The 1963 MG MG belongs to an era when small British saloons balanced tidy dimensions, light road manners, and a distinctly European touring character. For owners keeping one on the road today, tire choice plays a major role in both appearance and driving feel. This application centers on two 14-inch fitments: a 5.90-14 bias-ply for a traditional vintage presentation and a 165R14 radial for a more modern road-going setup. Within the radial size, choices include classic blackwall tires from Pirelli, Michelin, and Vredestein in well-known period-style series. The real decision is whether to preserve the original-style construction theme or move toward radial behavior while confirming wheel compatibility first.
Which Tire Size Is Right for The 1963 MG MG
The 1963 MG MG uses two primary tire sizes on a 14-inch rim: 5.90-14 in bias-ply construction and 165R14 in radial construction. Since both sizes apply to the same covered sub-model, the key choice is less about trim differences and more about whether the car is being kept in a traditional bias-ply format or fitted with a radial alternative. Verifying the actual wheel setup is still important, especially on a vintage car that may have been updated over time.
165R14 is a Euro-metric radial size in which 165 represents the nominal section width in millimeters, R identifies radial construction, and 14 indicates a 14-inch wheel. On a 1963 MG MG, this size suits owners looking for a radial option while staying within a period-appropriate sizing convention. Available blackwall choices include the Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic, each with its own series character and rim-width specification. It is a useful size to evaluate when road use and traditional European tire appearance both matter.
5.90-14 is a numeric bias-ply size, with 5.90 indicating the nominal section width in inches and 14 identifying the wheel diameter. For a 1963 MG MG, this format reflects the earlier sizing and construction style associated with many vintage applications. Bias-ply tires are typically chosen by owners who want a more traditional look and period-style fitment approach rather than a modern radial presentation. This size deserves consideration when restoration appearance is the priority and the car is being kept close to its original-era tire character.
Fitment is straightforward for the covered 1963 MG MG sub-model, since the same two 14-inch tire choices appear across it. The important decision is not trim-specific sizing, but whether the car will remain on a vintage-style bias-ply tire or move to a radial setup.

Tire questions for a 1963 MG MG usually come down to size, 14-inch rim fitment, bias-ply versus radial construction, and choosing a tire that suits both the car’s period character and intended road use.
Tire Size & Fitment
What tire size fits a 1963 MG MG?
A 1963 MG MG uses two primary tire sizes: 5.90-14 in bias-ply construction and 165R14 in radial construction. Both are 14-inch fitments, so the main difference is the sizing system and tire construction rather than wheel diameter.
That means the real choice is deciding whether the car will stay with a traditional bias-ply setup or move to a radial tire in a comparable vintage format. On an older MG, it is smart to confirm the actual wheels on the car before ordering, since replacement wheels or earlier modifications can affect width, clearance, and overall suitability.
What size rim does a 1963 MG MG use?
The 1963 MG MG uses a 14-inch rim with both of its primary tire sizes. The radial 165R14 and the bias-ply 5.90-14 share that same rim diameter, which simplifies the basic wheel-diameter question.
Rim diameter is only the first check on a collector car. Wheel width still matters, especially when comparing among radial products, because some 165R14 options carry specific approved rim-width ranges. A car that has had its wheels changed over the years may still have a 14-inch diameter but not the same width or offset as the original-style setup.
What does 5.90-14 mean on a 1963 MG MG?
5.90-14 is a vintage numeric bias-ply size. The 5.90 figure refers to the nominal section width in inches, and the 14 identifies the wheel diameter in inches. On the 1963 MG MG, it represents a traditional bias-ply fitment rather than a modern metric radial format.
Understanding that format helps separate an original-style tire choice from a radial alternative such as 165R14. A buyer considering 5.90-14 is usually focused on vintage appearance and period-style construction, while a buyer comparing it to a radial should also review the car’s current wheel condition, alignment, and any suspension changes before making the switch.
Bias-Ply & Radial Options
Should I use bias-ply or radial tires on a 1963 MG MG?
A 1963 MG MG can be set up with either a 5.90-14 bias-ply tire or a 165R14 radial tire. The bias-ply size keeps the car in a traditional vintage construction, while the radial size follows a more modern road-use approach within a period-friendly European tire format.
The right direction depends on how the car is used and presented. Owners focused on restoration-oriented appearance often stay with bias-ply construction, while regular road drivers may prefer to evaluate radial options. Before changing construction, check wheel width, suspension condition, alignment, and body clearance so the new tire choice matches the car’s actual setup.
Is 5.90-14 a bias-ply or radial tire for the 1963 MG MG?
On the 1963 MG MG, 5.90-14 is a bias-ply tire size. It uses the older numeric sizing system common to vintage applications, and it is distinct from the 165R14 radial fitment also used on this car.
That distinction matters because construction affects both the car’s appearance and the kind of replacement tire you are shopping for. Someone keeping the MG close to its original-era look may want to stay with the 5.90-14 format, while someone moving toward a radial setup should confirm that the wheels and clearances are appropriate for the alternative size.
Can I switch my 1963 MG MG from 5.90-14 bias-ply tires to 165R14 radial tires?
