Hello I recently obtained a dune buggy and want to replace to the rear wheels (just with the original plastic ones, the ones on it are wore out). So I searched the part number J5248 and find out there are two types of rear wheel, older ones and newer ones. The older ones are round and the newer ones are flat. I have the older ones. So they arrived today and despite having the same part number, they’re like a full inch wider and definitely taller. Like, I might be able to use some longer screws (the rim is split) but then I’d assume the axle will be too short. Anyone know what I should do? Find new rims or look for the “right” tires?
