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.

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.

29.05.2022 from Jamie Hewison
Bought these tyres as a bit of an emergency stop gap after somebody had slashed my tyres in a city centre car park, they were only supposed to be on for a few weeks until pay day and I could afford something better, however they’ve now been on for 6 months and have been used in all weathers, including a couple of muddy tracks. They perform really quite well, grip is very good in the dry, only a slight decrease on wet roads and better than expected in the snow. Although they’re not a mud tyre, they still handled the muddy farm tracks with ease. Fuel economy seems pretty much unchanged, road noise is slightly higher than a premium tyre but not so much that it becomes intrusive. Tyre wear is on par with others, I’ve done 10,000 miles so far and judging by the remaining tread, If I run them all the way down to 1.6mm, I think I’ll be on course for a 20,000 mile lifespan.

07.01.2023 from William
I originally picked Fulda Sport Control 2 because they had the lowest noise rating of any tyre I could find in comparisons. Some other tyres have a low noise rating but quieter tyres are hard to find. Fulda are a German manufactured brand which puts them in a different league from the tyres made in 3rd world countries in terms of quality but they're also middle priced so you're getting a good tyre for a good price. I've now had these all round on 3 cars and driven them over many years and 10s of thousands of miles and unless something better comes along I'll be sticking with them for the moment. Aside from being quiet I can't fault them on grip and wear although if they were less grippy or faster wearing I'd be prepared to accept that in return for the quieter running. A lot of modern cars have wheels which are far too large and the Fulda Sport Control 2 helps to mitigate the noise created by wide low profile tyres making the car much nicer to drive.
17.01.2020 from Wasim
It's a fine set of tyres. I don't push the car so can't really comment on its braking abilities and I haven't taken enough statistics to confirm any fuel efficiency differences from the manufacturer-provided tyres. However I can confirm that the moment I drove away from the garage with the new tyres, it was noticeably quieter, enough that some in my family noticed. Since buying the tyres the main roads to work have been torn up and the current temporary roads are really quite bad and will probably tear up the tyres far faster than normal roads would... who knows how bad the noise in the car would have been with the old ones.
04.12.2019 from Barry
A great performing tyre for the cost. Only area of concern is on damp roads and losing grip under hard acceleration (front wheel drive car, with lots of diesel torque). Very quiet compared to my last factory fitted Michelin.

Excellent tyre. Solid performance in wet and dry at high speed
