[quote=""CondorX5""]Winter Tyre and Rim recommendations: BMW OEM
I’ve made a summary of the official BMW recommended wheel and tyre combos for X5s as per their June 2010 Brochure……..
There are usually many posts about winter wheel issues over the Autumn / Winter months so this is an effort to keep all of them in one ongoing discussion thread so that info is easy to find and does not have to be repeated ad nauseum. The idea is that we maintain an open discussion on the subject of winter wheels which can be updated or added to as time goes on.
Please remember that these are just guidelines and do not represent an endorsement of what should or should not be done to your car – that is for you to decide alone or in consultation with a dealer / mechanic.
I am certainly not an expert in any matters pertaining to wheels and tyres and speak only as an owner/driver of an E53 X5 who has done some research on appropriate and safe winter driving.
I'll of course try to help with any queries, as will other technically more knowledgeable forum members, I am sure, and we'll build up the knowledge base in time.
Hope I’ve covered most of the most obvious questions!
E53 X5: models 3.0D, 3.0i (NOT the V8 models)
EDIT: 4.4 models apparently excluded - 17" rims fit as per Lez' post below. So all E53 models except 4.6is and 4.8is suitable for 17" wheels. Obviously if brake fitment has been modified with oversize Brembos etc, this will change things. All recommendations assume standard factory brakes.
I fitted oversized Brembo . need 20mm spacers to fit the space saver spare . 19 inch and 20 inch wheels clear the outer side of caliper by 1mm without spacer.
TYRES: 235/65R17
RIMS: Star Spoke 57
OFFSET ET40 7.5J X 17
E53 X5 4.4, 4.6 and 4.8 models (17†rims will NOT clear the brakes on 4.6 & 4.8 models)
TYRES: 255/55R18
RIMS: Star Spoke 99
OFFSET: ET40 8J X 18
Note that Runflats are NOT recommended for ANY E53 model.
Tyres recommended by BMW include Continental 4x4 Winter Contact in 17†fitment and Dunlop Grandtrek WTM2.
E70 MODELS:
Note that runflats are officially recommended for E70 models.
18†and 19†Combos are recommended for E70s:
18â€: Cross Spoke 177, OffsetET46 8.5J X 18, Tyres 255/55R18
19â€: Yspoke 211 , Offset ET48 9J X 19, Tyres 255/50R19
FREQUENTLY ASKED QUESTIONS:
1. Will other rims fit other than those mentioned above?
Yes, most OEM 17†rims will fit the diesel and 3.0i models, but worth checking if other members have any direct knowledge of the particular rim. For instance, the original Style 56 Ellipsoid rims fit and are usually sourced for a modest sum. Non-OEM rims and those from other vehicles such as Range Rovers are a minefield and best left to individuals to decide upon, so not included here.
2. Which make of tyre is the best?
We all have individual preferences, but dedicated winter tyres from any major manufacturer are suitable and price and availability will in some cases determine the choice. I and many others are great fans of Vredesteins, but there are winter tyres available from all major manufacturers all of which are suitable for purpose.
3. Can E70 wheels be bolted straight onto an E53 X5?
No. It is possible to use E70 wheels on an E53 but you will need the correct spacers.
4. When must I change to winter wheels?
Generally, when temperatures outdoors fall to around 7 degrees C consistently – winter tyres are a softer compound and perform at their best below 7 degrees C, although they are perfectly safe to leave on a vehicle at any time. It is said that the tyres will wear quicker in high temperatures and that “performance†will not be as good, although this has certainly not been everyone’s experience. Most people change wheels to winter sets around November and change back to summer sets again around April.
5. Can I stagger the fronts / rears to get a better “look�
Probably, although not recommended. The winter wheels are the same on all four corners – no staggered fitment. Some people have fitted rear spacers to give the appearance of staggered tyres, but this is up to the individual and not endorsed by the forum.
6. When should winter tyres be renewed?
Winter tyres should be changed when they get to 3-4mm depth, unlike summer rubber which can go to 2-3mm. Be aware of this if buying part-worn tyres – most sellers are optimistic about tread depth on these, and any tyres of 4mm or below will last at best for only a single season.
7. What about a spare wheel if a winter tyre is punctured / damaged?
Probably good practice to have a matching spare winter tyre available (I doubt most of us do) - the spare wheel in the car (for those who have a spare) can be used for a short period (up to 50 miles) to get the car to safety, but obviously winter and summer tyres should not be used on the same axle or the same car in combination at any time. Availability can mean no winter tyres available for months on end in winter, so even a part-worn “spare†winter tyre can be incredibly useful if you have the space to store one at home as chances are you would not be able to find a replacement in the middle of winter.[/quote][/quote]
What speed rating is required for x5's? I have seen some Wintrac 4 extreme but they are H - is this ok??
