I have a RRS 2012 autobiography . It has 255/55/R20 110Y tyres on. Everywhere I look for new tyres are saying its the wrong size tyre for my vehicle ???
Any thoughts ? the ride seems fine ....................TT

275/40/20 is the official standard size.

Someone before you has fitted tyres with a deeper sidewall. Many go for a 45 profile for comfort. Kev

MY2010 L320 RRS HSE 3.0 TDV6 in Stornoway Grey

Ah ok thanks, They will be ok to get the same size then ? i dont want to mess up the suspension or anything!!!!????

I think 255/55/20 is either the Disco 4 size or someone has fitted RRS2 sized tyres to it by mistake (I think RRS2 uses 255/55/20). 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Maybe, i havent had it long so no way of knowing. The ride is nice, quite happy with it

Before you go for 275’s make sure the wheels are wide enough for them,yours might be complete wheels from a disco that someone has fitted & they aren’t as wide. Andy.

Just fitted another set of 275/40/20 to my MY12, I looked at 45's when changing yet stayed with the stock profile. Had the geometry set again, wow what a difference! 2018 Telsa MS

Im quite happy with my 255/55/20 to be honest, may just stick with them I think

255/55 x 20 110Y is a Fullfat size tyre as well, fitted to a 8.5J rim.

Cheers Col, weird why they have fitted them on mine They look good so I'll leave them on I think, as long as it's not doing any harm..

255/55 was the standard size for ZA, not sure why.

It definitely rides more comfortably than the ones with 275/40 or 45 that I've driven.  --

Thanks Naks , its good to know. I didnt think it could get better

Also a thing to remember is your speedo will not read accurate unless its been calibrated with new wheels.Put the sizes in here & it will give your the speeds ect.

255/55x20 is MASSIVE!!!!

275/40x20 would be standard, equivalent upgrade would be 255/50x19
