Currently I can not afford larger wheels. But I have to buy new tires. I am driving a 2008 mustang coupe with 16" wheels. The tires are 215/65R16. I can't find a good tire that size. I'd like to buy Potenzas or Continentals.... but a get varying sizes. Would for example 245/50R16 or 215/55R16 work out good? Please I need your help. What range in size would be acceptable and not look too small?
