Hi,
I picked up my new swanky new shape range rover this week, and i bought a set of brand new original overfinch 22" alloy wheels and tyres.

The problem is that they have come with 285/35/22 toyo tyres on, now I've noticed that the tyres fitted from the factory if you go for 22" wheels are 275/40/22 contisports. I declined this option as I new I wanted the overfinch wheels.

I have spoken to the company who supplied the wheels and they have said these tyres are fine and will be ok on my car.

So, in short does anyone know if what there telling me is correct, I told them what car they were going on prior to buying them by the way.

Hopefully I'm worrying over nothing but if not I'd rather get the correct tyres fitted and then argue later.

I hope all that makes sense, and thankyou in advance for any advice.

Ant.

P.s. i didn't get them direct from overfinch it was from a company that I assumed was a dealer of theres.

not being funny but you did not check out if the company was an 'approved' overfinch dealer? - if they are not what about warranty?

the toyo's are a cheaper tyre - if i was in your position i'd go for the Conti Sport Contact 5 in 275/40/22 as factory spec to also avoid any possible warranty issues on the car as a whole

22-inch wheels on a 2-tonne SUV - good luck! potholes will destroy them - the factory upgrades are about 3 times the rigidity of any aftermarket ones - hence the extra weight of them.

You will, like my friend Bob, get pissed off with repairing them and go back to the factory 20-inch items.

bear in mind the OP has the new L405 which has factory option of 22" wheels so don't foresee a problem - Overfinch wheels should certainly be up to factory spec

and as a 'standard' size the 22's don't need to run on skinny 'rubber band' tyres!

don't forget that the L322 had a max of 20" wheels as a factory option?

People fuss waaaay too much over tyre sizes tbh. If they fit - what exactly is the problem apart from the sense of taste?

OP is rightly concerned as its a brand new car - warranty issues?

How can a very similar sized tyre cause a warranty issue?

firstly, the OP quoted wheels/tyres non dealer supplied - ditto profile

would you buy a £100K car and piss about?

probably!

If you have a warranty issue why not swap the original wheels back on if you are so worried about it.

And evidently the op is happy to piss about with it - they bought some aftermarket wheels in the first place.

jesus - you could start a fight in an empty room! - i've read your profile - get over yourself please?

the OP is going back to manufacturer recommended tyres - as i suggested

other issues are Overfinch related - something i don't know about!

I would take a stab at tyre load ratings being an issue with some tyres.

I know on the D3 forum, that some people have bought 22s and the tyres are below what's safely needed for use on the D3. Not very likely, but some were questioning wither insurance would overly impressed if you had a bump and the sub rated tyres were a factor.

OP, any pictures of said new RR with the alloys?

Definitely an issue with the D3/4 as it is significantly heavier than the L405.

Bear in mind that if you fit a sport tyre, you'll have a lot more grip than the CrossContact LXs which are the standard fit, so you'll probably find you get the ocassional odd intervension from the DSC as you can achieve higher lateral acceleration.

The LX is an excellent tyre however, especially in 22in size.

Differ sidewall profile here may effect loads seen on suspension parts.

Some of the points on here are good advice. Try going back to the standard size 275/40 tyre which would have been engineered for the car. In addition, a 275/40 will give you better impact protection for your rims than the 285/35 by some margin.
Probably best not to fit sports compound tyres to a 405 as it likely hasn't been configured for them so as Racer Mike says, expect DSC intervention and other joys of chassis engineering to intervene.

your fine with the 'sports' compound tyres on L322/L405 Range Rovers - these tyres have been specifically designed for high performance 4x4's like RR/Cayenne etc

But not as an OE fit to 405 or 322. All the current 405 tyres are all seasons, and all the Roll Stability Control and DSC is tuned on them. When you greatly increase the lateral grip available, particularly on an SUV, it will cause a lot of false intervensions and will also mean that the Roll Stability Control is massively compromised. Things like the active anti roll bars are also calibrated to all seasons, so that in itself, if you've specced it, will be out of kilter due to higher lat acc.

There really isn't a great deal of point IMO fitting a summer to the 405. The Cross Contact LX is a really great tyre and is hugely capable in all conditions. No, it won't get you the fastest lap around the 'Ring, but it's plenty good enough and means the car works as originally intended.
