250es Front Tire Fitment Issue..PICS Added

[bigreddaddy]

I bought new rims/tires for my 250es. The guy who took my order called me back and said that he couldn't send me a rim for the front because it wouldn't fit right with the offset. I told him I was sure that it would fit since it is the same rim as the rear. But I didn't want to pay for a rim that he said wouldn't fit so I just had him ship the front tire with no rim since I had a good rim I could have it mounted on.
I bought two 25x13.50-9 super swampers mounted on itp rims for the rear. I bought a trail wolf 25x12-9 for the front. The first thing I noticed when they arrived was how WIDE the trail wolf tire was. It is wider than the mounted swampers. I took my front tire/rim off and brought it to a local mechanic shop to have the trail wolf mounted on it, and he told me my rim was too small for his tire changer. After telling him that the tire/rim I brought was mounted by HIM about a year ago, but he still said he couldn't do it.
ANYWAY, this is my question. Will the WIDE ass trail wolf lose some of its WIDTH when/if it is finally mounted on my rim??? 25x12-9 is the STOCK size for the red. I am also using stock rim size, 9x9. (By the way, I took an old REAR tire/rim and put it on the front and wholla, it fits just fine).

Well you have found out the unfortunate issues with atv tires. Even though they are the same size doesnt mean they will fit the same. I have seen tons of tires the same size be 2-3inches wider than others. I usually try to stick with stock front tire as I know they are skinnier than most and work great. If you do end up putting a fatter tire up front, make sure you air that sucker to the moon, to stretch it taller as it will rub your forks bad.
As far as the shop, most of the shops around here that mount my tires, do it by hand anyway. Their machines wont hold a 8-9" wheel. Unless you go to an atv shop, then thats the way they have to do it.

Well I finally got the trail wolf mounted on a rim and its fits pretty good. No rubbing. I also installed 2" wheel spacers on each rear. I think it looks pretty mean now.

i like it, looks good

Well my question is answered. Once the tire was mounted on the rim it loss some width and gained height.

Thanks man. All I need to do now is paint the racks, rear end and maybe the motor and exhaust.

I like the swampers. I was thinking about getting a set for my SX.

Very nice big red there fella! 2 Thumbs up for you. I am on the way tomorrow to pick me up another 87 big red and probably will be adding some nice aggressive tires on it too.

[bigreddaddy]

Thanks fellas. I really like how it looks now. I also have some stick stoppers on my parts bike that I'm going to put on it.

if your going to paint it and want to do it cheap, use the high heat stuff that you can use for your grill. holds up great and goes on with little sanding needed. last forever too

I know how much you lot love a stupid question, so...
Has anyone suffered a transmission overload faliure of any sort by having too much grip?

[McDerry]

How can you honestly have to much grip on a 400 pound 2wd bike. With 77:1 reduction in SL, the bike will flip over before it blows up something upstream of the rear axle.

Well, seen it done on a Moto4. Pinion and ringear shot pulling a tree out of a hedge.
If you're using the correct towing point on a Br., it's designed to keep the front wheel down using force transfer. The more you pull, the more downforce on all the tyres. Eventually something has to give and that 'safety valve' would be loss of traction. Tighten that saftey valve down and surely something else has got to give.

Its a low pulling point to keep the bike from flipping over backwards, it doenst add any more traction or weight to the bike.

Also take not of how deep the tread is on the stock tires. Those swampers don't have much more on the stock tread other then being self cleaning.


bevel gears naturally force themselves apart underload, down fall of the design.


its a 400 pound bike with a 17 hp motor and 5/8 depth tread. Your most likely failure will be closest to the wheels, being as thats where the torque has been multiplied the most. 90% of any failure in the rear end will be associated with a bearing failure. bearing failure tends to be a maintenance issue, or the lack there for of.
