What tires do you have right now? Do they rub at all? What gears do you have?

The tire you are looking at is approx. a 33" tire. From the stock 29" your speedometer will be around 15% slow as well you will drop gearing a fair bit. For example if you have 3.73 gears with the tire change you'll drop to about a 3.30 ratio. The larger the tires, the less seat of the pants get up and go you'll have. As well, larger tires put more stress on bearings and steering/driveline components.

The 140HP of the 3.0 is going to seem like 90 or so when it comes to getting moving. Not a problem if you drive it right but, inexperience will toast a clutch, or snap u-joints and such.

Pretty much for every 1" larger tire over stock you will drop .10 in gearing. That directly affects your acceleration and ability to off road effectively.
