235/60/14 do fit 6" rims, but they are too big on the front. For me they have always grabbed the tab on the guard above the tyre and cut the tyre or damaged the guard. They are normally OK if you don't lower the front, but for some reason everyone wants to lower them to silly levels, and lowered or not 205/60/14 work well. HZ and WB handle and drive better at normal or just under normal ride height anway! If you want wider fronts 245/50/14 work better, but the problem is you have to use 7" rims and they look wider than 245/60/14 on 7" rims, so you end up having to run 275/60/15 or 265/50/14 on the rear but both of these really need 8" rims, which end up too big for the back (except on tonners).
Whenever I buy tyres with white letters it is easy to get rid of them, just face the white letters inwards!
