Yes, but with the additional height you will need to:
1) Make sure you have the clearance for the extra 2"
tire diameter if their is a fender over the tire.
2) If using on a riding mower you will have to adjust the
deck because the deck may tilt forward a bit so it doesn't
scalp the grass or cut uneven.
small
Why not. Should fit. same car.
That depends. Is it an actual "spare tire"? A tire of actual size. Or a "donut" tire? A smaller version of a spare tire. That latter is also known as a "space saver" tire.
Mini spares used in many cars for the spare tire. A smaller diameter tire that is narrow and harder than the regular tire.
Obviously Yes, spare tire can prove to be a life saver...imagine in a time of emergency your car gets punctured at that time your spare tire would save you!!!
Recommended should be in your manual or a tire store can look it up. If your spare is original & not a space saver, check the blackwall.
One could shop for a Food Saver Vacuum Sealer at retail stores such as Walmart, Target and Canadian Tire. Amazon has a variety of models available as well.
Same as car tire
Under the boot carpet! Should be a space-saver wheel or an alloy depending on how much you spent on the model itself
yes as long as its the same size
Not on the same axle.
Not on the underside. A full size spare would be too close to the ground to be practical.
