Tyre change help and advice

Hi, can anyone help me please. I have a Freelander 2.5 V6 I had the back 2 tyres replaced yesterday. The car was in good working order when it went into the garage but since having the tyres changed it sounds like the exhaust is blowing and sort of rumbling underneath (exhaust has been checked no issues there). I went straight back to the garage who told me that because the back wheels had more tread on them than the front wheels, the wheels are all turning at different speeds and it is the transfer box that is making the noise. He then says only way to stop it is to get front tyres replaced also. Is this correct or is he scamming a lady driver. Please help as need to get this sorted out asap.

are they the same make, model and size tyre as the front?

Ask him to show you the transfer box (it hasnt one).

do not drive the car unless absolutely necessary.

front wheels are driven slighly faster so having slightly bigger diameter on the rear should help

Please tell us all the details written on the tyre side walls - Brand, size, etc. and if you can - the tread depth of the front ones.

There may well be something wrong but perhaps not what you are being told by the tyre dealer.

I would not trust him much as Mad Hat Man is right - a Freelander does NOT have a transfer box.

I fink when the garage says "transfer box" they mean the ird. It does transfer power, but it's a fixed ratio unlike other LR's which have a transfer box wiv selectable hi un low ratio.

Hi RECOMEND ALL 4 TYRES THE SAME MAKE/MODEL/SIZE !

One of the 1st things we did with ours was buy a new set of tyres all round - after reading its history & SCOURING here......
(is that not common sense? )

I changed the rear two tyres on the good ladies car and all was fine but then after a while a rumbling/groaning noise started. I looked at everything, all tyres were ok and balanced, VCU was tested ok, all fluids checked,bearings etc but the fix was to replace the front two tyres aswell to even up the tyre wear. It didnt seem to be that much out but the difference it made was unreal. As for the exhaust could it be that it is just coincidence and that the exhaust has got a hole in it somwhere.
