Is this to much or is it acceptable?

Hi Mike (thanks again). I'm running a spool. I haven't put those tires on the rims yet. But wear hole wise they have more rubber than any of my other 20" M/T's .Saturday I tested a pair of tires with plugs in them (and they held air after the run), and a set of 22" M/T tires.
The tires that are different circumference are the new 8 x 20 x 13" tires that are made for asphalt racing.
I'm going to try the inflate and leave in the sun method starting tomorrow. Because the tires are for oval track racing they purposely gave me different sizes. If I can't fix them myself I'll see if they can send me another pair that match.
Going down the track the car was pulling hard to the right. I thought it was torque steer made worse by the wheels sticking out 3" more than the others. Due to the wrong backspacing.
