ALLOY WHEEL FITMENT GUIDE

Thought it might be a good idea to try and give everybody looking to buy alloy wheels information about the different PCD's and offsets for different cars.

Alloys wheels can be excellent value on ebay and a huge saving over the new price, however there are lots of pitfalls and hidden sizes jargen etc you'd never think of until its too late and they don't fit properly, that is usually why a lot of people buy new wheels from shops/suppliers to ensure perfect fitment but with the information below you shouldn't go far wrong.

There are three main things to check and ask the seller when buying alloys, a lot of sellers may not put this information on as it can be very confusing or may not even know it as their wheels are sold to fit a specific car when bought new so the shop only would know the sizes.

please be aware this is only outlining what can be found in various proffesional textbooks, mechanics shops etc, but I will explain the general concept below.

1. firstly how many studs 4 or 5 studs bolts or stud holes, that hold wheels on and there are 2  main sizes 108 pcd and 100 pcd (pcd is pitch circle diameter the diameter of the stud holes) most cars are 100 pcd but some are 108 pcd (fords and peugeots) Some cars have other rarer pcds i.e 112 audi a4, 98 fiats and so on, as long as the pcd is correct they will fit even if the offset is well off which is how some sellers will say they fit but may not drive well on car at all.

2.The offset this is very important each manufacturer has a different offset measurement. The offset is basicly the distance from the hub of wheel to the mounting point of the hub surface on car, the smaller the offset the more the wheels will pertrude into the arches the bigger the offset the more the will intrude and possibly rub on the suspension mountings and brakes lines. Lets say you fitted a 45 offset to a 20 offset car, very confusing I know its not just a case of fitting any wheel to any car as i learnt the hard way when I was starting out, if the offsets is incorrect you can mess up the tracking geometery, and it may cause the car to tramline on cambered roads, handling badly and moving a lot in crosswinds, and sometimes shaking and flexing through the car and steering rack. If you stay close to manufacturers recommendations you should be fine

3. If the alloys are bigger than standard it can put the speedo rating out and cause an awful ride (fidgety very bumpy) and strange handling if you go too big i.e over 17's on a small car i.e saxo, but if you keep the size to the original manufacturers wheel size then it sould be fine, this is known as rolling radius the time it takes for the wheel to do a revolution the distance from centre of  wheel to outer of tyre

Example : As long as your tyres are lower profile each time you increase size of rim over standard it will still be the same size or similar within 2 inches as your original wheel and tyres, lets say a 15 inch wheel has a profile of 60 if you go up to 16 inch the profile will go down to 50 or 45 then  for 17 inch 40 or 45 and 18 40 35 and so on. (please be aware the lower the profile the harsher the ride will get usually 50 profile is the best compromise) but thats the pay off for better handling and having biggers wheels and better looks.

I will also explain what the measurement on the tyre sidewalls mean, you will probably know anyway but I thought I'd better list it anyway

eg 195/45 r 16 80v

195 means width ot tyre in mm

45 this is aspect ratio or profile of the tyre or sidewall height to relation to tyre width expressed as a percentage in this case 45% so 45% of 195mm == 88mm or height of sidewall from edge of the locating bead to top of tread

r radial

16 wheel diameter in inches

80 load index (lbs)

v speed rating

speed ratings

t up to 118 mph

h up to 130 mph

v up to150 mph

y up to 186mph etc etc

you can see even on similar models and within a brand sizes can vary a lot, it is easy to buy wrong sizes hence wheels usually go cheap second hand, even on the same manufacturers make of wheels, i.e  for example all toyotas won't necesserarly fit all toyotas they can vary in pcd and offsets,
