Compatibility Decision Engine

Will it fit? Is it safe? Know before you buy.

Check compatibility for wheels, tires, engine swaps, lifts, and towing setups — with a structured verdict based on your exact vehicle, not generic forum advice.

What kind of decision are you facing?

Pick the situation closest to yours. Ownery will guide you toward a clear, vehicle-specific verdict.

You get a verdict — not a wall of text

Ownery doesn't give you articles to read. It gives you a structured decision with clear options, costs, risks, and a final recommendation.

Every verdict includes:

🎯

Likely options — what you can actually do, ranked by practicality

💰

Cost range — realistic price estimates for each option

⚠️

Risks — what could go wrong and how serious it is

📈

Effort / complexity — DIY feasibility, shop time, parts availability

Final verdict — a clear recommended action you can act on

Sample Decision — Wheel Fitment Check
Vehicle 2021 Toyota 4Runner TRD Pro
Question 285/70R17 on stock suspension
Bolt Pattern 6×139.7 — matches
Clearance Fits with no modifications
Risk None — OEM-compatible sizing
Allowed — direct fit on stock suspension. No rubbing, no trimming, no lift needed.

Allowed. Conditions apply. Not recommended.

Ownery gives you structured answers you can act on — not forum threads and "it depends."

✓ Allowed

"Will 265/70R17 tires fit my 4Runner?"

Yes — direct fit on stock suspension. No rubbing, no modifications needed.

⚠ Conditions Apply

"Can I run 33s on my Tacoma without a lift?"

Possible with trimming and 0-offset wheels, but rubbing likely at full lock. 2-inch lift recommended for safe clearance.

✗ Not Recommended

"Is a 3-inch lift safe with stock control arms?"

Not recommended — accelerates CV joint wear and worsens handling. Upgraded UCAs required for safe operation.

The kind of questions Ownery answers

Real scenarios from vehicle owners who were stuck researching — and needed a structured answer.

Engine Swap

Will a 2JZ engine swap work in my 1998 Toyota Tacoma?

Conditions apply — physically possible but requires custom mounts, ECU wiring, and won't pass emissions in some states. Budget $8k–15k.

Wheel Fitment

Can I run 285/70R17 on my stock Tacoma TRD?

Allowed — fits with minor trimming on TRD Off-Road. No lift needed, no rubbing at full lock after trim.

Towing

Can my 2020 F-150 3.5 EcoBoost tow a 9,000 lb RV?

Allowed — within max tow rating of 13,200 lbs with Max Tow Package. Ensure proper WDH and trailer brakes.

Lift Kit

Can I install a 6-inch lift on my daily-driven Wrangler?

Not recommended for daily use — affects stability, braking distance, and driveline angles. 2.5–3.5" is the practical max for DD.

Tire Sizing

Will 35-inch tires fit on my stock JL Rubicon?

Conditions apply — fits without lift but rubs at full lock. Minor fender trimming or bump stop extension needed.

Bolt Pattern

Can I use Ram 1500 wheels on my Tundra?

No — Ram uses 5×139.7, Tundra uses 5×150. Different bolt pattern, not interchangeable without adapters (not recommended).
