I'm sorry if this has already been asked. I've been looking around for inner tubes for my 8.00-16 tires. I keep seeing 7.50 but not really finding 8.00 (in stores). I went to the tractor supply and found 6.00/7.50-16 tubes and picked one of those up to try it. I was just wondering if you all think that will work. I plan on filling them one day if that makes a difference.
