Yes - as long as the tyres on the same axle have the same tread pattern.
You cannot rotate tires on a vehicle when the rear tires are wider than the front. They must stay where they are,
for traction
To provide more traction.
if you have ever spun out without moving then it would wear the rear tires more than the front.
Only on a front wheel drive vehicle. On a rear wheel drive the rear tires wear faster. rotate your tires every 10,000 miles and they will wear evenly.
If the truck is backing up with the front tires turned, the rear of the trailer will swing in the opposite direction of the front tires. For example, if the front tires are turned to the right, the rear of the trailer will swing to the left. This pivoting effect occurs because the trailer follows a different path than the truck's front end. Proper alignment and steering adjustments are crucial to control the trailer's movement while backing up.
By ratio if you mean size, the answer is no unless the car comes from the factory with a different size rear tires than front tires like some sports cars. In that case you would have 2 tires the same size on the front and 2 tires another size on the rear. You should never ever run 2 different size tires on the same axle. Therefore you would never have a situation where you would have 3 tires one size and then 1 tire another size.
Why? To even out tire wear. The front tires will wear much quicker than the rears on a FWD vehicle. The front tires are pulling the vehicle and are also steering the vehicle. This causes friction which causes wear. You rotate by simply putting the rear tires on the front and the front tires on the rear every 10,000 miles. Click the link and go to Tire Rotation.
yes. both front must be exactly the same though and the same goes for the rear pair.
your car needs a wheel alignment, could be to much toe in or toe out. which means your front tires are angled slightly different directions. i would recommend a balance and rotate aswell as your front tires could be more worn than the rear.
You can if the suspension has been designed to run that way. You cannot just put smaller tires on the front of a regular car and expect it to handle well, it will give problems
will it depends, if you have more than 5 girls/guys in the trunk, then no, cause it out wights theengine and makes the car have lean on the back, making the front tires wear-out slower than the rear, but also you have toconsiderif its 4x4 or front-drive or rear-drive, if front-drive then yes it wears faster, and if rear-drive no slower,that'sspeaking if u have exactly 5 girls/guys in the trunk.
