The new tires should be placed on the rear axle to lessen the risk of hydroplaning.
front tires straight back rear tires crossed to the front
move back tires to front and front tires to back
It should be the back
If you mean balance them, I say yes because you should balance and ROTATE the tires at the same time, thus making the front tires the back tires, and vise versa, Chuck
You have a damaged tire. Try rotating the front tires with the rear tires to see if the wobble switches to the back.
32 on front and 30 0n back
You put them wherever they are needed. If the threads are bare then they need replacing by law. See a car professional. If possible, put the best tires at the back. When braking(hard), the weight at the rear of the car will be momentarily reduced, making it easier for those wheels to break free and skid. By having the tires with the best grip at the rear you reduce that risk a little.
Tractors have small tires on the front to make it easier to steer the tractor. Large tires are harder to steer. The large tires in the back allow the tractor to have more power as it plows.
unless you have different rim/tire sizes at the front vs back (which you shouldn't) the pressure should be the same in all 4 tires.
I am no expert, but I would put only two new tires on my front wheel drive car, I always put the best pair in the front. I am not good with cars but 2 be honest i think you should put the 2 new tires on the back because the back wheels are the 1s that move the car and they need better mobility
tire rotation
always cross to the power. ie-front wheel drive. back tires cross to the front. and visa-versa for rear wheel drive. 4x4-cross in an x pattern.
