Conventional tyres damaging wishbone?

[fourmations]

hi all

i have conv. tyres on the front of my r53 S
and got a screw in it, anyway when i was getting it fixed
the guys was saying my wishbones are on the way out
and kicked the tyre to show me the "give" and it was duly there

but anyway, he said its because i have conventional tyres
and that the suspension is set up for r/f's and the difference
in the tyres has caused this,

is this true, i was planning to change my rear r/fs for conv as well
but now i am reconsidering...

the car has tiny mileage is that makes any difference (2005 with 34k kms)

many thanks

As far as I know the suspension system is exactly the same whether run flats or normals are fitted.
The rubber metalastik suspension mountings do perish and wear and can cause the suspension to move, only slightly, but enough to feel the effects sometimes on the car handling and affect the tracking and thus tyre wear.
Mileage doesnt tend to make much difference as its age that causes to problem.

I agree. Find another shop. Yep, I think it's your wishbones said the chicken pluck-er!

What they said, he's talking absolutely nonsense.

Rubbish.......tyres would make no difference. In fact I have heard that the R50/53 Miini's were designed to run on normal tyres by Rover engineers.......runflats were a later addition requested by BMW and some models of Mini were sold with normal tyres as standard anyway.

thanks a million for the feedback,
any wild guesses on what the wishbone bushes job should cost?

Hi: just to back up the concensus here with some numbers: I've managed 60,000 miles on conventional tyres and had no suspension problems yet (90% motorway driving)

Cheers..
