Sportsman tire sizing..Help....
#1
Have a '99 335 and was wanting to go 25" all the way around. It currently has stock 23 front and 24 rear. I heard it may mess up the 4WD...but I think the 2000 models have 24's all the way around. If 25's won't work, I'll go 24 front and 25 rear. Probably bear claw or that new GBC tire. Also, will this hurt the speed/performance??I'll surely stay away from Titan. Any suggestions/help is appreciated.
Thanks, Drew

Subtle differences between stock and newer tire diameters won't make a mess of your quad unless you plan on doing a lot of 4 wheeling (AWD) on pavement or really solid turf. Soft ground, sand or mud should not mess up anything in the architecture of your drivetrain while engaged in the AWD zone.

Padzz,
The gearing in the tranny that spins the front and rear shafts is setup to accomodate different size tires in the front and rear. The front hubs spin faster than the rear hubs because the front tire was intended to be smaller. If you make all 4 tires the same size then the fronts are trying to spin faster. On soft ground this MAY never case a problem. On hard ground it will strain the drive train (only when AWD is selected and engaged).
The AWD front hubs are mechanical in nature and engage only when the rear wheels spin faster that the fronts (and the AWD switch is on to provide power to the AWD coils). Playing with the tire front/rear size ratio will have an effect on when the AWD mechanical hubs engage.
To an extent I agree with SWAC1. Mild tire size changes will not affect things, as long as the ratio of front to rear remains roughy the same. ie, do not make them all the same size. If you go up a size in the rear, go up a size in the front (not two sizes).
Remember, the bigger the tire, the harder the engine works to turn it. There will be a difference in power output.
