Possible combinatios tires for '20 front and rear.
I need your help.
I want to mount in front 9,5x20 with 295/40R20 and rear 10,5x20 with 315/35R20.Tehnical it is ok to mount diferent dimensions tires rear/front if the car is 4x4 permanent?
For summer i choice OZ LEONARDO III 9,5 with 10,5.
Now i have ATP MAGNUM INOX 255/55/18 winter tires.
If I remember correctly, the center diff can cope with 4% difference in tyre circumference.
315/35 has 2220mm circumference and 295/40 has 2269mm, so it shouldnt cause any problems. (if you wont mention radical down grade in every day drive-a-bility)
I had 275/45/19 and those were bad on worn road, now i have 265/40/20 in Porsche and those are equally bad when compared with my winter tyres which are 255/55/18 like yours. Its equal size with Caynne Turbo originals, and there is a reason why factory decided that size. Doesnt look sexy, but behaves so.....
