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
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.
k thx i guess i'll keep it but does anybody know any other positive affects it could have except for getting a little extra space (that i don't need).
Keep in mind: a plug kit will NOT work on sidewall punctures. Also, do not use a can of fix-a-flat, it'll destroy the TPMS sensor.
One good thing, if you don't have a mobile phone it could lead to more exercise (while you walk to find a phone) therefore better personal fitness! Does that do it for you?
You guys are tough! anyway, Have you tried P&G, warp, or highway warp yet? Cruise Control doesnt help me very much on the rolling hills of the interstate.
According to this article, reducing weight by 120 lbs will improve fuel economy by 1%: Auto components lighten up to improve mileage - USATODAY.com
Is the spare (& jacking equipment) near the rear - if so its good to have a little more weight in the back (helps handling characteristics) + like others have said you paid for it and may come in handy.
