Will 235/45/17 fit on an ar? What are the trade offs?
I love the stock wheel that us used on the 17" Audi a4 and I came accross a set of 4 on e-bay with only 100 miles on them. Any advice on this? Adapters/specers, etc.

Stock size 225 x 55 x 17".
Plus Zero size (i.e., statistically ideal [close enough for jazz] to maintain the "accuracy" of anything related to the turning of the wheels (e.g., speedometer, odometer, the computer, etc.)) 245 x 50 x 17".
Why would you NOT simply plus zero, remain the same or plus 1 (which I realize costs a whole bunch more since new wheels are required)?
Someone who knows more about this stuff than I, should comment on the "trade offs" that going to a tire that is this far outside of the oem tire's circumference could cause.

Downsides:
not the correct diameter - too small. therefore speedometer will be off, fuel consumption higher (more revs at cruise), louder/more revs at cruise, less sidewall for impacts/potholes/offroad use.
advantages?!? Perhaps stiffer handling, better acceleration due to reduced gearing.
Bottom line is that it is not the right tire.

To expand, rolling diameter is 5.3% smaller.....
This will cause potential issues with ABS, etc. It will also mean your speedo and odometer will be off by 5.3%. So:
-Your speedo will be off my 4 mph at 70.
-When you have driven 50,000 miles shown on your odometer, you will have actually only covered 47,350. In other words, you will end your 4/50 warranty prematurely by 2,650 miles. And if your car is leased, say for 4 years/ 48000 miles, you will be off by 2544 miles too many incurring a charge (.25/mile iirc) thus owing $636 you shouldn't have to pay.
I wouldn't use the tires for very long... too many down sides.
