| Post subject: | Winter tire size |
I have to buy some snow tires this week and am wondering if the anyone has put a set of Firestone Winterforce UV Tires on a CRD? Sears has a really fantastic price on them of $75 a tire. I am leaning toward the 245/75/16 vs the 245/70 size. I know that the 245/70 will fit without any problem, but will the 245/75 fit? I have pounded the pinch weld and heat-gunned the inner fender for more clearance. I have not yet installed a lift due some unexpected funeral expenses with the family. Opinions? I need to order today. |

245/70/16 Michelins really fill up my front fender well with the tires turned about 20-30 degrees |

Well, I ordered the 245/75 size from sears yesterday. They had to be sent from the firestone factory and should be in by thursday. I'll know then whether or not they fit. |

Any particular reason you went with such WIDE tires for snow? I would have thought that the conventional wisdom of wider is better only tracks for sand, not snow / ice...? |

The wide tires are a trade off. The roads here have ice as much as snow. On ice the more rubber with sipped biting edges that contact the surface the better. Also, I drive a lot of back roads which don't get plowed. On these roads a narrow tire is useless unless it can bite through the snow to the road surface which it often can't. A wide tire provides better flotation the same as it would on sand or mud. If I were on highways and plowed streets all the time a narrow tire would work better. http://www.snowtire.info/ |

If you wanted a wider tire, then the 70 series tires would be wider than the 75 |

The second number in the series, i.e. 70 or 75 does NOT indicate width. It an indication of the height of the tire as a percentage of the width(the first number in the series). The number 70 indicates 70% of 245mm (183.75mm high), 75 is 75% of 245mm (171.50mm high), etc. http://www.dakota-truck.net/CGI-BIN/TireCalc.cgi http://en.wikipedia.org/wiki/Tire_code |
