*Approved tyres

[Xrrbiggy]

What is the in and out with * approved tyres? I've read that a lot of people advise getting them but what's the real benefit? Is it just a sales deal between BMW and suppliers?

ive been mixing * and non * diamaris on my e53 for years. never had any problems. as long as tread depths are all similar you should be ok.

That's what I was thinking as at the end of the day it's just rubber but was intrested in people's opinions and thoughts on the matter

It is normally best to stick with * rated tyres as these match the performance of the car , unfortunately people see BMW as a premium brand , parts are premium , quality very good , then want to put cheap tyres on ! I seen a performance car the other day with budget  tyres with a low speed rating accident waiting to happen .
  In these days of insurance premiums going up the last thing you want after having a bump or accident is for them to say you had the wrong tyres on for the car for the few quid you save is it worth it ?

Marketing cowpoo.  But a star rated tyre will be from a decent manufacturer.  Why people buy a BMW and then put the cheapest bit of rubber on all four corners is beyond me. Same for servicing and general upkeep of the vehicle.
Stick with 4 tyres from the same manufacturer and same amount of tread and you won't go far wrong on any 4 x 4 BMW

What he said ^  (apart from the marketing bit).

The critical bit is tread depth variation front/rear.  Don't use off-road tyres, and don't go to the cheap end of the market - you need to have faith that 2-tonnes will stop if you need it too!

Change all corners as a set.  If you have 8mm at the back, and 3mm at the front you will break something.

Thanks for all the input live always change front and backs on previous two wheel drive cars and have read a lot about changing all four corners which I will do
