Hey guys, I have 2 vintage Kyosho buggies and I was trying to source a wheel option and I bought the Schumacher U6760 set https://www.ebay.com/itm/NOT-HEX-TYPE-Schumacher-2wd-Front-Wheels-Tyres-U6760-Cut-Stagger-Slim-Yellow-/392781539288. I figured worst case I can just use the tires on a set of 2.2 inch rims but I really wanted to use the wheels if possible.

Does anyone know what size bearings these wheels take? My Kyosho cars use 4x8x3 bearings and I was hoping I might be able to find a 4x?x3 to fit my Kyosho cars?

Any help is greatly appreciated! Thanks!

I think that they used a 3/8" OD bearing, which is ~9.5mm.

Depending on the wheels, you "might" be able to open them up to 10mm. I don't know about bearing availability.

Or you might can try a piece of 3/8 to 5/16 shim bushing material. 8mm and 5/16 are nearly identical.
