[quote="CVPost-MarkB_MI"](quoted from post at 10:27:04 12/11/17) Eh, not really.
On front-wheel drive vehicles, the front tires handle all of the acceleration force and (because of weight distribution) the majority of the braking force. A tire will not slip sideways until it breaks traction, either from acceleration, braking or lateral forces. And under most conditions, the lateral forces on rear tires are negligible. So about the only thing than can cause rear tires to slide on a FWD vehicle is braking, and since the advent of ABS brakes, the rear brakes can't lock up.
Spend your money on good front tires. As long as the rear tires have enough tread to be legal, they're fine.
FWIW, a trick to use on slick surfaces is to throw the transmission in neutral when going around a corner. This really helps with FWD vehicles, but it works on RWD and 4WD as well. Why does it work? Because with the transmission in neutral and your foot off the brakes, there is no longer any torque on the tires. Since the tires are free-wheeling, all of their traction is available for lateral forces: steering and skidding.
Mark B your posts are just so far out that I have to respond. If you were to take any instruction in competitive driving, you would be taught early on about the need to POWER through turns, why? because as long as the force pushing the car ahead is substantial the effect of the sideways force is reduced. Following your suggestion here could get someone killed!!! You really should look into this very soon.
Then the idea that sideways forces on rear tires is negligible is in further out there! How could that possibly be??? The force on front and rear tires comes directly from the weight that either is carrying. More weight on the front puts more lateral force on the front. and the same in the rear. Moment arm comes into play as well. If you put traction weight behind the rear axle it provides more downward force on the tires. but it also adds more lateral force, which will cause the tires to break sideways traction more readily. Watch some you tube videos and observe how cars break traction in the rear and spin out.
Mark B your statements are very very dangerous. Someone could believe you and get killed. Please look this up or consult a driving school instructor.
