This is the TDR Flame tread tire and rim cylinder package.
The size of this tire is 1.1" Wide by 3.0" Tall tire and 2" rim. This corresponds to a tire specification of P235-45-16 in 1:1 scale.
These dimensions, though very close should be considered approximate, some round off error should be expected.
