In 1976, MG still represented the classic British sports car formula in a market that was rapidly moving toward heavier, more insulated cars. The year’s lineup was simple but distinct: the MGB as the larger, more mature roadster and GT-derived platform, and the lighter, smaller Midget as MG’s nimble entry-level sports car. For 1976 MG vehicles, tire choice varies by model rather than being shared across the whole range, with the MGB using 165R14 and the Midget using 145R13. The important first step is confirming which model you have, because the correct tire is tied to both model identity and its original wheel diameter.
Which Tire Size Is Right for Your 1976 MG
Two tire sizes are used across 1976 MG vehicles, and they vary by model rather than being shared across the range. Because the MGB and Midget use different rim diameters, the real decision starts with confirming the correct model and wheel size before comparing brands or product details. Understanding that distinction first saves time and helps you choose a tire that matches the right MG platform.
Year(s): 1976|Fit(s): B|Construction: Radial|Rim: 14 in
165R14 is a euro-metric radial size with a 165-millimeter section width and a 14-inch rim diameter, with this format conventionally representing an 80-series profile. This size is specific to the 1976 MGB rather than universal across the year and make, and it is available from Pirelli, Michelin, and Vredestein in blackwall form; tube status varies by product, and H-rated versions carry a 130 mph ceiling. It suits an MGB owner who wants a period-appropriate radial size for a classic British sports car while still choosing among different brand characters within the same overall fitment. Rim width coverage in this size ranges from 4.0 to 6.0 inches depending on the tire.
Year(s): 1976|Fit(s): Midget|Construction: Radial|Rim: 13 in
145R13 is a euro-metric radial size with a 145-millimeter section width and a 13-inch rim diameter, again using the conventional 80-series profile associated with this format. This size is specific to the 1976 MG Midget, and it is available from Michelin and Firestone in blackwall form; tube status varies by product, and one product carries an H speed rating with a 130 mph ceiling. It is the right direction for a Midget owner who wants to preserve the smaller car’s light, responsive character with the correct radial format for its wheel size. Rim width coverage reaches 4.00 to 5.00 inches where specified.
Two MG models are covered for 1976. They do not share the same tire size, so identifying whether you have an MGB or a Midget matters before you move on to choosing a brand or product. Select your model below for model-specific fitment history and tire options.
1976 MG B
The 1976 MGB was MG’s established sports car, known for its longer wheelbase, sturdier feel, and broad appeal among British roadster enthusiasts. Its tires mount on 14-inch wheels, giving it a distinct fitment path from the smaller Midget and aligning with the MGB’s more substantial chassis and touring character.
The 1976 MG Midget carried MG’s smallest and most playful sports car tradition, with compact proportions and a lighter, more tossable personality than the MGB. Its tires mount on 13-inch wheels, so the correct fitment is unique to the Midget and should not be confused with the MGB’s larger wheel size.
Five products are available across two tire sizes for 1976 MG vehicles. The 165R14 has three radial blackwall choices from Pirelli, Michelin, and Vredestein, while the 145R13 has two radial blackwall choices from Michelin and Firestone. Confirm your model first, since tube markings and speed ratings can vary between products within a size.
These FAQs cover how 1976 MG tire sizing splits between the MGB and Midget, what 145R13 and 165R14 mean, how blackwall radial choices differ by brand, and what to check for storage, setup, and longer road use on a collector British sports car.
Size Basics & Fitment
What tire sizes fit 1976 MG vehicles?
1976 MG vehicles use two different tire sizes depending on model. The 1976 MG MGB uses 165R14 radial tires on 14-inch wheels, while the 1976 MG Midget uses 145R13 radial tires on 13-inch wheels. These sizes are not interchangeable across the two models because the rim diameters are different.
That means year and make alone are not enough to choose a tire for a 1976 MG. The first check should be whether the car is an MGB or a Midget, then whether the wheels on the car still match the original diameter. Once that is confirmed, you can compare the available blackwall radial options in the correct size instead of trying to adapt a tire from the other MG model.
What does 165R14 mean on a 1976 MG tire?
On a 1976 MG, 165R14 is a euro-metric radial size used on the MGB. The 165 refers to nominal section width in millimeters, the R identifies radial construction, and the 14 is the wheel diameter in inches. In this style of sizing, the profile is conventionally treated as an 80-series metric radial unless a different aspect ratio is stated.
For an MGB owner, that code helps separate wheel fitment from brand choice. A 165R14 tire belongs on a 14-inch wheel, and available examples in this size include H-rated versions with a 130 mph ceiling as well as differences in approved rim-width range. Verifying the actual wheel width before ordering is worthwhile, especially if the car has replacement wheels or a long restoration history.
What does 145R13 mean on a 1976 MG tire?
On a 1976 MG, 145R13 is a euro-metric radial size used on the Midget. The 145 identifies a nominal section width of 145 millimeters, the R means radial construction, and the 13 means the tire mounts on a 13-inch wheel. As with other early metric radial sizes of this kind, the profile is conventionally understood as an 80-series format.
