Re: Narrow vs. Skinny
There are a few types of terrain where a skinny tire is advantageous (where you want your tires to dig down deep), but for 90% of terrain, I believe a wider footprint is better. Part of what makes a Samurai go so well off-road is that it's so light; it just floats on top of whatever the surface is. I've always used the analogy of wide tires being comparable to the tracks on a snowmobile or a bulldozer.
It is for this reason that I chose 33x14.50 Swamper SSR's to drive on, and I have a lightweight 33x9.50 as just a spare to save weight but have the same diameter (I'm locked front and rear). For the last 3 years I have used 33x12.50's, and I've tested these new 14.50's in terrain ranging from pavement, snow, mud, sand, and rock. The wider tires have outperformed the 12.50's in every terrain type, allowing me to go places that I've never been able to go before. And even when trying to spin my tires, I'm usually unsuccessful. These tires refuse to let loose!
