That change in size shouldn't make any significant difference in acceleration. Simply not enough diameter change to affect the ratio much. Yes, the odometer will see the change, but not the "seat of the pants" or "assometer." Based on your other post, I think you were running the previous tires GROSSLY over-inflated. 40 PSI on a light vehicle is ridiculous. Go with whatever the placard on the vehicle says, ignore the "maximum pressure" ratings on the tire. |

Last night I even accelerated up a hill in 5th gear. There are a couple hills I was unable to drive up in 4th gear because of the curves, and had to shift to 3rd to gather momentum to get up the hill. I can take it in 4th no problem. Of course, because of the stiffer sidewall, I can get into the corner a bit faster, too. The difference is amazing. Also, I use this car for a job, and I have to pay for fuel, so I want all the mileage I can get. |

Okay, so you bought lousy tires, and you noticed the handling was poor and the didn't last long. >So, I had some 185/60-14s hanging around and had them mounted. WOW!!! The >acceleration is amazing, even going uphill in 4th gear (I had to downshift >to 3rd before...). Handling is 100% better, and the odometer is finally >right (it was 5% off (-) before...) So you noticed that even with the incorrect tires on the car, good quality tires perform a whole lot better than $29 specials. >Any comments? I haven't been able to 'calibrate' the speedo yet. Even >though the odometer was off before, the speedo was correct according to >three different radar 'speed reminders' they put by the side of the road, >and a couple of 'official' radar readings as well... I think your differences have a lot more to do with the quality of the tires than with the tire size. Tire size makes some difference, sure. But lousy tires are just lousy. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Maybe the head on crash from the poor contact patch on these tires will do it. The tire sidewall pressure is the MAXIMUM that tire can withstand NOT the pressure you run them at. You get sidewall splits, increased tread wear in the center, less resistance to tire damage, easier puncture damage (and usually worse damage due to the higher pressure), Less braking ability, poor cornering in the rain (if you can even turn with the reduced tire contact). Wait till you hit a wet spot and try to brake.. Slip Slidin' Away are not just song lyrics.

Bullsnot. The way a tire "looks" doesn't mean anything. Different tire designs may bulge a little more or less, but that has nothing to do with the actual contact patch, OR with the rolling resistance. You're not necessarily saving fuel by overinflating your tires. Poor cornering performance caused by overinflated tires scrubbing sideways costs fuel too. |

The Continental all- seasons that came stock on my '02 GTI were pretty bad, but I think these are actually worse. Either that, or the Impala's suspension geometry just sucks. nate |

Every manufacturer has both good and bad tires. The Goodyear Integrity that came on my Toyota were crap. The collective wisdom of tirerack.com rates them near the bottom. The Goodyear Fortera TripleTred that I replaced them with are great. tirerack rates them number one among highway all season. |

Agreed. >The Goodyear Fortera TripleTred that I replaced them with are >great. >tirerack rates them number one among highway all season. I rather like them, but they don't deal as well with wet pavement as the old Aquatreads do. They don't have problem on grooved pavement the way the Aquatreads did, but I tried them after the Aquatreads were discontinued and wasn't all that impressed with overall handling and wet-weather performance. The Aquatreads were wonderful. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I suspect you must be joking. First of all 44 psi is the maximum tire
preassure not what you should use. Buying the cheapest tire you can find? Either this is some troll bs or you are to dumb to drive a car. |