That sizing tells a Midget owner that the tire is meant for the smaller MG platform, not the larger MGB. It also helps explain why the available choices keep a narrow, classic footprint that suits the Midget’s lightweight sports-car layout. Before choosing between brands, confirm that the car still wears 13-inch wheels and that the wheel width falls within the tire’s approved range where that range is stated.
Buying the Right Tire
What sidewall styles are available for 1976 MG tires?
1976 MG tires in both 165R14 for the MGB and 145R13 for the Midget are available in blackwall form. That keeps the appearance close to what most buyers expect on a mid-1970s British sports car, where a clean black sidewall looks more natural than the whitewall treatments associated with many American cars of earlier decades.
For a restoration-minded owner, blackwall is the straightforward choice because it fits the MG’s market position and visual character. It also simplifies brand comparison, since the main differences shift from sidewall styling to details such as speed marking, rim-width coverage, and the overall personality of each tire line. If your goal is authenticity with a tidy late-classic appearance, blackwall keeps the car looking right.
What brands make tires for 1976 MG vehicles?
1976 MG tires come from several established brands, with the exact brand depending on size. The 165R14 MGB fitment is available from Pirelli, Michelin, and Vredestein, while the 145R13 Midget fitment is available from Michelin and Firestone. All of these options are radial blackwall tires suited to classic European-style fitments.
Brand choice on a 1976 MG usually comes down to the model you own first and your preferences second. MGB owners have a broader spread of brands in 165R14, which can matter if you are matching a particular period feel or a familiar name. Midget owners have a narrower field, so wheel-size confirmation becomes even more important before comparing the two available 145R13 directions.
What is the difference between Michelin XAS and Vredestein Sprint Classic for the 1976 MG MGB?
For the 1976 MG MGB, both the Michelin XAS and Vredestein Sprint Classic are 165-series radial blackwall tires for 14-inch wheels, but they differ in some useful details. The Michelin XAS in 165HR14 carries an H speed rating and fits rim widths from 4.50 to 6.00 inches, while the Vredestein Sprint Classic in 165HR14 also carries an H rating but fits 4.0 to 5.5-inch rims and has a published load figure of 1,102 pounds at 51 psi.
Those differences matter most when you are matching the tire to the wheel already on the car. An MGB with narrower wheels may lean more naturally toward the Vredestein’s stated range, while a wider factory-style or replacement wheel may align more comfortably with the Michelin’s range. Checking the actual wheel width before making a final choice is the best way to avoid a mismatch.
Fitting & Setup
What rim width do 1976 MG tires require?
Rim-width guidance for 1976 MG tires varies by size and product. In 165R14 for the MGB, Michelin XAS fits 4.50 to 6.00-inch rims and Vredestein Sprint Classic fits 4.0 to 5.5-inch rims. In 145R13 for the Midget, Firestone F560 fits 4.00 to 5.00-inch rims.
That range is important because wheel width affects the tire’s shape, steering feel, and how naturally the sidewall sits on the rim. If your MG still has original wheels, comparison is usually straightforward, but restored cars often pick up replacement wheels over the years. Measuring the wheel before ordering is the safest approach, especially when choosing between two brands with different approved rim-width windows in the same nominal size.
Do 1976 MG tires require inner tubes?
Inner-tube status for 1976 MG tires varies by product. The Michelin 165HR14 for the MGB and Michelin 145HR13 for the Midget are marked TL, indicating tubeless construction, while other tires in those same sizes are not uniformly marked the same way. That means tube use should be confirmed product by product rather than assumed from size alone.
The wheel itself matters just as much as the tire marking. A tubeless tire mounted on a wheel that is not suitable for tubeless service may still call for a different setup, especially on a vintage car with older or restored rims. Check the sidewall marking on the exact tire you choose and confirm the wheel condition and design before final installation.
Maintenance, Storage & Longevity
How should I store a 1976 MG when the tires are fitted?
A 1976 MG should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, and other ozone sources that can age rubber. Keep the tires clean, maintain inflation, and move the car periodically if possible so one section of the tread is not carrying the same load for months at a time. Radial tires generally resist prolonged static deformation better than old-style bias-ply tires, but they still benefit from thoughtful storage habits.
For a low-use MGB or Midget, storage practice often matters more than annual mileage. If the car will sit for a long season, many owners either roll it occasionally or take weight off the tires with properly positioned stands while leaving the suspension supported appropriately. Good storage protects sidewalls, helps preserve roundness, and reduces the chance of discovering cracking or pressure loss right before the first drive of spring.
How long do tires on a 1976 MG typically last?
Tires on a 1976 MG should be judged by age and condition more than by mileage. A collector-car tire deserves close evaluation once it reaches about five to seven years of service, and many owners begin serious replacement consideration at around ten years even if the tread still looks good. The DOT date code, sidewall condition, and how the tire has been stored all matter more than odometer use on a lightly driven classic.
That is especially true for cars like the MGB and Midget, which may spend long periods parked and then return to road use at highway speeds. A tire can appear attractive while still aging internally. If you have just purchased a 1976 MG and the tire age is unclear, checking the date code and inspecting for hardening, cracks, or irregular wear is a sensible first step before putting meaningful miles on the car.
