Is anyone running 275-55-20 tyres on their L405?

Any rubbing issues? Will the spare wheel still fit in with this size tyre fitted?

Thanks

Thanks,

I've been playing around with a tyre size calculator, the width of a 275-55-20 tyre is the same as the 275-45-21. So as you say, that won't be a problem. The diameter might be though?

The difference is only 9mm in the radius - not 18 which is the diameter - a lot will depend on the manufacturer of the tyre - my 285/50/20 are far taller than regular 285/50’s as they AT tyres with very deep tread and don’t accord with the normal size range of that tyre - I would suspect the 275’s will fit ok - if anything they may just catch on full lock.

If you can get the manufacturers circumference from their spec list of your chosen tyre I can measure mine here and that may help. Mine fit fine and also in the well - just 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

I'm a bit nervous about off road use this winter with the Pirelli Verdre All Seasons I have fitted. Although I didn't really worry them last winter, but then the only really muddy sections I drove were pretty much flat.

I'm not a fan of General Grabbers and Duratracs are too aggressive for my needs, so I was considering fitting a set of these for the winter:

I'll see if I can get some precise measurements.

That’s what I have Cooper AT3 in 285/50/20 - these are my winter tyres for the shooting season and summer are 285/40/22 on Turbines. Why not just go for the 285/50’s and save any hastle - they fit without issue both in the car and in the tyre well. 2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

According to the Cooper website the AT3 4S isn’t available in that size:

Not sure what the 4S stands for - mine are AT3 Sport - there’s a piccy on this thread - last post on the page :-

This is the link to the SUV/4X4 tyres from the Cooper U.K. website:

I couldn’t see any of the AT3 variants listed in 285-50-20

The 4S I assume stands for 4 seasons. I think that they may also be 3PMSF stamped.

What about Goodyear All-Terrain Adventure? They’re OE for the new Defender.

Yeah, they’re very much on my radar and available in 275/55/20. With Kevlar reinforcement in that size as well. Not all sizes have the Kevlar.

10 second google - the Coopers are listed here for sale, although they appear currently out of stock it shows Cooper are still making them in that size :

Thanks. I also found them for sale (shown as out of stock), but my concern was more that Cooper had stopped manufacture or U.K. supply. I wanted to avoid buying a set and then find in the future that I can’t replace one due to them being no longer available.
