Polaris 570 Bighorns install
 

Do I need wheel spacers for my 26" Bighorn tires install?

Also what should be the PSI for front and rear tires?

Thanks,

Whether you need spacers or not depends on the width of the tires. 26" diameter shouldn't cause any clearance problems if they're stock width.

I think they are, is it 5 PSI on the tires?

Tire pressure is going to depend on application and just which bighorn you end up with also. 5 is a good place to start on an atv, maybe double that for a sxs.

Should be fine without spacers and 5-7 psi should be fine.

Good info everyone. I assume the stock tires are also the same PSI? Any better setting for us bigger guys going on Hatfield McCoy trail? Lol

Check owners manual but probably in that range on your 570's stock tires. Too much/at the top of the psi range will make for a less forgiving ride and less grip over obstacles. Too little and you risk coming off the bead unless running beadlock rims.

5 psi is what I run on just about any tire I have ever used. Good combination of ride and traction at that setting. I'm 205 lbs myself. Most tires are fine down to about 2 psi without coming off the rim. If you're a bit heavier rider, 5 psi should still be more than sufficient. The only issue in that case would probably be trying to go too low like the 2 psi lower limit. A few extra lbs of rider or gear would probably result in the tire popping off at extremely low pressures. At 5 psi, all should be fine.

I always air up my stock tires to 5 psi like it says or 5.5 and it seems to work okay. I'd start their with aftermarket tires too.
