Edmund's Feature Article: Tire Safety: Don't Ignore the Rubber on the Road
For dedicated winter tires, also have a look at the Snow/ice winter tires discussion topic.
And we were on topic, so there was nothing to interrupt. I think 63 mostly wanted to brag on his great deal.  Steve, Host |

I am getting a Z4 with Potenza RE050A 225/40R18 front & 255/3335R-18 rear run-flat tires. I had asked a question about winter driving on performance tires back in November. I held off purchasing the car until now primarily so I didn't need to worry about driving in bad weather. Back in November, kyfdx had indicated there is a problem when the temperature drops below 40F. I am picking up the car tomorrow and will be driving it 150 miles to get it home. The weather forecast is for temps in the mid 30's. How dangerous is this? Should I put off delivery until it is warmer?

You'll still be safer than the other 80% of the public that are driving on worn and under-inflated tires... Congratulations on the car.. I'm guessing that is the 3.0 with the sport package? regards, kyfdx

Replying to: kyfdx (Feb 18, 2005 6:55 am) Yes. I probably only have 3 weeks or so where I will need to dodge the weather. Next year my son is off to college and I will have Grand Prix to drive in the winter while the Z4 sits in the garage. Thank you for all of your help in the various threads where you post. |

| Exactly as kyfdx stated. Be careful when you first start out, especially when turning. No full throttle until you've gone a mile or two. The tires are hard and "slippery" when -they- are cold. You also loose a little traction when the tires are warm but the road is still cold, though most wouldn't notice that difference. If it snows, park it until the snow melts. I can't even get my RX-7 down the snow packed back alley, the tires are so slippery. Mine are Mich. Pilots, but most "performance tires" are the same when cold. | |

KUMHO's ECSTA V70A has been voted best tyre in a test of road-legal track day tyres by German motoring magazine AUTO BILD. Beating off the challenge from similar products from Michelin, Toyo, Yokohama and Pirelli, the V70A was given top marks for its uncompromising sports-orientated performance. The AUTO BILD testers praised the tyre for its excellent lateral and directional stability as well as its dry braking ability. AUTO BILD is one of Germany's leading motoring magazines with a readership in excess of three million. Nominated as the control tyre for several production car race series, the KUMHO V70A is available in some 27 sizes from 13" to 18" and in a choice of compounds. Commenting on KUMHO's success, European motorsport manager Steve Thompson said: "The V70A is one of the most versatile tyres in our range and can be used for anything from tarmac rallying to hill climbing. This win proves what we have been saying for some time: the V70A is the ideal tyre for the serious track day enthusiast." Click on the magazine image to download a pdf of the article (5.2MB)

Replying to: edh (Feb 25, 2005 5:13 am) Myself I'll stick with quality in the tires over advertising and car mags recommendations. You don't know how many percs are given at trade shows to gain those recommendations. I don't drive my Buicks in competition much anymore so I really don't know how the quality compares, but I do know Michelin has given me round tires that stay round after 20K miles and don't need rebalancing often. Michelin has given me long life 100K on 80K tires (XH4s, XOnes). I stick with what works. If I did drive much more aggressively in a sporty car, perhaps the grip factor in extreme driving would make a difference. But I couldn't get my new Harmonys to break loose on a typical dry snow in quick movements. Another good choice--for me and mine, IMHO. |
