I am going to buy two new tires. Should I put them at the front or at the end? I know replacing all four is better, but cant do it right now.
please give me some idea.

 

The new tires or tires with the best tread always go on the rears.

This has been discussed many times before.

Search for the answer.

The answer is based on the ability of the tires to maintain traction in the wet and avoid hydroplaning (prevents loss of traction and control).

Good tires on the front will resist hydroplaning in the wet and the bad tires in the rear will risk loosing traction.

Good tires on the rear will follow better and resist loss of traction, while the less good tires on the front will usually do OK being on the front where you can use steering and throttle to maintain control.

 

Did you rotate your old tires on a regular shcedule? If so, they should be fairly evenly worn all-around. Unless it's not possible, four new tires are a much better (and safer) bet, and regular rotation will get the most miles out of the next set.

 

That is correct on the rear. Check out michelin.com web site for all the details

 

Cliff's notes: Would you rather spin off the road or push the front end off the road? If you chose option 1, then put the better tires on the rear.

Let's see....You steer with the front, get most the braking from the front, in front wheel drive you get your power to the ground from the front and if I'm going to have a blowout I'd rather have it at the rear where it's easier to control. I'm going with the front. Just my 2 cents. PS: But I always get four tires at the same time.

 

Then you're going against the advice of every tire manufacturer in the world...

 

You are right that 4 tires is best. It preserves the original balance of the car.

While I understand your logic, but there is a reason why we do need to put 2 new tires in the rear. Generally, it is much easier for a street driver to control and correct for understeer or push (if you mount two new tires in the rear) than oversteer (if you put the two new tires in the front). All tire manufacturers recommend that you put the two new tires in the rear for safety reasons. This is true regardless of the drive tires (rwd or fwd or awd).

 

This is really dangerous logic that I've seen almost hurt a few friends.

With no rear traction you will spin in wet conditions with even just lifting off the throttle going into (or worse, in) a turn. I've seen it. It boggled my mind because I thought the same way you did. You can also spin by lifting off the brakes in such a situation (learned this the hard way on the track).

So to summarize your thinking you would rather:
- accelerate
- steer (which is exactly what leads to a spin - the front tires grip and the rears don't)
- avoid a front blowout

Fair enough, but those rewards don't outweigh the risks in my opinion.

If you go by every major car manufacturer in the world, you would want to push off the road being the reason they all put such an abundance of understeer in their cars to begin with. Rear.

 

Correct and it does happen in wet or dry especially in a turn. Trailing brake or trottle oversteer (TBO and TTO) happens when you unbalance the car and shift weight too quickly to the front. That is why you need the new tires in the rear for better grip when it is needed unexpectedly. Newtonian physics works well in this case, but can be a little counter intuitive. Oversteer is difficult to correct unless you anticipate it. TTO and TBO also can be your good friend if you can control it well.

Hope we have more street drivers putting their new tires in the rear of the car. It is just safer.

 

hmm.. this is interesting. every tire shop i've ever been to has put the new tires on the front.

 

Ask them why they are doing that. It would interesting to get their perspective.

FYI, my tire shop puts it in the rear.

Glad we agree that not only is understeer safer, but so is putting better tires on the rear so as to induce understeer as opposed to its nasty sister, oversteer.

Or is that every tire manufacturer in the world's legal department. Always thinking of us first, I'm sure.

New tires on the rears.

Even with one new tire- on the rear.

Or replace tires in pairs would be better than just one.
