Maybe I'm wrong, but I thought 225's where also a standard fit. The RRC was in production for quite a long time.

As for steering, well "adjusting" the steering stops is hardly a modification. And running either wheel spacers or different off set rims would be possible without body or suspension mods, so long as the tyre wasn't too tall.

Nope, 205/80/16 was the only standard fitment from the Factory on RRC's (Overfinch and other Specials aside), although the 225/75 is a very similar rolling radius, as is the 235/70 that I have.

Yes you can go wider than 235, but not without making adjustment - and IMO, unless you're getting serious, there's no need either!

Think ours had 225's on them. Guess they must have been changed.

Suspect you should be able to get a 255 or 245 on though, you just need to drop down the profile height. And this would be more road use than off road.

Sure. Where abouts are you in the country?

Water over seat level (fully submersed engine bay), mud over tyre height, vertical drops into mud / water pools resulting in landy getting stuck on its bumper at the bottom of the mud (how it didnt sumersault we'll never know) rock crawls which killed 3 out of the 6 landy's in the group (1 tyre popped off, 1 engine blown and 1 rear dif or half shaft issue) and landy on its side from a slight mis judgement of severity of the angle of something!

the 2.25 petrol engine did eventually die on a P&P site though which forced the 200tdi conversion.

But, yes, i agree, there are design flaws with the series which have been addressed in later models (i.e. defenders) I still stand by what it costs for me to keep and run a series in comparision to a defender it's still the best choice for me. One day i'll hopefully replace it with a bowler wild-cat type machine, but, until then, i'm happy in my Series :)

Sounds fun.
 
hows about this idea tall n thin tyres at the front (not pram wheels ) something like standard series tyres and slightly wider tyres at the rear something like general grabbers

if that idea has worked since the dawn of motorised tratters and not needed changeing it makes sense to me to do it with offroaders

my thinking being the thin tyre will cut the **** /snow creating more surface area for the larger rear tyres to grip

or am i barking up the wrong tree ( wonder why its silver with a light on top)

That wouldn't really work! It would put a lot of strain on the rear diff and viscous coupling, hwere fitted.

Tractors also have a much larger diameter rear wheels - this is because those tractors are RWD only, and all the weight of the trailer/plough/machinery forces the larger wheels into the ground to provide traction. The thinner front wheels are not driven and only used to steer, so larger wheels would just make them harder to steer and cut through the mud - this was before the days of power steering. The smaller/thinenr tyres provided lighter steering and a smaller turning circle.

If you look at any modern 4wd tractor their wheels are the same size now, or very similar, and often the same width too. These tend to be hinged in the middle of the tractor unit to enable tighter steering/turning circles, rather than turning the front wheels like a car. So they have 4wd, big chunky tyres AND a good turning circle - perfect!

nope.if wider taller tires are better theyd come wiv em.do you employ hundreds of people day in day out to design and build cars?no, but LR do.so lets assume they know wot there doing.

Totally agree, I've always stuck with the standard 235-85-16's no matter the make or tread pattern..;);)
 
the factory fitted tyres are a compramise aimed at the average buyer , designed to give adequate on road performance .for mr or mrs average, they are not the optimum for any one set of conditions..and dont forget the bean counters will also have had an input .
having said that im happy with my 205 x 16s.... most of the time im pottering round on tarmac, rarely exceed 60mph and dont get any insurmountable problems with my usual off tarmac driving....
i accept . theres tracks down on the peat moors that i wouldnt try driving down today but might be passable with different tyres....but theym prettier in the warmer/dryer weather when the flowers and insects is out anyway.
 
My 35s performed really well at buildwas last weekend, some of the ruts were really deep and trucks with 31-33 inch tyres were grounding out and getting stuck whereas I could trundle along them quite happily. They also climb and bounce over obstacles a lot easier than smaller tyres.

So tall tyres are definitely worth having...

Wider tyres perform much better on deep, soft surfaces and avoid sinking and bogging, such as on deep sand or snow or mud.
