I have used their services twice in the last nine years. On both occasions, I experienced nothing short of totally professional service. Recently, I encountered a problem with wheel nuts and posed numerous questions via email to them. Russell, from wheel base, went above and beyond to provide thorough answers. They are generously sending me a complimentary set of wheel nuts. Seriously, who does that nowadays?

Ordered 4 wheels with tyres and TPMS sensors and they’ve just arrived and look fantastic. Order was slightly delayed but not due to the wheels, but rather sourcing the tyres I’d ordered. They are not a very common size and I’ve read other people having trouble sourcing this tyre size. Anyway, WheelBase fulfilled my order and delivered as promised. Excellent. Just proves it doesn’t pay to be impatient with a legitimate business and delays out with their control do happen, but they will do their best to meet the customer’s needs. Thank you WheelBase Norrie

Very pleased with my new wheels, had some issues with one damaged wheel but this was down to the currier company not WB. That said wheelbase ordered a replacement promptly so I can not fault the excellent customer service I received. I don't normally write reviews but this was really worth it. The whole team was great from the start, sales to customer service. Definitely recommend and I don't normally hand them out. Thanks

I bought a set of four 8.5x20 Calibre Spartan (Gloss Black Polished) wheels with tyres from Wheelbase Alloys in September 2025 for my Range Rover Sport. I needed to move to a slightly smaller wheel size due to weekly trips up an off-road track, as the larger original wheels were starting to get damaged. The team at Wheelbase Alloys were really helpful in talking through the options and recommending a wheel and tyre package that would work well for the vehicle. The fitting service was first class, everything was done professionally and efficiently, and the wheels look great on the car. Very happy with the whole experience and would happily recommend Wheelbase Alloys.

Absolutely fantastic service. No queuing on the phone, and all the staff were on the ball and extremely helpful. I needed to source a set of alloys urgently after damaging mine in a pothole. They quickly found the correct size, style, and all the necessary extras, and the wheels arrived securely packaged the very next day. Very reasonably priced as well. I would definitely recommend them and wouldn’t hesitate to use them again.
