Tire stuff -Mixed Spare tire- will it work

Recently we bought a new Itasca MH on an F53 chassis with GY G670 RV tires. Itasca doesn't crank out rigs in this model line with spare tires.(245 70R19.5)

Having had a Class A a few years back that seemed to enjoy blowing tires or having tires that fail, I want to always have spare handy- especially since we are running up the Alaska Hiway this coming summer.I recently purchased a wheel to mount a spare on this new rig.

My mind is saying to me don't spend big on this spare- just get something to get you to the next spot where you can have your G670 repaired or replaced. So I have been eyeballing a Sailun S637 which is significantly lower cost than a GY.

I see a bunch out there on these Sailun G670 tires for 5vers (smaller diameters) but not much about them for MH's.

Is this a practical tire for a MH spare? Any big issues with running an odd tire for a while until I can replace something in kind if I lost a GY G670 assuming same load range?

Do these tires work well permanently mounted?

Would appreciate some outside thinking guidance here about this.

Thanks

Anything will work for a spare and I was able to purchase two Hankooks and have them mounted right on the the NY State thruway this past summer for a very good price. While you're paying for a name, I would question the GY 670's as a contender and while you're losing so many tires, are you providing enough air in them and at least 10psi above what the inflation chart is calling for and according to the axle weights of your coach. After that, all you can hope for, is avoiding a road hazard of some sort.
