Car Talk: Each wheel makes its own turn going around corner | T...

Dear Tom and Ray: I live in New Hampshire and have a 2002 Saab 9-5 Aero. About 10 weeks ago, after putting on the snow tires, I personally put the little blue "hub covers" with the Saab logo on the center of each wheel.

anyone who drives a vehicle with part-time 4wd knows this.

All cars, rear wheel drive, front wheel drive, full time four wheel drive, 4x4, part time four wheel drive, all cars have front tires that travel different distances when turning. Thus, they would all realign the logos, every time, instantly.

Jus sayin`

Now, as for a GMC Sierra with rear wheel steering, hmmm.

the reason i say anyone with part-time 4wd knows this, is because this is the reason you should not drive part-time 4wd on pavement with all four wheels engaged. with all four wheels engaged, they are locked together and spin at the same rate. if you are not on a loose surface, you will damage your vehicle due to driveline-binding/wheel-hoppin g.

4-wheel steering does not change the fact that the outside wheels in a turn spin more/travel farther.
