Tyre sizes

Post by SteveT » Wed Mar 24, 2021 10:42 pm

Hi, can anyone advise what tyres are fitted to the MY21 20” and 19” wheels please? I’m after the sizes not specifically the brand.

So I managed to confirm that on the 19's the size is 235/55R19 and on the 20's they are 245/45R20........in terms of difference, the R19's have a 741.1mm diameter versus the R20's 728.5mm so the R19's actually fill the wheel arches more than the "larger" R20's.

Also, the sidewall heights are for R19's 129.25mm versus the R20's 110.25mm so the R19's have about 19mm higher sidewall or 14.7% more.

I would prefer the higher sidewalls and larger overall R19s but prefer the R20 wheels....what a 3rd world dilemma....

Are the 20's any more of a wheel damage risk and much of a harsher ride than the 19's would be, any opinions gratefully received..

I think those are the sizes for the 'old' DS, my 20" are definitely 245/45R20, I think the new DS is 235.

Never had a problem with wheel damage because they were 20", the one time I did touch a kerb it was so high and leaning outwards that it would have scraped a 13" wheel!

You might feel a slight difference between 18" and 20", I would say barely detectable if at all with 19" and 20" which was certainly the case on the 19" curtesy cars I have had when my 20" was in for service.

Thanks for the feedback, maybe someone with a new MY21 can check what they have fitted?

The online manual shows which wheel/tyre sizes JLR recommend (IIRC you need to look for pressures rather than the tyres as such to find the tables).

I've never had a problem with the 245/45/20 standard ones on mine. Little difference in ride compared to 18" (have never driven one shod with 19s). No damage apparent after varied usage to date.

Taken both down the runway at speed as well as across fields. No apparent difference in performance to me on concrete, asphalt, grass or tractor tracked field.
Vehicles are tools but the gloss black 20s do look a bit nicer than the silver ones when parked.
