These are great for helping hold the glued tyre firmly onto the rim They fit 85mm rim and I use them myself to glue my 1/8 nitro and electric buggy tyres and my short course tyres. Have used the aka ones but find these are better because they have the tags around the sides to get a better grip to reposition bands if needed. Come in a packet of 4 tyre bands and all yellow
