Polaris ATV Maintenance & Repair Tips : How to Check ATV Tires

On behalf of Expert Village my name is Tom
Roland and we’re at Cottonwood Motor Sports and I’m here to tell you about doing a service
on a Polaris Quad and this is fairly representative of many of them. Another thing that’s often
over looked is the tires and when you’re checking the tires you want to jack the wheel off the
ground and you want to look it all over for thorn holes you want to look for any nails
or things. On tubeless tires, commonly something can go in the tire and if it stays in the
tire it’ll stay up, that’s one of the advantages of tubeless tires. The other thing is air
pressure. Air pressure on a locked rear end vehicle is very, very important. People commonly
say my vehicle pulls, my unit pulls to the right or pulls to the left when I drive it
and I don’t know what’s wrong. Well, on a vehicle that doesn’t have a differential in
the back or say when this one is in 2×4 vs. turf mode, the problem is, if the tires aren’t
exactly the right, same circumference, which usually is a function of tire pressure, then
the larger tire is gonna be the more forceful tire and it’s gonna try to make it veer. Say
the left tire is slightly larger in diameter due to having more pressure in it it’s gonna
make it pull to the right. If the left tire is larger in diameter, it’s gonna make it
pull to the left. Sometimes if both tires have the exact pressure on these kind of tires
they won’t be exactly the same diameter and in the past the only true way to know is to
run a tape measure around the outside. If a person is not having a problem with it,
they both have nine pounds in it, it drives OK, you’re not really having an issue then
ordinarily it wouldn’t be a deal. But if you are having problems like that and you suspect
that that could be the issue then the only way to really tell is put a tape measure around
the entire outside of the wheel and compare both wheels together because sometimes these
tires will, one will swell up a little more than the other. Also, the other thing with
alignment is checking the front end. On a Polaris when the handlebars are sitting straight,
most Polaris’ front end, the handlebars would be, the front wheels would be towed out a
half an inch which is 1/4 of an inch each way from straight. The camber and the caster
on the front end isn’t adjustable, if it changes it’s usually because somethings bent. But,
the tie rod adjustments or wear or a wheel being bent or something like that those are
all things you have to look for. These are utility vehicles, they’re not a Lexus car,
okay, they don’t go down the road, they don’t go down the road perfectly, they’re a utility
vehicle, but they still, they should drive good and they shouldn’t have problems and
you should be able to take your hand off the bar and it shouldn’t shoot of the side of
the road. So, those are all, those are all things that have to be looked at. Different
units have different tire pressures. Rangers, 9 to 12 pounds say, a unit like this might
be 6 to 8 pounds, it just depends on the unit. Smaller units usually take less tire pressure,
bigger. Heavier units usually have more tire pressure.

  1. @sasktank we put mud lights on the rear one one of are atv's it just a recon 250. so we just did rear. and it says 7 i think maybe 8.

  2. sir i need an advise, im a newbie, i got a 2nd hand BMX 150cc atv with front and rear tire pressure indicates 70kp3(10psi), i know it is different from bicycle psi. does it mean car tire pressure at 10 psi only????
