Poor Handling at all speeds

Recommended Posts

hi got a 1998 996 C2 and recently changing rears tires from contis to Good Year F1s and handling all of a sudden terrible and dangerous! tried adjusting pressures but appears leat bad at recommended 36 psi. the car steers round bends and corners better than it ever has but in a straight line at 30mph towards just wanders all over the road just as if it's getting blown across the road, i can be holding the wheel dead straight and i'll just move across the road! **** scary! can't think what is wrong so any help would be great..... as i said i've lower pressures to 32 up to 36 but no change. COuld it just be the change of tires? i would have thought alignment but it was perfect before the new tires, thanks

Run rear tires at 44 psi. I would check all wheel bolts and run out. Jack the car up so both tires are off the ground. Block front wheels. Turn off TC and run in first gear at idle. Make sure there is no obvious wobble.

lotusrock, just so I can understand, do you have all 4 new tires or 2 old Conti's up front and 2 new GY's in the rear?

Never a good idea to mix tire brands and tread depths.

Hi,

You might want to check that your tyres have been fitted the correct way round - Eagle F1s are available as both directional and asymmetric versions - both of which need to be fitted correctly to ensure they perform properly.

Check the sidewall of the tyres for markings indicating either the direction of rotation or the which is the inside/outside edge. This should tell you if they're fitted correctly.
