looks like it should solve the issue-- I would add to be aware of watching for the tent to perhaps sagging a bit as you ride, or going further down than you'd think over big jolts--so play it safe either with a strap to raise that part of the tent bag a bit, or along with a strap, put a bit of plastic in the "potential tire rub" area (like cut out a bit of car windshield wiper fluid bottle or something) in case the occasional rub could happen.

I've seen folks not noticing a front bag that has sagged and getting an abrasion rub / hole happening. You really don't want that going on with a brand new tent.

and as for last minute-- you are not the only one guilty of that.....
