Autocross
hello everyone have a question I want to autocross my car more but it has 20' rims on it and the front tires are 30 series so there isn't much side wall on them if I were to get another spare and mount up two real tires onto the one I have and the one I might get would that be better I know it wouldn't be as good as buying track wheels and tires but I'm trying to get results cheaply and what size tires could I go with my rear tires are 285/30/20 thanks everyone

my 20 inch rims it's 245/30 what size could I squeeze onto spare 18' rims that would be close to same outside diameter of my rear wheels?

A 245/45/18 would be very similar in diameter to that 285/30/20
