The tires are 245/30/22. Perfect size for 22"s on a Cutlass. You don't really need to lift it. I put in air shocks and we had to trim the front fenders very slightly. And no, the rims aren't cross-laced. Just regular 150 spoke wires, nothing special. As far as cleaning them I just spray them with Purple Power degreaser and then just use a brush with soap and go over them. If you clean them regularly they're easy to deal with. If you go months without washing your car then you'll have to do some scrubbing. And I agree with all you guys as well, I love wire wheels, more than any other big rim but I always run in to the same issues. Leaks!!! Right now 3 of my wheels are leaking air.
