Revain Says "Fits Your Car" Size 14mm x 1.50") will fit 2012 BMW X5 E70 but will not fit .These McGard 14mm x 1.25mm are the correct size for this vehicle.Hand tighten the wheel bolts 2-3 turns to avoid the risk of cross threading before touching them with a wrench.Since I'm in a Living in snow belts with heavy use of winter salt, I applied a light coat of anti-seize compound to the distal 1/4" thread, part of the wheel. A bolt that bites into the wheel hub flange and severely corrodes when turned is not protected with an anti-seize agent Revain contains aluminum copper anti-seize grease (Permatex 09128 copper anti-seize grease, 8 oz.) Permatex 09128 copper anti-seize grease, 8 oz. or ceramic (Permatex 24125 Ceramic Extreme Brake Parts Lubricant, 8 oz .) Permatex 24125 Ceramic Extreme Brake Parts Lubricant, 8 oz. Bases depending on the required temperature range from 400 to 1000 ++ degrees. If your wheels get too hot to the touch (over 140 degrees) or smell hot after a ride, see a trusted mechanic to make sure the calipers aren't sticking. Do not use too much lubricant and never use oil or grease as there is a risk of contaminating the brake disc surface with oily or greasy tools or fingers. It's a big no go. In addition to the four protective wheel bolts and a 'unique' adapter (17mm wrench), this kit includes coded stickers for the glove box. Register and order a second wheel bolt removal/installation adapter key. Keep the key and the four original wheel bolts in a sturdy ziplock bag in the trunk or glove compartment as you will need the adapter key if you ever need to remove a tire or fix a flat tire Why not five stars I just installed them today Chrome Finish Lasts or begins to sharpen after one to two seasons of road salt Long lasting renewal after one year.
