Yes, before we dispatch your wheels, we will ensure the offset, bolt pattern and rim width are fully compatible for your vehicle.
Don\'t worry, the reason for this is that the image is provided by the manufacturer, and they very rarely provide one of each amount of stud holes. We promise that we will supply the wheels to you with the correct amount of stud holes for your vehicle, fully fitment checked and supplied with a free \"brand new\" compatible fitting kit.
Yes, most people who buy alloy wheels and tyres do this. We will ensure that your new wheels and tyres are the same overall rolling radius as your current wheels and tyres, so that your handling and speedometer will not be affected.
No, we highly recommend that you use the free fitting kit that we supply. This way we know that they are 100% compatible with your new wheels. The ones that we supply will be brand new, so they will look great with your brand new wheels.
Yes, for an additional £10.00 we can supply a locking wheel nut/bolt for each wheel. When you add your wheels to cart, you will be presented with a pop up where you can add additional accessories to your order, including locking wheel bolts.

In the large majority of cases, yes. We check our tyre size data against several leading providers to ensure that we display the correct size for your vehicle. If you would like to change the tyre size at all, you can do this by selecting a new tyre size to the left of the wheels & tyre packages.
Yes we do. We highly recommend winter tyres as they provide far superior grip in temperatures below 7C. To find winter tyres all you need to do is click on the Wheel & Tyres Packages tab and scroll through the tyres until you see the blue winter packages.
Yes, we can ship anywhere in the world. You can find out more deliver information about your country by selecting the delivery tab.
