The 1980 MG MGB belongs to the final stretch of one of Britain’s best-known open sports cars, a model valued for its simple mechanical character, tidy proportions, and easygoing road manners. By this point, the MGB had long established itself as a practical enthusiast car that still rewards correct tire selection. The 1980 MG MGB uses a 165R14 radial tire on a 14-inch wheel, keeping fitment straightforward. Within that size, the main choice is between blackwall radial options from Pirelli, Michelin, and Vredestein, each with its own period-style character. For restoration-minded owners and regular drivers alike, the real goal is matching the right look, rim compatibility, and road-use expectations.
Which Tire Size Is Right for The 1980 MG MGB
The 1980 MG MGB uses one primary tire size: 165R14, a radial tire for a 14-inch rim. The MK IV sub-model uses the same size, so the key decision is not choosing between multiple fitments but selecting the right 165R14 tire based on rim compatibility, brand, series, and the kind of period-style appearance or road use that suits the car.
A 165R14 size uses a 165-millimeter nominal section width, radial construction, and a 14-inch rim diameter. In this older Euro-metric format, the aspect ratio is not written into the size code and is commonly associated with an 80-series profile. For the 1980 MG MGB, this keeps the fitment in the radial construction the car uses, while giving a choice of blackwall tires from Pirelli, Michelin, and Vredestein across series such as Cinturato CA67, Michelin XAS, and Sprint Classic. This size is the right place to focus when preserving the MGB’s traditional proportions and confirming wheel-width compatibility before final selection.
Tire fitment is straightforward across the covered 1980 MG MGB sub-model range. The main value in checking the sub-model is simply confirming that the car remains on its expected 165R14 radial fitment before comparing available tire choices.

1980 MG MGB MK IV
The 1980 MG MGB MK IV uses the same 165R14 radial tire size as the core model fitment. That keeps tire selection centered on choosing the right blackwall radial by brand, series, and wheel-width suitability rather than sorting through multiple primary sizes.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1980 MG MGB?
The 1980 MG MGB uses a 165R14 radial tire. That is the primary fitment for this application, and the covered MK IV sub-model uses the same size, which makes the basic size question fairly simple compared with vehicles that vary by trim or package.
The next step is confirming that the car still has the correct 14-inch wheels and that no previous owner changed the wheel or suspension setup. Once that is verified, the decision shifts to selecting among available 165R14 radial tires based on brand, tire series, rim-width suitability, and the kind of traditional blackwall appearance you want on the car.
What size rim does a 1980 MG MGB use?
The 1980 MG MGB uses a 14-inch rim diameter with its 165R14 tire size. The tire size itself confirms that fitment centers on a 14-inch wheel, which is the critical dimension to verify before comparing replacement tires.
Wheel diameter is only part of the fitment picture, so it also helps to check actual wheel width before choosing a specific tire. Some available 165R14 products include stated rim-width ranges, and that can matter if the car has replacement wheels, restored original wheels, or a wheel setup that differs from what the car carried when new.
Does the 1980 MG MGB MK IV use the same tire size?
Yes. The 1980 MG MGB MK IV uses the same 165R14 radial tire size as the core 1980 MG MGB fitment. That means there is no separate primary tire size to sort out for this sub-model within the covered application.
Even with shared sizing, it is still worth checking the actual wheels on the car before ordering tires, especially on an older sports car that may have seen wheel changes over time. Once the 14-inch wheel setup is confirmed, the main comparison becomes tire series, brand character, and whether the selected tire’s rim-width guidance matches the wheel on the car.
Choosing the Right Tire
What should I consider when choosing a 165R14 tire for a 1980 MG MGB?
Start with the correct 165R14 size and radial construction, since that is the primary fitment for the 1980 MG MGB. After that, compare the available tires by brand, series, blackwall presentation, and any stated wheel-width or load details that help separate one option from another.
A useful choice often depends on how the car is used. A restoration-minded owner may focus on traditional appearance and period-style character, while a driver putting regular road miles on the car may pay closer attention to rim-width guidance and other product specifications. Matching the tire to the actual wheel and the car’s intended use usually matters more than choosing by brand name alone.
