Triumph Repair: wheels, austin minis, car wheel

Question
Hoping you can offer a suggestion, done search based on 3.75 pcd, I have a car wheel on my trailer which is 10" dia with 4 stud pcd of 3.75, see from this site that Triumphs used this pcd, where there any 10" ones, am desperate to identify the vehicle it came from, Barry

Answer
Hi Barry,
The smallest wheel on Triumphs imported into the US were 13". If the wheel on your trailer is 10" and is a car wheel it may be one of the Morris or Austin Minis. If it were one of them it would have a great amount of offset as they were front wheel drive. I don't remember the bolt pattern size.
