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.

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.

Iain Reid
Written: 23rd April 2025

Excellent service - I decided to upgrade my Discovery 4 Landmark from 20" wheels to 19" wheels as the tyres I needed were not available in 20", but were in 19". I got a set of 5 wheels and they are excellent. Wheelbase were very helpful and supplied a set of wheelnuts with the wheels as the wheel holes for the nuts were 30mm (the Land Rover wheels are 35mm). they even supplied a set of locking nuts as the originals were too wide - the bonus - the locking nuts look just like the normal nuts once fitted - looks nice. The only downside is that the wheels do not fit the spare wheel carrier - as my D4 is the last of the line, it is Euro 6 with AdBlue and the wheel has to be fitted nice side down - the carrier has three studs to fit the Land Rover wheels, so I will have to have these cut down to about 4cm to fit the new wheels - this way the wheel will fut and the shorther studs should hold the wheel without having to enter the smaller hole. Excellent service all round from Wheelbase and everyone I spoke to was very helpful. I just wish they had mentioned that the holes were narrower than Land Rover standard as they were recommended for a Discovery (though it's only the AdBlue version that has this problem) - and they do look excellent on the vehicle - very happy.
