Spare tire

djphill · 07-07-2008, 12:28 AM

I no it might be a little risky, but do you think it would be worth it to drive without a spare tire. The reduction in weight could help mpg, probably not by much but any increase that is at least over a couple mpg's is good.

This thought has crossed my mind a few times. I think i may do it for local driving, and put it back in for longer trips seein as i didnt renew my AAA

does anybody know how much of an impact this will have on mpg

Well some people did that for performance reason.
Assuming that the spare is 20lb, you are looking at 2/3 of 1% reduction in weight,
which is 0.4mpg assuming 60mpg as a base line and mpg proportional to weight with small delta. Carry a plug kit instead if you really want to get rid of it.

In real terms that is a theoretical saving of 0.03 litres per 100km, that is every 100 miles you travel you will save a massive 0.048 litres or 1.62 fluid ounces or 10 teaspoons. or every 7,800 miles you will save a gallon of gas. All this just for being stuck, helpless on the side of the road for an hour or more.

Or you can have a spare tyre in the back of the car in case you get a flat tyre.

that way, putting everyone on a diet will also have an impact on MPG...

... or you could avoid one hard brake application per day.

It would make getting in and out of the car much easier and ease working on the car.

It's not worth the risk for a return of almost nothing.
