XL will have stiffer side wall than a standard tyre however, they are both radials but, will react differently over a surface, in a similar way a worn out springs or shock absorbers would react, if upu only changed one side. Firm vs soft pillow or mattress lol.
I need to get that box of screws out real quick lol Drives/steers real bad now Gonna get onto motorbility and see if I can get a matching pair
Even KrapFit in their information guides says you shouldn’t mix tyre type season load rating etc on the same axle!
