| 645831 | 2008-03-03 09:36:00 | There are those in the tyre shops who still recommend best to front. There you go. Don't listen to anyone, having a blow out on either rear or front is not nice, personally I'd have good tyres on the front (because it's fwd) but that doesn't mean have crappy tyres on the back. |

| 645832 | 2008-03-03 09:44:00 | I have had a blow out on the passenger side back wheel at 90 miles an hour in Africa years ago with five people in a Toyota Corona 1500, the first model, if it had been the front we would have been dead. Doesn't matter if it is front wheel or rear wheel drive put the good tyres on the front. For a good driving experience and for best handling you need over steer not under steer, in other words the back should swing out not the front. |

| 645833 | 2008-03-03 10:07:00 | I have had a blow out on the passenger side back wheel at 90 miles an hour in Africa years ago with five people in a Toyota Corona 1500, the first model, if it had been the front we would have been dead. Every night there is some police car chase reality show on tv where the stolen car loses its front tyres on road spikes and keeps going. Doesn't matter if it is front wheel or rear wheel drive put the good tyres on the front. For a good driving experience and for best handling you need over steer not under steer, in other words the back should swing out not the front. Tell that to all the dead Porsche drivers. The tyre industry say, if you are only changing 2 tyres, put the new on the back, they aren't saying leave the front on until they are stuffed. If you are that worried replace them when they still have plenty of tread left. www.tyresafe.org |

| 645834 | 2008-03-03 10:28:00 | Porsches drive in straight lines because all the torque on the back wheels lock up the diff and they slip off as soon as you manage to corner because of the rear tyres wheel spinning, this is completely different from what we are discussing. The front of a Porsche is light compared to the back where the engine is and no matter what tyres you have on the front it will still tend to travel in a straight line under acceleration when you try to turn. You need special skills to drive a powerful rear engined car the tyres need to be good on all the wheels as well. Always put your best tyres on the front in any normal car, you have been warned. You always need over steer not under steer this is an acknowledged fact, I do not know why anyone is saying otherwise, powerful rear engined cars are an exceptional case where to over steer is caused by the weight of the engine and the spinning wheels causing loss of adhesion, you cannot steer out because the front wheels are not in control unlike with a V8 car with the engine at the front. |

| 645835 | 2008-03-03 12:58:00 | Common sense says put the best tyres in the front. But experts say at the rear. I think I'd go with the experts. | Greg (193) | ||
| 645836 | 2008-03-03 16:20:00 | On spite of everybody's good intentions . . and I haven't read all the responses yet . . . The ONLY place to install new tires is on the rear . Reason? In the event of a tire failure, the front wheels are controlled by the steering wheel, brakes and the general direction of travel in the first place, making it very much easier to correct for drift and pull to the bad tire side . This will allow for the greatest amount of control and keeping the vehicle out of losing complete control . If you mount the new tires on the front, then should a rear tire fail, the back end (which is not steerable) will likely sway and shift to the bad tire side and usually a roll-over happens . The facts of single vehicle accidents were studied in depth by the Automobile Club of America . . . and the results are all concurring with new tires on the back, older tires on the front . In olden days . . . it was usually the opposite . . . but that was because tires had cotton or linen cords and the newer tires could absorb more road abuse than the rears and the idea of a tougher, more resilient tire on the front made more sense . These horseless carriages usually didn't go as fast as their modern counterparts and loss of control at 3 mph was a lot easier to manage than at 70 mph . Now I'll go and read the rest of the posts here . . . . . . |

| 645837 | 2008-03-03 16:29:00 | Take this to the extreme, would you put bald tyres on the front and good ones on the back, I don't think so . Zero common sense these days especially amongst experts . Loosing the back wheels is easy to control, in fact desirable, but front wheels slipping out and back wheels holding is the worst thing that can happen and very undesirable . In a front wheel drive car the back wheels slipping out can always be controlled by planting boot and steering out of trouble if the front tyres are good . He is talking a load of hooey . Usually I like and admire your comments . You are so TOTALLY WRONG HERE that if you were in any way more so, you'd be arrested for inciting death and destruction on the roads/highways with your bad bad bad bad bad advice . What you proffer is a mixture of old wives' tales and a total lack of knowledge of the dynamics of an automobile and the incidental forces that control it's forward and steering/braking motion . Put you fat mother-in-law in the back seat and try driving on a single low tire in the back and navigate a turn or quick maneuver sometime and see how the forces try to flip your car and force you into an unwanted lane change . . |

| 645838 | 2008-03-03 18:49:00 | A front wheel blow out is death at high speed, a rear wheel blow you survive, I know I have done it and lived, what you are saying is B. S. Joe. Remember I have been driving fast cars since I was 12 in Africa, I have been in a number of accidents and I am telling you if your steering is compromised you don't stand a chance but if you have control of the front of the car you may be able to compensate for a sloppy back pair or a blow out. I assure you I do understand the forces involved, Applied Maths is a specialist subject of mine and I am particularly interested in Dynamics. If you can't see that bald tyres belong on the back and not the front then I can't help you. |

| 645839 | 2008-03-03 19:10:00 | I have listened to Joe and Zqwert and have decided to put one on the front and one on back,just in case. | Cicero (40) | ||
| 645840 | 2008-03-03 19:14:00 | I still would put new tyres on the front, until I see some hard evidence and stats against it. It just seems right. Besides, drifting is fun. :p I'd rather roll over than sledge straight into a power pole any day. Rolling over isn't nearly as bad as it's cracked up to be, although if you end up in a fence it can get interesting, as posts do tend to come through the windscreen. I have had several roll-overs, none of them at high speed on a road, but I know several people who have survived (in pretty good condition too) massive rollovers, one chap at 170, missed a corner and barrel-rolled his Integra about 9 times, he walked away. Other people have simply failed to navigate a corner at 100kph, whether by driver error, or dodgy tyres/ice, and ended up in a bank or power pole and killed themselves. I would like to see some stats on this kind of thing. |
