645921 2008-03-26 00:18:00 I asked him what Firestone recommend and he said the front, so I put the new tyres on the front and the half worn ones on the back .

I wonder if Firestone actually do recommend this . The Bridgestone/Firestone Group seem silent on this except that they have the following on mixing winter and summer tyres . . tiresafety . com/images/Tire%20Replacement%20Manual . pdf" target="_blank">www . tiresafety . com

"Winter tires are best applied to all wheel positions .

If winter tires are applied to the front axle of any vehicle, they must also be installed on the rear .
- this applies to all passenger cars and light trucks, including front wheel drive, 4x4 and all-wheel drive vehicles .

Do not apply winter tires to only the front axle

If winter tires are installed on the rear axle of any vehicle, it is recommended (but not required) that they also be installed on the front axle .

All winter tires applied should be the same speed rating . It is generally acceptable to apply winter tires with a lower speed rating than the OE tires for use in winter conditions; however, speed should be reduced accordingly . It is the "top speed" of the "slowest" tire on the vehicle which limits the vehicle's top speed without tire failure .

Never place bias ply or bias belted tires on the rear axle if radial tires are on the front axle, regardless of which axle is the drive axle, unless the vehicle has duals on the rear . "

"Members of The Tire Rack team had the chance to experience this phenomenon at Michelin's Laurens Proving Grounds . Participants were allowed to drive around a large radius, wet curve in vehicles fitted with tires of different tread depths - one vehicle with new tires on the rear and half-worn tires on the front, and the other with the new tires in the front and half-worn tires on the rear .

It didn't take long for this hands-on experience to confirm that the "proving grounds" name for the facility was correct . The ability to sense and control predictable understeer with the new tires on the rear, and the helplessness in trying to control the surprising oversteer with the new tires on the front was emphatically proven .

The majority of drivers probibly don't know what oversteer or understeer is and probibly never have experienced it . In th 40 + years I have been driving I know I haven't .

Obviously somebody thinks all drivers should be driving their tires and vehicle on the ragged edge of control .

Immature and irrational . :knuckle-dragger:

Most . . . make that almost 100% of the everyday drivers have never had a car driven around a diminishing off-cambered curve with a controlled slide and countersteer while nimbly dancing on the throttle and the brake to keep things in line . . . . and that's the way it should be . :cool:

Passenger cars are just that: passenger cars . They are not Formula 1 or Sprint cars . . although I see a few that should be in the destruction derby .

Leave the average (read: Normal) people alone and they will likely survive . . . if not from astute planning on their part, by at least accidentally surviving the rigors of daily life .

Good tires on the back are the safest bet . . . and not even Andy Granatelli (find him on this page ( . google . com/imgres?imgurl=http://www . rumbledrome . com/images/parnelli . jpg&imgrefurl=http://www . rumbledrome . com/60stats . html&h=229&w=366&sz=9&hl=en&start=22&tbnid=SWDF5ASxm4gSvM:&tbnh=76&tbnw=122&prev=/images%3Fq%3DAndy%2BGranatelli%26start%3D20%26gbv%" target="_blank">images . google . com 3D2%26ndsp%3D20%26hl%3Den%26safe%3Doff%26client%3D firefox-a%26rls%3Dorg . mozilla:en-US:official%26sa%3DN)) would argue that point .

On the race track . . . do what you want . . after all that's why it's called competitive racing .

On the street . . . just be smarter than the average idiot and you might survive .
