Comparison of Tyre selection for 19" and 20" rim

Babs,

I think you might misunderstand what I am saying, I don't "pussyfoot" at all.

If I felt the tire size was restricting where I could drive I would have swapped to 18' some time ago. That's not the case at all.

We've all seen a group of people climb a steep loose hill:

Some get there with a big right foot and blast there way up with lots of momentum (and a certain amount of luck)

Others will get up the hill by taking the correct line, selecting the correct gear and avoiding loss of traction. Ultimately getting anywhere the other guy can get, with far less stress on the vehicle.

In my view, if you drive more like the second guy.... 19's generally will not hold you back at all. 20's I suspect would be the same, but I don't have thousands of kilometres of experience to back that view, which I do with the 19's.

You just need to understand where your wheels are - which will help make you a better driver anyway.;)

Maybe I've just been lucky. ;)

Work out what you primarily drive and choose accordingly [emoji56]

I don't have the specs..

Keep in mind Ply rating - not Plys is the modern standard.

In the case of the 2 tyres mentioned both are XL not LT...

And carcass and sidewall strength also depends on design, rubber compound, thickness of rubber (not reinforcing cords)...

Put in context -

Babs has damaged 19s almost immediately and every time he went out. His solution smaller rims and then oversize tyres..

Bytemark damaged a Hankook 19" tyre through "less than thorough offroad planning" (didn't drop pressure) but then went on to do thousands of kms without issue on gibber rock, sand, mud, stone etc..

Basil135 has done gibber, sand and dirt on 19" Duratracs without a hiccup.

It does depend on how you drive, where you drive....

I've seen guys with vehicles running 16s (not D4s) that are like magnets for punctures!

The other variable, could be towing..??

Babs, not sure if you are towing, but I'm not, so particularly the rears don't have that additional down force... ( Except all my crap in the back :angel: )

Yeah we got through about 800 kms of Flinders Ranges offroad on 20" Cooper LTZs with no punctures. Quite a few chunks out of the side walls though.
Meccles has just put Nitto Terra Grappler 265/50/20s on his RRS and is happy so far. Just another option ...

Good afternoon gentlemen, today I bid farewell to my beloved 2012 L322 - yes, sad face. The car is perfect, best I've ever owned, but practicality in our future of long distance off-road touring dictates something more of a workhorse.
NOTE: During the deliberations over a replacement for my FFRR, I agonised for weeks...even to the point of ALMOST thinking about possibly considering going over to the dark side. You will be pleased to know that I resisted the temptation of the siren call.
So I'm awaiting delivery of my 2016 D4 from Sydney in a couple of weeks, and in the meantime, scouring the forum for as much education and wisdom as I can find re the D4.
Among a long list of build items, are tyres. It comes with standard 19s. I considered getting the GOE 18s, but in an attempt to keep costs down as much as possible, I'm going to see what I can do with the 19s, at least for the next 7,000km trip this year, through the Kimberley and back down to Perth via the GCR.
With that in mind, I spied this offer on eBay yesterday:
LAND ROVER DISCOVERY 19" Wheels fitted With COOPER ZEON LTZ tyres (SET of 5!) | eBay

Would appreciate input. Good deal? Good idea? Bad idea?
Or, just use the existing rims and put better tyres on them...

You know my thoughts on this and if you look at all my previous comments on rim sizes I was adamant I was going to stay with the 19". I did the biggest backflip and can't recommend going to an 18" enough.

Congratulations on the new buy and good luck whichever way you end up going.

I'll most likely be doing the Sandy Blight Jn Road, Gary Jn Road & Gary Hwy mid this year on 19" Hankooks. I don't think the sky is going to fall in....

Carry a new carcass (no wheel) if mildly concerned - will speed up replacement if necessary at a remote site.
