Spare tire (donut) limits: speed, distance and PSI

Jump to: Types of spares · Speed · Distance · PSI · Miles remaining · TPMS · When not to use · Vs full size

Short answer: a compact temporary spare (often called a donut) is built to get you to a shop, not to finish a road trip. Federal labeling for non-pneumatic spares requires MAXIMUM 80 KM/H (50 M.P.H.) and FOR TEMPORARY USE ONLY. Toyota and Ford owner manuals give the same 50 mph cap for temporary or dissimilar compact spares. AAA advises driving no more than 50 miles on a donut-type spare. Your sidewall and owner’s manual still win if they are stricter.

Temporary spare, compact spare, and full size spare

Type	What it is	Typical limits (verify yours)
Compact / T-type temporary (donut)	Narrower and often taller pressure; labeled temporary use	Often 50 mph; short distance only; many T-type tires labeled 60 psi
Dissimilar full size spare with temporary label	Looks closer to a road tire but marked temporary	Ford: do not exceed 50 mph; replace ASAP
Matching full size spare	Same size and type as the road tires	Usually driven more like a normal tire, still replace a damaged road tire promptly
Tire repair kit (no spare)	Sealant and compressor for some punctures	Follow the kit and manual; not the same as a spare

Limits vary by vehicle and tire. The table is a map of common patterns, not a substitute for your placard, sidewall, or manual.

How fast can you drive on a donut?

Usually 50 mph (80 km/h), and no faster.

• FMVSS No. 110 requires non-pneumatic spare tires or assemblies to be permanently marked FOR TEMPORARY USE ONLY and MAXIMUM 80 KM/H (50 M.P.H.).
• NHTSA interpretation nht81-2.27 discusses a temporary use spare labeled MAX. SPEED 50 MPH (and notes temporary spares are exempt from UTQG).
• Toyota owner manuals (for example Tacoma, Prius, Sequoia, Yaris) warn: do not drive in excess of 50 mph (80 km/h) with a temporary or compact spare installed.
• Ford owner manuals warn that with a dissimilar spare wheel and tire (including temporary use assemblies), you must not exceed 50 mph (80 km/h).

If your sidewall or manual prints a lower limit, use that. A smaller diameter spare can also make the speedometer read high or low, so treat the posted limit as a hard ceiling, not a target.

How far can you drive on a temporary spare?

As short a trip as you can manage. There is no single federal distance number that applies to every temporary spare.

• Many OEM manuals say replace the temporary spare with a standard road tire as soon as possible, without publishing a fixed mile cap (Toyota language is typical).
• AAA states you should not drive over 50 mph and no more than 50 miles with a donut-type spare.
• Some sidewall labels or manuals publish a different distance. Always follow the lower of the sidewall, placard note, and owner’s manual.

Do not invent a longer “safe” trip because traffic is light. Temporary spares have less tread life, different grip, and can stress driveline and brake systems when the rolling diameter does not match the other three tires.

What PSI should the spare be?

Use the pressure on the spare sidewall and any spare line on the door placard, not the cold PSI you set on the four road tires.

• Under FMVSS No. 109, a T-type spare with a maximum inflation pressure of 420 kPa (60 psi) must be molded with the words Inflate to 420 kPa (60 psi) on both sidewalls.
• Tire makers such as Toyo note about 60 psi for many “T” type high pressure temporary spares, and a different value for temporary full size spares. Always read your tire.
• Check the spare cold with a gauge before you need it. A flat spare in the trunk helps no one. See our cold tire pressure guide.

Miles remaining on the spare (rough check)

Enter how many miles you have already driven on the temporary spare, and the maximum distance your sidewall or manual allows. If your manual only says “as soon as possible,” use AAA’s 50 mile donut guidance as a conservative planning number, then still head to a shop. This runs in your browser and stores nothing.

Miles already driven on the spare

Max miles from sidewall or manual

Planning aid only. Sidewall and owner’s manual limits override this form. If either says replace sooner, replace sooner.

TPMS and the spare

Many compact spares do not carry a TPMS sensor. Ford notes that the TPMS indicator light illuminates when the spare tire is in use, and that full monitoring returns only when all road wheels with sensors are mounted again. Treat a light with a spare fitted as expected until the road tire is back, then recheck pressures with a gauge. More detail: TPMS warning light guide.

When not to use a donut (or when to be extra careful)

• More than one temporary spare at a time: Toyota and Ford both warn against using more than one temporary or dissimilar spare simultaneously.
• Towing or heavy loads: Ford says do not tow a trailer and do not exceed the maximum vehicle load rating on the Safety Compliance label while on a dissimilar spare.
• Snow chains: Ford says do not use snow chains on the end of the vehicle with the dissimilar spare. Toyo and Toyota also warn that chains will not fit or can damage a temporary spare.
• AWD / 4WD systems: Ford warns that a dissimilar spare can impair all-wheel driving capability. Toyota warns that 4WD or E-Four systems may not operate correctly and may negatively affect drivetrain components. Follow the manual; prefer the shortest safe trip to a shop.
• High speed, rough roads, car washes: lower ground clearance and thinner tread make obstacles and automatic car washes risky (Toyota and Ford both flag car wash and clearance concerns for temporary or dissimilar spares).
• As a long term fifth tire: temporary spares are not designed for continuous use. Age still matters; check the DOT date. See how long tires last and the DOT date code decoder.

Temporary spare vs full size spare

A matching full size spare (same size and type as the road tires) generally restores more normal handling and does not carry the same 50 mph temporary label. A dissimilar full size spare may still have limits: Ford caps some labeled temporary full size assemblies at 50 mph, and some unlabeled dissimilar full size spares at 70 mph, with other restrictions (no snow chains on that end, no more than one dissimilar spare). Either way, repair or replace the damaged road tire promptly. If you are replacing only two tires later, read mixing tires / replace 2 or 4 and when to replace tires.

No spare? Tire repair kits

Some newer cars ship a sealant and compressor kit instead of a spare. That kit is for temporary puncture sealing of a road tire, not a free pass to ignore speed and distance limits printed with the kit. For what counts as a proper permanent fix afterward, see tire plug vs patch. Honda’s 14 Oct 2026 multi-model recall (NHTSA related campaign coverage of repair kit nozzle and bottle cap pressure, Honda newsroom release for 2023 to 2026 Accord Hybrid and CR-V Hybrid models among others) is about the repair kit, not a spare tire. Check your VIN on NHTSA recalls if you own an affected model.

Quick checklist after a flat

1. Pull to a safe place, hazards on, parking brake set.
2. Confirm the spare is inflated to its own labeled PSI.
3. Fit the spare per the owner’s manual jack points.
4. Drive at or under 50 mph (or the lower labeled limit).
5. Go straight to a shop for repair or replacement of the road tire.
6. After the road tire is back, recheck all four pressures cold and confirm the TPMS light clears.
