My lovely wife got a flat tire with our RX300 (2002) and drove approx 200 m before she stopped. This resulted in a mashed tire which wasn't able to repair.
The tire-guy told me to change all the four tires due to the 4W-drive, but the other tires where only 15000km old. I only changed the pair of tires (note: same brand and model as the rest). It is snow tires and I do see a deferens in the depth of the pattern between the new and the old tires.
Can it brake down the 4W-drive mechanics to have slightly different wheel size between the front wheels and the rear wheels?
