Question about Tire Rotation (non Camaro)

I just bought a 2002 Pontiac Montana Minivan. The Tires on the rear seem to be in pretty good shape, but the ones up front are pretty much ready for replacement. Would it be a good idea to simply take all four wheels off and switch them around (front to rear and rear to front), then replace all of them when the ones up front are also worn down?

Re: Question about Tire Rotation (non carmaro)

Too bad.
I bet you missed a couple of tire rotations?

If your tires on the front are not too bad then you could rotate and get a bit more life from them. As long as they are still safe !!!

Don't push tires beyond the warning signs. Nobody wins that bet.

Re: Question about Tire Rotation (non carmaro)

This goes against what seems logical but it's recomended to put the new tires on the back and the used rear tires get moved to the front.

From Tire Rack dot com,

Quote:
Most vehicles are equipped with the same size tire at every wheel position. Ideally all of these tires should also be of the same type and design, have the same tread depth and be inflated to the pressures specified by the vehicle placard or owner's manual. This combination best retains the handling balance engineered into the vehicle by its manufacturer.

However due to a front-wheel drive vehicle’s front tires' responsibility for transmitting acceleration, steering and most of the braking forces, it's normal for them to wear faster than rear tires. Therefore if the tires aren't rotated on a regular basis, tires will typically wear out in pairs rather than in sets. And if the tires aren't rotated at all, it's likely that the rear tires will still have about 1/2 of their original tread depth remaining when the front tires are completely worn out.

Intuition suggests that since the front tires wore out first and because there is still about half of the tread remaining on the rear tires, the new tires should be installed on the front axle. This will provide more wet and wintry traction; and by the time the front tires have worn out for the second time, the rear tires will be worn out, too. However in this case, intuition isn't right...and following it can be downright dangerous.

When tires are replaced in pairs in situations like these, the new tires should always be installed on the rear axle and the partially worn tires moved to the front. New tires on the rear axle help the driver more easily maintain control on wet roads since deeper treaded tires are better at resisting hydroplaning.

Hydroplaning occurs when the tire cannot process enough water through its tread design to maintain effective contact with the road. In moderate to heavy rain, water can pool up in road ruts, depressions and pockets adjacent to pavement expansion joints. At higher speeds, the standing water often found in these pools challenges a tire's ability to resist hydroplaning.

Exactly when hydroplaning occurs is the result of a combination of elements including water depth, vehicle weight and speed, as well as tire size, air pressure, tread design and tread depth. A lightweight vehicle with wide, worn, underinflated tires in a heavy downpour will hydroplane at lower speeds than a heavyweight vehicle equipped with new, narrow, properly inflated tires in drizzling rain.

If the front tires have significantly less tread depth than the rear tires, the front tires will begin to hydroplane and lose traction on wet roads before the rear tires. While this will cause the vehicle to understeer (the vehicle wants to continue driving straight ahead), understeer is relatively easy to control because releasing the gas pedal will slow the vehicle and help the driver maintain control.

However, if the front tires have significantly more tread depth than the rear tires, the rear tires will begin to hydroplane and lose traction on wet roads before the fronts. This will cause the vehicle to oversteer (the vehicle will want to spin). Oversteer is far more difficult to control and in addition to the initial distress felt when the rear of the car starts sliding, quickly releasing the gas pedal in an attempt to slow down may actually make it more difficult for the driver to regain control, possibly causing a complete spinout.

Re: Question about Tire Rotation (non carmaro)

It all depends on how worn the front tires are. Is it front wheel drive or all wheel drive?

If it's front wheel, you can probably get away with moving the fronts straight back and then moving the backs diagonally to the front. This would give you good drive, good steering and good braking.

If it's awd, then ideally you'd like to have all 4 tires have the same amount of tread. This is because awd monitors which tires have more or less traction and transfers power to the tires with more traction. If they aren't equal, it will think it's in a slippery situation all the time.

Well replace them

The essentaul thing is having good tread all round..I do prefer the better tread up front..thats wher 60+% braking is, steering grip etc.
But im not one of those people who takes their tyres, be it the wifes little corolla , the vintages cars or the Camaro....
There is no differnce at the end of the day between faulty brakes and bad tyres...the result is the same....

The only time I rotate tyres ..Front /back is when 1 pair needs replacing...and thats the fronts which moved from the rears when replaced the last pair....AND at the same time a full caster / camber/toe alignment

My Spelling is not incorrect...it is creative

From Tire Rack dot com,
This sounds most logical

Thanks :-)

Re: Question about Tire Rotation (non Camaro)

I'd say you're better off replacing all 4 and rotate as recommended.

My logic is that if you buy 2 tires, you'll need to buy 2 tires next time, since the newer ones are still pretty good.
