1991 Daihatsu Tire Fitment Guide

1991 Daihatsu vehicles covered here use three tire sizes: 145/80R13, 155/80R13, and 165/70R13, all on the Daihatsu Charade. Each of those sizes is a radial built for a 13-inch wheel, so the wheel diameter stays the same even though section width and profile vary. Rim-width guidance is available for 155/80R13 products, with examples spanning 4.00 to 5.50 inches depending on the tire.

That means a 1991 Daihatsu owner should confirm the exact Charade configuration first, then match the tire size to the wheel and the look of the car. A 13-inch wheel alone does not make all three sizes interchangeable in practice. The sidewall profile, section width, and approved rim-width range still matter when preserving the intended stance and ensuring the tire sits correctly on the wheel.

On a 1991 Daihatsu, 145/80R13 is a metric radial size. The 145 is the nominal section width in millimeters, 80 is the aspect ratio, the R identifies radial construction, and 13 is the wheel diameter in inches. It is one of the narrower Charade sizes used during the 1991 model year.

That coding matters because a 145/80R13 has a different width and sidewall height than the 155/80R13 and 165/70R13 alternatives, even though all three mount on 13-inch wheels. A buyer restoring a 1991 Daihatsu Charade or replacing worn tires should verify the original size used on the car rather than substituting by guesswork. The metric code gives you the basic dimensions, but actual fit still depends on the wheel and the specific Charade application.

No. Only one 1991 Daihatsu model is covered here, the Charade, but that single model uses three different tire sizes: 145/80R13, 155/80R13, and 165/70R13. All are 13-inch radials, yet they are not one-size-fits-all across the Charade range.

For a 1991 Daihatsu buyer, that means year and make are only the starting point. You still need to identify the exact Charade setup before choosing a tire, especially if the car has changed hands or has already had tire replacements over the years. Checking the existing verified size, wheel, and factory reference points is the best way to avoid choosing a tire that mounts on the wheel but changes the car’s proportions or fit unnecessarily.

A 1991 Daihatsu should use the tire size that matches the Charade’s actual application, not simply whichever 13-inch size is easiest to find. The three sizes all share radial construction and a 13-inch rim diameter, but they differ in section width and profile. Among them, 155/80R13 currently offers the broadest range of branded options and whitewall treatments.

That makes the decision mostly about correct fitment first and product selection second. If your 1991 Daihatsu Charade was built around 145/80R13 or 165/70R13, moving to 155/80R13 without checking clearance, rim width, and intended stance can change the way the car sits and responds. Treat the original size reference as your baseline, then compare available products within that exact size whenever possible.

1991 Daihatsu tire options in 155/80R13 include narrow whitewall and wide whitewall styles. Travelstar, Maxxis, and Tornel offer narrow whitewall versions in this size, while BFGoodrich offers a wide whitewall variation. All of them are radial tires built for 13-inch wheels.

On a 1991 Daihatsu Charade, sidewall style is mainly a visual decision rather than a fitment category by itself, but it still affects how period-themed or customized the car looks. A narrow whitewall usually feels more restrained on a small import, while a wide whitewall creates a more stylized appearance that leans away from factory economy-car presentation. Choosing the right look starts with confirming that 155/80R13 is the correct size for your Charade.

1991 Daihatsu vehicles currently have 155/80R13 tire coverage from Travelstar, BFGoodrich, Maxxis, and Tornel. Each of those choices is a radial, and together they span both narrow whitewall and wide whitewall appearances. The Travelstar version carries a 79T marking, while several others in the same size show a maximum load of 959 pounds at 35 psi.

Brand choice on a 1991 Daihatsu often comes down to the style you want and the wheel range your Charade uses. A buyer focused on a cleaner stock-style presentation may look at one whitewall width, while someone building a more personalized period look may prefer another. Once the correct size is confirmed, comparing sidewall appearance, rim-width compatibility, and any marked speed or load information will narrow the field quickly.

For 1991 Daihatsu applications in 155/80R13, rim-width recommendations vary by product. BFGoodrich pairs that size with a 4.00 to 5.50-inch rim-width range, Maxxis uses 4.50 to 5.50 inches, and Tornel uses 4.00 to 5.00 inches. All of those tires fit a 13-inch wheel diameter, but width approval is not identical from one tire to another.

That matters because two tires with the same 155/80R13 code can still have different wheel-width preferences. If your 1991 Daihatsu Charade is still on original wheels, measure or verify the wheel width before choosing among brands. Staying inside the approved rim-width range helps preserve sidewall shape and keeps the tire operating as intended, especially on a lightweight car where a small dimensional change is easy to notice.

The available 1991 Daihatsu products shown for 155/80R13 do not carry tube-type markings such as TT, and one version is marked with a P-metric size in a modern radial format. That points toward contemporary tubeless-style radial construction for this size. Even so, the wheel itself still determines whether tube use is appropriate in practice.

