Wheel / Tyre Sizes

[stablemate]

I currently have my winter wheels and tyres on my L405 Range Rover. Tyre size is 255/55 R20.

I don't think I want to go back to my normal 22" summer wheels as the car rides much better on the 20's, as such I will eventually want to put some summer tyres on my 20" wheels.

Using my reg plate on one of the online quote services brings up either:

245/45 20W Front & Rear | Load Index 103
245/45 20 V Front & Rear | Load Index 99
255/55 20 W Front & Rear | Load Index 110
275/40 Z20 Y Front & Rear | Load Index 106 |


Would any one of these size options fit on my wheels (20" STYLE 5002, 5 SPLIT-SPOKE LR037745)?

It may be a really silly question but my reason for asking is that using one of the online calculators, the different sizes seem to make quite a big difference to the speedo / rolling diameter etc.

Any input would be MUCH appreciated!

Many thanks in advance.

They will probably all fit. Can you take a photo of your tyre pressure label and post it up here? Or have a look in your handbook?

Doh - should have thought of that one

This would seem to suggest that I can only run 255/55 if using 20's?

Based on a quick google, they're 8.5J, so the widest you'll want to go is 255.

May as well look at 255/55, as that would match the winters.

Price was the main reason for looking at other sizes. I had only looked at the "Quick Install" company, and the prices for the 255/55's seemed substantially higher than for the other ones.

However I have now expanded my search and found many different suppliers who are more in line with price for the correct size so it's really become a non-issue. Appreciate the input greatly though and I feel like I've learned something so I suppose today hasn't totally gone to waste! Laughing

I spend a couple of minutes each day staring at tyre pressure labels, they’re very handy.

Get the right size, and the right load index, 110.

Ciao!
