Hey Guys really enjoying this thread and all the good information.. I picked up my 2010 Silver Eagle M1101 on Monday,, Its brand new It's crazy they are selling these.. Anyway off I went to Craigslist for some Chevy rims with the lug cap covers. I have read all the threads I can find on these trailers and had found where it was posted to use 9/16" x 18 Dual thread lug nuts for the rims I bought to work with the lug cover.. The 2010 M1101 does not have that size stud.. I went to a used tire store he gave me 1- 9/16" x 18 to try and it is to small for the stud.. I then went to several auto parts stores and lowes and depot with the original nut and no success.. From what I saw at the different stores I'm thinking it is a metric 14 x 1.25 anybody have any info on this ?? I looked in the manual it called for part#90640 but no description on what size nut that part is..
