Anybody had any problems with a bad wheel wobble under hard acceleration? I have had trouble with vague steering from nearly new, putting it down to the 20" wheels not being standard.
The problem is now worse and when on a motorwary, every time I accelerate, I get a bad wobble through the steering, which stops as soon as I let off the gas. It also wobbles when steering is turned slightly to either side when at speed.
ANY IDEAS

Check the load rating of your tyres, D3 needs 112, a lot of 20" tyres are only 107 rated, okay for RRS.

Under load rating is unlikely to generate a wobble.
The first obvious answer might be balancing ...but if it's only under acceleration then it could also be a driveshaft issue. Get get your stealer to check it out  Existential Phenomenologist.

DG, I agree with your thoughts, but I've also experienced a V8 that tried to throw me off the road went it was opened up but behaved like a Sunday driver when driven normally. A new set of Pirellis and it was cured.

Donald I don't wish to give an impression of disagreeing out of hand ...it's just that even with tyres being specced as under the D3 load rating in a legal sense...the manufacturing margin for 107's should provide that they are in fact technically capable of dealing with the D3's weight....hence my suspicions in other areas  Existential Phenomenologist.

Maybe a slightly buckled alloy - especially as you are running larger wheels....
On my other car, none of the wheels are still fully true  . the tyre fitter said it is very common on heavy cars with wide wheels, as
Quote:"I bet you straddle them speed bumps that are 3 lumps in t'road don't you. Everyone does, it just means that the weakest part of the alloy is taking all the load of the car - knackers the alloys mate
Might be worth checking

I had an 'egg' on an old tyre/car once - just a slightly raised profile. Hardly noticeable when viewing, but gave me a wobble at certain speeds. TDV6 SE Auto, Cairns Blue, Club AT2, Club Lenser, Club Trangia, Club Labrador, Club Chainsaw, Club Yorkshire

could be down to steering damper (or lack of), as the RRS uses a damped steering rack (required for running 20's), and the D3 doesnt have this. It would appear that the D3 non-dampened rack is borderline for running 20's, some its OK (and quite a few members are running fine), whilst others (me included) couldnt get a satisfactory wobble free ride (and I had my rack changed and it still didnt fix it). Its a  (or lottery), as the 20's look great.
