My car has two diffent kinds of tyres on them. Two the same make on the front and two the same make on the rear. Both my front ones are shot, I need to replace them both. Now do I get the same kind the rears are, or buy something else? My fronts are 17" and they are called Nexen N3000. My rears are Federal Super Steel, size of my tyres are 215-50-ZR17. Also whats the best place to buy tyres from 🙂. Cheers
