Thread: 19" Maxxis AT Tyres

Maxxis update, had them off road again this weekend, same tracks as the last update when I had the two sidewall stakes.

I took the advice from here and lowered the pressure I ran back at 25psi and front at 23psi traction was definitely increased and I pushed them over rougher terrain than last time when I had pressure up.

At a brief inspection there appears to be no damage but I still have to give them a clean and do a more thorough inspection.

So at a glance the lower pressure is more productive contrary to the mixed info on keeping higher pressures to protect the rims and tyres

[QUOTE=Babs;2604468]I understand your feelings towards the gripe of 19" rims but it's not as easy as what you say in regards to other modifications.

With other modifications there is a broader choice of accessories, however the 19" rim really is a thorn in the side of a Discovery. If there were higher profile LT tyre choices then this would never be a concern and you wouldn't read a mention of it. Unfortunately going to an 18" rim is extremely expensive for some and you don't get a choice to what is available.

So I understand and side with the gripe of the poor decision/design of Land Rover going with a 19" rim. It's appalling!
Me personally I'm happy to read other members gripes on this topic.


I have to agree with you totally Babs. for a vehicle with this 4WD capability, 'LR" should provide wheel options, and not just left to only one aftermarket expensive wheel option ( Compomotives - which I did reluctantly go to the expense of purchasing) . LR pride themselves on there history of making 4WD capable vehicles - so why stop now by not providing an affordable wheel option when you purchase the vehicle new. Just my opinion too ...

Regardless, as I mentioned earlier, the LC200 struggles to stop at the best of times compared to a D4..

And the other factor is repeated applications... a D4 can e-stop several times with minimal/no brake fade!!

Is that the 2.7 or the 3.0l?

The Merc G wagon has 19 inch rims stock, come from the showroom floor with Pirelli scorpion zeros
275/55/19's on the driver said great tyres however they seem to be a tyre for colder climate and snow with a max psi of 44... also 255/60/19 there are a few tyres but similarly seem to be for colder climates...

Website shows 265/60 18s for the 350d with 20 and 21 on AMG versions?

I didnt grab the variant details.. but I did take a shot..

That's not a Scorpion... Now THAT'S a Scorpion

Fact remains that the sidewall is a lot lower to the ground on an aired down 19 running 255/55 than on a 245/75 on 16's. We were running 25 pound. On a 16 suitably aired down the bulge is less severe and has a more gentle curve up and out from the tread... So less prone to damage. Anyway my mate knew if would be a close run thing in Sundown with those tyres and it was. He will now move to the 980 in LT. Cheers

I took my newly acquired D4 SE MY13 into Sundown on the 29th of Oct as this is where I seem to gravitate to with any 'new' 4wd to see how they rank. As time didn't permit a full day of play I just took the Back creek track from the ruins around to Red Rock Gorge then back out the normal track. This back track would have to have some of the hardest rocky track conditions I've played in. The car has Cooper Zeons which seem quite good to me (so far) as they grip on black top and gravel, wet or dry, and very importantly after living with BFG's for the last few years are absolutely quiet.

I'm quite concerned with the 19" and low profile tyres and have over the last few hours read this entire thread. At the end of it I really am none the wiser, except I see that I'm not alone in wondering why LR has chosen this path.

One question based on an observation from last weekend regarding pressuring down the tyres for that rocky type of surface. As we towed our ~2.5T caravan to Girraween for the weekend, my tyre pressures were 36F38R and I didn't drop them in Sundown. One of the spots that I got out of the car to look at the obstacle in front I noted that the front right tyre was half on a rock of around 200mm in size. With the vehicle's weight being supported on approximately 1/3rd of the normal contact patch the sidewall was was rather compressed and made the tyre look flat. That's with 36psi, had the tyre pressure been lower then the only thing between the rock and rim would have been the rubber.

Do we really feel that it's a good idea to drop the pressures on these low profile tyres? This experience suggests not to me, but I don't profess to be an expert. Coming from 16" wheels (Pajero, BFG AT) which had a comparatively huge sidewall I'm struggling with the risk of rim damage due to under inflation on such obstacles...

Also I see that we don't really like the Zeon's, can I please get some feed back on what the issue is with them? The original owner of my D4 swapped out the OEM tyres when new and the car is on it's second set of Zeon's, and he has done the same with his new vehicle, so he obviously likes them...

So far (only done 3000km) I've been running them at 36f36r for normal road work and experimented with 38r last weekend with approx 100kg in the boot family of 4, caravan ball weight ~250kg, ARB Summit bullbar and winch up front.