What brands offer tires for the 1980 MG MGB?
The 1980 MG MGB has 165R14 tire options from Pirelli, Michelin, and Vredestein. Those brands appear in blackwall radial offerings that suit the car’s traditional sports-car presentation while keeping to the primary 14-inch fitment.
Choosing among them comes down to the individual tire series and specifications rather than assuming one brand is automatically the right answer. It helps to compare the exact 165R14 product, any stated rim-width range, weight, load information where available, and the overall look you want on the car. That approach keeps the decision focused on fitment and use, not just the name on the sidewall.
What tire series are available for the 1980 MG MGB?
Available 165R14 tire series for the 1980 MG MGB include Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic. All three are radial blackwall options, but they represent different product lines within the same basic fitment.
Series choice matters because it helps shape the car’s final presentation and narrows the spec comparison. One owner may prefer the look or heritage of a particular series, while another may focus on stated wheel-width compatibility or load information. Keeping the decision inside the correct 165R14 size lets you compare those differences without drifting away from the MGB’s proper basic fitment.
Restoration & Appearance
Which tire should I choose for a period-style 1980 MG MGB?
A period-style 1980 MG MGB choice starts with the correct 165R14 radial size, since that preserves the car’s intended tire format and overall visual balance. Within that size, blackwall options such as Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic all keep the appearance aligned with a traditional sports-car presentation.
The right final pick depends on how closely the car is being restored and how it will be used. Owners aiming for a historically convincing look often compare tire series and sidewall presentation carefully, while drivers may also weigh wheel-width compatibility and road-use priorities. If exact originality matters, marque-specific historical references remain the best place to confirm finer appearance details.
Does correct tire fitment matter for a 1980 MG MGB restoration?
Yes, correct tire fitment matters because the 165R14 size plays a visible role in the 1980 MG MGB’s stance, wheel opening fill, and overall period presentation. Using the proper basic size helps the car look settled and appropriate rather than visually over-tired or under-tired.
Fitment also affects the restoration beyond appearance alone. A tire that suits the actual wheel width and retains reasonable clearance at the front and rear helps avoid problems that can distract from an otherwise well-sorted car. Even on a driver-quality restoration, staying close to the intended size and construction makes it easier to preserve the MGB’s character on the road.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 MG MGB?
Yes. A 1980 MG MGB may use the standard 165R14 fitment, but aftermarket wheels, wheel-width changes, altered ride height, suspension work, or body changes can all affect how that tire sits and clears. Older sports cars are especially prone to fitment changes after decades of repairs or upgrades.
Checking the actual wheel diameter and width is the first step, followed by a close look at steering and fender clearance. Tire selection should also account for the car’s present-condition setup rather than assuming every MGB remains stock. A careful measurement before purchase is far easier than discovering rubbing, poor wheel fit, or visual mismatch after the tires are mounted.
What should I inspect before driving a 1980 MG MGB on new tires?
Before road use, inspect wheel condition, verify correct air pressure, and make sure the tires are mounted on suitable 14-inch rims. It also helps to check for suspension looseness, worn steering components, and any signs that the car has uneven ride height or alignment issues that could affect how the new 165R14 tires behave.
A slow test drive is a smart follow-up after installation. Pay attention to steering feel, any rubbing at full lock, and whether the car tracks evenly. Classic cars that spend long periods parked should also have brake condition, wheel hardware, and overall chassis readiness checked at the same time, since fresh tires alone do not make an infrequently driven car road-ready.
How should 165R14 tires on a collector 1980 MG MGB be maintained?
165R14 tires on a collector 1980 MG MGB should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and uneven tread wear, and protected from long periods of inactivity without attention. Collector cars often age tires by time and storage conditions rather than by mileage alone.
Storage environment matters as much as road use, so keeping the car away from prolonged heat, direct sunlight, moisture, and ozone sources can help preserve tire condition. It is also wise to check for air loss before every drive and to inspect the tires more closely before longer trips. A lightly used classic may look fine at a glance while still needing careful tire evaluation.
