Tyres are just like anything else , and you can get dirt cheap ones ( which may be fine if you are only going 400 metres at 10 mph ) . Beware though , tyres deteriorate with age , and whether they are stored , exposed to sunlight ( UV ) , or if they kept under load , and not rotated every 4 weeks or so . The Caravan Club's advice is do NOT use any tyre over 7 years old , and avoid anything over 5 years old . ( or anything at all with bulges , flats or serious cracks ) . You can tell how old a tyre is from the code on the sidewall.
