Had my MR2 Turbo stored during winter. I even put styrofoam blocks under the wheels. However the ones I put under the rear wheels were quite hard and didnt really flex.

Now I've got a vibration from the rear at 50 - 65 mph. Under and over that it's absolutely fine. Can't tell if the problem existed last season since one of my wheels was buckled. Car is on 100% straight and balanced wheels now.

Any ideas how to get rid of the problem without buying new tyres?

 

Rolling burn out?

 

Never heard of getting rid of flat spots of tyres.

Think you will just have to replace them

 

sounds fun

 

fit the spare wheel, and see if you still have the problem

 

Dont store the car and use it lol.Can you not out the car on axle stands when your not using it.

 

i expect its the metal banding thats bent so i think you may be buggered but id would put 70psi in and drive them til warm and see if it helps

i dont knows if thats bad but ill try anything once

 

check the tyres rated maximum pressure before you try and put loads of air in it

 

double post

 

How many years was it stored for ? Cant say Ive ever had it happen a car even if sitting parked up for well over a year.

And clearly if the wheels/tyres balanced fine, the wheels/tyres are not the problem. If if the tyres had flat spots ( which actually only occurs after a severe lock up ) the problem would be there at all speeds.

They dont suddenly go from round to flat then round again.

Swap wheels back to front and see if it moves. But it usually takes a huge issue on rear tyres for it to actually be felt.

 

Hi there,

After driving again, I think it's actually not the tyres but the driveshafts. Possibly even an engine mount as I've discovered that it only occurs under high load at relatively low rpm.

Thanks for the advice anyways!
