Re: Two new tires - front or rear? (front wheel drive)
With all due respect to the tire changers in the shops mentioned above, and to those posters who disagree, I like the new ones on the front.
The only advantage I can see in putting the new ones on the rear is better drive traction (RWD). But I'm less concerned with the traction needed to go than I am with the traction needed to stop. My feeling has always been that:
1. The front tires carry the weight of the engine and most of the tranny weight. If there is a situation of stress (puncture/blowout, etc.) I'd rather have the front a little better protected against failure. I doubt that a sudden rear wheel failure holds quite as much potential for disaster.
2. When braking I'd rather have the tread where most of the braking pressure is, and that's the front. If I'm locking them up, I doubt that having good tread on the rear gives me much protection against the rear end swinging out, but in front it may help me avoid a skid. If the front wheels break loose in a skid, you're usually in much deeper trouble. Driving in cold weather environments exacerbates this concern.
Oh, this too; in well over fifty years of driving, I've hydroplaned once - and that was preventable had I been paying attention...!
