Yes, these alloy wheels are in stock. We offer fast dispatch times with a fast delivery service to make sure you receive your wheels as soon as possible.
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.

Yes, all packages are supplied fully fitted, inflated and balanced. All you need to do upon receiving them is bolt them straight on the vehicle with the fitting kit supplied. You could do this yourself or take them round to your local garage and have them fitted for a small charge.
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.

I've used Wheelbase a couple of times now to take advantage of the interest free option. Wheels always come really well packaged and they arrive in a few days after ordering. I like that they use DPD as their courier as they are really dependable and friendly when delivering. You get text messages and emails telling you about every stage they are at getting the order ready so you know exactly when they will arrive. I had a small issue with something missing from the order but a quick call and the items were delivered next day. Can't fault the quality or service 5*

Aaron was absolutely brilliant! I had an issue with my wheels that thy were vibrating the whole car when I got to around 65. I called up and they put Aaron on the phone and he was very helpful he sent me boxes to package the wheels back up as I got rid of the boxes after I put the wheels on the vehicle. And they arranged collection of the wheels and investigated the issue and put all new tyres on the wheels (even upgraded ones at no extra cost to me) and sent the wheels back to me quickly! Absolutely great service from Aaron!
