I'm going to order a set of original Bighorns. Should I go with 25x8x12 and 25x10x12 or 27x9x12 at all four corners? Is the extra 1" of chassis clearance with the 27's worth the extra weight? Will I notice loss of power if I go with the larger tire? I have the orange spring and a JBS sheave with 16gr weights---will I need to swap weights with larger tires? I had planned on 26x9 all around but they are on national backorder until late Dec and I can't ride until I get new tires. Another option is 26x12 all around but that seems like way to much tire for the front.

25's

I am running 25's and LOVE them !! I was gonna go w/the 26's like you're thinking...after talking to James about it (and taking his advice), I bought a good set of shocks (a second hand set of Elkas) to get my ground clearance...the big tires are just gonna wear sh$t out prematurely. I know a bunch will chime in and say they have so many thousand miles running 27's and bigger w/no bearing or brake issues...maybe, maybe not. Mine had 800 miles on it when I bought it w/a set of 27's (which I took off after about a week after buying it...it was a DOG)...at a little over 1000 miles, I was putting bearings in all 4 corners!! BTW...DO NOT buy cheap bearings...just wasting your $$...got less than 900 miles out of a set of All-Balls. If you do decide to go with the 27's, yes you do need to change od's . I have close to 750 miles now on my JBS sheave, I started out w/18's (running 25 'horns)...they did pretty well; but, my ride is pretty heavy (over 1650 lbs), switched to 16's, and I am VERY pleased now !!

how much difference did u notice switching from the 18 to a 16? I also run JBS and 18gr with OG 25 bighorns.

I was running the factory maxis rubber when I put the sheave in with the 18's. The 25 'horns are taller, and heavier...I noticed it wasn't quite as peppy after putting them on, especially on hills. We have a set of truck scales at work, out of curiousity one day, I weighed my ride....1650lbs w/out a full cooler (glass windsheild, steel top, tool box, rear bumper, etc), you don't realize how much all the add-ons weigh ! The 16's put the "wow" factor back into play...back to "roosting" in the mud; and, I don't have to mash the pedal as hard on the up hills...kinda feels smoother all the way around. The only thing...w/out the msd, the 18's would do 48-49mph on the level...I only get 45-46 w/the 16's. That is with the msd unplugged...there is no difference between the two w/the msd plugged in though. If you're a four seater, or heavy, I would reccomend going to the 16's .
