Hi MaxWedge. We had a discussion about this back in August. If you search this forum with the title words "Minilite Wheels" and my username "Vette" you will find at least two post about my search for the wheels you are looking for. I contacted all of the usual suspects about Minilite wheels for my 5 lug BJ7. They all said they do not supply any "Minilite" type of wheel for the 5 lug Healey. Which is 5 on 5 by the way. Only Moss list a number for a "Minilite Like" wheel for the Big Healey. And it is 5.5" wide. So wanting new wheels for my car, I bought them from Moss. And they have stamped right in the casting, " MADE IN THE UK ". And they're pretty nice. And my BJ7 is alot smoother with them and the new tires. So just to let you know, I'm happy with them. I'll try to attach a pic. Dave.
PS: by the way, I have new Nexen 165/80-15 tires on them. You can go up to 185s but i decided to stay with the 165s because that is want has been on my car for years. You note if you read some spec from different tire manufacturers that the will state that 165 tires can go on a rim width from 4.5 to 6.0. Then some manufacturers won't state that. I searched for weeks to verify that the 165s will work on the 5.5 rim width. As an example, Coker Tire states the rim width for 165s is 4.5 to 6.0. Anyway, Good Luck.
