None on an automobile.
you can put mud tires both on the rear and front of the car, if the size is proper and it meant to be there.
2WD: on the front tires 4WD: on the front and rear tires but Honda Pilot 4WD is not a full 4WD therefore no need to put chains in rear tires unless you're manual engage 4WD.
On the front tires.
On the front tires.
Can be that they're simply worn out. Particularly if it's a rear drive car, then accelerating hard will put a lot of wear on the rear tires.
No But It can be done and will increase traction
if you put sticky tires on the back with that rear end it won't last, personally I would go with a 83/4".
Make sure you don't switch tires from one side to the other. Take the front tires and put them on the rear, and the rear tires will go on the front. Make sure they stay on the same sides that there on. That's it.
The main purpose for Dual rear tires is for 2 basic reasons. 1. When towing a heavy load, it lessens the chance of over stressing the rear tires (In extreme cases, the blowout of the rear tires) 2. It provides more traction in all situations (by having more rubber on the road, the torque put out by the engine is displaced in more surface area than single rear tires) I'm sure a true expert can put it into better words, but there's a basic answer.
The powered tires. On a front wheel drive car, the front wheels. On rear wheel drive, the rear wheels.
The chains go on the Rear tires. For the rear wheel drive cars.
Did it shake before you had the tires put on? It sounds like your tires are out of balance. I had new tires put on and had to go back next day because of shaking at 60 mph. Come to find out the tire balancing was off.
