Yes... Never rotate your tires. The back tire wears down faster then the front. So when I put a new tire on the bike. I pull the front one and put it on the back. Then install the new one on the front. this way you get more miles from the back tire and save some money.

The tires that I run are rated for 2200 miles. I need a new back tire on the back after 1000 miles. So I put the front tire that has 1200 miles on it and put it on the back. Now I get an other 500 miles out of it on the back. If I just put it on then back and run it till it needs to be replaced, I'd only get 1000 miles out of it. But by doing the above I get 1700 miles from the tire. And you'll always have a good tire on the front.

So there you have it.

This morning I put in a commute of 33.78 miles to and from work. All and all it was a nice ride. I did have to go 15 miles out of my way to get the miles, but it was for the commute. I end up with a average ride speed (both ways) of 20.06 mph
