I need to get two new rear tires for my blaster. And I don't have a lot of money to do it with. I found a set of rear tires for 70na peace and they seem ok enough for me butttttt they are 25inch. I currently have 22s on it. Is 25s too big? It's a 05 blaster 200 stock.will I need spacers in the back to keep the tire from hitting my heal gards? Will my torque be enough to turn the tires efficiently? Here's a pic of the tires.
