TM155 Tyre Pressures

[Tonyh7740]

I have a TM155 on 650s and 540s on solid rims, with a 500kg front weight block. I’ll be pulling a 14 tonne trailer on the road and field, that’s it, no mounted implements at all. What tyre pressures would be best for me? And for comfort without endangering the tyres. Thanks.

Now Then..
Look in the tyre manufacturers data book if it's available, weigh all axles when loaded, then cross reference with your travel speed for the answer.........

Leave the weight off

Leave the weight off

The suspension seems to work some bit better with the weight on

If tyres are right pressure it should be ok not much point bouncing a weight about wearing tyres off

Hence why I’m asking what is the right pressure?

 

[ridger]

I have 14 in front of 3 of my tms and 35 in the one with the loader on so that I can steer it

If it works without the weight, leave it at home. It'll cost you more in fuel. Obviously you'll see the suspension working more with 500Kg on there as there's half a tonne to support!!

20 all round here for road work

That’s the problem, you don’t see it working . New Holland front suspension is a whole can of worms!

yeah no worries

John Deere operators do the same. Put the weight on to see it move!! A trailer should only impose 3000Kg on the hook. Is front ballast really needed for that??

Try and find a trailer that only has 3 ton on the hook when loaded though.

I have a weight but it hasn't been on for 5 years, don't see the point, sticks far too far out in front apart from anything else

I go 28 on rears might bounce but knackers the tyres running too soft! I always find trailers load the arse end more than you think!
