Once tires have been mounted, we are unable to take them back even if there is a fitment problem. Tires with mileage on them cannot be returned. For package purchases, you are responsible for test fitting before driving on any products. Once wheels/tires have been mounted on the vehicle we are not able to accept a return. If you have any concerns about fitment, simply share those concerns via email, before you place your order, and our experts will work with you to get a perfect fit! Due to the fact we move quickly, it is important to notify us immediately if you have concerns. All suspension/accessory items being returned that are not warranty related CANNOT have been installed or attempted to be installed. If we receive a return that shows signs of installation, we will not be able to accept the item and will have to return to sender with no credit being issued. With our massive online gallery of installed wheels/tires on vehicles we have empowered our customers to make the proper fitment decisions. You will see many of our customers go beyond the “conservative” fitment offered by manufacturers and “guaranteed” by our competitors. They are doing this by making modifications and trimming plastic and sometimes metal to make the wheel/tire combo fit.
Curve & Curve L are a high quality, ergonomic push rim designed and made in Germany. These are available in two sizes: ‘Curve L’ for a larger hand, or ‘Curve’ for smaller hands. Designed for wheelchair users with complete hand function.

For me, base on this design, as long as you can maintain the hub to be: ground to hub distance would always be greater than the hub to the horizontal distance (radius) to the rim. then you should be fine.
It’s important to note, that the axle is slightly wider than the tail of the frame. I widened the opening by grinding down just enough metal at the tail work a rotary tool to gain clearance. After that, it took no time to install. As an aside, this presents a perfect opportunity to change your brake pads as well. I was extremely hesitant to buy one of these wheel assembly kits. Many had reviews of non-spinning wheels or other horror stories, but this one did not. I took the jump, and it has worked out perfectly. No more back flats to worry about, and no loss to top speed! The ride is a little bumpier, but i only noticed the first ride or two. Slight decrease to total range as well, but that’ll happen. It fit my M365 perfectly, just had to adjust the brakes to fit this setup. I can not recommend this enough as a quick solution to eliminate flat tires as an issue. I am beyond pleased with my purchase
