'89 Metro - Has 13's... go 14's or bigger?

[ebacherville]

Not a metro but simular.. I'm looking at going from 175/70-13" to 155/80-15's.. or 165/80-15" this is the old school beetle tire size.. there somewhat hard to find.. not going to find them in stock in the local tire store.. so you got to order them. For me they will lower the rpm at speed and thats what I'm going for as my CRX HF apparently has the CA transmission and I'm doing extreme areomods that will lessen drag considerably.. However it looks like ill need to use aluminum after market rims to get this to work. as I cant find any 15" steelies with a 4x100mm bolt pattern.

hey gents... are there any aftermarket lugs that fit the studs used for my 12" wheels but that work better with the 13" wheels? i've read from a number of you that the stock 12" lugs are a wee bit small for the 13" wheels.

suggestions welcome! my 13's should be here in a few days!
