can I replace my front EMT (no flats) with regular F1 Eagles tires while keeping the rear EMT tires which don't need to be changed? Of course I will replace them with the regular F1 when the time comes.

I did that to by 2001, Didn't have any issues, I finally went with all regular because they run quieter and are lighter. I replaced the rears last month and the fronts this month. I heard that the only difference besides the 50 miles you have to drive to a shop for tire repair is that the regular tires compared to the EMT are lighter and quieter. I'm not an expert, just know that it worked for me. Here's a good web site for tires- http://www.discounttiredirect.com/di...011447&yr=2001 (http://www.discounttiredirect.com/di...011447&yr=2001)
Hope that helps some, Good Luck
