Following the feedback from Gordon Hesketh-Jones that he has found Continental winter tyres difficult to find, Chris Hunt Cooke says "I think it may be possible to get
Continental tyres in a size for the MGBGTV8 through the French supplier I used last year - Pneus-Online."

The Pneus-Online website says "Continental Winter Contact TS800 is a winter tyre for passenger cars. Improved performance on snow and ice, the tyre offers excellent and improved vehicle handling. The tried-and-tested concept introduced by Continental offers more safety and comfortable driving experience. The advanced tread compound of Continental is moulded into tread pattern with honey comb sipes for improved dry and wet road traction. The V-shaped lateral grooves offer excellent protection against aquaplaning. The innovative tread design with biting edges provide good cornering stability and snow traction. The compact and independent tread block makes it possible for Winter Contact TS800 to offer superb and smooth driving and traveling experience. Safety and excellent grip are the special highlighting features of this Winter Contact TS800."

Remember you don't need snow for winter tyres to show a benefit for winter driving - they work considerably better in all conditions as temperatures drop below 7C. In some parts of the UK that can be as early as September or October. With average winter temperatures of 3.7C, winter tyres can offer 60% more grip than summer tyres and noticeably more traction and steering response.

Suitability of 175/70 R14 84T tyres for a Factory MGBGTV8?
The tyre size usually fitted today as the replacement for the tyre originally specified for the Factory MGBGTV8 - 175HR x 14 - is a 175/80 R14 88H. That tyre has an aspect ratio of 80% compared with the 70% of the Continental WinterContact TS800 tyre advertised above. But a check on the Pneus-Online website shows there are no winter tyres offered in the 175/80 R14 size. So what is the impact on gearing of using a 175/70 R14 tyre or another available tyre size?

Using a tyre size calculator the difference in static diameter is -5.5%:

However a further search shows there are brands offered in alternative sizes. Using another online calculator, and assuming the speedometer is set up for 175/80 R14 tyres, then:

175/70 R14 winter tyre produces a 3.5cm reduction in static diameter so if the speedometer shows 60 mph you would be doing 56.7 mph, a variance of 5.5%. The recommended maximum variance is 2.5%. The leading brand offered is the Vredestein Snowtrac 3.

185/70 R14 winter tyre produces a 2.1cm reduction in static diameter so if the speedometer shows 60 mph you would be doing 58.0 mph, a variance of 3.3%. The leading brand offered is the Vredestein Snowtrac 3.

185/80 R14 winter tyre produces a 1.6cm increase in the static diameter so if the speedometer shows 60 mph you would be doing 61.5 mph, a variance of 2.5%. The leading brand offered is a Goodride SW608.
