Tamiya Stratos PU tyre set.
 
These tyres come as a set of 4 and are cast directly from the original Tamiya tyres, so look exactly the same, but they are made from 40 shore PU rubber. They are a direct fitment onto the Tamyia kit wheels and will give FAR better grip if you decide to convert your 1/24 Stratos into a slot car like I did in my video.
