1999 Dodge Grand Caravan Wheel Interchange

1999 Dodge Grand Caravan Wheel Interchange Guide - wheelinterchange.com

Known OEM Fitment For 1999 Dodge Grand Caravan

The values below are what we have on record for this model year. Some trims had different wheel and tire packages. If anything on your van differs, confirm against your door-jamb tire placard, the owner manual, or by measuring, then use the on-page calculator to compare.

Note: The presence of a 15x6 wheel and a 205/75R14 tire in the same dataset suggests multiple OEM packages existed for 1999. Always match tire diameter and rim diameter correctly and verify what your specific trim shipped with.

How To Use The Wheel Interchange Calculator

The calculator lets you compare a potential donor wheel or a custom size against your 1999 Grand Caravan so you can predict clearances and speedometer change before you buy.

• Step 1 - In Wheels from (donor vehicle), enter the wheel specs you want to try. You can also type in a custom wheel size and tire size.
• Step 2 - In Installed on (your vehicle), select 1999 Dodge Grand Caravan or manually enter the known OEM specs listed above.
• Step 3 - Adjust Custom wheel size: rim diameter, width, and offset. Offset affects inner clearance to the strut and outer poke toward the fender.
• Step 4 - Adjust Custom tire size: section width and aspect ratio. When you change rim diameter, the calculator updates overall tire diameter in the comparison.
• Step 5 - Review results: inner clearance change, outer poke change, and overall tire diameter difference. Inspect brake caliper clearance and strut clearance predictions.
• Step 6 - Aim to keep overall tire diameter close to your OEM tire diameter. As a general practice, try to stay within about 3 percent to help preserve ABS and speedometer accuracy.
• Step 7 - If anything is unclear, confirm with physical measurements and your OEM documentation before purchasing.

Fitment Checklist Before You Buy

• Bolt pattern must be exactly 5x114.3. Do not attempt to fit 5x115 or other patterns.
• Center bore must be 71.5 mm or larger. If larger, use hub-centric rings to 71.5 mm. If smaller, the wheel will not seat.
• Thread size is M12 x 1.5. Match the thread and the lug seat style to the wheel design.
• Offset and width must clear brakes, struts, and fenders. Use the calculator to compare against the OEM ET 40 mm and 6.0 in width.
• Overall tire diameter should closely match the size shown on your door-jamb tire placard. Use the calculator to estimate speedometer change.
• Verify brake caliper and spoke clearance, especially with smaller offsets or different spoke designs.
• Confirm load ratings on wheels and tires meet or exceed the vehicle requirement printed on the tire placard.
• Check lug nut engagement. As a rule of thumb, achieve at least one full stud diameter of thread engagement on each M12 stud.
• If using spacers, confirm hub-centric fitment and fastener length. Spacers change effective offset and may not be legal in all areas.
• Perform a test fit. Turn lock-to-lock and compress the suspension to check for contact before driving.

Plus Sizing And Common Upgrades

Owners often explore plus sizing for tire selection or appearance. Because OEM packages varied in 1999, do not assume a particular upgrade will fit every trim. Use the calculator to model changes:

• Plus 1 or Plus 2 wheel diameter - Increase rim diameter while selecting a tire with a lower aspect ratio so total tire diameter stays close to stock.
• Wider wheels and tires - Small width increases can improve grip, but verify inner clearance to the strut and outer fender poke with the calculator.
• Offset tuning - Keeping offset near OEM helps preserve scrub radius and clearance. Small changes can be workable if clearances remain safe.

If your door-jamb tire placard lists a different OEM size than the values above, use that placard size as your baseline for plus sizing.

Installation Tips

• Inspect and clean the hub face. Remove rust so the wheel sits flush. A light film of anti-seize on the hub face can help prevent future sticking. Do not lubricate wheel studs.
• Verify lug seat type and hand start all lug nuts. Do not use an impact gun to start threads.
• Snug lugs in a star pattern, lower the vehicle, then torque to the OEM specification found in your owner manual or service manual.
• If using hub-centric rings, seat them fully on the wheel before mounting.
• Re-torque after 50 to 100 miles of driving.
• After significant wheel or tire changes, have the alignment checked.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• 1/2 inch breaker bar
• M12x1.5 lug nuts - match seat type
• 71.5 mm hub-centric rings

FAQs

• What is the bolt pattern on the 1999 Dodge Grand Caravan?

  5x114.3. That is 5 studs on a 114.3 mm pitch circle diameter. Only use wheels that exactly match 5x114.3.

• What center bore do I need?

  71.5 mm. Wheels with a larger bore can be used with 71.5 mm hub-centric rings. Smaller bore wheels will not fit the hub.

• What is the OEM offset?

  ET 40 mm is recorded for this model year. Stay close to OEM and use the calculator to confirm inner and outer clearances for any change.

• What is the thread size for lug nuts?

  M12 x 1.5. Match the seat style to the wheel. Torque to the value specified in the owner or service manual.

• What tire size came stock?

  We have a record of 205/75R14 for some trims and a 15x6 wheel specification also appears in the data. This indicates multiple OEM packages in 1999. Check your door-jamb tire placard for the correct baseline.

• Can I run 16 inch or 17 inch wheels?

  Possibly, depending on tire size and clearances. Use the calculator to keep overall diameter near stock and verify inner and outer clearances. Always confirm brake and strut clearance with a test fit.

• Can I use 5x115 wheels on a 5x114.3 hub?

  No. Do not attempt to force-fit a mismatched bolt pattern. Use only exact 5x114.3 wheels.

• Do I need hub-centric rings?

  If your aftermarket wheel has a larger bore than 71.5 mm, hub-centric rings are recommended to center the wheel and reduce vibration.

• Why does backspacing not match my calculations?

  Backspacing can be published using different measurement points, such as to the rim flange or bead seat. If it is critical for brake clearance, measure your wheel directly and confirm with the calculator comparison.
