The wheel and tyre Bible everything you need to know about how to read your tyres tires and wheels with more info on rim sizes, tread depth and wear, aquaplaning, wheel balancing, aftermarket wheels, alloys, TPMS tire pressure monitoring systems and much more. Wheel dimensions. Okay. If you want to change the wheels on your car, you need to take. Number of bolts or studs. Os X Mountain Lion Utorrent For Mac. It goes without saying that you cant fit a 4 bolt wheel onto a 5 bolt wheel hub. Sounds obvious, but people have been known to fork out for an expensive set of alloy wheels only to find theyve got the wrong number of mounting holes. Pitch Circle Diameter. Right. So you know how many holes there are. Now you need to know the PCD, or Pitch Circle Diameter. This is the diameter of the invisible circle formed by scribing a circle that passes through the centre point of each mounting hole red in the image here. If youve got the right number of holes, but theyre the wrong spacing, again the wheel just wont fit. PCD notation. Stud patterns and PCD values are typically listed in this notation 5x. This means a 5 bolt pattern on an imaginary circle of 1. Pcd Calculator Software' title='Pcd Calculator Software' />Centre spigot size. This is a tricky one. There are two types of axlewheel design hub centric and lug centric. For hub centric designs, the wheel is centred using the spigot before the wheel nuts or lug bolts are tightened. In this design the spigot normally sticks out from the axle of the car which is why it can be used to centre the wheel beforehand. With aftermarket alloy wheels, the spigot hole is often larger than the spigot on the car which is why you need a spigot locating or hub centric ring. This is a plastic or metal doughnut that matches the outside diameter of the wheels spigot hole and the inside diameter of the axle spigot, and is used to ensure a snug fit between the two whilst centring the wheel. For lug centric designs, the wheel is centred during the process of tightening the lug nuts, often because the axle spigot does not stick out either at all, or far enough to be any use in centring the wheel. Inset or outset. This is very important. Ignore this and you can end up with all manner of nasty problems. This is the distance in mm between the centre line of the wheel rim, and the line through the fixing face. You can have inset, outset or neither. This determines how the suspension and self centring steering behave. The most obvious problem that will occur if you get it wrong is that the steering will either become so heavy that you cant turn the car, or so light that you need to spend all your time keeping the bugger in a straight line. More mundane problems through ignoring this measurement can range from wheels that foul parts of the bodywork or suspension, to high speed judder in the steering because the suspension setup cant handle that particular type of wheel. This figure will be stamped on the wheel somewhere as an ET figure. Inset and outset are subsets of offset and the relationship is this positive offset inset. Negative offset outset. Typically you can get away with 5mm 7mm difference from the vehicle manufacturer specification before youll run into trouble with the wheels fouling the suspension or bodywork. So for example if your stock wheels have an offset of 4. OK. More inset closer to the suspensionIt may sound counterintuitive, but when you increase the inset of a wheel, you decrease the clearance between the inner edge of the wheel and the suspension components. In the example here, the red wheel has a larger inset ie. The grey blocks indicate a stylised mounting hub, axle and suspension component. You can see that by increasing the inset positive offset of the wheel, it pushes the inner edge of the wheel and tyre closer to the suspension. Conversely, decreasing the inset moves the wheel and tyre closer to the outside of the vehicle where it might scrub and rub against the bodywork and wheel arches. It might help to think of this more in terms of overall offset rather than inset and outset. The most positive the offset, the more the wheel is tucked into the car. The more negative the offset, the more the wheel sticks out. A real example. They say a picture is equivalent to a thousand words, so study this one carefully. Its one of the alloy wheels off one of my old cars. Enlarged so you can read it is the wheel information described above. Youll notice it reads 6. J x 1. 4 H2 ET4. The 6. J x 1. 4 part of that is the size of the wheel rim in this case it has a depth of 6 inches and a diameter of 1. The J symbolises the shape of the tyre bead profile. The H2 means that this wheel rim is a double hump design see hump profiles, below. The ET4. 5 figure below that though symbolises that these wheels have a positive offset of 4. In other words, they have an inset of 4. In my case, the info is all stamped on the outside face of the wheel which made it nice and easy to photograph and explain for you. On most aftermarket wheels, they dont want to pollute the lines and style of the outside of the wheel with stamped on information its more likely to be found inside the rim, or on one of the inner mounting surfaces. Trivia note ET comes from Einpresstiefe in German rim offset actually inset, literally. The wheel offset calculator. This little javascript will help you to understand the different between your old and new wheel and tyre combination in terms of the offset and how its going to affect the overall lateral position of the wheel and tyre. Technically you can do this calculation with either the wheel width in inches or the tyre section in mm. I chose to use the tyre section instead of the wheel width because in almost every case, the tyre extends beyond the wheel rim so its the widest part of the wheel and tyre combo. So whilst calculating the clearance just with the wheel might show no interference between the suspension or bodywork and the wheel, once a tyre is added, it could interfere as the tyre is wider. Matching your tyres to your wheels. Okay. This is a biggie so take a break, get a hot cup of Java, relax and then when you think youre ready to handle the complexities of tyre matching, carry on. This diagram should help you to figure out whats going on. Wheel sizes are expressed as WWWx. DDD sizes. For example 7x. A 7x. 14 wheel is has a rim width of 7 inches, and a rim diameter of 1. The width is usually below the width of the tyre for a good match. So a 1. 85mm tyre would usually be matched to a wheel which is 6 inches wide. Comment Installer Windows Vista Service Pack 1. Static loaded radius, outer diameter and rolling circumference. These three measurements are all important to consider when talking about wheels and tyres. Theyre all interlinked. Straight from the manufacturer, a tyre is circular and its outer diameter OD is based on this unladen, perfectly circular condition. Because tyres deform under load flatter on the bottom than they are on the top when taking the weight of a car, the vertical radius of a tyre under load is not half the diameter. Its typically about 4. In addition, a tyre doesnt roll like a solid wheel the steel or fabric belt rolls along the ground like a caterpillar tank tread does. Because of this, the rolling circumference of the tyre isnt quite what youd expect. The closest approximation for this value can be calculated by taking the outer diameter, subtracting twice the tread depth and multiplying by PI. Roughly speaking, thats 0.
