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.

03.06.2025 from Ian Cornish
Medical problems have severely restricted driving over last 12 months, but I am satisfied with the tyres in town and across country. and the cost.
15.06.2024 from Brandon
I&#39;m quite an aggressive driver for want of a better phrase (I don&#39;t hang around) and have driven many cars on many different tyres including Bridgestone, toyo, advan, Goodyear, the list goes on. However, these davanti dx640 tyres are on another level, I live in the countryside in rural Norfolk UK, road conditions aren&#39;t the greatest even on dual carriageways but these tyres make driving a breeze. Traction under hard acceleration is extremely good, they hook up well and will barely spin up the wheels (my bmw 325i e92 is 225hp and spins most tyres you put on it) the same goes for hard acceleration in the wet, giving the driver a lot of confidence in the vehicle (especially rwd vehicles). Traction under hard cornering in the wet is probably the best I&#39;ve had from any tyre I&#39;ve ever used, very precise and the feed back is unreal, you can put the car exactly where you want it on the road and it seems this is possible even when you think it shouldn&#39;t be (wet slippery roundabouts are not a problem for this tyre even at speed). With that said, you can probably imagine the cornering capabilites of this tyre when being used in dry situations. Infact, it&#39;s hard to feel any real difference in its abilities between wet performance and dry performance. The fact I&#39;ve also done 5000 miles (not km) barely using any tread is great and I have no idea how they can make a tyre that handles as well as this, gives feedback as well as this, even in the wet, yet doesn&#39;t burn through rubber? It&#39;s crazy! These tyres may also be the quietest tyres I&#39;ve used, again surprising as usually for the performance of a tyre like this you get a fair amount of road noise. I&#39;d go as far to say these davanti tyres act like a semi slick in the dry, act like a wet racing tyre in the wet giving massive amounts of confidence to the driver, yet sound and have the longevity of a premium brand tyre that would cost you more than double the price.
18.09.2023 from Thomas kirk
These tyres would appear to be made from cheese and not cheddar, the soft kind like Feta. The merest hint of a curb and large chunks fall off the side wall. I will have to replace the two front tyres after 6 months and 700 miles to get the car through MOT. The previous tyres were on the car 8 years so it&rsquo;s not the drive, my wife who&rsquo;s not a brilliant driver to be honest, but the previous tyres stuck around for 8 years so I&rsquo;m pretty sure I won&rsquo;t be buying Devanti tyres any time soon. Appalling bad tyres.
19.05.2019 from Chris
I judge these tyres as I find and not by what I paid as these were cheap cheap cheap and by no means does the tyre represent the cost however these are my rear tyre on rear wheel drive car and often on wet roads I find the back slipping under heavy acceleration did not get this with my vredestein tyres but they were 100 cheaper for the pair agreed if I wasn&#39;t so heavy footed I would be fine I certainly wouldn&#39;t and didn&#39;t fit to the front on replacement as I spent more on stayed with my usual vredestein tyres overall a decent tyre for everyday use but not if you like to punch the throttle..

No grip on snow or ice whatsoever. If you have stopped on snow and tried to move all you get is wheel spin and a car that&#39;s sliding everywhere. On 90-degree road bends even at very slow speeds the car slides away from the turn. Talking about stopping power - it is not existent. On level roads, it takes a lot of distance to stop but if you&#39;re going downhill in very slippery conditions had an experience where it took about 100-150m to stop. Can&#39;t even fathom how these tires passed safety regulations. If you value your safety and your car DO NOT BUY!

19.03.2025 from Tina 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
20.08.2024 from Adam Galley
As good a more premium brands at half their price
01.10.2023 from George Wade
For the price I paid and the conditions I drove in such as -14&deg;c frost the tyres performed very well.
11.07.2022 from Greg
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.
