After refurbing the wheels I fitted new tyres,bridgestones mz' s on the front but none were available in Europe for the rear so I went with SOO1's (generic 050) in the correct size, now I feel that when changing up whilst "making progress" the back seems to twitch slightly?, disconcerting at speed on a bend/roundabout. So could this be the tyres mismatch or maybe I need to get the alignment done, going to call the suppliers tomorrow-camskills- since they said that the tyres would be fine together. Ta.

 

Probably just the fresh rubber bedding in?

 

Are the S001 slightly softer in the sidewall than the MZ if so that might be the answer?

 

I've had new tyres feel really wobbly for the first 200 miles or so before..!

 

If you're referring to the release agent on the tyre then yes it could but I wouldn't describe it as wobbly. I am assuming that the OP has covered some miles on the tyres before pushing them especially at this early stage in the year.

 

I had new MZ fitted last year and at no point have they felt anything else than planted even when "pressing on". Granted my idea of pressing on may not be the same as yours.

 

I had the chance to play with the sidewalls of some MZ's and standard versions when off the car and the difference really shocked me! You can flex the sidewall with your thumbs on the non MZ's!

 

Almost certainly because the sidewalls are softer then what you're used to. Had to ditch the Falkens I put on the rear of mine after 300 miles because they just made the car feel terrible.

 

Seems the tyres are the cause, softer side walls allowing a little flex, camskill say this shouldn't be a problem as the load ratings are the same and have no other problems reported but there is something. I'll persevere a bit then see how they feel, maybe a couple of extra psi in them may help?

 

Probably make it worse.

I had the same issue when they accidentally put Porsche-spec S-02s on the back of the car. It was like an 86 prototype! Great fun, but they corrected it and it was preferable.

You cannot mix tyres, even if its name is similar.
