Whilst pumping up one of the front tyres on my 2010 TDV8 HSE I checked the recommended pressure on the front door sticker and it said that the tyre size should be 275 40 20. I’m running 255 40 20, which using an online tyre calculator shows approx 3/4” smaller rolling radius than the 275.

The tyres seem to sit perfectly on the rims - I think widening them out to 275 they’d look too fat.

So the question is, am I on the correct wheels for the car ? I do think they are the best looking RRS rim out there.

Currently sitting in off road height setting in the pic if they look a tad small.

Looks like a L322 Range Rover wheel, not an L320 RRS. If so it’s probably 20x8.5 with a 57mm offset. Stock wheels on the L320 RRS should be 20x9.5 with a 53mm offset. If you want to get closer to the correct diameter you should look for 255/45R20 tires. The average recommended max tire width on an 8.5” wide wheel is 255 so you’re rather limited by this. 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

They are L322 Westminster wheels

RRS had 275/40R20 from the factory, but a lot of people fit 275/45R20 as there is a greater range of tyres to choose from

The equivalent size of 275/45 is a 255/50, but they look a bit "balloony" on a Sport...

I have no idea if a 275 wide tyre on an 8.5" rim would cause issues, but its only 10mm extra on either side of the wheel...

Thanks both - really helpful. Now I have to decide if I want to stick with them, or go original…

I do really like the look and the tyres all have really good tread.

Explains why the Brembos don’t fit with them as well !

Following on from this - I can get some mint style 520 (10 spoke V) wheels locally for a decent price. I think they were standard on an L494 ?

Hopefully the offset should allow Brembos and. 275 40 20s ?

If anyone has pics of an L320 with these wheels that would be much appreciated.

Cheers

I think you may find the 520 style rim is still a 8.5J rim, but happy to stand to be corrected.

520 style is 20x8.5 with an ET47 offset.

If I’m remembering correctly they will sit inward by 6mm compared to the stock 20x9.5 ET53 wheels. 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

So that pretty much rules out using 520 10 spoke style with the Brembos as the offset is too “in” to the hub ?

Probably worth just checking with your insurance company that they are happy with a) spacers, and b) wheels that were never specified for the L320 (albeit they are gen LR and no doubt have the correct weight loading).
I like them btw.

Good points - thanks !

Looking at interesting options, has anyone fitted 5007 L494 style on an L320 ?

Can’t see anything online.

The 5007 is a 21" rim and will certainly fit over the 6 pot brembo's, as I ran them on my S/C for a short while before I fitted a set 21" SVR rims. Have you actually the six pot or 4 pot calipers as the 4 pot are quite smaller anyway although the damper block sticks out from the side a little way.
