Two new tyres on front or back

Yep, often 'felt" the help that a fully loaded & balanced trailer helped with cornering
Definitely a lot more to weight transfers then I mentioned but was hoping for a little bit of simplicity with std test rules.
Also as per std test rules, only 1 type /size(general spec) of tyre is allowed per set of tests for benchmarking.

I sort of get the impression that a lot of "opinions" are based on extreme events & fairly specific generalizations, &not on average daily driving situations.

Ppl should go have a blast on a fresh gravel road to see what under/over steer is really like.

Put them both on the drivers side. The cops always approach the drivers side of the vehicle first.

LOL. . . . . .Mmmmmm

Not so, you only have to watch the Suzuki Swift racing to see how many spin out from loss of rear traction.I actually saw one spin out in a straight line on a wet track.and they're front wheel drive!
Even more important with rear wheel drive. Had crappy tyres on the back of mine and the rear kept breaking away. Put the crappy ones on the front and good new ones on the back, all sweet!

It doesn't matter whether your car is FWD or RWD, under braking theweight is transferred to the front, increasing the front tyre down force, so you can brake hard and keep control without the front wheels locking up, so even crappy tyres will resist losing traction!

The opposite happens on the rear, it becomes lighter under braking with less tyre down force, resulting in easier wheel lock up and loss of traction, so you MUST have your best tyres on the rear gripping the road as long as possible to resist rear wheel traction loss!

Preventing traction loss under braking is a major safety consideration, that's why manufacturers fit bigger brakes on the front than the rear, along with ABS to balance the braking and maintain control for longer.

try driving a FWD car in the wet with bald front tyres. not good. No one should be going fast enough on the streets for the rear to step out going around a corner.

nzfatie, Jul 27, 7:07pm
I said crappy ones, not bald ones.lol
You're asking for trouble driving on bald tyres!

I rotate my car tyres/wheels at regular intervals and get 4 new tyres fitted each time because by the distance intervals I rotate my wheels at I get reasonably even wear on all 4 tyres.
I'm a fussy beggar you see and it pays off, by doing the tyre rotating thing regularly I get damn good mileage out of my tyres generally.
Wheel alignments I have done regularly too.
It is surprising just how much variation in alignment settings can be requiring a certain amount of adjustment or even on the other hand none at all.
It depends on various things encountered when driving as driving in general has extremes of conditions that aren't often taken into account.
Driving habits would be at or near the top of that list for sure.

It's to do with surviving a crash - on a car with frontal impact protection it's safer to crash head on than side on or go into a roll. Statistically there is better chance of surviving in a frontal than any other impact - so best tyres to the rear to prevent a spin. Tyre manufacturers, vehicle manufacturers and transport agencies like MOT, DOT and NZTA want the best tyres on the rear.

However, for me - I always put the best tyres on the drive axle as those tyres wear faster.

Where did you get your info from

unbeatabull, Jul 27, 8:48pm
We've been told similar by Tyre manufacturers and NZTA.

icemans1, Jul 27, 9:54pm
i would put new tyres on rear of RWD car or front on FWD car

chebry, Jul 27, 9:54pm
Best tyres on the rear wont prevent a spin what a stupid idea you prevent a spin by steering into a slide /spin which is why you need good tread on the steer. Dont you clowns know how to drive, even the drifters steer with front traction not rear traction open your eyes.

Put the new tyres on the passenger side because that side of the road is nearest the edge of the tar sealing and often has more pot holes etc. Also the camber of the road slopes towards the edge of the road and having more treat will help level out the car more.

splinter67, Jul 27, 10:14pm
and it looks good for the girls LOL

splinter67, Jul 27, 10:20pm
Who was it from NZTA they need to loose their job

unbeatabull, Jul 27, 10:53pm
I completely agree, and so does our work, we still fit new tyres to the front.

We also get recommended by our Manufacturer (We are a brand dealer), as well as tyre manufacturer's to fit to the rear when NEW. They do go on to say that they should be rotated to match tyre wear during the tyre's life.

I think that is something someone else touched on a while ago, but new tyres, that still have the shine or "Green" as some will call it on the tyre, with all the little knobbly bits etc, can have less grip then a tyre that has done a few k's.

And anyone in the trade would know NZTA/MTA/AA etc are all pretty out of touch with what actually happens in the industry :P

unbeatabull, Jul 27, 10:54pm
Just saying, Drifting isn't really driving! lol

And no, a vast majority of people on the road in New Zealand don't know how to drive, that's the problem! Already been over that in this thread! lol

splinter67, Jul 27, 10:58pm
Oh good I thought you had changed sides of the argument.You had me confused for a bit. Even had to reread your posts LOL

bellky, Jul 27, 11:56pm
Best tyres on front.

splinter67, Jul 27, 11:58pm
Bugger Me I actually agree with you

nzfatie, Jul 28, 12:49am
People put new tyres on the front of FWD vehicles as they wear 3 times faster than the back ones do!
Shows you how little grip the back ones have, as more grip = more wear.
So vital to make sure the rear tyres are good too.

unbeatabull, Jul 28, 12:57am
No. Grip does not = wear.

Front's wear faster because they are used more and under higher load, as well as W/A etc factored in to help with steering etc.

A front tyre will wear faster under understeering conditions or lack of front grip then oversteering conditions. Rear tyres wear faster under oversteering conditions, or lack of rear grip.

Excellent thread. I think all it proves is that theres more than one "excpert" out there and no one knows the correct (if there is one) answer.AGAIN.
I recently put two new tyres of my Falcon and the shop put the new ones on the front and fronts to back. Car felt better for it and I don't think Im about to slip off the road anytime soon unless I drive like a dork, which probably causes most of the accidents in the first place, not two new tyres on the front.

mrfxit, Jul 28, 2:02am
THATS the most important bit said so far
