Odd the 22" tires @ 9000 rpm go 54 mph while 25" tires @ 9000 rpm go 52mph. Makes sense though since a 500 H.O Scrambler goes faster with its smaller tires then a Sportsman 500H.O with larger tires.

Well, what that means is if the quad was traveling 52mph while locked in 4x4, the fronts would be pulling 54mph because the front diff is a higher gear.

Or, another way of saying the same thing is if the quad was traveling 54mph, the rear tires would be dragging at 52mph.

Whichever tires get the most traction. However, what I think might happen is the big 25 inch balloon tires expand at speed and end up being much bigger than 25 inches. So, the rears may actually keep up with the fronts at a certain speed.

 

Thanks for all the info, so to understand more than I wanted to ..lol

I can go with say 25's all around and it will not hurt the drive components it will just make the front pull faster in 4x4 mode and drag the rear on staights in 4x4 but when in 2 whl drive it should not effect anything? is that correct thinking?
thanks

 

That is correct.

With 25s all around, the back tires will go 52 mph and the front will go 62. In 1st gear superlow at 9000rpm, its 5.43 mph rear and 6.4 mph front.

 

Thanks

If it were you would you do 25's all around or would you keep it 25 and 22?

last question on the tires for size anyway ..lol promise

I was asking myself that same question. I don't know what it would be like with my front spinning THAT much faster than the backs in mud. Would I still be able to climb out of ruts? Would it be even easier? I just don't know. Never been there. I was hoping you'd tell me after you got them. [img]i/expressions/face-icon-small-happy.gif[/img]

At the least I would get bigger tires than the 25/22 combo. Maybe the 30/26 or 30/27 or something. Or 27/25. I don't know. Find the kind of tire you want and figure out what sizes they have that fits your rims. That's sorta what I was doing before I just gave up on the quad altogether.

Really though, in 2wd mode, and for the best handling, you want bigger tires on the front. Dirt bikes, race quads, even race mountain bikes usually have a bigger front tire than rear. On my quadsport I put 23's on front and 20's in back. It just works better.

Oh I don't care. Its a nice break from work to discuss interesting things. Make the thread 100 pages if you want. [img]i/expressions/beer.gif[/img]

 

I think I will try it if I can find some used 25x8x10 cheap if it works out good I will buy new but will let everyone know the outcome.

So if anyone has a pair of used 25x8x10's I am interested

thanks

JB, that is not correct. I have the machine outside. It has original tires. I know the backs are 25's for sure. Also, I have the service manual. Also, rockymountain says 25's. http://www.rockymountainatv.com/vehicleFilter.do Maybe you're confusing some other quad?

Could be. I just took a walk out in my back yard - (my OEM KQ300 tires have been used for years as a paintball barrier by my sons and are still out there). 25's on the rear and 24's on the front. While I've never owned an LT250, I do remember comparing the 250 vs the 300 on the showroom floor and remember the tires on the 250 being smaller. Tire size was one reason I preferred the 300. Could be I was just remembering the smaller fronts.

It's also possible that the"stock" tires were a dealer swap. Back in the early 90's, Suzuki used Dunlops as OEM tires.

In any event, both those Suzuki's are set up for a smaller front tire diameter than the rear. Switching to the same size tire front and back can be done and in most cases will not make a noticable change in handling. But there will be a difference in rotation speed between the front and rear tires when in 4wd.

Yeah, according to my manual, the 300 had 24 fronts.

One thing I liked about the 250's is it has the same piston as the 230 quadsports. Which means you can put a big bore kit for a quadsport on a LT4WD. [img]i/expressions/face-icon-small-happy.gif[/img] I think it ends up being the same displacement as the 300, but 50 lbs lighter.
