rwhisen is absolutely correct. My tire guy strongly advises everyone as they leave his shop with new tires to be very careful for 10 or 20 miles until the slippery mold release compound wears off.
I had a shop tell me to take it for about 50 miles. I just put a new michelin commander 2 front tire on and it felt a little weird in turns for about 50-100 miles. After that it has been fine.
Outside temps will probably dictate amount of heat build-up I'm guessing. The temps are all over the place here during the fall & winter. So it could require constant adjustment to maximize tire life. Spring & summer are easy - it goes from warm to hot and just stays hot from about late May to mid-late September.
I appreciate the info, good stuff to know - will keep ya'll toasted.
I know that you have gotten a lot of advice here and I don't want to add any confusion to things but I will tell ya my story. I have had Dunlops and Avon Venoms on my Softail and my Indy mechanic is amazed at how many miles that I can get on a set of tires. I don't have any trouble getting at least 13,000 and the most that I have gotten was 15,000 on a set of tires which, being on a trip, I had worn them to the core before I was able to get to a shop to have them changed. There are a lot of factors that can cause tire pressure to change. I check my tires before I leave for a ride but I don't get **** about 1 or 2 pounds one way or the other because if I did, I would be constantly adjusting my tire pressure and I don't see the need. Based on the mileage that I get on my tires and the way that I ride, my way works good enough for me.
