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.

First time use Maxxis tyres, has worn on front wheels. Can&rsquo;t believe that tyres from budget class, for me a lot better than previous Uniroyal Rainsport 3. Quality to price, definitely recommended, probably will use again.
01.02.2019fromRichard
These tyres are quiet and grip well in the dry. They also brake well in the wet too and have good aquaplaning resistance. Fuel economy is fine too. However, on a wet road when going around a roundabout at anything over 25mph they loose lateral grip and the car slides sideways. If you push on the power then they completely break off and the car understeers. I am used to it now and drive gently but could be a bit dangerous for those who aren&#39;t experienced drivers. Also on cold damp roads they lose traction at low speeds when turning full lock in a manouvere, sending the ESP system off. I am disappointed because of this and won&#39;t buy again or recommend.
26.01.2019fromAlan
The worst fault i have found with these tyres are cornering. Even at relatively slow speed the vehicle slides, giving up grip rather easy. They remind me of a set of Falcons a purchased a few year back. Not good. Apart from that, an all round decent cheap tyre. Previous tyre i had on Accord were Michelon. A hard act to follow but at &pound;185 a corner !!!!

Good quality.. did a few burnouts as well and they look just like new :)

I thought about trying to get a refund. They make a terrible rumbling noise is one or two psi off optimum. Never had a tyre do that before.

Great tyres, good grip, excellent wear property, slightly noisy on road, excellent value for money &#x1F44D;&#x1F44D;

These tyres in my rear wheel drive BMW are grippy in the dry, but leave me yearning for more in the wet. The car will &quot;step-out&quot; if I punch it whilst the road is even midly damp. My tracking was done at the same time as having these fitted so that is not a factor. The car will also step out if the road is more greasy looking.

Tyres can be noisy over rougher surfaces but seem to be lasting well. Not really had any snow to speak of to test them on properly but perform well enough in very wet conditions on roads. Fuel consumption seems to be slightly worse than with summer tyres fitted but not too noticeable, getting around 35mpg at each fill up - was getting 35 to 38 with previous tyres.

21.02.2026fromAlan Marshall
Fabulous tyres and exceptional wear, considering the price point of these, especially given my driving style. I&#39;ll definitely see over 20000 miles on these tyres which I find remarkable on a heavy car with over 400hp. Could I have better grip, sure for twice the price. Do you really need it, even for having fun on UK roads, no! They are soft rubber though, so you&#39;ll know if your alignment is out, these didn&#39;t last long on my Merc V Class!
08.08.2020fromDean
Doing relatively high mileage of over 40k every year, I&#39;ve been through various different premium tyres over the years. Let me tell you, in the 5k miles on these tyres so far I&#39;d say they&#39;re pound for pound up there with premium tyres for everyday driving. I&#39;ve found them to be really good in the wet, no major drama with aquaplaning and my heavy right foot has encountered no issues in cornering. Strangely, I&#39;ve found that I&#39;m more confident with these in the wet than dry- they tend to be slightly unpredictable when pushing on. Not a massive issue by any means and shouldn&#39;t put anybody off, it&#39;s just highlighted by my spirited driving style! Wear seems to be decent so far, but as I said I&#39;ve only done 5k so far so too early to tell. All in all, great value for money and worth a try. On 20&#39;s, The Goodyear Eagle F1s that I had on previously were &pound;160 each, whereas I got these for &pound;115. 200 quid saved, and genuinely no worse performance. Well done Viking!
18.10.2019fromW Edbury
The car feels very safe cornering and braking is very good , it drives straight no wandering overall I&rsquo;m very satisfied with the set of Tyres.

I am a professional driver in my working environment (emergency services). These tires are rubbish. Any speeds over 50kph in wet weather will cause them to hydroplane.

These Trazano Z107 tyres were initially adequate as budget tyres but over time they have become noisy at speed and wet grip is now atrocious - with 5mm of tread still on the tyre. A regrettable purchase. I will revert to my usual Pirelli Cinturato which performed admirably right down to the tread wear markers. Lesson learned.

13.06.2025fromstevi
best tyres ever had them on Audi A3 TDI sport ,fiesta st .ford focus MK2,jaguar xj 3Ltdi best grip ever handles in wet like a great tyre does when dry grips so hard in the dry the engine struggles to go faster because of the grip tried all the named brands like Mitchellen ,toyos ,co rentals and the uni royals beat them ever time not just price but grip safety and handling too .never use any other tyre the 5s are better than the 3s but not by much . hard to improve on such a great tyre
02.11.2024fromA Pritchard
Great.
13.04.2024fromGeof Wassell
Driving within my own ability and the ability of the vehicle I choose to drive is what I do. The tyres on my car are part of the interface between driver and road. I prefer to drive with the tyres fully inflated in order to feel the feedback from the surface of the road through noise, suspension and steering, I ballance throttle and brake response with weather conditions, road conditions and temperature. Tyres with less grip just dictate that I should moderate speed and braking at an increased rate. Noisey tyres provide slightly better feedback than silent tyres. The road with current traffic congestion burden isnt the place for performance spirited driving but is the place where defensive driving must be used. I would describe my tyres as competent.
