Tire size recommendation

Hello, a friend just gave me a set of staggered 19'' wheels (19x8.5 & 19x9.5). What would be the appropriate tire sizes for my 428i xdrive gran coupe? Thank you

My wheels will be the same size and I'm looking at 235/35-19 and 265/30-19 or maybe 245/35-19 and 275/30-19.

Those are the options. I went 245 front 275 rear. Either will work fine assuming the offsets are within reason

The offset is +35 all around.

245/35/19, 275/30/19 (25.8/25.5) diameter difference is too much.

245/40/19, 275/35/19 (26.7/26.6) is okay but tire diameter is .6 greater than oem size

235/40/19, 265/35/19 (26.4/26.3) closest to oem diameter while maintaining less than 1% diameter difference. 235 is slight stretch on 8.5 and 265 is optimum size for 9.5" wide. tires slightly taller than oem fills the fenderwell gap

235/40 and 265/35 is an ideal set up imo.
