The tires on my beartracker 22x11x10 how big a tire will fit the rims with replacing wheels.

 

More or less anything you can get. It is wheelarch clearance that will be the limiting factor, don't forget the tyre is often close, on width, to the exhaust. I have seen quite a few bikes with shiny exhausts due to the tyre catching it. Also bigger outside diameter tyres alter the gearing, bigger tyres = higher gearing. If it is 4WD the front tyre outside dia has to match the OD of the back ones.

 

By measuring my tires on my 2 wheel drive Beartracker on the front I can go 6 "taller and 2" wide and will not rub at all, on the rear I can go 6" taller and 4" wider, stock tires are 22x10-11 rear and front tires are 22x7-10

 

Going with bigger tires is going to suck up all your power, once out of 1st or 2nd gear, your not going anywhdere unless going downhill!!

 

On my Timberwolf (the Beartracker's older brother), I know that 25's are pushing it, they're about 1/2" from rubbing the wheel arch. I would say 24" at the most if you want to keep it safe. But you're going to be giving up torque as mentioned above. The gearing on these guys with the 250 in them is set up for 22"-23" and they're already not a powerhouses or speed demon with those size tires (granted they were never meant to be...), so stepping up in size is only going to make that more noticeable.

Soon I'll be pulling my 25"s off and I acquired a set of 24"s for a heck of a deal that I'll be putting on my T-wolf as soon as my spacers come in (they're on some Honda wheels that had IRS, so they don't have the offset in the rear needed for the older solid rear end setup...)

 

Thanks I'm not a racer I ride mostly in the woods and putting along in 2nd or 3rd is fine. But don't want to give up the burst of power to go up the little short banks.was looking for a couple inches for the creek crossing. This is my first unit, I'm 69 just want to play some. Thanks again,


Lots of tire room but don't want to lose torque

 

If it's 4x4, whatever size you decide to go with, make sure you match the sizes in the front and rear (height that is). When I first got my 4x4 Timberwolf the previous owner had 24" on the rear and 23" on the front, which is terrible for the drivetrain because of the different tire speeds causing binding. Before I realised that's what the issue was, it was almost undrivable on pavement over 20mph or so because it would sway and wonder all over since the rear was fighting the front... As soon as I put on the matching 25" front and rear, that issue went away.

 

If you go to big, you might very well lose the piwer you need to climb the creek banks. You might get away with 24 but I would be xarefull with 25's. We used to own a Bear Tracker for the wife. ..fun little machine, great for zipping thru the woods on tight trails. Keep that oil and filter changed to keep her going!
