I see cars that have the wheel well practically totally filled.

Example: Nissan 350ZX. Large rims, low profile tires, nearly touching the fender. How do they fill the well so much without rubbing issues???

I have 18" rims on my xA with 35 series tires. I would like thicker tires (50 series) and wider (currently running 215s), but when I turn the front wheel, it appears that any wider or thicker would create rubbing.

I tried to look inside the well of the 350ZX and it doesn't appear that they bored out the inside or anything.

I really want to fill my wheel well more (not wanting to lower), but...

any thoughts?

Gap

 

are those stock tires on the 350 zx? how much deeper is the stock wheel housing? if the wheels are aftermarket, and much wider then stock, they might not even make sharp turns, I've driven several cars with wheels so big you could turn the wheels about 2 - 3 degrees

 

Ask Jon at 1TDA.com. He might be able to recommend something for you.

 

It also has to do with suspension travel. A Z is a "sports" car, so the suspension will be stiffer and not move up and down as much in the wheel well. xA's and xB's have more suspension travel so they'll rub more at the extremes.

A stiff set of springs or coilovers will limit the travel up and down, but lowering will put the wheel closer to the fenderwell. It's all about what the engineer designed the car to do. In fact, all the manufacturers know exactly what the maximum size wheel & tire are for each car they make. Of course, they won't tell us.
