Designed for cars, rather than vans, 4x4s or commercial vehicles.
A stronger sidewall lets this tyre carry more weight than a standard tyre of the same size. Marked XL on the sidewall.
Built to handle both summer and winter conditions, so the same tyres can stay on all year instead of being swapped twice.
245/40 R21 is a large premium and electric vehicle tyre size. The first number tells us that 245 is the width in millimetres. The second is the aspect ratio, so the sidewall is 40% of 245mm (or 98mm). The R means it is a radial tyre and the 21 means it is 21 inches. The overall diameter of the tyre is 729mm. It is an ultra-low profile tyre which helps with lateral rigidity and reduces sidewall flex during cornering. We offer the standard and the extra load (XL) versions of 245/40 R21 at Tyres.co.uk.
We take care of everything for you with our fully fitted prices:
You pay online for the tyres and the fitting, so when you come for your appointment, there are no extra charges for the tyre fitting.
The price shown for mail-order tyres covers the tyre only (including VAT). Once you’ve selected your tyres and proceed to the basket, a delivery fee will be added to your order. Please be aware that certain areas of the country may incur additional delivery charges and, in some cases, slightly longer delivery times.
