Tips on How to Keep Your BMW 750i’s Tires Rolling
The BMW 750i uses run-flat tires: these are built with stiff sidewalls so that even when deflated it can support the car at 50 mph, just enough to get you to a repair shop. While this has been a breakthrough in technology aimed at completely eliminating the need for carrying a spare tire, it can be quite costly to keep replacing these tires if you don't take preventive measures against avoidable damage. So here are some ways on how to prolong the life of your tires.
- Get up to speed with the kind of tires you have.
There are two kinds of run-flat tires: self-supporting, and auxiliary supported. Self-Supporting tires have stiffer and tougher rubber, and this kind usually requires a tire pressure monitoring system. Auxiliary supported tires don't have stiffer and tougher rubber, but are attached to a special rim which has a steel support ring that is attached to the wheel and can support the weight of the vehicle. So take note of these facts because you don't want to overestimate the features of your car's tires by wearing them off. If your tire-pressure warning light on the dashboard is glowing, find a secure lay-by lane to check your wheels.
Your 750i weighs about 4000 lbs and run-flat tires are heavier than your conventional tires due to its reinforced sidewalls. So, the added weight can significantly contribute to the impact that your car endures when you accidentally drive over those pesky potholes. So if your car is already at full capacity, don't go overboard by filling up your boot with your entire collection of golf clubs.
- Practice cautious driving at all times.
The run-flat tires on your 750i are known to wear and tear after an average of 6,000 miles sooner than owners using standard tires. So stop treating potholes and manholes like checkpoints on the road that you MUST cross every time you pass by. They not only damage your car's wheels, they may also lead to an accident if your car loses traction (most especially on rainy days).
- Do not attempt a DIY on your wheels if you don't have the know-how.
The advanced engineering of your BMW's tires requires professional attention once it's damaged. Gone are the days when you can just seal the holes on your car's flat tire and go on with your trip to the repair shop where you'll get your car fixed in a jiffy. Service stations usually do not have a lot of run-flat tires in stock so you have to wait a few days for the shipment of a replacement. If your tires are punctured or blown out, the only option that you have is to get a new one.
- Think twice before getting replacement tires.
There seems to be more cons than pros with your 750i's run-flat tires so you just want to change to normal tires to avoid the future inconvenience of it all. Take note that this car was manufactured with this specific kind of tire, so you must also consider getting the right kind of wheels for the job. Don't forget the spare tire while you're at it.
