no good if its a different diameter mrH

if the 22" is a bigger diameter then you don't want to have a standard 21" as a spare

I was going to check, but presumed the rolling diameter would be the same for them all, and the 22" would have thinner rubber?

Rolling diameter of both the 275/45/21 and 275/45/22 tyres is 1.9% smaller than the 295/40/22 tyres.

Thanks Phil. How does the space saver compare?

I assume the reduced size wheel has the same circumference as the 21/22 - i.e. 1.9% smaller than the SVR 22 wheels. You wouldn’t want to drive with odd sized wheels. The TC and ABS would have heart failure.

So my options are tyre sealant or a low loader?

No you need a reduced size spare, which is the no cost option for the SVR. SVR 2018 in Santorini Black.

Forgive me I'm confused with the contradictory comments regarding the reduced section wheel and I've yet to figure out a part number or seen one for sale (can't order as option as bought used)

Confused

I thought I was confused before, but I'm more confused now. Via the new car config, the reduced section wheel seems to be what I thought was (and is widely advertised on eBay as) a space saver.

So what is a space saver if not a reduced section alloy? Maybe links to pics/ options would help put this sorry saga to rest.

My wheels are standard 22 inch with 275/40 tyres and they fit. I am assuming they run on a 10 inch rim. M16 SVD 4,4 HSE with a few extras, Sold R50 , Wife SQ5 , BMW R1200GSW.

Hi,
So a 275 x 40% = 110 + 12.7 for the 22" (half the extra inch to add to the radius
/side wall height) so 122.7

A 275 x 45% = 123.75 for the 21" both sizes can be used and should not affect anything

The 295 x 40% = 118 + 12.7 = 130.7 so maybe 7 or 8mm difference

Get a New 275/45/21 as a spare and only use it if your 295/40/22 are half worn there will only be 3 or 4mm differnce then and your sorted Laughing


It all works in theory but ISTR tyres can vary slightly in size between manufactures for the same size stated Big Cry Corris HSE Dynamic 2016

Always pick up stick in the middle !!

You're on a 9.5J rim.
10J is SVR specific

Its the 295 tyre width, not the OD that prevents the floor sitting down on the SVR 22's
