Hi, To get members inspired to help please throw up a little bit of info on your Dai and a pic or two. Someone will know exactly what rims are around. What will you use it for? My view on rim is to see what tire sizes are available in the diameter and width you’d like. There are not many choices in 14". 175/45/15 will be close to the orig diameter of around 540mm. Offset will be about plus 35. A six inch rim would be the min I’d use, though you’ll prob have trouble finding such. PCD is 100. Sirion 15" will fit but are narrow, the one set I had was 5" wide.
Not really up to what sizes are available. A quick look and I see (as you know) there are no 14"s, and in 15" you are looking at 165/50R15. I was gong to run 195/50r15 on a 7" rim (about plus 34mm I think). The latter get big and don’t fit without a lot of work. More work than just flares.
