I have a set of original Bighorns and I am exploring new tires and ran across Bighorn 3.0's. They seem to have been around for a couple of years but I can't find much about them. Only one review on the entire net that I can find but other than that, nothing more. Is anyone familiar with these tires that can tell me the good and bad about them?

Thanks!

Your right not much real time info, 26x11 is almost 29 lbs I'd pass on that and the price alone.

I hear you there!

Very new to this and have only gone out 5 times so far and I really need some advice.

I bought a 2006 660 with a thrown timing chain and bent valves. Other than that, it was in great condition and it only has 300 hours on it and since it is my first SxS, I decided to just repair it and do minimal engine mods in case I didn't enjoy it. I changed to a 9.9:1 piston and a Stage 1 cam. It runs perfect and after the first time out, I was HOOKED!!!

The issue is tire size. After the engine repairs, it was hitting the rev/speed limiter at 38 MPH and it felt like it had a lot more than that so I put a CDI, Sheave and clutch kit and now it does 48 without hitting the limiter (speeds based on GPS, not speedo).

The previous owner had just installed Bighorn 27X9RX12 tires on it before it broke. These are Original Bighorns that are actually almost 28" and needless to say, these tires are just too tall and heavy for what I have. Bottom end is horrible and it takes almost full throttle to get up the steeper hills and starting on a reasonable incline is almost impossible and feels like I am going to fry the clutch or break something. I need my lower end back!

My delemah is what size to use and what sacrifices I am willing to make. I am torn between going back to the 25" factory diameter or stepping up to 26" tires. Here are my concerns:

1) Speed is not an issue, I am not skilled enough to go fast but hitting the rev limiter (which i did that first time out before changing the CDI) makes my stomach turn for some reason. I think I will hit the new (higher) rev limit with 25's, that is why I am considering 26's.

2) Bottom end is my main concern, that is why I am considering the 25's.

3) Ground clearance is a concern and the front springs are shot. It is sagging badly (only 11.25 clearance with the 27's and the preload all the way up) so I am replacing the springs to get it back to factory height. I AM willing to install a 1 or 2 inch lift after the springs are replaced if needed but nothing more than that.

Maybe I am just putting too much thought into this but I don't generally throw parts at something until it suits me and I hate spending money without a little knowledge and insight from those that have possibly been down this path. Any thought from the members here would be much appreciated.

Thanks!

If you don't have a machined sheave I would call Todd at Hunterworks a vendor on here, he will talk you thru the setup your looking for. I run 26x9x12's A043 SunF on all 4 corners, orange secondary spring, 18 gram weights and a slug kit 42 mph top speed and runs easy at 30 all day long.

27" tires will rob your bottom end , even with a "built" engine....a clutch kit will help drastically to return most of what was lost . If all of your clutching is stock , do a google search and read reviews from the different options out there .

Thanks all for the replies!

I guess I must have included too much info in post #3 so no one read it through because as indicated, I already have a slightly built engine, a "modified" sheave and a clutch kit. I will be a little less wordy this time.

Google searches are all over the place and the information is confusing because one person's expertise/experience negates the next person's expertise/experience so I decided to buy some $10 used 25" tires and test for myself.

Here are my findings if anyone else is remotely interested...
This is on a 2006 660
Engine is all stock except Wiseco 9.9:1 Piston, Hot Cams Stage One and a 700 Chain Tensioner.
MSD 4240 Charge Speed Enhancer
EPI WE365090 Sport Utility Clutch Kit
Black Rhino Modified Sheave
Dayco XTX Drive Belt

With BigHorn 27X9X12. Top Speed 48 (maybe 50 but that was once going slightly down hill). Bottom end suffering badly.
With $10 used Bridgestone 25X10X12 as a test. Top Speed 49 (I was shocked!) and still not hitting rev limiter. Bottom end is much, much better!

Needless to say, I will purchase new 25's for it ASAP.

Ok , let me re-word...a clutch “kit” (which you have) will not give your bottom end back...you need a machined sheave. Like I said before , do a search...if I type my recommendation it will get deleted.
