Thank you to all the Ridgeline owners that have posted to this forum. I have found the information interesting and helpful.
Joined 265 Club.
My first posting for a 2017 RT Sport G2.
Installed 265/60r18 XL Nitto Terra Grappler A/T G2 tires. The XL (extra load) tires are a better fitment than the LT E rated 10 ply all-terrain tires. The LT tires for this size can weigh 50 pounds or more for each tire. The Nitto TG 265/60r18 XL weigh 38 pounds. The original tires Firestone Destination LE2 245/60r18 weigh 33 pounds. Therefore these Nitto TG's in the larger 265 size add an extra 20lbs below the vehicle's suspension (reasonable) whereas an LT tire such as the BFG KO2 in this same size would add 68lbs below the vehicle's suspension (unreasonable in my opinion, but certainly do-able and possible).
The Nitto TG's G2 add minimal road noise, nothing that you might notice, especially if you were not paying attention to the noise, or had the radio or stereo on. I have these XL tires (max pressure 50psi) inflated at 35psi, some people recommend 41 psi for this XL tire. The ride is now a bit stiffer due to reinforced sidewalls in the XL tire, I do like this feel, as it feels more truck like. I did find the original RT G2 ride too soft for my liking, too car-like in my opinion, however a type of ride which some other drivers may certainly appreciate.
I should also mention that I do have the Truxxx 1-1/2" leveling kit installed which nearly eliminated the front-end rake of the 2017 Ridgeline. A very good decision in improving the aesthetics of the truck. I mention this though, because I would certainly recommend the 265/60r18 tire size for the truck (the largest tire I believe this truck can accommodate) but keep in mind I do have that 1-1/2" front end lift. With the 265/60r18 Nitto TG G2 XL tire I still have an inch of space between the tire and the wheel well, even at full turn. I can place my hand around the entire tire with my hand when checking for clearance.
Keep in mind this tire size may affect the reading of the speedometer and odometer when measuring road speed and mph. However it is only affected by 3%. Driving 33 mph, off by 1 mph, 66 mph off by 2 mph, and 99 mph off by 3 mph. I manage and evaluate this difference by believing that automotive manufacturers calibrate their speedometers by running them a little "hot" to avoid liability, therefore the 3% difference between the 245 and 265 tire makes the speedometer more accurate.
Other modifications and accessories, Weathertech floor mats front and back fit perfectly and look sharp. Powder coated brake calipers. Retrax Pro MX tonneau cover (matte black).
I would certainly recommend the Retrax Pro MX tonneau cover. It looks sharp, and operates well. My plan is to place the drain tubes from the canister when I get the BedRug mat on order, which is expected to ship first of the year 2017.
I do recommend the the Retrax Pro MX if you don't mind giving up a foot of cargo in the front end, still some space under the unit. The truck is utilized in our household as a sport utility truck, and not a work truck. Secondly, keep in mind the under bed trunk cover lid will be restricted to some degree. Do your own research to determine if acceptable. My son, whose truck it belongs (nice dad) was disappointed at first with the lid restriction and the partial loss of light from the cargo bed side wall light. However after getting the unit installed and using it, he loves it. You can still reasonably access the trunk with the tonneau cover even closed, placing and taking out groceries. Also you will get another 5 inches or so if access when the tonneau cover is pulled back. I plan on perhaps wiring a light into the trunk (not necessary) and also purchasing a Dynolock or Pop n Lock aftermarket tailgate lock (remote controlled by key FOB) to fully secure the truck bed (necessary).
The Retrax Pro MX could possibly be designed with bed wall cap flanges that mimic the Ridgeline aerodynamic design, a liitle odd at first, but definitely get use to it). The Ford F-150 has the same aerodynamic issue. If you want a tonneau cover that sits inside the truck bed walls with a "square" flush look, consider the BakFlip tonneau cover expected out in January 2017. I straddled between these products, but decided on the Retrax due to overall durability and expected longevity of the product. Although I do believe the BakFlip appears just a bit more sleek, but you needed to fold it up for truck bed access. Lastly when you want full access to your bed you need to fold the BakFlip against your rear window, obstructing your view. When exactly do you want a full unobstructed view of your bed? Yes, when your truck bed is full of stuff. I am happy with the Retrax, but I suppose I could have been happy with the BakFlip product just as well. However, I would have become disappointed with the product down the road when it began to deteriorate. This Retrax Pro MX will definitely last the lifetime of the truck.
I will attempt to add some pics (couldn't figure it out, so pics are in Ridgeline "Garage" gallery).
I think most Ridgeline owners will appreciate how the 265/60r18 tires fill out the wheel wells. So with the leveling kit adding 1-1/2 inches and the tires adding 1/2 inch to the height of the vehicle, I now have the truck sitting a full two inches higher, and leveled. That may not seem like a lot, but the truck now looks like a truck, and I am happy, and so is my son.
If there are any questions I will attempt to answer them over the next two weeks.
