Quad Tyre Pressures

[Jerry]

Just swapped rear tyres on the quad as the old tyres were more like racing slick tyres than anything with a tread and were getting dangerous going down grass slopes first thing with a dew on the grass.

Opted for some BKT W207 to match those I put on the front back in the spring.

Tyre place have put 20psi in them saying thats what they need but the ride is very hard and I feel like Im slewing around at times.

Got a feeling 20 psi is just too hard??

Sure I ran the old ones at about 10?

Honda 425s sticker states 3.5 psi, standard airline gauge will not be accurate enough and you will need a small hand held pressure gauge to set them the same

 

[Timbo]

Around 10-12psi be better if you are doing any road work, 6-8 if not.

 

[Jerry]

Thought as much, have a digital pressure gauge that came with the bike.

Tyre fitter is being a numpty!

I seem to recall that Honda used to recommend 2.5-3.5 psi but think they say 4 now. On hilly ground tires any harder than that are worse than useless.

I run kenda bearclaws on my Honda 420. Backs at 4psi and fronts at 4.5.

Iirc tyre fitters recommend running the tyres pretty hard for the first couple of days to force them to run true because they can be out of shape while in storage/delivery

About as low as you can get but don’t get too razzy as they’ll hunker down and throw you off. The w207 have side lugs that need a low pressure to be any good, can’t stand seeing the middle of the rubber being worn because of too much pressure.

 

[ROBINWORKS]

Tyre pressure usually written on a warning sign on the atv, usually around 4.5 for rear and 5 for front, depending on the make, usually a pressure gauge in the tool kit.

As soft as possible so the side lugs are actually doing something..

See plenty quads with the middle of the tyres worn to nothing and the outsides looking like new

 

[J428TGS]

2-3psi just enough to keep them on the rim..... well nearly

 

[Macsky]

Hard tyres are also hard on every other component on the bike, tyres running proper psi take a lot of the shock out of the terrain, bearing/bushes etc will last a lot longer, your spine too!

Be careful with W207’s, they grip like hell and can easily roll if turning at speed where your used to back end going out as the backend doesn’t go out it goes up!
