I bought a 4 year old bmw with run flat tyres which seemed like such a good idea 
Less than a year on I have since bought 5(!) new tyres for it. It can not cope with the rural roads. Tyre shop says that there is so much steel in the tyre walls that they have no give and burst when they hit potholes. I drove on the same roads prior to this in my previous tiny car with tiny tyres (hyundai i10 ) and did not pop a single tyre.
Can anyone recommend anything please? I do high mileage...20k a year so need good mpg, driving mostly on fast A roads with lots of pot holes so the car needs to be able to cope with that. Need a reasonable boot size and reasonable poke as sometimes you have to really put your foot down coming out of side roads round here, and to feel I am in a solid car if that makes sense. Don't care about look of the thing/makes etc. Budget up to 10k. Thanks
