Most 1st gen apps with 18x10's run around a 5.5" BS. With that tire size, I would not run a 10" wheel. A 245/50/18 has a section width of 10". A 10" wheel actually measures 11" wide. By the numbers your tires would be pulled in .5" on each side. Given you would run the typical 18x8 with a 245/40/18 (~9.7" width) up front, you would have around .3 to .4" sidewall bulge up front and -.5" out back. I will look goofy. If you want that 245/50 out back run a 18x8. Or......safe yourself hours of homework and run a 18x8 w/ a 245/40/18 up front and a 18x9 in the rear with a 275/40/18. Depending on your brakes and the wheels brand you go with, you can play with the rear pad lengths to give yourself more wheel lip to make up for the 9" rear wheel hoop. Give Jon at Driverz Inc a call and he will dial it in for you.
