Looking to replace my tyres, heard that replacing the 275/40/20 tyres with 275/45/20 tyres give a better ride ?, would I need to have the Speedo adjusted or any problems with the tyre rubbing etc with standard set up ?, or should I just stay with the standard size?, thanks for the advice 👍🏻

I'd be interested in this too...The 275/40/20 feels a tad harsh to me.

275/45/20 is the way to go no mods required and no speedo issues. I’ve been running that size for years. I changed my spare for a match wheel/tyre as well. 2008 G4 RRSport TDV8 current

I have just fitted the 45 profile speedo is now only 1mph out at 70 when compared to the GPS. No issues with access height but not deflated the corners to check if any issues but you wouldn’t be driving it that low anyway.
I went for the General tire AT3 so 50/50 on off road as I’m currently building remote sites up in Scotland and sometimes have to go on site visits... if you go for these the tyre pressures are critical for a comfortable ride but standard settings seem to be the best so far. No uneven warring and good handling on tarmac. Not pushed them off Road yet just a few fields and snow but all good so far.

Ok thanks guys, looking to put a set of hankook ventus st m&s, had these on my last rrs running 275/40/20 tyres, any different in Corning at speed? Thanks

My spare is a 175/80/ r19, so would need replacing? As not much room under the rear to fit a larger diameter spacesaver wheel, recon 15mm before it would foul the box section of the bumper😳

We have the Hankook Ventus 275/45/20 fitted. Great tyre & Much improved ride.

We need to replace our 275/40 20 tyres shortly - if I have read correctly changing to a 45 profile doesn't cause any issues?

I ran 275/45 x 20" for several years, now run 275/45 x 21" and have had absolutely no issues what so ever, the difference in speedo reading is also negligible in fact if anything it is more accurate.

Wow, what a transformation!

I had a set of 275/45 20s tyres fitted this afternoon and the RRS is transformed - the steering feels more accurate, car feels more 'planted' on the road and so much quieter.

Thank you rrsport.co.uk for the advice/help

Sounds like it’s worth doing?
I might do the same when my tyres need replacing.
Just a thought, do you need to inform your insurance as I’m assuming they are changing from original spec? 2016 RRS SVR Estoril Blue

If we all point our RR's in the same direction and accelerate at the same time can we turn back time?

I informed my insurance company (Admiral) who made a note on the policy but other than that nothing else needed to be done.

chaps, are there any other higher profiles that one can fit to the 20" wheels? --
