I have a question for the brains trust that is HK. My little used MINI had her MOT today, and passed with one advisory - a nail in one of the tyres . The tyres are run-flats, so can't be repaired. They were changed two years ago and have done fewer than 500 miles since. Trouble is, Dunlop no longer supply the exact same tyre. I only need to replace one, and I've had different answers from the garages I've asked...so my question is; - is is better to buy the same tyre (Sport SP01) with a different speed rating (84W instead of 84V), or; - buy a different Dunlop tyre with the exact same rating. I know both answers are legal, and I'm told having a higher speed rating is fine but any advice on what to do for the best appreciated!
