I have a 89 sr5 ext cab 4x4 with regular suspension on it. Currently has 31 10.5 15s on it and was wondering what size tires I could go with next time if I decided to go bigger. Can you put 32 12.5 15s on it without them rubbing? Also what is the best fender flare covers for the buck?

 

If you cut off or hammer flat the pinch weld on the inner fender, then you can fit a 33 or 32. Search around a bit, there are many threads on this.
