tyres

[russ25]

have any one tried or heard of what general grabbers AT tyres fitted to 20" what are they like? thinking of getting them for winter etc.

Never heard of them

Watch the rolling diameters on the 'coarser' tread patterned tyres.  Get it wrong and night night diff!  It's happened to a few on here now.

There's a long thread on winter tyre choices.  Well worth a browse

If it helps I've got General Grabber AT on an older shogun running on 16's and on the wife Discovery2 on 18's.  On those 2 cars I rate them a lot, been very good while towing and during the snow and bad weather up here in Scotland over the last year. 

They do have deep tread though, come with ~11mm rather than the usual 8mm.  Not sure about them on an X though.  I 'thought' the diff probs happened with big differences between front and rear tread (so front and rear have different rolling diameters) but I could very easily be wrong ! 

Be interesting to see how an X looks on a set though.

It usually is the front rear difference that causes the upset, but with deeper treads it might do the same depending upon the manufactured tolerance on the tyre diameter.

Allegedly the '*' marking on tyres indicates the correct diameters for BMW - according to my local Dealer anyway.  Exactly how big the real world difference actually is against non'*' tyres no one has ever said.

The probem is with staggered set up (255/285; 275/315). Its not only about rolling. "*" marked tyres have different drag front to back vs non "*" marked, to compensate  different sizes. On "normal" set up (255/255;285/285) it does not really matter what tyres you put as long as they are same make and same tread depth. General grabber on x5? sorry, for me its a big no no. They look awful.

There's a massive thread on winter tyres on the forum.  Might be summat of use in there?
