Is there any combination of rim size, tyre etc that's most resistant to pothole damage? Road conditions around here are shocking.

Trying to think ahead of RR purchase.

Your best bet to avoid pothole damage would be 18" rims. Due to the thicker side wall on the tyres. The thinner the side wall more damage to be expected.

I agree.

Or drive slower and have bigger rims. Your choice. Si. <This is my name.

I eat rat poison.

A man ain't truly been insulted until he stands buck naked in front of a woman and she didn't even notice. Or care.

Genuine wheels fair better than after market wheels. Take a look at the Range Rovers on wreckerexotics.com and notice that the after market wheels fall to bits in an accident.

Well, I swapped the original 18 inch wheels on mine for 19 inch original Vogue ones.

Thats the ideal compromise to my mind.

Yes, 18's are the best for potholes, but don't fill the wheel arches enough for me.......

But the tyre outer circumference is (should be !) the same so how does it fill the wheel arch better ? .

Thanks for the advice, all.

Driving slower isn't really practical in that these holes open up very quickly on all kinds of stretches. I've ruined three tyres this year, none at speed, and swore to myself I'd never use alloys again. But RRs are alloys as standard, aren't they?

18s it will be if I have a choice.

I clonked a pothole with a lovely thud but it didn't do any damage to a 20" SC wheel/tyre, I did need my tracking doing later though. I'd go for what you think is cool, but definitely go OEM and no bigger than 20".

As soon as I typed "fill the arches better" I knew someone would pick me up on it........

Should have worded it better - the 18 inch wheels look just a bit too small on the car........

I have a mate who has built up a good going business refurbishing alloy wheels & he claims that if it hadn't been for Range Rovers especially the Overfinch models then his business wouldn't have survived, as it it the business is going really well. The Local Land Rover dealership are his best customers. One thing to note is that he never comes across 18" alloys unless they just need a refurb for flaking laquer.
So I'm sticking with my 18" wheels, besides which my wife has a horse trailer & 22 alloys would be a joke in a field, whats the point of running one of the best 4x4s on the planet if you cannot utilise the ability of the car?
But then I'm an old stick in the mud (if you pardon the pun) who cannot understand why an ordinary model of car gets the roof lopped in half & losses two doors to become a "coupe" & still attracts buyers, what the hell is the point?
That should set the cat amonst the pigeons...Robert.

If I could run 18's I'd probably have a set for camping / mild off-roading, but I don't think some models can run them. I'm not sure you can fit less than 20's on a SC?

On the flipside, I was running on road tyres on 20" rims when we had two feet of snow and ice everywhere. Didn't seem to make a blind bit of difference - just drove through everything .

The standard 20's are fine for mild off-roading, it would be a complete waste of time and effort changing your wheels to drive onto a camping field.

Try and blag a 1/2 day with Land Rover Experience, and you will see just how capable a Range Rover wearing 20's is off road.

It's the 40-50mph into a 9" deep pot that's been costing me rims and tyres. It's become a very serious winter issue, and with the economy here the way it is councils are only going to get poorer and less able to fix roads that were often badly surfaced in the first place.
