G31 - optimum tyre size
Discussion
After experimenting with multiple tyre and wheel combinations over several years for my 530d x drive:
- 20 inch run flats: totally awful on every count and multiple cracked wheels and blow outs and SLOW as I’d tiptoe everywhere
- 18 inch staggered non RF all season (275 40 18 / 245 45 18) - totally brilliant and supple but I wasn’t happy with slight ‘undersized) 18 inch look
I’ve now gone for 19 inch non run flat CrossClimate 3 with an increase in profile to 275 40 19 / 245 45 19 which seem a little more harsh than the 18s even though the profile is the same - but I guess this is the CrossClimate 3s are more ‘sporty’. Wondering whether anyone else has gone up a profile over OEM and or what others optimum G31 tyres are. Pic on 19s with CC 3’s:

Appreciate this is off topic, but does VDC mitigate the hard ride? I'd go 19s with VDC for best combination of "look" and ride comfort.
In the absence of VDC I think you have arrived at your best compromise. 20" is too hard riding, 18" you aren't happy with the look of the car, so 19" it must be. CCs seem an excellent choice.
Silly question - does the speedo read correctly if you change wheel size but keep the same profile tyres? I thought the circumference would need to be the same to avoid the speedo over or under reading?
