I'm currently flying on the original McCreary tires that came with my IV-P kit, but realize they're not the best.  My problem is that I have very close clearance in my wheel wells.  To anyone who is flying with Michelin or Goodyear tires - are they the same size and profile as the McCrearys or are they larger or fatter?  Thanks for any info (please specify make AND model of tires.)
