I currently have 305 mt et streets on my turbo cobra and the hook good. Im looking to possibly go to a little bigger street tire to keep cost down and similar traction. 315s seem to be hard to find for 19in rim but there seem to be a bit more options in 305 and 325. Will 325s fit without modification and if so which tires are recommended for my 800hp? I have low profile bolts on my irs.
