Old syko is right about the Titans being heavier than most OEM tires. Thats one of the things to consider, however the tire is heavier for a reason and those much thicker tires, sidewwalls included, work great for me, since I tore the sidewalls out of the originals pretty quickly. If your fourtrax displacement is 250cc or higher, the heavier tires won't be much of an issue unless you are racing and don't want to lose a split second of time. Good luck.
