Problem with Vehicle Tire Size

Hey there folks,

i am looking for some help, creating a racing game. im quite at the begining learing the unreal engine but my first vehicle does work quite well …
my plan is to add some customization options, changing parts, changing colors etc. but i am stuck at the wheel setup.

i did create the tire blueprint, tire type setting, collision, well everything that is needed. my problem is:

is there a solution to pick another wheel setup while ingame from stock to racing tires or from 195/50R16 to 245/30R19 for example with cast to vehicle blueprint? or do i only use one tire blueprint but i cant find a way to change shapes radius

or do i need to switch over to c++?

has anyone an idea?
