Hi all,

I have a 2015 SDV8 405, and I’d like to fit the biggest off road tryres I can with the smallest possible diameter wheels…

Could someone advise…

Thanks

The smallest readily available size rims are 20” to fit over the brake calipers. Think there are some 19” that would fit but not too sure on that. I’m running 255/55/20 General Grabber AT3’s.

Thanks!

255/60/r20 from a new defender fit the L405 ( at least the Pirelli all seasons do) V8 or else ...

Hi Fisha, do you have the Defender alloys fitted to your L405? If so, do you have any pics? 2019 L405 SDV8 Autobiography

Quite a few owners have fitted 275/55R20.

Just a word of caution for big tyres... The other day I had a combined height sensor and airbag fail and the car dropped to it's bump stops. I was able to drive a short distance to a safe pull over but when I was fixing it I noticed a bit of rub on the arches on my slightly oversized 255/55/R20 so I reckon anything bigger may have rendered the car stuck in the road? 2012 TDV8 Vogue (L322)

Some pictures … I actually quite like them. They have a slightly wider offset, which counters the smaller rim size looking lost in the arches. I’ve not noticed rubbing as yet. Makes for a nice smooth ride compared to the 22” rims I have.

285/50/20 work well and are probably the largest you can go risk free without rubbing in all modes - plus you can get a spare in the tyre well - any bigger and it’s very unlikely you will 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

I put these on mine after sourcing some rims and they fit well. I have also sourced a 20inch spare rim but have left the 255 55 50 tyre on it as it was very close in diameter and fits in the spare wheel well. I wasnt sure the 285 would fit there in terms of the height and it may protrude to high for the trunk cover. Did yours fit ok?

Yes - just - Cooper AT3, 285/50/20, that was on my previous L405 - pre facelift - not tried on the latest one, just left the std spare in as it’s a space saver and there’s a foam infill beneath - I’ve never needed to use a spare on a RR in at least 20 years - think the last time was on a Classic in 1995 - now I’ve just given it the kiss of death and jinxed everything 🙈😂

If it’s any help, I also kept a thick Collins Route planner map in my boot stored on top of the spare and the boot floor still closed ok - if anything I suspect the diameter was the limiting factor before the height / width 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

Thanks for this. Admittedley it was a quick look but the stock 275 22's looked almost flush to the top of the trunk floor. I think I'll do similar to you and just leave the 255 55 20 rim and tyre in there as a backup. My OCD will have me respraying the spare bla bla incurring a bunch of cost for little gain. 2017 L405 AB SDV8
