So, I'm not a stickler for price or originality and will research tire performance myself. What I'd like to know is what is the largest tire size that will "fit" comfortably on the car front and rear separately if need be. As a side note I have a set of the wider aluminum 14" wheels. Suggestions? My basic criteria would be "best handing" after the size. I'm tying to use size to alter the rear end ratio in an automatic car for slightly less RPM at highway speeds ..
Back in the day, Russell, a typical sports car/roadster like those from UK had 13" wheels. Some larger ones had 14". Some smaller cars had 12". The Minis of the era had 10". A large American iron car like an Oldsmobile F85 had 14" Even a 442 had a 14". The Toronado had a 15". Even a '68 Vette had 15".
Throw all that out the window today.Many if not most cars have 17", 18" or 19". Some more performance cars have "dubs" or 20".
The bottom line on that is that the older sizes ~14" are in short supply because of demand. They simply don't have the variety available. The best selection is going to be in the 17"-20" size and if best performance is what you are after...
SO: is it possible that a custom wheel with a larger diameter and lower profile might be possible? Might be worth a look. You'd have a lot of choices in 17-19". There's not going to be much in the 14" size to choose from. I have not idea who makes if anyone, custom wheels but somebody must.
OH ONE MORE THING: you might consider a trip to SEMA in Las Vegas at the end of the month...if you cannot find it there it probably doesn't exist.
