When we purchased our new to us coach, there was a 4 month old un-mounted spare tire in one of the compartments. I didnít like the 22.5Ē tire taking up the entire cargo compartment, so we purchased the Roadmaster spare tire carrier. It is designed so you can lower the tire (and raise the damaged one) back into the travel position with one hand, although I typically use two. You can lower to either side as well.
I purchased a used rim from our local tire dealer for $20.00, had him mount and balance it, and repainted the rim so it looks like new as well.
I like the idea of a mounted spare as my ERS will exchange tires free or really ďpre-paidĒ since you purchased the ERS, but will charge for mounting your un-mounted tire.
I am probably more likely to end up offering to let some other coach driver use my spare than needing it myself, but if nothing else, it is peace of mind.
I also have a torque multiplier for removing and reinstalling the lug nuts, and jacks for jacking up the coach, but would more likely just call ERS if I have cell phone reception.
In addition, it is possible that the rim may be damaged in the event of a catastrophic event as well, so mounting your spare tire on a damaged rim isnít in the cards, at least for me.
To carry a spare or not, no wrong answer to this, I just decided to carry. Iíve got better things to do than sit on the side of a road on a Saturday night, until Monday morning, waiting for Billybob to sell me an off brand, incorrect sized new or used tire for more than I paid for my carrier AND the tire! Or let someone with the wrong equipment tow my rig and damage the generator slide out because they didnít know what they were doing . . . . Your mileage may vary
