Wheels

I'm not sure that increasing the wheel width will allow the tyre to balloon. It will push the sidewalls out at the rim, making them closer to perpendicular with the treads. That would give a firmer ride and perhaps less sideways movement whilst cornering, but I'm not sure it would give more ballooning when aired-down.

Also note that most 7.5 R16's have a recommended rim width of 6.0", 5.5-6.5 acceptable, and would almost certainly be out of spec on a 7" rim (though I don't know the spec for your particular tyres).

I tried in 1st 4H and then even in 2nd 4L and couldn't crest it, IF I had more surface area I my tyres would I make it??

I think the lack of run-up would be the main problem. I have used low 2 on numerous occasions on sand and it worked well. Did you try low 3 with a longer run-up?

Thanks for any comments

Defender 110 steel rims are 5.5" ie same width as series rims. Alloys are 7". 130 rims however are 6.5"

It was a really awkward setup there was a sharp left turn which wiped off speed then there was a small hill which wiped off more and then the big hill which I couldn't get up. I think I'll have to get done pics of it.

Thanks. I wasn't sure of the defender sizes so I thought if I just guessed someone with the correct knowledge would help me out :)

Sounds like the exit at Binningup beach.

My Disco stopped in the deep loose stuff in low 2 with myself contemplating and undignified reverse down a nasty ramp, with a roll-over type drop onto the beach :eek:

Mercifully it started off in low 1 and got out :D

Hello from Brisbane.

I guess I am about as confused as poor old Grey Ghost should be by now.

I was of the understanding that the various wheels were of the dimensions listed in the earlier post by Numpty. However, I also thought - wrongly perhaps - that the 130 wheels had ventilated centres.

The post even earlier from Dauntless has a photo of what appear to be 16 X 6.5" rims - apparently from a Defender. There are no ventilation holes in those rims that I can see. So, is it possible to get non-ventilated 6.5" rims here without seeking out a set from a forward control which is the popular route in the UK for putting wider rubber on restored Series without compromising the original look too much?

Cheers,

The spare for my 130 doesn't have the holes, but the rest do. If I remember right, the early 130s didn't have the holes...

Saw these today - might be an option for wideys on a series:

ROAM OFFROAD

I'm sure you could get that done out here.

I'm quite sure they're standard Defender rims, they even have "Made in England" stamped in them. I got mine in Sydney from a guy who was running them on his Disco I think, or at least intended to.

6.5" width, 20.6mm offset.
They be early pre '97 i think 130 rims.
Before the ventilated look, often referred to as "WOLF" wheels.
