What Is 34″ V2?
34″ V2 — For Wider, Bulkier Spare Tires
34″ V2 is for spare tires that measure approximately 34 inches but have thicker sidewalls or deeper tread.
Choose 34″ V2 if:
- Your tire diameter is close to 34 inches
- Your tire looks wider or bulkier than a standard road tire
- You have an off-road, all-terrain, or mud-terrain tire
⚠️ When in doubt between 34″ and 34″ V2, choose 34″ V2 — a slightly looser fit is better than a cover that won’t close.
Add-on option
Do You Need the Camera Hole Option?
No Camera Hole
Camera is in bumper or tailgate — not on the spare tire.
- Most SUVs, RVs, trailers
- Jeep Wrangler JK (most trims)
- Ford Bronco (camera on bumper)
With Camera Hole
Backup camera is on the spare tire itself.
- Jeep Wrangler JL (Sahara, Rubicon)
- Some Jeep Gladiator models
⚠️ Not sure? Look at your spare tire — if you see a camera lens on it, choose With Camera Hole. Contact us if in doubt.
⚠️ Important Notes Before Ordering
- Sizes are based on tire outer diameter, not wheel/rim size
- When between two sizes, always go larger
- Incorrect size selection is not eligible for return or refund
- If unsure, contact us before ordering
