You have plenty of clearance. There's a small chance it'll rub at the far limits of turning, but you can back off the wheel a little. You won't miss that ~1 degree of turning radius. Sizes vary between brands and even models of tires within the same brands, so you can't base your dimensions strictly by calculating the advertised sizes. But, calculating the advertised numbers, the OD of the 285/50-22 will be 1.1" taller, so it'll lift it .55"- call it half an inch. The speedometer will read 3.4% slower. So, 50MPH on your speedo puts you moving an actual 51.7. 60 on the speedo is actually 62.1, 70 is 72.4, 80 is 82.7...
