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.

Really nice tyre, giving a comfortable ride, also has good grip and responsive when driving more actively.
10.12.2018fromNick Skew
When I purchased the car in July 2017 it was fitted with Hankook tyres and they performed well. Previously I had a 2015 TT and for that I purchased a space saver wheel which I transferred to the TTS. I then discovered it wouldn't fit on the front wheels of the TTS because of the larger brake callipers. So I then had a dilemma as I don't trust the inflation kits supplied with the car. I therefore went for run flat tyres and the Goodyear F1 Eagles looked a good option (but not cheap!). When the tyres were delivered to Boxley tyres (excellent) they advised that they wouldn't have ordered run flats for a car like the TTS as they have stiffer side walls. However, to be honest, I haven't noticed any difference and I can drive with confidence that worst case I can carry on for 50 miles with a flat tyre and have the space saver if necessary which in the event of a rear puncture I can fit or in the case of a front puncture swap a rear wheel to the front. I have driven through some horrendous rain recently and the grip has been good. This car being quattro you don't slow down for puddles!

Steering and wet road handling improved since replacing the standard tyre fitment.
21.05.2019fromJane
I bought these as they rated well performing across the board. Not top in anything but above everything that was top in at least one area. The wet grip and braking is fantastic. Performed well throughout the cold months but we had no snow this year to test them. On warm dry roads the compound or pattern does not allow for an aggressive driving style but I never intended to keep them on in the summer so this was irrelevant to me. They make a noise like driving through standing water in the wet which is strange at first but I wouldn't say generally they were any noisier than my Eagle asymmetric 2 that they replaced. Did everything I expected from them and will be re fitting them come the winter.

Have tried lots of different snow tyres over years and put these on my 3 series touring to replace the Pirelli zero’s. If anything I thought they ran quieter than the zero’s and plenty of grip in both dry and wet conditions. Used the in snow as well and kept everything moving which is all you want from a snow tyre.
15.01.2026fromJames
As my Volvo is a rear wheel drive automatic I always use winter tyres. Previously had Goodyear ultra grip 9 and still have them on the front. New Goodyear ultra grip 3 on rear. We're great in the recent snow, where front wheel drives were getting stuck, no doubt on summer tyres.
11.01.2025fromAndy Duff
An extremely sure-footed winter tyre that blurs the transition from my summer to winter wheels. As good as it gets.

Noted an increase in millage from tje start, also noticed a noise reduction while driving. Good grip and reduced roll. All in all a good upgrade for electric cars.
10.06.2021fromAnthony Hibbs
I bought these tyres as they are the only ones on the market that claim to be specifically designed for electric vehicles and are carbon neutral in their manufacture. Lots of claims made by Michelin regarding low noise levels, grip, wear and increased range. I can confirm that the tyres live up to these claims in all respects. I have driven around 1200 miles in mixed road and weather conditions and have been very impressed. My eGolf was always a quiet car, but now it’s almost silent with little or no road noise below 50mph. Braking and handling in wet or dry, good roads or bad, is exceptional. My average range previously was around 150 miles from a full charge, now it’s 160 miles, remarkable. I absolutely recommend these tyres for electric vehicles.

This is the second set of the same tyres, and yes they hold the road well. When you have 20 something inch of rubber on the road they can really hold there own. The Which magazine holds Bridgestone to high esteem.
13.10.2020fromBowber
Great tyres, good grip especially in wet, feel safe! Noise isn’t too crazy, hopefully get some decent mileage out of them
11.07.2020fromPat
Much better in the wet than Dunlop tyres that were on the car.
24.03.2020fromSmiffy
OEM tyre for car. Provide amazing grip in a 4 wheel drive lightweight sports car. Cornering at speed is amazing, braking too.

17.11.2015fromviktor vari
excellent tyres for very reasonable price. definitely would buy them again
10.09.2015fromGES
Supposed to give excellent fuel efficiency. Getting poorer MPG that I did from my Continental Sports! Difficult to say but wear does not look too good on front, doubt I'll get another 12k out of them!
09.09.2015fromJoseph Kinney
Starting to lose some of that high end grip when pushing hard but a very good tyre, great performance and very predictable.
02.07.2015fromSaulius
Very good tyre, but wears very quickly. But again, if you want solid grip in wet, the compound has to be soft and it means it will wear quicker than others. Had p-zero previously, was a bit noisy, dunlop makes much less noise.

Excellent in the wet, no hydroplaning or wheeljerk when driving into puddles at speed. This is my second set of this tyre for this reason.

I'm sorry to say that the tires don't hold up. They always tend to slip.

- I fitted the new Bridgestone Potenza Sport tyres mid April and with very low mileage on the road and less than 100 miles on track the tyres are done and worn out.. - fabrics showing…?! I did many track days previously with the S001 RFTs with no issues- Potenza Sport is simply not a tyre for track use - even for a lap or two…

I had no issues with the tyres, which replaced previous Bridgestones.
