    Wondering if anyone is running this size on a stock lift for 09 xl. I have some new to me escalade 22s and would like a bit more sidewall. Looks like there's enough clearance but want to make sure here first. I have stock air suspension if that matters.

    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...

    Regarding wheel/tire combinations that will fit your truck without rubbing, no 2 trucks and their suspensions are exactly alike, due to a number of factors including accumulated wear on the suspension components, so there is no guarantee that what fits with no rubbing on one truck will automatically fit with no rubbing on your truck. Other folks' experiences can guide you in one direction or another, but the final test will be when you mount the wheel/tire combination on your own truck.

    To assist you in getting a good idea on whether or not specific alternate wheel/tire combinations 'may' fit your truck with no rubbing, I recommend that you use the wheel/tire comparison app at the URL listed below. You can use this app starting with your existing wheel/tire combination as a benchmark, assuming that there are currently no rubbing issues with it, and measure the actual critical fender and suspension component clearances as directed by this app. Then, you can enter alternate wheel/tire combinations, and this app will give you the projected changes in these critical fender and suspension component clearances.

    I used this app for determining whether on not I could use my current alternate wheel/tire combination, and it accurately projected the changes in critical clearances. Again, the use of this app in not an absolute guarantee that an alternate wheel/tire combination will fit without rubbing, but it provides a much better assessment, or projection, than simply an educated guess on your part, or a statement from others that it worked on a truck other than yours.
