Hi. I currently have 245 / 45ZR20. A couple of the wheels are reported to be buckled and tyres are nearer ending their days so I am looking to get new wheels / tyres. I will be driving 10k a year - mostly motorways to / from Scotland. I am more interested in comfort and economical driving. I have a converted T6 camper. I would prefer Matt black or silver wheels. Thoughts / advice please.
