Hi
@Hussainahmdd - I’m might be misunderstanding your post but assuming I’m not, I'm struggling to understand how
just one of the five bolts didn’t line up with the bolt hole in your car’s wheel hub assembly. If the Bola alloys are 5x112 then all bolt holes in the alloys should line up exactly with the bolt holes in your car’s wheel hub. If the PCD is anything other than 5x112 then you‘d probably only be able to get the first bolt to fit correctly.
With any alloy wheels I’ve had - either the OEM originals fitted to the car or aftermarket alloys I’ve bought - the spec of the wheels (the ‘J’ size, diameter, offset, PCD / bolt pattern, centre bore size etc.) has been cast into the reverse side of the spokes. Assuming Bola do this with their alloys, then the PCD / bolt pattern (5x112 if that’s what yours actually are) should be one of the spec details cast into the back of the spokes. Checking the reverse of the spokes should hopefully confirm whether or not they are the correct fitment for your car.
Most aftermarket alloys do have ‘oversized’ centre bores - this is to maximise the number of vehicle makes that the wheels can be fitted to, so maximises alloy wheel sales for the wheel’s manufacturers. As has been said, spigot rings of the appropriate size will reduce the centre bore size of the Bola’s down to 57.1 (the centre bore size for most VAG cars) and will
help to centre the wheel on the wheel hub when mounting the wheels on the car. Spigot rings may also
help minimise or eliminate any potential wheel wobble / vibration that might be present if spigot rings aren’t used, although wheel bolt tightening sequence is also important in this respect - see below. However, spigot rings won’t solve the issue of misalignment of the bolt holes in the wheels with those in the wheel hubs if the PCD of the wheels is something other than 5x112.
A few other important points to note;
- Most aftermarket alloys use bolts with a conical seat and OEM alloys use bolts with a radius / ball seat. It’s important to use the correct bolts where the profile of the bolt seat matches the profile of the bolt holes in the wheels. Use of the correct bolts when torqued to the manufacturer’s torque spec should ensure the correct clamping force is achieved between wheel and hub, prevent undue stress being exerted on the wheel bolts and stop the wheels working loose while driving.
- Bolts should be tightened in a star pattern to minimise the risk of vibration. When the car is jacked up to fit the alloys, the bolts should initially be hand tightened (in a star pattern). When the car is lowered to the ground, the bolts should then tightened to the car manufacturers torque setting in the same star sequence - as per the picture below;

- Fitting different alloys to those fitted by Seat when the car was built is a modification for insurance purposes, so it’s important to inform your insurer; not doing so could invalidate your insurance cover.
