Spare Tire Maximum Use Recommendations?
Safe-Saver/Donut Spare
These narrow, compact spares were designed to save space and weight in the vehicle. This allows the manufacturers to build a smaller car, but the tire itself is not built to last. Your owner’s manual will give the recommendations for driving time and speed. A general rule of thumb is to drive no more than 70 miles and no faster than 50 miles per hour before replacing your donut with a new tire.
The biggest reason to use these space savers for a short period of time is because they have little to no tread. This makes the spare vulnerable to road hazards and projectiles. It is also much smaller than the other 3 tires, making it spin faster to keep up with the moving car.
Over those 70 miles, the lubricating grease will break down, causing unnecessary wear on the gears and clutch plates.

Been on my spare for about 2 weeks now (!?) due to rim repair.
Hope to take it off soon!
