Longstone classic tyres recommend the 475/500x20 Firestone, for steady road use, the Vintage Alvis 12/50 as they keep the steering light and aesthetically look very vintage. However if you are what we call a "Spirited driver" you may benefit from the stronger structure of the Dunlop vintage tyre.
Vintage Alvis 12/50
The Alvis 12/50 is a car introduced by the British Alvis cars company in 1923. It went through a series of versions with the last ones being made in 1932. A range of factory bodies could be specified in two and four-seat form with either open or closed bodies.
The first models were designated SA and SB and had a 1496 cc 4-cylinder overhead valve engine in SB. The SA usually carried two-seat bodywork often the classic so called "ducks back" style named after its pointed rear end said to resemble that of a duck. All the 12/50s had a four speed non-synchromesh gearbox.
Alvis Speed 20
Longstone classic tyres recommend the 475/500x20 Firestone for the early Vintage Alvis speed 20 as they keep the steering light and aesthetically look very vintage. The original equipment for these cars was 525X20. However they tend to make 550X20 tyres these days which make the steering heavier.
Vintage Alvis Speed 20
The engine for the Speed 20 was based on the one used in the preceding Silver Eagle cars but heavily modifed to give 87 bhp. The chassis was new and lowered by making it a "double drop" type where the side rails go over the front and rear axles. A centralised lubrication system was fitted allowing oil to be provided to moving suspension parts through a maze of pipework. Both front and rear suspension used half-elliptic leaf springs and the brakes with 14 inch drums, mechanically operated. The four-speed manual gearbox was mounted in-unit with the engine.
The car could be fitted with a variety of coachwork. Standard bodies were a four-door saloon from coachbuilders Charlesworth or four-door tourer by Cross and Ellis, but some cars were supplied in chassis form and carried bodies by coachbuilders such as Vanden Plas.
Longstone classic Tyres recommend the classic 185x16 Michelin X as they are a genuine period Radial tyre first introduced in 1949. The fitment of a radial tyre will improve the directional stability and be more sure-footed on the road. This will diminish the wandering effect which is what we need on today's more modern faster roads cruising at higher speeds than in period. However fitting the 185x16 Michelin X A Genuine period radial of the correct diameter will do all the above and also keep the steering lighter than other radial tyres in this size, making it an easy choice when buying new boots for your classic Alvis.
If you are what Longstone classic tyres would call a spirited driver doing higher speeds for longer and in a more sporting manner, then the 600WR16 Michelin Pilote X @ £289.00 is the tyre for you it offers you outstanding grip and comfort in all conditions.

Alvis TA14 history
The Alvis TA 14 was the first car to be produced by Alvis cars after World War II. It was made from 1946 until 1950 when it was replaced by the classic Alvis TA21.
The car was available as a four door Saloon by Mulliers of Birmingham but there were also Tickford and Carbodies drophead versions. The bodies were mounted on an updated pre war Alvis 12/70 chassis that was widened and lengthened but retained the non-independent leaf spring suspension and mechanically operated brakes. Disc wheels replaced the 12/70s wires.
The 1892 cc engine is a slightly larger bore version of the one used in the 12/70 and produced 65 bhp. It is fitted with a single SU type H4 1½ in. horizontal carburettor

Classic Alvis TE21
The body was a modified version of the TC108 G styled by Graber of Switzerland and built by Park Ward and distinguished by having twin headlights mounted one above the other. Saloon and drophead versions were available. The design was noted for its lack of bright side trim or creases moulded into the body parts. The windscreen was one-piece, curved, and not too highly sloped.
The 2993 cc engine, first used in the classic Alvis 1950 TA21, received a modified cylinder head and manifold which increased power to 130 bhp. A choice of automatic or five speed gearbox made by ZF was available. Suspension was independent at the front using coil springs, with leaf springs at the rear. Disc brakes were fitted to all wheels.
Recirculating-ball-type steering gear was fitted to reduce effort and power steering became optional in late 1964.
Although the car was replaced by the classic Alvis TF21 in 1966, the TE21 was still available to special order until 1967.
