My wife has a F48 X1 Xdrive. I believe it's normally front wheel drive unless the car senses extra grip is required by driving the rear wheels.

Front tyres are down at 3mm and rears at around 5-6mm, and one of the rears has a big screw in the tread causing a very very slow deflation (over 6 weeks before the check tyre warning appears).

New runflats ordered, as preferred by the wife. Many motorways in the UK have lost their hard shoulder (emergency lane) and we've seen a couple of cars with flat tyres attempting to limp to the refuge area or the exit of the motorway.

If the car is mainly front wheel drive and has a transfer case, then does it make sense to rotate front tyres to rear every 6k miles, which should allow for even wear and avoid any issue with the transfer case? I think it does, and find it strange that BMW produces a car that is mainly front wheel drive fitted with a transfer case. The front tyres will wear more quickly than the rears and potentially impact the transfer case.

I also believe that the "newest" tyres should be on the rear to provide greater control and reduce oversteer. If I rotate then the ones on the rear may have a little more tread but I don't think it will be significant.

Thoughts? Thank you?

You need take into consideration the BMW requirements regarding tyres on XDrive models. This includes ( from memory and approx ) all tyres being same manufacturer and type , no more than 2mm tread depth between any tyres , all tyres have BMW star marking, do not mix RoF with normal tyres. I can not recall other points. Also different manufacturers have different rules on repairs on RoF tyres.

Regarding swapping corner to corner I have never done that. With my Z3 fun car it would be interesting with a staggered set up.

Generally speaking, BMW doesn't recommend rotating the wheels. But I do it anyway, to wear them evenly.

Mine X1 is sDrive, and I do rotate them following this:

With an FWD vehicle, move the rear tires to the front and flip sides. For example, the rear right tire will go on the front left. When you move the front tires back, keep them on the same sides.

I would say the same applies to xDrive with a square setup (like the x1), as long as the tread depth difference is not too much.

There are some videos here and there showing this procedure:

Thanks Abh29 and jrveron,

If I'd know the X drive models had so many specific tyre depth requirements that are not documented by BMW then we would have thought twice about buying the vehicle.

I wasn't aware the some RoF could be repaired. In my case, the screw in the Bridgestone may have been repairable according to google https://www.bushtyres.co.uk/tyre-new...un-flat-tyres/ , but then finding a local repair shop that will do the work would be another challenge.

I'll swap the new Contis every 6K or so to achieve even wear.

Thanks again

I am in the same situation. I decided to get 4 new tyres and rotate every 6,000 miles or so. Which tyres did you order by the way?
