Your good for stabilitrac they are off by a little more than a 1/4 inch. which is ok.
I'm not sure on how its gonna look though.
Its easy to figure out sizes that are not listed use the formulas below.
width x aspect % = sidewall height
multiply this times 2 then divide by 25.4 this will give you the total sidewall height in inches.
now add your wheel size to get the toatal height.
A 255/35 R20 tire would be
255 x 35% = 89.25mm (or 255 x 0.35)
89.25mm x 2 =178.5mm now divided by 25.4 is 7.03 inches.
7.03" + 20" wheel is 27.03" total height.
