I have an 89 Toyots Ext Cab SR5 with no lift but currently riding on 31x10.5x15s. I need to buy new tires and would love to get bigger ones. Does anyone know if I can fit any larger tires without rubbing. I know it's a Toy and not a real truck, but it saves on gas and I like the look. I will go offroading a little so don't think I just want to jack it up to be gay! Thanks.
