Not sure about other suppliers, cos I was looking originally at 315/75R16 - and found not that many suppliers did these.
Not sure what size rims Zu have, but for these tyres (315/70R17) hankook recommend an 8.5" wide rim. For 315 width tyres generally, mfrs tend to state rims in the 8" to 10" range from what I have seen looking around on-line.
I don't suppose you want to sell your old wheels? I have got drum brakes on the rear, does anyone know what alloys fit with the least amount/no modifications?
The problam isnt the rears the alloys will fit the rears no problem its the fronts they wil foul on. Trust be been there got the t shirt. its because you have the deep type drive members and the front drive member fouls the inside of the alloy the rear 9 times out of 10 fit no probs. Drum braked motas have the older deep type drive members/hubs/stubs and that is why they say drum brakes is a nono for alloys.
Some do fit and some do not there are spacers on ebay about 8mm spacer ring you can use but its not advisable and u will need to check your nuts regularly.
