255-35-20 is 27" tall
295-35-20 is 28.1" tall
yeah that will give stabilitrac issues.

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.

245/45 really isn't quite enough tire for 9.5" wide rims - I think something more like 265/40 might be a better overall match for the 9.5" wheel width and your 305/35 rear tire size.
