Two new tyres on front or back

there is a correct answerbut some people prefer the alternatives, just because you fitted them to the front doesn't make it technically correct.

Well said its more the other drivers you have to worry about. Like running red lights and not giving way.

SO just what are your qualifications on this topic!

There's plenty of study gone into this and I'm sure the credentials of those who's names are on those studies are available.

As above, it's not just NZTA advising new on the rear, some tyre manufacturers do to, along with crash analysis teams, car manufacturers.a long list.

I actually don't think there is a correct answer to this that will fit every scenario, because all cars are different, and the muppets behind the wheel all drive differently.

But to suggest that you know better than those that do this for a living, and that your answer is right for every situation is a prime display of the Dunning-Kruger effect. Mind you, this message board could be used as a case study for that.

smac read post #69 someone who works in the industry they fit tyres and you should know this as you drive 30k per year which realy isnt a lot by the way I did more than that in the weekend car

Ill find the correct answer. I will ask the wife. Her answer will be the correct one. No arguing or debate, case closed.

Make sure you report back, I won't sleep thinking I put my two new tyres on the wrong end!

if you are worried about oversteer from putting new tyres on the front of the car, don't you think you are outdriving the road conditions. i would always reccomend the best tyres go on the front. braking and steering are compromised with poor tyres.

supernova2, Jul 28, 5:53am
Best of both worlds - put on opposite corners then you should overcome both under and over as both axles totally stuffed up.Simple wasn't it!

jack47, Jul 29, 3:07am
Thanks for all the input guys. Plenty of it. I decided i would put the new tyres on the back (at least to start with)
My reasons:
1.Most in the industry recommend it.
2. Also the two worn tyres have at least 4mm of tread and adhesion would not be much less than a new one!!
3. If a tyre did lose grip it would be easier to recover from the FWs slipping.
4. It is also easy to change the congfiguration.
BTW my car is a Camry Sportivo and I drive at a modest speed.
Any input welcomed.
cheers.

you guys have all got this wrong.
The best method is one good tyre on the front and one good tyre on the rear.This way you have a safe tyre on the front and the rear.
I thought you guys would have had enough sense to know this.
And you guys think you know about cars. pffttt!

Yes but with airbags on modern vehicle the piit manoeuvreis is rarely exercised now days.

sr2, Jul 29, 5:45am
And your point is.!

friendly_prawn, Jul 29, 5:46am
I would have bet you were going to come back with "and whats that got to do with the price of bananas"

johnf_456, Jul 29, 5:53am
Just making a comment about it not been used nowadays.

Problem!

mugenb20b, Jul 29, 5:59am
It is, but only in USA. The pit maneuver has not been used in Europe or Australia. Not sure about South America or Asia.

sr2, Jul 29, 6:01am
LOL, you're just faster off the the mark than I am F-P.

mugenb20b, Jul 29, 6:01am
Some cars, like a lot of US made (older) 4WDs airbags have a switch so you can turn them off. I'm guessing cop cars might have the same feature!

johnf_456, Jul 29, 6:03am
Yeah, but not sure about NZ law with how fussy OSH are in the work place. As a police car is considered the work place.

mugenb20b, Jul 29, 6:06am
Which is why I would put new tyres on the back of the car.

johnf_456, Jul 29, 6:08am
Or ideally rotate all tyres regularly and change 4 at a time. That way you also get same brand and type on all 4, has trying to find a model tyre you got a year or 2 ago can be a mission sometimes.

After all every wheel has its important role in car safety.

splinter67, Jul 29, 2:49pm
well said I laugh at some of the advice givin on here

sr2 have you ever had a blow out I would rather have steering that I can control the car with than NO steeering and lots of traction

richardmayes, Jul 29, 3:05pm
I had a right front tyre blow out (on a RWD car) on an 80km/h straight bit of road. the immediate loss of steering was a lot less than you suggest.

The steering felt a bit soggy, but that is all. It was no trouble at all staying in my lane as I drove off the bridge I was on when it blew, then decelerating (from 80km/h) around a big sweeping LH bend, and then turning off into a suitable flat patch by the side of the road.

This whole thread is pretty cringeworthy - if you "break traction" or "Step the back end out" on the public roads then the relative condition of your front & rear tyres isn't the real problem.

smac, Jul 29, 3:11pm
I did read it, and I think you've missed the main point of it. You've also missed the main point of my post. Listen more, talk less.

nightboss, Jul 29, 3:12pm
Another thing to consider with AWD and full-time 4WD cars regarding tyre wear and choice.
The transfer gearbox can be put under constant load when the tyres are of different circumference, different make or different pressures.
What ever you save on tyres can easily be blown should your transfer-box need overhaul.

splinter67, Jul 29, 3:22pm
Yes I agree with you on the last part of your post
The first bit you must be an awesome driver then I watched a car crash into the front of my truck because of a blowouton the front they didn't feel a steering wheel that was a bit soggy they lost control (well I'm not sure what they felt I couldn't ask them and neither could anyone else) I think you know why. Please remember that when you give advice about something as serious as this you are dealing with real world situations not computer simulations and peoples lives are on the line
