Hi Mike
Have been told in the distant past any trailer / ATV 4-stud with 8 inch centres is OK, but don't quote me.
The Funtech with skinny road wheels is alleged to be better for on road use than the wide knobblies. If you want to go wide on road, consider a wide road tyre such as Kenda Speedracers, more grip.
I have come across the question of putting wides on a skinny funtech in an old forum (not this one) and a couple of things came up. Easy one is you will need to fit wider mudguards to the rear to keep it legal as the skinny ones won't cover. Hard one is all Funtechs as far as I know have single rear hub bearings which are quite happy on skinny wheels, but fitting wides moves the wheel centres outwards and puts more strain on the single bearings leading to failure. The Sport 340, available later than the early Funtech, was simply an adaption of the Funtech achieved by fitting wider mudguards and sticking on wide wheels, but unfortunately it still came with the Funtech's original single rear hub bearing. I think I would be correct in saying that most rear bearing failures are on Sports. Secma did upgrade to twin bearings on later Sport 340 models, but I have no idea if later Funtechs upgraded to twin bearings at any point. If you stick wides on a Funtech, be aware of possible bearing problems in the future.
The Sport 340 wide rear tyres are 20 x 11 x 10 and the fronts 21 x 7 x 10. For those not in the know, the first number is tyre height, the second tyre width and the third is rim diameter in inches. So for example the rear tyres are 20 inches high and 11 inches wide on 10 inch rims. I think most quad bike wheels are pretty standard 4 stud 8 inch centres, if you're looking secondhand it might be possible to find some with the right tyres on. Make sure the tyres are E marked (legal for road use) if you're using them on road. If you're only going off road, it doesn't matter, any old tyres will do.
Good luck!
thanx for the indepth reply m8. i think u have just put me off doing that now : )

Oh sorry, Mike! Was only trying to help you avoid any problems. (Hangs head in shame, cheeks burning)

Permalink Reply by Albert on August 21, 2011 at 23:46 I have skinny tyres on my Funtech 350.
I have done 16,000 miles on them and they are mint, practically.
I don't think taking it off road is a good idea anyway with nobblies or otherwise.
It cannot do the suspension springs any good or the underworks.
I put my Funtech up every year and redo the underworks meticulously.
Otherwise there are all sorts of nooks and crannies in which rust can get a foothold.
I no longer venture out in it when it rains or on wet roads.
