I don't think premium tyres are necessary on a caravan however mid range should be okay. On our Corolla which is only used around town, budget tyres are fine however the Jeep gets premium tyres.I am firmly of the ' buy the best' tyre in terms of cars. They can save your life. Hadfronts on a car I bought and the lack of grip made me change them asap. On a caravan however grip isn't an issue is it? With 60 the max and no one going to exceed corner grip of any EU approved tyre or aquaplaning since the car would go first due width, I won't be seeking a premium tyre when we change. Or am I wrong? I think budget should be fine.
