155 70 R13 Tyres
The 155 70 R13 tyre size is one of the narrowest fitments we still stock, and in our experience it means a light city car or an older supermini.
155 70 R13 tyres measure 155mm across the tread, with a 70 per cent aspect ratio that puts the sidewall at 108.5mm, radial construction and a 13-inch rim. Cars we see with this filament is primarily ones like the Citroen Saxo.
The safest way to identify the correct tyre specifications for your vehicle is from your user manual or at your local Protyre garage. However, you can also check the specifications on the sides of your current tyres.

Reading the code on a 155 70 13 tyre
A tyre code resembling 155 70R13 is telling you your tyres are 155mm wide, have a 70-aspect ratio (the sidewall's depth as a proportion of its width expressed as a percentage) and are for 13" rims. The "R" indicates they have a radial tread pattern and construction.
Although these factors tell you the physical size of a tyre, they are not the only aspects that matter. Tyres are also rated according to the weight they will carry and the maximum speed they can be safely driven at. Usually, these qualities are denoted by some additional code letters.
For example, a 155 70R13 82S should never carry a load of more than 475kg or be allowed to reach 112mph. Online tables are available to explain these code letters, or if it is easier, just ask one of us at any Protyre garage.
The rating your car actually needs is on the plate inside the driver's door or in the handbook, and fitting below it can invalidate your insurance. On a light car the margin is usually generous, but it is worth checking rather than assuming, and our fitters will confirm it against your registration before anything goes on.
Comparing 155/70 R13 tyres before you buy
Choice in a 13-inch size is narrower than on a modern fitment, which makes the comparison simpler rather than harder. The tyre label grades fuel efficiency, wet grip and noise on a common scale, and on a tread this narrow the wet grip grade is the figure most worth weighing. Our help and advice section explains what each grade means in practice.
Age is the other thing to check on a car of this generation. Rubber hardens whether or not the car is driven, so a set with plenty of tread left can still be past its useful life. The four-digit code on the sidewall gives the week and year of manufacture, and our fitters will read it off for you.

Frequently Asked Questions
Two separate things. The 82 is the load index, which converts to a maximum of 475kg carried by that single tyre. The S is the speed rating, meaning the tyre is certified up to 112mph. You will never approach either figure in normal driving on a small car, which is the point: both are engineered headroom rather than targets. What matters is that the pair on your new tyres meets or exceeds what the vehicle handbook specifies.
Not without checking. Widening the tread changes the rolling circumference, which throws out the speedometer reading and can foul the arch or suspension on full lock. On a car designed around a narrow tyre, the light steering and low rolling resistance are part of how it was set up, so a wider tyre often makes it worse rather than better. Speak to our fitters before ordering and we will tell you what actually clears.
Keep the expectations realistic on a size this small: winter and run flat versions are not something we currently show in 155/70 R13, so check with your local garage before planning around either. The range is built on 155/70 R13 summer tyres, using a harder compound that runs smoothly and keeps fuel use low on dry and wet roads above roughly 5 to 7°C, and 155/70 R13 all season tyres, which trade a little of that efficiency for a softer compound and extra tread sipes that carry on working as the temperature falls, and stay on the car through the year.
