought full set of 4 Rotalla after seeing reviews. I am not an overly cautious driver let&#39;s say, and I would take roundabouts at a fair enough speed, previous tyres would struggle on wet days. I instantly felt a huge difference on roundabouts, and grip on breaking on colder mornings . I&#39;m extremely happy with the road grip and performance on sunny days AND colder frosty mornings. My car feels safer to drive for sure. I drive in city, rural and motorway roads regularly so I can say I have tested these tyres fully. At a guess I&#39;ve done approx 2.5k+ miles on these tyres. Fuel efficiency has improved slightly, but my car is old, so wasnt expecting miracles. I&#39;m changing cars soon and I just hope I can get these tyres or very close to, for the new car. That&#39;s how happy I am with them. Only reason I might have not given 5 stars all round is because I cannot judge the noise or fuel based on my own cars age and knowledge of noise level. Highly recommend tho, delighted I took the chance
20.08.2024fromAdam Galley
As good a more premium brands at half their price
01.10.2023fromGeorge Wade
For the price I paid and the conditions I drove in such as -14&deg;c frost the tyres performed very well.
11.07.2022fromGreg
Really good tyres, couldnt fault them. Great grip in wet and snow. Deff. will buy them again. Why pay 100+ per tyre when You could have pair of these for this money.
