So far they are very quiet and smooth.

But, the car is very darty now. At high speed it wanders at every surface irregularity. I believe that it is from the lower adhesion on the older front tires.

I tried lowering the air pressure on the rear tires (to reduce understeer). No noticeable positive change.

I will end up replacing the front tires very soon.

But, my question for the board is: Is it normal to replace all 4 tires whenever a tire change is needed? Is that what everyone else has experienced?

Generally you should always run the same make/model of tires on all 4 corners. From what I have heard the SPT is an excellent 'bang for your buck tire' offering both good wet and dry grip and longevity.

i replace 2-1 back to front but i second Matts coments for sure .. always same brand and " cut"

WPOZZZ

I think your dartiness could be attributed to full tread on the rears and stuff from the tire mold that has to wear off. Give them about 300 miles and I think they will settle in.

I replaced mine (all 4) with Sumimoto and have the rear wander on slightly uneven road surface too. This is the very first time I experience this. Usually, the front wander and/or jerk do to many reasons. Now, once in a while my butts wander around like a fish cruising slow :lol: sometimes I feel a little affraid when I pictured my rear wheels are comming off.

Experts, do you think our rear wheels are having too much toe-in or toe-out?
