compatible tyres to re050a

[pitbull turbo]

hey. i have a mazda6 mps 4wd and i have one tyre that needs replacing, it currently has bridgestone re050a tyres on, im not keen on these tyres so when i have some more money il swap all for tyres but for now i need one tyre which will work with the re050a at a lower price than the re050a's the size is 215/45/18 and needs to be ok for heavy cars.
