While a 225/75R16 is slightly narrower than a 235 tire, other factors are crucial:
* Wheel well clearance: The 225 might fit width-wise, but could rub against the wheel well (fender) depending on the van's design and suspension.
* Rim width: The 225/75R16 tire needs a rim width that's compatible with it; the van's rims might not be compatible.
* Sidewall height: The 75 aspect ratio (75% of the tread width) determines the overall diameter of the tire. A different diameter tire could affect the speedometer and odometer readings, and potentially interfere with the ABS and traction control systems.
* Spare tire compatibility: If you're considering this as a replacement for a spare, the spare's rim may not be compatible.
Always check your van's owner's manual. This is the only reliable source for determining the correct tire sizes. Incorrect tires can affect handling, safety, and void your warranty.
