Directional tires can cause unpredictable behaviour. Good acceleration but poor stopping in some conditions, I have been using directional tires for 50 years and they have advantages and disadvantages. This was posted and explains some. "By the way, the reason - the only reason - the military changed to the non-directional tires was that they were NOT DIRECTIONAL. Some of you use a farm tractor or know someone who does. You know it's possible to drive a tractor into situations where it cannot back out. Depending on the individual manufacturers, most DIRECTIONAL tractor tires are 30% to 40% more effective than a non-directional tire going forward and about the same amount LESS effective than a non-directional in reverse. The drill on mounting directional tires on military vehicles was to mount the front tires "backwards" for more traction in reverse. The thinking was that the driver could back out of a bad situation and the directional tire would benefit from the engine weight. Changing to the spare and normal tire replacement could result in having most or all the tires turning "backward" at lower traction. The only way to have the various tires all turning the best way would have required constantly remounting the tires on the rims to suit their location on the vehicles."
Most commonly, wheel balance. Wheel Balance, bad tie rod ends. bad ball joints, cracked or warped dick brake rotors, bad wheels the tires are mounted on, bad McPherson Struts or shock absorbers...the list goes on.
no its ecnamor dab.
get some medicine
Bad tires and bad alignment can cause the car to shake at certain speeds.
My van has bad tires at front and better ones at rear, should wheel alignment be performed with bad tires?
Misaligned axles, bad mounts on the tires, improperly inflated tires.
You could, but it would be more accurate with new tires.
It is not. That is why a lot of tire shops fill tires with only nitrogen.
* Bad Tires * Bad wheel * Failed or bent suspension parts Have the tires & wheel checked first.
If you can have good winter tires fitted to them, there's nothing bad with having 20" tires in snow.
Not really.
