After years of my Mercedes AMG alloys cracking at the slightest sight of a pothole, and extended periods off of the road whilst getting them repaired, I decided to just go for new wheels. I opted for the wheel and tyre package. Even though the same size as was on the car didn't seem to appear, after contacting customer services, they sorted it out quickly. On arrival, the standard wheel bolts in the fitting kit were too long, but with a couple of photos, and a quick email chat with customer services again, that was resolved within a day. All in all, I couldn't be happier. It looks far less likely that the rims will crack, and I don't know if it is the new rims, the new Tyres (not a brand I'd tried before), or maybe both. But the ride is smoother, and even when you miss potholes and travel over those patched road repairs, there's no clunking or jarring that there was before. Very pleased I swapped out the originals!

Dave and all of the other staff at Wheelbase were great and very helpful with regards to wheel selection and tyre options… There was a delay to my order that was not flagged to me, however Dave and the team did all they could to turn this around asaap. Having no fitted the wheels, they were definitely the right ones to select and the right place to go with some fantastic options and all with the ability to finance the package…… would definitely use again. 😁

This is the second time I’ve ordered from Wheelbase and once again the service has been excellent. Customer service is spot on — helpful, knowledgeable, and easy to deal with. I found the wheels and tyres I wanted on their website, then gave them a call for some advice before ordering. The guidance I received was clear and professional. Communication was great throughout, with regular delivery updates. Highly recommended.
