lets presume your talking about 17s, i have heard good things about Toyo...
hope you dont mind but i think it would be easier to tell you what to stay away from in terms of danger because of no grip....
In terms of cheaper tyres.
Sava Intensa: HARD compound do burnout after burnout, not the best at grip but last FOREVER.
Bridgestone B530s: worst tyre ever, simple
Khumo Ecsta(non supra): Hard Compound, pretty crap at grip.
Tornado Alphas: Pretty good at grip, medium compound. nice and cheap
Nankangs: Again Pretty good at grip with a medium compound. (i run these usually because i get them $135 each in 235/45/R17) Bang for buck i havent found better
Really i choice of paying out your ass, or substituting grip for wear....
Best tyre i have ever bought was Dunlop SP9000s and at $380 each they should have been aswell...
I dont know places to go in Morley.
