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.

Tyre developed for electric vehicles. These tyres can also be used without hesitation on vehicles with other drive systems.

11.03.2022fromDavid
I have been an Avon fan for nearly 50 years and currently have 4 of their tyres on my SUV. I've just received an MOT advisory warning that the front 2 are perishing, after only 2 years and 6000 miles of normal use (ie no off road use) - see photo. I've submitted a warranty request to the company and will update this review, based on the response I get. UPDATE - The response I've received from Avon is that I have to return my car to the garage who fitted the tyres, then get them to remove the tyres and send them back to Avon. That means I have to leave my car sitting on the garage forecourt on its rims for as long as it takes Avon to uplift, examine and report on the tyres. If Avon deem the ZX7s to be faulty, they will refund on the basis of how much tread is left compared to new, but if they think the tyres are 'within normal specification', they will return them to the garage, to be refitted. As an alternative, Avon suggest that I simply buy 2 new tyres, before sending my originals back. That way I don't lose the use of my car, but what happens if they decide that they won't honour my warranty claim? I'll then have 2 sets of tyres! And who pays the garage to do all this work? If ever there was a procedure designed to hamper a consumer making a warranty claim, then this has to be it. No goodwill from Avon, no acceptance of what an accredited long standing garage or a qualified MOT inspector says. Just a robotic insistence to follow a claims procedure that severely inconveniences customers. All tyres perish eventually, but not usually after only 2 years and 6,000 miles of normal UK use - and not usually in the valley of the tread (which is dangerous, because it's closer to the structural carcas of the tyre). If my situation was a one off, you could just put it down to bad luck, but a quick internet search reveals plenty of other people with Avon tyres failing in exactly the same way. Bearing in mind that if you buy Avons and they perish like mine, you will be expected to jump through the hoops I have described above to make a warranty claim, the only logical advice I can give is that everyone avoids buying Avon tyres in the first place. FOOTNOTE - in terms of performance, I thought that the ZX7s were quieter than the Continentals that came with the car, but inferior in every other way, particularly economy. Anyway, what does performance matter, if a tyre perishes after only 2 years and 6,000 miles of use?
22.06.2019fromSpeegles
This is the 3rd set of ZX7s on my Rav4. I'm getting 35000km off each set, and they are nothing short of fantastic. My partner also has them in her B class Mercedes, again, excellent

Surprising amount of wheelspin from standstill in wet for 4wd suv. Also feels like the side walls are floppy on full lock However we have not driven the car with other tyres so nothing to compare against.

Have been very pleasantly surprised as to haw good the Tristar Tyers have been I drive a mix of roads Motorway A road and country roads and the tyers have proformed very well in the dry and also in the wet.

The car was supplied to me with brand new Triangle tyres - a brand I had not heard of and was not one I would have gone for but in the year that I have had them on the car, I have no complaint about their performance. I cannot say whether they would be the tyre of choice when replacement is necessary. t
