Wheelbase Alloys Latest Reviews
Let everyone know how easy it was to buy our alloy wheels
We pride ourselves on excellent customer service and product knowledge, and thankfully our customers agree. If you have recently purchased a set of new alloy wheels from Wheelbase, please leave a review or email us your feedback.
I fitted a wide body kit on my CLS63, which meant it was not just a make of car and choose a wheel. If it was not for Stephens time at the Oldham branch, knowledge and product skills in specking the offset, it would have been a nightmare. Needless to say, the alloys are stunning, in the colour I wanted, and fitted perfectly with wide arches. Thank You, the car looks stunning.

Well pleased with my wheels, worth waiting for, great communications , third set I have purchased from you and probably be purchasing another set in the very near future and that is the best recommendation I can give you. Thanks. Gareth James P.S I might even get chance to fit them if it ever stops raining down here!

Great company and very easy to deal with and communicate with I picked the wheel and tyre package I wanted and chose the 6 months interest free option which again was really easy to apply for and sort out and they then messaged me back to advise that my could would require tyre sensors so they sorted that out too 👍🏻 3 days later I had the wheels and tyres balanced and fitted with the tyre sensors delivered to my home which I then fitted the following day and couldn’t be any happier with how they look on the car

⭐⭐⭐⭐⭐ Great experience! The alloys fit perfectly, look amazing, and were well balanced. One nut was missing from the original pack, but after contacting them they responded quickly and sent out two replacement nuts by next-day delivery, which was excellent customer service.

Brilliant service after I was very badly let down by a competitor. They were able to identify to me alloys and winter tyres for my vehicle that were actually in stock and get them to my garage for fitting within 2 days. Communication throughout was flawless. Not only that, the price was the same for better tyres due to a stock special offer: Continentals for the price of Toyos. Delivery was safe, secure and my garage was very impressed. The wheels themselves (I opted for Fox Racing F9s which also had a healthy stock discount) look great on my car. Don’t consider going with anyone else.
