TIRE AND WHEEL GUIDE
WHEELS
Usable Diameters: 13" to 15"
The table below is organized similar to a flow chart. It is broken down into different sections, depending on what Brakes and what Suspension you are using. Just find the setup relevant to your combination and go from there. Wheels are typical marked like “14x6 +38”, which means it is 14” diameter, 6” wide, and has an offset of +38mm. “ET38” is also a common way to write “offset of +38 mm”
The following assumes you are using either Stock brakes (4x114.3 PCD), or Aspire Rears (4x100), and using only suggested tire sizes. Aspire rear drums act like +10mm spacers, regardless of what rear beam you are using. If you are using Festiva rear drums that have been re-drilled to 4x100, please use the 4x114,3 section of the guide to determine the appropriate offsets.
| Suspension type | Brakes | Max Width | Offset Range |
| Stock Suspension | Stock (4x114.3) | 6" | +25 to +38 mm |
| Stock Suspension | Aspire rear (4x100) | 6" | +35 to +45 mm * |
| Coilovers with -3.5° Camber | Stock (4x114.3) | 7" | +25 |
| Coilovers with -3.5° Camber | Aspire rear (4x100) | 7" | +35 mm * |
Coilovers also assumes rolled fenders (fitting a 7” wheel in a festiva requires work and pretty precise fitment). If you do not have the rear camber, add a few mm to your wheel offset. You may also be able to go down to a +20 depending on how pulled your fenders are, and how low you are.
Centerbore:
Festiva: 59.1 mm
Aspire: 54.1 mm
Stock wheel sizes, for reference:
Base model L steelies 12 x 4 +40mm
L+ and LX steelies 12 x 4.5 +40mm
GL and LX alloys 12 x 4.5 +40mm
TIRES
Tires are listed like this: “165/55R14”
Where 165 is the width of the tire, in mm
55 is the aspect ratio of the sidewall. This is not in mm! This is a percentage of the width!
A little confusing. In this example, it means the sidewall height is 55% of the width 165.
14 is the diameter of the wheel in inches.
12" Tires:
145/80R12 (L Stock size)
165/70R12 (L+, LX. GL Stock size)
155/80R12 is taller, but usually cheaper and more common if you are in a pinch.
13" Tires:
155/65R13
165/60R13
165/65R13
185/60R13 (This is a size you can use for stickies on the track/AutoX)
14" Tire:
165/55R14
15" Tire:
165/50R15
Going 185+ wide for a daily/street festiva is not a great idea. Wider tires hydroplane much quicker with how light these cars are.
