Frequently Asked Questions

18" Brock B21 Crystal Silver Alloy Wheels

Wheelbase is the UKs leading alloy wheels and tyre store. Over the years our customers have asked a variety of questions which we have answered below to help you understand a little more about Wheelbase and our alloy wheels and tyres website. If you need any further help or assistance please contact our team.

Our phone lines are open: 9am to 6pm (Monday - Friday) and 9am to 4pm (Saturday).

Are these alloy wheels in stock?

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.

Will the wheels be supplied in the correct fitment?

Yes, before we dispatch your wheels, we will ensure the offset, bolt pattern and rim width are fully compatible for your vehicle.

The alloy wheel picture displays the wrong amount of stud holes for my 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.

Is it ok fit different size wheels & tyres than standard?

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.

Will I need to use my current nuts/bolts with the new wheels?

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.

Do you sell locking wheel nuts/bolts for these wheels?

Yes, for an additional Â£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.

Do you sell any other tyres than what is listed on your site?

If I buy a wheel and tyre package, are they fully fitted, inflated and balanced?

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.

Is the tyre size shown on your site correct for my vehicle?

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.

Do you sell Winter tyres?

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.
