Concur with you that there is a problem.

Not sure whether your new saga stock OE tyres wear rating UTQG is low'ish below 350 or 300, I had been getting 110K-115K kms of tyre life consistently for the past decade from several pairs of XM2 (with wear rating of 420) replacement with a residual tread depth of 2.0-2.5 mm where 1.6 mm is the cut-off point for mandatory replacement.

If I may speculate the Saga's suspension alignment angles are most probably the culprit of relatively shorter tyre life in your case, never mind the fact that it is a new car.

Which axle tyre has the higher wear rate? Even or uneven?

Note:
The current pair of XM2 on my Avanza Front axle has been in use for 88K kms (of about 4.5 years duration) with a residual tread depth of 3.0-3.5 mm and ........ going.
Its rear pair was replaced some 3 weeks ago with serviceable residual tread depth to spare.
All 4 tyres were at its original corner respectively, and never rotated.

Did you readjust the wheel alignment angles on the saga?
