Districts per state. State with the most: California (53) (Same as in 2000) States with the fewest (only one district at-large): Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming. Alaska, Delaware, and Wyoming are the only states that have never had more than one district.
However, since theyâre smaller and more compact, theyâre missing out on two key aspects of a regular tire: durability and stability. Most of these spare tires have a limited top speed of 55 mph. You can expect to get about 50 miles on a spare tire like this, and some are rated up to 70 miles. That should be enough for you to find a mechanic who can patch up your flat, or a tire shop where you can replace the punctured tire.
The conventional wisdom is that your road bike tires last anywhere from 1,000 to 3,000 miles. High-end tires should last at least 2,500 miles. Racing tires, which are designed for speed and high-performance, may need replacing after 1,000 miles, but tough touring tires can last as long as 4,000 miles. If you are a commuter who rides on asphalt you may have slick or inverted tread, which improves the road-life of your tire.