The 1963 MG MG is associated with both 5.90-14 bias-ply tires and 165R14 radial tires, so a radial setup is part of the recognized fitment picture for this application. Even so, changing from one construction to the other should be treated as a deliberate setup decision rather than an automatic interchange.
A careful conversion starts by confirming the actual 14-inch wheels on the car, including width and general condition. Clearance at the fenders and steering range should also be checked, particularly if the MG has aftermarket wheels, refreshed suspension, or any ride-height changes. Matching all four tires and reviewing alignment afterward is also a sensible step.
Choosing the Right Tire
What should I consider when choosing a 165R14 tire for a 1963 MG MG?
Start with the basics: correct size, radial construction, and 14-inch wheel compatibility. For the 1963 MG MG, 165R14 choices include blackwall tires from Pirelli, Michelin, and Vredestein, with series such as Cinturato CA67, XAS, and Sprint Classic offering different period-style personalities within the same size.
After narrowing the size, compare details that affect fit and use, including approved rim-width ranges, weight, and how closely the tire’s appearance matches the car’s intended presentation. A lightly driven show car may call for a different choice than a regularly driven MG, so it helps to balance visual character, wheel compatibility, and expected road use together.
What brands offer tires for the 1963 MG MG?
For the 165R14 radial size used on the 1963 MG MG, available brands include Pirelli, Michelin, and Vredestein. Those options give the buyer a solid spread of well-known European-style vintage tire choices rather than a single-brand decision.
Brand should be one part of the selection process, not the only one. It is also worth comparing the specific tire series, blackwall presentation, weight, and approved rim-width range for the wheel on the car. Once size and wheel compatibility are confirmed, the brand choice becomes a matter of the tire’s character and how it fits the MG’s intended look and use.
What tire series are available for the 1963 MG MG?
In 165R14 radial fitment, the 1963 MG MG has access to several recognizable tire series, including the Pirelli Cinturato CA67, Michelin XAS, and Vredestein Sprint Classic. Each series stays within the same basic size while offering a slightly different take on vintage European tire design.
Series choice matters most after the fitment basics are settled. Once the wheel size and width are confirmed, the buyer can compare which series best suits the car’s visual theme and road use. A period-style touring presentation, for example, may lead to a different choice than a car being driven more often on modern roads.
Restoration & Appearance
Which tire should I choose for a period-style 1963 MG MG?
For a period-style 1963 MG MG, the 5.90-14 bias-ply size is the most traditional-looking starting point because it keeps the car in an earlier numeric bias-ply format. A 165R14 radial can also suit the car visually, especially when the goal is a vintage European look with more modern construction.
The right answer depends on whether the project is restoration-oriented or intended for regular road driving. Buyers pursuing exact historical authenticity should compare the tire choice against marque-club guidance or other vehicle-specific references. For many owners, the decision comes down to how strongly appearance needs to follow original-era practice versus how the car will actually be used.
How does tire construction affect the appearance of a restored 1963 MG MG?
Tire construction changes the visual impression of a restored 1963 MG MG even when the wheel diameter remains the same. A 5.90-14 bias-ply tire gives the car a more traditional vintage presentation, while a 165R14 radial introduces a more modern-looking sizing format and stance within a classic blackwall style.
That difference is often noticeable on a small British saloon, where tire proportions contribute strongly to the car’s overall character. Owners who want a restoration-oriented result usually weigh construction and size format as carefully as brand or series. The best choice is the one that supports the car’s visual goal without overlooking wheel compatibility and intended road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1963 MG MG?
Yes. Even though the 1963 MG MG uses 14-inch tire fitments, modifications can still change whether a particular tire setup is appropriate. Aftermarket wheels, altered wheel width, suspension work, ride-height changes, or body repairs can all affect how either 5.90-14 bias-ply tires or 165R14 radial tires sit on the car.
A vintage MG should be checked at full steering lock and through normal suspension travel before any replacement choice is finalized. Clearance to fenders, inner wheel housings, and suspension components matters just as much as the printed size. Cars that look stock can still carry wheel or suspension changes made decades ago, so verification is always worthwhile.
What should I inspect before driving a 1963 MG MG on new tires?
Before road use, inspect the wheels for damage, confirm lug hardware condition, and make sure the tires are mounted in the correct size and construction for the setup you chose. Tire pressure, valve stems, visible clearance, and even tread seating around the rim all deserve a careful look on a 1963 MG MG.
The rest of the car matters too, especially on a low-use collector vehicle. Steering components, shocks, bushings, wheel bearings, and alignment should be in sound condition so the new tires are not compensating for worn chassis parts. A short initial drive followed by a second inspection for rubbing, air loss, or uneven wear is a prudent practice.
How should tires on a collector 1963 MG MG be maintained?
Tires on a collector 1963 MG MG should be checked regularly for pressure loss, sidewall cracking, cuts, bulges, and uneven tread wear, even if the car is driven only occasionally. Vintage cars often spend long periods parked, which makes age, storage conditions, and visual inspection just as important as mileage.
Good storage habits help preserve both bias-ply and radial tires. Keeping the car away from prolonged sunlight, moisture, and ozone sources can reduce unnecessary aging, and moving the vehicle periodically can help avoid long-term flat spotting during storage. Before any longer outing, inspect the tires again and confirm the car still has proper running clearance.
