Fittings & Accessories Explained
What makes up the FREE fitting kit we supply with every set of wheels?
The FREE fitting kit we supply with each set of wheels includes brand new wheel bolts or nuts, dependant on vehicle specification, a set of anti-theft locking wheel bolts or nuts, and 4 Spigot rings (if required and explained below).
Nuts or Bolts: Whats the difference between wheel bolts and nuts?
If the vehicle has studs coming out of the hub, you will use a nut to fasten the wheel to the vehicle. Vehicles without studs will use a bolt to fasten the wheel to the hub of the vehicle. Bolts and nuts have various diameters, threads and seating, and our sales team will ensure the correct fitting kit is provided for your car with every wheel or wheel and tyre package.
The thread diameter refers to the diameter of the stud, measured across the shank at the outer edges of the thread e.g. 12mm. The thread pitch is the number derived at when dividing the number of threads in 10mm into 10 e.g. 8 threads along 10mm has a pitch of 1.25.
NOTE: It is extremely important that the nut or bolt seat properly in the wheel bolt hole. Most wheels use a tapered nut or bolt (usually with a 60º taper). Some wheels, especially Mercedes’ wheels use a radius taper bolt. Our team will ensure correct fitment for you.
Spigot Rings
Made from either plastic or metal, these allow perfect fitment and alignment of your alloy wheels when the centre bore differs from the hub lip diameter. A spigot ring is fitted into the back of the wheel with an outer diameter the size of the centre bore, and an inner diameter the size of the hub lip to allow the wheel to be correctly located onto the hub and to fit tightly onto the vehicle for safety and comfort. Only supplied if necessary.
Wheel Spacers
If the offset of a wheel is too high for your vehicle, in most cases spacers can be used to reduce the offset, pushing the wheel further out to make it sit correctly in relation to the cars bodywork and arches.
They allow you to fit wheels to your car that aren’t initially made in a direct fit, widening your choice of wheels and are completely safe and road legal to do. Spacers can also be used in cases where your wheels already fit your car but you just want them to sit out just that little bit wider, maybe give the car a wider rear stance.
Locking Nuts/Bolts
These are now included FREE of charge with EVERY wheel and tyre package bought from Rimstyle (normally £19.00). They are an essential accessory to keep your new wheels safe from theft.
With each kit you receive 4 locking nuts or bolts, whichever is relevant to your cars fitment, and a key to lock them on to the car. You simply tighten one into each wheel in place of one of the standard nuts/bolts to lock the wheels on to your car. Great at preventing fraud and deterring thieves!
