Recently changed all four tyres from OE Bridgestone RE050 to GY Eagle F1 GSD3 XL and now suffer a vibration through steering wheel at around 70 - 80mph which then clears. Have had them re-balanced at a different tyre fitters (French ones - they drive like maniacs!!) and I am still suffering with the same problem. Have searched on here and the only thing which seems to explain it is the balancing but this has been done twice now! The only thing which appears different with the balancing from the OE tyres is the F1's are balanced with stick on weights on the inside of the rim and the OE's were balanced with weights on the outside edge of the rim. Any other ideas?? Car is a MY05 WRX PPP 18K miles with original 17" wheels for info.

Hi there,

This does sound like a tyre/wheel out of balance.

Worth getting them rebalanced (again), sometimes a new tyre can move on the rim due to the stuff they use to ease it onto the rim and it being new - without getting into a long explaination.

could be a bent rim but not likely if it did not do this before.

could be a disk has moved slightly, where the pads/disk done at the same time?

Best drive carefully for the first day or so, you should anyway as new tyres can often have release compund on them (used to aid their release from the mould)

Im having the same wobble at 80mph having recently fitted 215/45/17 91Y F1's XL, and Ive had the fronts re-balanced and its still the same.

I think the tyres themselves may not be perfectly circular.

I also found they feel very floaty at high speeds, like they are getting thinner.

Great at throwing around bends and in the wet.

Ahh, check your pressures are correct, sound like they might be a bit high to me.

Cheers for your replies and advice. I've checked my pressures and they are as the handbook states so I'll get the fronts balanced again and see if that works.

Cheers Barney.

Mine are the same size tyres.

My pressures are 34 front 32 rear, I may drop the fronts to 32 and see how that goes.

Still not happy with the tyres thou, Im sure they are egged shaped!

Move the tyres from the rear to the front, one at a time, then take the car out for a drive, if you still get vibration then the chances are its something else than the wheel (drive shaft for instance) but hopefully it should move, basically just eliminate any possibilities that its the wheel (could be the tyre itself).

I've had vibration with my Wagon since I got it - had two new sets of tyres since then and the vibration never changes

Had full 4 wheel alligement done too - but again no change.

Sounds like the drive shaft as well? (would that need a replacement?)

I would'nt have thought it was my driveshafts, as it was fine on the old set of tyres and wheels, then as soon as I fitted new alloys and tyres the wobble started.

Stupid question but they are on the right way, Ie: arrow pointing forward on all four???

As said, swap the wheels from front to back and see if it moves, it could be a buckled wheel that was on the back and is now on the front which would show move vibration through the stearing wheel.

Cheers for all the advice with this, will swap wheels at weekend and see what happens.

Update on mine, got it sorted! The reason my Eagle F1 XL's vibrated at 80mph was the fact I had'nt fitted the spacers that came with the new wheels! Put them on, test drove, and no vibration at all............very pleased its now sorted.
