ULTIMATE GUIDE: WHEEL & TYRE CORRESPONDENCE TABLE

Which Tyre Width per Wheel (J-value) Do I Need?

When you buy new alloy wheels or tyres, it is crucial to determine the correct tyre width per wheel. A tyre must not be too narrow, but also not too wide for the wheel. This is important not only for a clean, sporty look (fitment), but above all for your safety and to preserve driving characteristics.

To help you find the perfect setup, Wheels 'N Customs has compiled the most comprehensive correspondence table in the industry. Where standard tables stop at 12 Inch (12J), our table goes up to extreme widths of 14J, specially for tuning and custom widebody projects!

Recommended vs. Tyre Stretch (Tuning)

When you search online for a wheel and tyre size table, it is important to know that in practice several “styles” are possible:

1. The Recommended Size

If you choose the tyre from the middle (red) column, the tyre sidewall will sit perfectly square and safely on the wheel rim. This offers the most comfort and protects the rim optimally against kerb damage.

2. Minimum Size (Stretch)

Very popular in the Stance/Tuning scene. By fitting a narrow tyre on a wide wheel, the tyre sidewall pulls inwards at an angle ("Tyre Stretch"). This causes the tyre to rub less in the wheelarch.

3. Maximum Size (Bulky)

Ideal for circuit use or 4x4 Off-Road applications (such as Fuel Off-Road wheels). The tyre bulges slightly over the rim in a balloon shape. This gives maximum contact patch and huge grip.
