i just got new rear tires that are 18x10x8. my original rear tire size was 21x10x8. do you guys think that big of change in tire size will make it to where the height of the swingarm is close to hitting the ground. because with the 21x10x8, its a good 5-6 inches from hitting. if it is close to hitting couldnt i just adjust something to make it to where it isnt close to hitting?
