Have you done Fraser on 19s?

[catch-22]

We had to get the SD4 HSE, didn't we...:D

19 inch wheels. And we're considering taking it to Fraser and staying in one of their resorts there for a few days.

Keen to hear if anyone has taken their FL2 with 19s. I know they'll do all that others can do - but the low profile tyres concerns me.

I had 18s on mine and found them a little better than the 17s on sand as you keep a bit of clearance with the larger wheels.

Depends on whether it's rained or not. If it's dry and you can't lower tyre pressures to around 20-25psi or so then you will probably struggle, if it has rained in the last week or so then it probably won't be a problem. I've seen heaps of Touaregs & BMW's around the island doing OK when its rained enough to get the tracks damp.

18's have an inch less rubber than 17's so no extra clearance I'm afraid.

Caine, why don't we have an FL2 day up at Stockton as a test before you go? If you can do the stretch of beach between Lavis Lane and the wreck then you can easily handle Fraser. I've been to Fraser a couple of times and that stretch of Stockton is worse than almost everything up there. I'm happy to come with you in mine and pull your 19" mall crawler out if it gets stuck... :p :D

We had a Evoque at Stockton for Range Rover Club driver training.

It was fine on soft dry sand as they have a good power weight ratio. In fact it climbed out of a bowl better than d3-4s.

The car got bogged where some tracks converged, and there were deep ruts, as the Evoque and I assume the F2 have quite a low front crossmember and it bellied out.

So problems may arise on track entries or around rock outcrops where tracks converge. I don't think it bellied on "normal" depth tracks along the dry sand, just where the tracks had to converge and they were deeper than usual.
Getting off the barge comes to mind, but there are always lots of pushers around there anyway.

The other things to note are that the road oriented tyres did not want to climb on to my Maxtrax due to lack of tread, so we had to dig them right underneath, and I am trying to remember whether it had a good recovery point, and I think not.

Should still be same rolling diameter however my theory is that even with a flat tyre you will still have more clearance with the bigger wheel size and lower profile tyre (within reason). the lower rim size the higher the side wall ratio you need. as long as the tyre elongates when deflated you should be fine don't worry too much about bagging on the side. some tyres when you start getting up there can be so stiff on the side wall you may as well be driving at 40psi

Why how gentlemanly of you, Mike.....

I'll be in touch

[mikehzz]

I'm pretty confident neither of us would get stuck but you never know on the chopped up stuff so its better with 2. Shock horror...you might get to pull me out. :)

[catch-22]

As long as no one takes photos, we'd be the only ones to ever know it happened......if it did.......which it won't....

[Vesko]

Give me a buzz, I might join you if you don't mind :)

[mikehzz]

It must be a few years since your last trip?

[mikehzz]

Hey Vesko, Caine said no photos... :)

[Meken]

I've found it's all about the tyre pressures. We have 18s on our hse and 1st time with about 20+ psi I got well & truly bogged to the belly in the soft beach exit on north straddie (converging deep ruts) last time I was down near 12 & it was like a hovercraft - floated over all the really chopped up soft stuff like a dream - you just have to be a lot more careful to drive smoothly at those pressures to avoid accidentally rolling the tyre off rim (but I hear the LR rims have a good bead lock) - oh we are on conti cross contact uhp (basically road tyres) I would even go as far to say that I could have stopped in the soft stuff & get going again without issue.

Hi mikhzz
Be kind enough to explain why 18inches is an inch less than 17.
Or am I missing something

I said you have an inch less rubber mainly because you have an inch more rim.
The outside diameter of the tyre is the same for all fl2's. If the rim is 18" then the height of the sidewall will be 1/2" shorter on the tyre than it is for a car with 17" rims. 1/2" at the top and 1/2" at the bottom means you have an inch less rubber. On 19" rims you have 2" less rubber sidewall than a 17" rim car. The standard sizes for fl2 are 235/65/17, 235/60/18 and 235/55/19 They all have roughly the same rolling diameter.

Hi mikehzz
I have just looked at 'tyre conversion calculator' on google and it tells me that 235/60/18 are 739.2mm dia. and 235/60/19 are 764.6mm dia.Thats over an inch bigger in my book??

[mikehzz]

The 19's are 235/55/19

[mikehzz]

All the rolling diameters are within a few millimetres of each other so the speedo and trip computer are consistent no matter what rims are put on.

Okay, I know its been a long time "between drinks", but with 19 inches? No thanks!

Just let the air out (not all of it) they are a relatively light car with good power to weight ratio