How often should tires on a 1976 MG be inspected?
Tires on a 1976 MG should be inspected before every drive and again before any extended outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, embedded debris, and signs of air loss. On cars using a tube-type setup or older wheel components, the valve stem area deserves extra attention because slow leaks often start there.
Frequent inspection is especially worthwhile on a classic MG because the cars are light, direct, and quick to telegraph changes in tire condition through the steering. Catching a pressure issue early can save the casing and protect the wheel as well. It is also wise to inspect the spare, since a roadside backup that has aged out or lost pressure is not much help when you finally need it.
Restoration & Authenticity
What tires were originally fitted to the 1976 MG MGB?
A 1976 MG MGB would have been a radial-tire-era British sports car, and 165R14 is the size used here for that model. That places the car squarely in the period when metric-style radial sizing had become normal on many European vehicles. Original-equipment branding could vary by market and delivery context, so the most reliable restoration path is to confirm size, construction, and sidewall appearance first.
For most restorers, that means keeping the MGB on a blackwall 165R14 radial rather than treating it like an earlier bias-ply sports car. If you are chasing high-level originality, consult a marque club, period road tests, or factory literature tied to your car’s market. Those sources can help you sort out whether a particular tire name, tread style, or marking is appropriate for your specific restoration target.
Does correct tire fitment matter for showing a 1976 MG?
Correct tire fitment matters on a 1976 MG because judges and knowledgeable enthusiasts notice size, construction, and sidewall appearance very quickly. On these cars, the right blackwall radial look supports the period character, while an incorrect wheel diameter or an obviously modernized size can change the car’s stance and visual balance. For a serious show car, those details are part of the overall impression.
The standard is not always identical from one event to another, so it helps to decide whether your goal is marque-club authenticity, local-show presentation, or simply a tasteful period look. A 1976 MGB and a 1976 Midget should also be judged within their own fitment paths, since they do not share the same tire size. Event rules and MG clubs are the right places to confirm the finest points of originality.
What tires were originally fitted to the 1976 MG Midget?
A 1976 MG Midget belongs to the same radial-era context as the MGB, and the size used here is 145R13. That narrow metric radial format suits the Midget’s lighter, smaller sports-car package and reflects the move away from earlier bias-ply practice by the mid-1970s. The most important authenticity markers are the correct size, radial construction, and blackwall presentation.
A restorer does not need to guess across the full MG range, because the Midget’s tire path is distinct from the MGB’s. Keeping the car on a proper 13-inch radial of the right narrow section preserves both visual proportion and period character. If your project is being prepared for detailed judging, compare your chosen tire against factory literature and seek model-specific guidance from MG specialists before finalizing the setup.
Safety & Road Use
Are 1976 MG tires safe for highway driving?
1976 MG tires can be suitable for highway driving when they are the correct size, in sound condition, and matched to a well-maintained car. H-rated versions in both 165R14 and 145R13 carry a 130 mph speed ceiling, which is well beyond normal U.S. highway use. On a 1976 MG, the practical limits on a long drive are often the overall condition of the brakes, suspension, steering, and cooling system rather than the tire’s speed symbol alone.
Safety depends on the complete package, not just the number on the sidewall. Tire age, inflation, wheel condition, and alignment matter every bit as much on an MGB or Midget as the model of tire itself. A fresh, correctly fitted radial on a sorted car is a very different proposition from an old tire on a vehicle that has been sitting, even if both share the same nominal size.
What inflation pressure should I use for 1976 MG tires?
Inflation pressure for a 1976 MG should follow the vehicle manufacturer’s recommendation first, with the tire maker’s maximum pressure used only as the tire’s upper rated limit rather than a blanket operating target. In the products here, the 165R14 Vredestein carries 1,102 pounds at 51 psi, and the 145R13 Firestone carries 825 pounds at 44 psi. Those figures belong to those specific tires and should not be transferred across brands or sizes.
The best practice is to start with the factory guidance for your MGB or Midget and then confirm that the chosen tire is being used within its own rated limits. A classic sports car can feel very different with only a small pressure change, especially one as light and communicative as an MG. Recheck pressures when the tires are cold, and revisit them whenever the car’s load or usage pattern changes.
What should I check before taking a 1976 MG on a longer drive?
Before a longer drive in a 1976 MG, inspect each tire for cracks, bulges, cuts, irregular wear, and proper cold inflation. Confirm that the wheels are sound, the valve stems are in good condition, and the spare is usable and inflated. If your chosen tire or wheel setup involves a tube-type arrangement, include the valve hardware and any signs of slow leakage in the pre-trip inspection.
A longer outing in a classic MG calls for a broader mechanical check as well, since tires are only one part of the car’s readiness. Steering response, brake feel, wheel-bearing noise, and suspension condition all affect how confidently the car will track at speed. Taking ten extra minutes in the garage can prevent the kind of roadside problem that spoils a drive and risks damage to hard-to-replace vintage components.
