First time on site. I have a 1986 Fourtrax 350 And this is a great site.
I thought I come on this column instead of the tire column as I see i might get a better response .
Anyways as we all know these quads come stock with 24x9x11
Finding used tires for a 11 inch rim is nil.
Finding used tires for a 12 inch rim are in the pages on kijji

I found 4 new take off tires on rims that were on a yamaha rino 25x8x12
I thing going narrow is better as i will get less mud fling past the fenders.
Hight will only be 1/2" that no big deal.

But will these rims fit my 86 Honda ?
Anyone try this tire size.

Also found many 25x8x12fronts and 25x10x12 rear Anyone try this set up on a 86 fourtrax 350
Thanks