A 1991 Daihatsu Charade with original 13-inch passenger-car wheels will often be used with tubeless radial tires, but wheel condition matters just as much as the tire. Check for rust, pitting, bent beads, or damage around the valve-stem hole before mounting new tires. If the car has unusual wheels or a prior modification history, confirm compatibility with the specific tire and wheel combination before installation.

All three 1991 Daihatsu Charade tire sizes here—145/80R13, 155/80R13, and 165/70R13—mount on 13-inch wheels, so they share rim diameter compatibility. That means the original wheel diameter does not automatically force a choice between them. The more important variables are wheel width, section width, and the profile each tire brings to the car.

A buyer should not assume that every original 1991 Daihatsu wheel is equally suitable for every one of those sizes without checking the wheel width against the tire manufacturer’s approved range. The safest approach is to verify the actual wheel dimensions first, then match the tire size that belongs on that Charade application. Diameter compatibility is only one part of the fitment picture on a small car like the Charade.

A 1991 Daihatsu stored on its tires should be kept in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber. Keeping the tires properly inflated and moving the car occasionally helps reduce flat-spotting during long periods of inactivity. Clean, dry floors and a stable indoor climate also help preserve sidewalls and tread.

For a light car like a 1991 Daihatsu Charade, long static storage can still leave tires feeling temporarily out-of-round on the first drive if pressures are neglected. If the car will sit for months, many collectors either roll it periodically or support it in a way that reduces constant loading on one contact patch. A brief visual check before returning the car to service is always worthwhile after seasonal storage.

On a 1991 Daihatsu, tire age usually matters more than mileage because cars like the Charade are often driven less than a modern commuter. A common collector-car guideline is to inspect tires carefully once they are around five to seven years old and to treat the ten-year point as a strong replacement consideration regardless of tread depth. The DOT date code on the tire sidewall is the starting point for that timeline.

A tire on a 1991 Daihatsu can look usable and still be aged out by time, heat cycles, or poor storage conditions. Sidewall cracking, hardening, irregular wear, or vibration are stronger warning signs than tread depth alone on a lightly used older car. If the Charade is being prepared for regular road use rather than occasional local driving, age-based evaluation becomes even more important.

Tires on a 1991 Daihatsu should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, low pressure, and any sign that the tire is not holding air normally. On a small, light car, even modest pressure loss can noticeably change steering feel and ride behavior.

A more thorough inspection every few months is also smart, especially if the 1991 Daihatsu Charade spends much of its life parked. Check valve stems, bead areas, and the spare along with the four road tires. Catching age-related deterioration early is one of the easiest ways to avoid roadside trouble and to preserve the driving character that makes an older subcompact enjoyable in the first place.

1991 Daihatsu tires in the available 155/80R13 range include a T-rated option, which corresponds to a 118 mph speed ceiling. All three year-and-make sizes are radials, a construction type well suited to normal modern road use when the tire is in good condition and correctly matched to the wheel. In everyday use, the condition of the car, the age of the tires, and the Charade’s own mechanical state usually matter more than outright speed capability.

For a 1991 Daihatsu Charade, safe highway driving starts with realistic expectations for an older lightweight economy car. Tire pressure, wheel condition, alignment, suspension wear, and braking performance all deserve attention before a longer trip. Even with an adequate speed rating on paper, an aged tire or a neglected chassis can make the car feel less settled than it should at sustained road speeds.

Inflation pressure on a 1991 Daihatsu should begin with the vehicle’s factory recommendation for the exact Charade application and tire size. Within the available 155/80R13 products, several tires carry a maximum load of 959 pounds at 35 psi, but that figure is the tire’s rated maximum load pressure reference, not automatically the pressure you should run on the car. Pressure should always match the vehicle requirement first, then stay within the tire’s own limits.

That distinction is important because a 1991 Daihatsu Charade is a light car, and overinflating to the tire’s maximum sidewall figure can change ride quality and contact patch behavior. Use the factory placard or owner’s manual as your baseline, then confirm the tire’s own sidewall information before setting pressures. Recheck pressure regularly, especially if the car sits for long periods between drives.

Before a longer drive in a 1991 Daihatsu, inspect each tire for cracking, tread separation, cuts, bulges, and uneven wear, then verify cold inflation pressure. Check the valve stems, the spare, and the wheel condition as part of the same walk-around. Since the Charade uses multiple 13-inch tire sizes depending on application, it is also wise to confirm that the spare actually matches the car’s wheel diameter and basic fitment needs.

A longer trip in a 1991 Daihatsu Charade should also include a broader mechanical check beyond the tires alone. Brakes, cooling system, belts, hoses, lights, and fluid levels all deserve attention on a car of this age. Good tires are only one part of roadworthiness, but they are the part you can inspect most quickly before leaving and the part most likely to show age-related warning signs early.
