235 45 R18 Tyres
235 45 R18 tyres are a hugely popular fitment, and in our experience they turn up on everything from sporty coupes to family crossovers and electric cars. You will find this size on the Lexus RC, the Hyundai Kona, the Vauxhall Zafira and the Tesla Model 3, among many others. Our fitters stock them from premium names such as Michelin and Pirelli, through to sensible mid-range and budget options to suit your car and your budget.
The size is quick to read once you know the code: 235/45/18 means a 235mm width, a sidewall that is 45% of that width (around 106mm), and a radial (R) construction built for an 18-inch rim. On higher-performance cars you may see it written as 235/45 ZR 18, where the Z points to a higher speed rating. If you want to check what the numbers and letters on your sidewall mean, our tyre label information guide breaks it down.

How to check if your car has 235 45 R18 tyres
The size of a tyre is printed onto its sidewall and is defined by three numbers. The first gives the width of the tyre expressed in millimetres, which is followed by the height of the tyre sidewall which is defined as a percentage of the width. The third number is the rim size in inches that the tyre fits, preceded by the tyre designation letter, which defines the tyre construction but does not relate to its size. Additional information includes other aspects such as the load index and speed rating.
It is well worth checking your tread and pressures as often as you check anything else on the car, because both have a direct effect on grip, braking and running costs. If you are not sure whether your current set still has enough life left, our team can measure your tread and talk you through your options with no obligation. Book a free tyre check and we will tell you honestly whether you need new tyres yet.
Choosing the right 235 45 R18 tyre for your budget
Prices for this size vary depending on whether you go for a budget, mid-range or premium brand. Budget tyres keep the up-front cost down, mid-range options balance value with longer life and grip, and premium tyres tend to deliver the shortest wet braking distances and the quietest, most refined drive. Whichever you choose, fitting is included in the price you see.

235/45 R18 Tyres Frequently Asked Questions
Whatever the season throws at you, this size has you covered. For most of the year, 235/45 R18 summer tyres use a harder compound that stays smooth and fuel-efficient on drier roads above roughly 5 to 7°C, while 235/45 R18 winter tyres switch to a softer compound and deeper tread that bite into snow, ice and cold wet surfaces once temperatures drop below that mark. If you would rather not swap twice a year, 235/45 R18 all season tyres sit in the middle and stay on the car all year round. We also stock 235/45 R18 run flat tyres, which support the car's weight after a puncture so you can drive on a short distance to safety before replacing the tyre.
