* Bolt Pattern: 5x114.3mm (This is the most common and likely for your car)
* Offset: This varies considerably depending on the wheel option originally fitted. It's not a single number and you won't find a definitive answer without checking your existing wheels. Offsets typically range from +20mm to +40mm but could be outside of that range depending on the specific factory option or aftermarket wheels previously installed.
To find the correct offset for YOUR 1985 Toyota Supra, you should:
1. Check your existing wheels: The offset will be stamped on the back of the wheel itself. Look for a number preceded by a "+" or "-" sign.
2. Consult your owner's manual: If you have the original owner's manual, it might specify the factory wheel specifications.
3. Check a reputable online parts database: Websites selling Toyota parts will often have detailed specifications based on the vehicle identification number (VIN). You'll need your VIN to use this method.
Without knowing the exact trim level and checking your existing wheels, any offset provided would be purely speculative and potentially dangerous. Using the wrong offset can lead to rubbing and handling issues.
