I have recently re done my suspension, sport springs etc. I have the beautiful Alfaholics GTA style rims, (15"). In the correct offset. My question is what size performance tires will fit?
Generally speaking, Alfa's preferred oem wheel offset was always greater than 30mm. The Ti Super Campgnolos were, I am told, about 38mm which is what the 15x5.5 replicas sold by Classic Alfa are (that is also, again I'm told) what the 15x6 Japanese Autoparco replicas are. That would make sense because the Alfa engineers would have been aware of the rear rubbing problem and would have compensated for it by moving the wheel center inboard as much a possible. It's axiomatic that, with that much offset, you'll have less rubbing problems than with wheels with 30mm or the 28.9 mm offsets of the GTA 15x6 replicas I'm running on my Super. With this in mind, it's no wonder the stock seel wheels with substantial offsets and 5in rim widths work so well. They were designed for the cars!Alfa did offer a 15x6" wheel (with tang) as an option for these cars. 105.02.28.010.00 optional on Ti, Ti Super, Super. beyond that, i have no clue. if anyone has any info on offset for that wheel, would appreciate it.
As I mentioned in my earlier posts, something to consider is the health of your suspension bushings. While my Super doesn't exhibit any pronounced worn-suspension wobble, the rear suspension bushings are nonetheless worn just enough to cause enough lateral movement of the axle to cause some rubbing under load.
As is often the case, not recommended by the manufacturer, but you can get away with it.Yes, Very Interesting!
I didn't know a 185 tire would fit on a 7" rim. I guess hard but doable.
Yep good one.My other question is: Are these Pirelli's New modern tires with modern construction and compounds or are they just replica's of the old tires using the same compounds and construction as the old tires? I ask because I am assuming that tire compounds and construction has moved on and advanced since they were making those old Pirelli's. Or am I wrong on that front?
