Do not know from when to rise, people began to advocate the spare tire away, but difficult to use, simply lose weight, save oil!

It is understood, large diameter wheels is a current trend, especially some high allocation of vehicles, like big wheels to create momentum. The big wheel flat than is generally small, mean fetal wall is thin, in the face of the severe impact, will increase the risk of tire. With our long measuring vehicle as an example, last year on the Citroen C4L, Cadillac XTS encountered tire was on the spot to scrap the situation. If the burst occurred when a long distance, the village could not before the shop foot hopeless, high speed "Super Trailer" in the news has too many. Unless the walk in the home near the day only, and family can give you promptly sent spare wheel over, or remove the spare wheel is a great risk.
So, little spare tire? In fact, the public also often early with a small spare tire, but later in order to conform to the "public opinion" and stop using. As for the European luxury car, even some models have been made, but the localization process generally is slow, it is still small in the spare wheel "". Small wheel due to size is narrow, can effectively increase the height of the trunk, another benefit is to reduce weight, with slightly lower fuel consumption. However, little spare tire has a biggest disadvantage is speed, lower grade, width is very narrow, and the left and right wheels of different widths, the running speed is generally not more than 80km/h, while also careful to control the driving range of motion.

For a full size spare tire, to specific issues, specific analysis.

As for the explosion-proof tyre, the brand is not much, BMW is one of the most active. In fact, "explosion-proof tyre" is a misleading name, more accurate translation should be "tire", is to use the side wall is hard, tire even cut, can also use the side wall support. Explosion proof tyre is actually a very good solution, in addition to "destroy" the occupied space of the spare tire, in terms of safety but also be of great advantage. When the tyre was scratched, explosion-proof tyre won't appear suddenly deflated, the high-speed burst out of the probability can be reduced greatly. In addition to sell at a higher price, explosion-proof tyre the promotion rate is low because of the sidewall is hard, have great influence on the comfort.
