Rimsorizer

For people that don’t know anything about wheel definitions, we searched for some good information.
On the website of Enkei we did found some really good info that is very useful.

On the image below, you can see what they discuss on their website.
To make it a bit easier, we also posted their story on our website. Just to make it more accessible for the public.
What we explain is the tire size, wheels size, PCD, offset and the clearance.

Below you can see more info about wheel definitions:

Tire size:

1-Tire width (mm or inch)
2-Aspect ratio
3-Radial construction
4-Rim diameter
5-Load index
6-Speed symbol
7-Tire outer diameter (inch)
8-Ply rating

Wheel Size:

PCD:
The number of bolts used to install a wheel varies from 4 to 6 depending on the vehicle model (except for some vehicle types), thus the wheel to be installed should also possess the same number of hub bolt holes. P.C.D. stands for pitch circle diameter, and indicates the diameter of the circle in mm connecting the center of each hub bolt. Since the P.C.D. also varies according to the vehicle model, make sure a suitable one is selected.

Offset:
The offset indicates the distance from the center of the rim to the attaching disk part (unit:m/m). As seen in the attached drawing, the offset is indicated by “+” when the fitting surface extends beyond the central line of the rim and “-” when it is falls within. Caution is required to prevent the tire from coming into contact with the fender of the vehicle or the brake caliper if the offsets are very different.

Clearance:
Fender clearance indicates the marginal space between the tire and the fender or body of the vehicle. Inner clearance indicates the distance between the tire and wheel and the body part which is positioned closest to the tire and wheel. Dimensions for both right and left clearance should be measured on a level surface, and the smaller value is then considered as the inner clearance.
