Thread: 2013 honda trx500fm tyre pressures

Has any of you guys got the same bike and know what best tyre pressures to run are? I’ve looked online and getting mixed answers… Cheers

Max is 6 psi from memory check in tool kit they come with a low pressure gage , reads about 8 psi max 4 psi is a nice setting but depends on surface important that fronts or / rear all the same for safe handling

I run 5 PSI in my 420 but even then my tyres are 6 ply and quite stiff in the sidewall so they still don’t flex very much at that. I think anywhere in the 4 - 8 PSI range is probably normal depending on the tyre

Old manual says 3.8psi rears and 4.5psi fronts. Your finger push test will tell your brain that's too low, but my tyres are almost completely worn out, and the remaining bar treads are exactly the same height across the entire width of the tyre.

My 2005 TRX500 is 3.6psi +/- 0.4 F&R on the label. I run it at 4psi all round. I invested in a proper low pressure dial gauge to do mine & keep it, plus repair kit and a small compressor in the box under rear deck.

I set mine on 12psi (450), maybe a bit too much after reading the comments above me but never had any trouble with it.

Factory setting is around 4psi. At 100 hour service we generally set pressure at 6psi, have found that owners generally don't check pressure between services and they usually loose a bit of pressure over time. Most are 4 ply tyres. Our biggest sellers are Maxi Grip SG-789 series and everyone seems happy with ride and wear at 6psi.

@woods223 maxi grip ultra's For me i drop my pressure during mid winter. Also depending on loads.
Also use a kingchrome digital gauge from bunnings

Yeah 4psi as most have said, the important thing is to check them regularly a difference in psi makes quads shitty to ride especially in the front.

That's because we let them down as soon as the service truck leaves

That’s good for the owners that actually check things but a fair number don’t check anything from service to service. Paint dots undisturbed on dip-stick etc and comments like “are we meant to check the oil, thought that’s what the service was for.” Fark!

You loose the oxygen from your tyres leaks faster than nitrogen that's why they go down in pressure.
Settles down after a period of time as you slowly loose less oxygen.
You notice it on road bikes especially.

or they go completely overboard - actually read operators manual and then become instant service mechanics -used to service tractors many years ago - client decided his Iseki clutch needed adjusting - then Iseki would not start -had set the pedal actually correctly but forgot to adjust the safety cut out for starting tractor - drove about 50 kms for 5 minute fix

Neighbour bought a service station a few years ago.

Client brought a quad wheel with a puncture to be fixed - no problem says neighbour - does the fix and inflates, next minutes there is a god almighty bang as the tyre explodes.

Rings me up to see what pressure he should put in in it - I told him about 4 lb - he had put in around 40 lb.

Im using them on my hunting quad with good results, gotten 6000km from them with 40% wear but will replace pretty soon
