Well like everybody else, I had to have Michelin Redlines. The car don't look right without them. So, I ordered 4 new ones for my TR6 in 2006. I asked before the order, have these tires been sitting in a warehouse for a long time, the answer was NO. So, after a shipping fiasco, I finally had all 4. Guess what, at least one was, if I remember right, 8 yrs. old, and the rest I think between 5-7 years old. I raised cane, and they said send them back if I didn't like them, even called Michelin. But, what else would I use? So I kept them. Now, next to OD, I think the best improvement is modern tires. I also think the best way to make the car look right is to use Panasport wheels and modern tires. I wish I had sent them back, they are expensive. I still only use Michelin on my regular ride, they are the best tires. But, the Redlines are old technology, the car don't drive as good as my buddies TR6's with modern rubber,not even close. I'll probably sell the Redlines, they are from the last batch Michelin made, so I doubt there are any much newer that these around. Have about 4k miles on them. If you buy new tires, check the date code.
