- The standard 1500 & 1600 MGA left the factory with 5.60-15 crossply tyres. There isn’t currently a 5.60-15 crossply tyre we would recommend.
- 155HR15 is the radial alternative tyre size for an early MGA.
- We would suggest 155HR15 Pirelli Cinturato as the best sports car tyre for an early MGA.
- Michelins 155HR15 XAS is another excellent performance option and the 155TR15 Michelin X is an absolute bargain.
- Suggested tyre pressures for single cam shaft MGA cars with 155R15 radial tyres would be 28psi front and 32psi in the rear.
- We recommend fitting the 15 E 13 Michelin inner tubes. Always run inner tubes with wire wheels.

MGA Twin Cam Tyres
It is worth pointing out that the twin cam MGA fitted a slightly larger crossply tyre, and as a result many of the earlier cars like to fit the larger radial fitments as well. But we would suggest that the handling of these single cam cars benefit from the lighter 155R15 tyres.
- The Twin Cam version of the MGA came out fitted with 5.90H15 Dunlop RS5 tyres. However, sadly, Dunlop no longer make any historic road tyres.
- We would suggest the best road tyre for a Twincam MGA road car would be 165HR15 Pirelli Cinturato CA67. The perfect period radial tyre with a carcass designed to improve cars like the MGA.
- Another very good performance option would be the Michelin 165HR15 XAS, and the 165SR15 Michelin XZX is an absolute bargain.
- The engine of the Twin Cam MG A makes the front a little heavier so we would suggest 30psi front and 332psi rear for suitable tyre pressures.
- Fitting the 15E Michelin inner tubes is ideal for MGA. Always run wire wheels with inner tubes.
Low profile MGA Tyres
The MGA came out on crossply tyres. So even when you fit a 155R15 tyre it will give you more grip than it had originally in standard form or the Twin cam with its 5.90H15 Crossply tyres. So if you fit a 165R15 radial tyre, your steering is already heavier, slower and vaguer than was intended to be. This is diminished by fitting genuine period tyre such as the Cinturato CA67, XAS, X or XZX which is why we recommend them.
If you truly must go larger in size than 175/70R15 or 185/70R15 really is the widest you should consider going. We would suggest the Pirelli CN36 or Avon CR6ZZ as they are tyres that are designed to be fitted under these conditions, and they will diminish the derogatory effect of over-tyreing a classic car.
Many people will recommend tyre sizes like 195/65R15 and 205/60R15. It is worth pointing out that you should not fit inner tubes with these tyres and you should always fit inner tubes in wire wheels. Fitting fat tyres like that does spoil the handling of small light rear wheel drive sports cars.

Other Options for MGA
The MGA was originally fitted with a 560x15 crossply tyre. The MGA however will benefit from a radial tyre that is more suited to the roads and traffic conditions of the modern era, offering better grip, stopping power and stability. A 155HR15 PIRELLI CINTURATO ™ is the closest radial alternative to a 560X15; the CINTURATO ™ would be an excellent option for your early MGA. it will keep the steering nice and light. The later MGA 1600 and twin cam models originally fitted a larger 590H15 Dunlop RS5. We would suggest the best radial alternatives would be 165HR15 Michelin XAS or 165HR15 PIRELLI CINTURATO CA67 ™. The CINTURATO ™ is a genuine period tire. As well as looking perfect, they will also keep the handling beautifully progressive and predictable. MG also fitted CINTURATO ™ to their later cars. Although the Michelin XAS was introduced later than the MGA it would have been fitted as an upgrade to many cars in the late 60's. The design of the XAS compliments the handling of sports cars like the MGA of the late 50's and 60's. It was a tyre developed to improve the directional stability of cars that were now finding themselves cruising on motorways at speeds of over 60 mph for extended times.
Many people want to fit larger tyres to their MG A. Fitting wider tyres makes the steering heavier and less progressive. However if you are prepared to put up with the deteriorated handling the best way to diminish the derogatory effects of "over tyreing" your MGA is fitting a period tyre with rounded shoulders such as the 185/70WR15 PIRELLI CINTURATO ™ CN36 or 185/70VR15 Michelin XWX. fitting anything of a lower profile will mean you cannot fit inner tubes and youi will have a tyre of a very different shape which is not suited to cars of this period.
