Hello all,
Two days ago I purchased a Ridgeline RTS. It has been a wonderful change from my previous car. I had an '02 Wrangler Sport (TJ) that was on its way out. My Ridgeline is a huge improvement over the Jeep in all but one regard... off-roading capability. But I don't do too much crazy off-roading these days. I have a 19 foot boat and the Ridgeline handles like a dream while towing it.
When I first set out to purchase a compact truck I went on Consumer reports to look at the Toyota Tacoma, which had pretty bad reviews by the way, and noticed the Ridgeline for the first time. It is the top rated compact truck and voted overall best truck in Consumer Reports. I test drove the Tacoma and wasn't overly impressed. Right afterwards I headed to Honda to test drive the Ridgeline. From there all it took was one test drive to realize that the Ridgeline really was amazing. The dealership was nice enough to bring one of their demo trucks over to my house so I could test the truck out while towing my boat. After that I was sold.
One thing I would really like to do in the future is get some different tires with better grip. My driveway is wicked steep and traction is poor. I found a tire that I think might work: BFGoodrich All-Terrain T/A KO (LT245/70R17/E 119 R). The diameter is slight larger than the stock tires (approx. 1 inch); there should be plenty of room in the wheel wells. Any thoughts, opinions, or past experiences that might shed some light on these tires as a viable alternative to the current tires would be greatly appreciated.
Aloha, Dave

Welcome to the ROC. With what you said about the Tacoma it just makes me happier that I made the right decision buying a Ridgeline just a couple months ago

Hi Dave and welcome to the ROC.

Regarding your tire choices, here is a thread with a nice chart that one of our members put together. Could be one of your neighbors if you are in Hawaii.

Be advised that larger diameter tires will lower the effective gear ratio and may adversely affect your towing performance. It will also throw off your odometer and speedometer.

Here's a calculator to see how the tire size affects gearing:

For example, going from a 29.5 inch (OEM) tire to a 30.5 inch tire, using the RL's final drive of 4.533... the new tire yields an effective final drive of 4.38.

I'm not seeing this. I know a taller tire would influence gear ratio, but how would a wider tread do that? Hard to see the physics here.

Larger diameter = taller... not necessarily wider.

Thanks for the info, that helps a lot.
