Sorry for my messed up link. I fixed it.

275/30/20 gives 761.17 revolutions/mile. I don't think that's going to be good enough. I don't know what the car will tolerate, but I don't think this is going to work.

275/25/20 is 793.6 revolutions/mile. That may work. Not sure about clearance, etc. You need to check that too.

Yes it will work. I've been running a 245/30-20F & 275/30-20r setup for the last 2.5 years with no issues. Only time my DSC freaks out is when I'm going sideways and I forget to turn the nannies off.

i have the same issue with my dsc abs lights it comes up wheel speed sensor supply but the only thing i can see is both front tyres are 245/35 20 but 1 has 90y and the other 95? and 1 the profile is less it looks like 1 is run flat and the other isnt 1 looks a higher profile is this what is throwing the faults?i havnt changed any tyres and this has only started happening since i changed my abs pump and module

The only thing that matters to your car's system is the diameter of the tires. If one is visually different than the other - even if they have the same "size" stamped on them, there's going to be a problem.

Also, keep in mind that two identical tires that have been driven different distances will have different diameters. 5mm more tread wear will result in a diameter difference of about 1.5% (well outside the suggested delta for side to side, or front to rear in an XI model's suggested max).

ok well that explains the issue im having then though there wasnt a issue when i first got the car its only since ive changed the abs pump and module🤔

It could just be coincidental. I know that when I've changed tires, it's taken my FTM system a while to flag an "error" (a change, which in these cases, was just new tires that differed from the old ones). At any rate, you just want to make sure that you don't have mis-matched tires left to right (or including front to rear on an XI model).
