It is more than likely that you need a new strut
Probably worn steering and/or suspension parts. Have the front end safety inspected.
It depends on how you hit the curb. If you rub the outside of your tire while it is still rolling, it will ball the tire. If you hit it square on the front of the tire going 10 miles per hour, it will not hurt the tire.
If a component was replaced If you see uneven tire wear . If you hit a big hole with the front tire ,once a year anyway.
Not without a lift kit. It will damage the tire and frame everytime you hit a bump.
so long as it will not interfer with your finders big as you want. I put big ones on mine for better mpg and if I hit the right bump in a turn the front tires hit a little and the speedo is off by 5 mph. but I get better mpg.
Upper ball joints need replaced
possibly your front upper control arm bushing are out.
I have ran 275/60/15 on ours all the way around. Front would rub if you hit a hard bump while turning to the fullest extent. I favored the 255/60/15 the best.
If your front-end is loose after hitting a bump, but not at speed, when you use the brakes, or when you turn - then the most likely cause is going to be your suspension.
you need to check shock absorbers and wheel bearings. also check all the front end components such as bushings, one or more is worn out and needs replacing
yes any one can hit the ball over
