ok, here goes, went to our local tyre place, had the front tyres measured, and the back changed, same make new tyres, noise gone in all circumstances but an occasional clunk at low speed in traffic, this i can live with, but i,m confused, will change the front prop soon, and change the auto box oil ...

bmw in york did it, main dealer,said all was well, i have little bit play in the front prop u/j nearest the trans box,

got tyres, a slight reduction in clunks but still there, had difs oil levels checked, all ok, and checked prop shafts for wear on u/js, front shaft has some wear, back seems ok, ho hum, !!!,  :(davey

getting new tomorow, will let you know the outcome, ........davey

altho my tyres arnt star marked on the rear, i have measured the tread depth, 3 mm on one, 4.5 on the other,would that difference make the radious problem, ?seems to bear out the tyre thing, davey

i,ll keep you all up to speed as i try the tyres, and check out the prop shaft u/j, davey

ok, i,ve got staggered wheels, 9s on back, 8s on front, 255.45.18, back,  235.50.18 front, ??, davey

ok, i,ll measure in the morning, thanks again, davey,

i know i,ll seem daft, but what does staggered mean, davey,

the backs, 255.45.18 michelins, the fronts 235.50.18 khomos, no stars, rgds davey

ok, i double checked, 255..45..r18.rear, ....... 235..50..r18. front,  ??

so get 255...55..18s for the backs, and make all the same???

also, i got 235...55..18s on the front, and 255..55..18s on the back, should that make a difference??. rgds davey

great, thanks for that, i,ll check that as soon as it stops raining, lol, rgds davey,

i,ll check the tyre sizes tomorrow, they not run flat, rgds davey
