285x75x17 BFG KM2's
Last week I fitted the 285x75x17 BFG KM2's with 1.25" spacers.
First impressions:
They are a little more noisy than the stock KM1's but less noisy than the 35" KM2's we had on the 08.
They rub a little at hard lock. Probably should have gone with the 1.5" spacers but I was trying to keep them under the fenders.
I did notice a little loss of power on the highway but nothing compared the the 08 which had 35's and 4.88's. I cannot say enough good things about the new engine and transmission. After installing the larger tires it did downshift twice pulling the same long hills that we pulled a few weeks ago with the stock tires. This was not a bad thing though. Unlike the 08 which would start wailing like a banshee and still struggle to hold its speed the 2012 would quietly down shift into 4th and the speedo wouldn't move.
At this point I don't see any reason to regear. It is still turning around 2600 rmp's at 75. Once I get all of the weight of the bumpers, winch and cage on I might reconsider but for now it still out performs the 08 hands down.





You'll notice I did added the factory steps. For me they seem to get in the way as I have to lean over them to put my butt in the seat. I can't imagine they would afford much real protection as they are plastic but they do help with rock chips on gravel roads. It was a last minute decision and will probably get changed / improved. We were taking Brandy's 83 year old grandmother over into Arkansas to see the fall foliage.
