Optimum Comfort/Handling Puma 110 Tyre Pressures?
I’ve recently taken possession of my Defender 110 Commercial and I think the tyres are maybe over inflated. It’s ride seems a tad harder than the identical 110 Station Wagon I had before.
Before I just head down to the Petrol Station to check or adjust to the recommended 28PSI front and 35PSI rears, I was wondering if long term owners have come up with their idea of perfect tyre pressures for them that provides maximum comfort/ride without affecting handling/safety or tyre life adversely?

What models have 28/38 recommended tyre pressures? My 07 110 Puma SW say 30 Front and something 48 rear for light load use. The ride is like concrete at that, why does my model have such high recommended pressures? 2007 110 TDCi Station Wagon XS

I have one of these stickers attached to the drivers inside door. Though 65psi for rear towing I have never gone for.

Not sure where those figures originate but they don't match my handbook or Gilarion's sticker. 2007 110 TDCi Station Wagon XS

32 psi all round for me. 20-ish if it's getting proper muddy.

Mine has a cage fitted so has another 150Kg or so. Feels about right and tyres don't overheat - 7.50 XZLs.

I stay with what the sticker says. 45 rears normally then 65 when towing this beast of a trailer.

MTRs are wearing perfectly evenly at nearly 40k on them

I run my 110 SW summer tyres at the official owners handbook pressures. However currently have my Hakkapiettas fitted. Nokian’s recommendations are different:-

In round figures this works out to be:-

Light load - F36 R38
Heavier load - F36 R41

Hi,
I did have some one ten in the past.
Then the rr from 1992 to 2012.
When I did have the Defender 110 sw model 2012, I was horified with the lack of comfort.

I have try other tires, no change.
Then somebody did tell me that the damper are different today for security ....

I have change the damper with old model, could be not a good idea, but it is more comfortable.

I have two similar sticker, one stuck in the handbook the other loose . The only time I use the higher pressure is when towing the caravan and when it comes out from M.O.T. and services as the garage insist on put the rears up to 65psi. The one's quoted by the O.P. seem dangerous and could lead to prosecution if checked by either police of VOSA. Don't make old people mad.
We don't like being old in the first place,
so it doesn't take much to Censored us off.

My 110 double cab is on 255/85 KM2s, has a Husky on the front, and routinely runs at around 2750kg. I run the fronts at 38psi and rears at 48psi on the road, and have found that this produces perfectly even wear across the tread.

A 110 commercial (ie HT or DC) will always have a harsher ride than an SW due to the different springing and vehicle weights. The OP could always put a couple of paving slabs in the back!

Just spoken to my dealer I bought it off who has said the suspension set up is the same for the Station Wagon or the standard commercial which mine is. So I’m just going to let the tyres down a wee bit to maybe 26 front and 32 rears. See if that improves it a bit. It’s not a major issue but I do have quite a few bumpy roads near me

Smiles,
whilst your proposed reduced tyre pressures may make the ride feel softer, you are actually compromising tyre integrity by running them under inflated. There’s obviously a cost involved but the better way to soften the harshness, is a “tuned” spring/shock set-up.
