E70 X5 40d - Standard to RFT tyres (bigger wheels)

Sounds stupid as many go otherway around from RFT to normal. Mine x5 came with 19 inches all around. Big thick rubber, looking underwhelming on such a massive beast. Very comfortable ride though.

I am looking for 20" or 21" wheels and most of them on used sites are RFT ones! Would you guys do it? Swapping standard tyres with 21" RFTs? Will it be too bad on ride quality?

Also would 21" on RFT make that bad compared to 20"?

Must add mine is 7 seater which means no spare. Puncture is a non-diy breakdown.

There are many makes of tires that are Run Flats. (RFT)..they are not all equal.

People are foolish when they think the choice is "RFT or non-RFT"...

Finally, you can buy a donut spare and only carry it when you can. Or keep a spare tire in the garage, in case you damage a tire. Then you can replace the wheel./tire while they find a proper replacement.

great, if puncture is not a concern what about ride quality between rft and non-rft? those who change they do say they feel a difference, could be placebo.

Some manufacturers have poorer ride on their runflat model.

IN MY OPINION, michelin runflats DO NOT have much at all of a tradeoff- especially on an SUV.

I run PS2s on my M5 and 996TT..I would NOT run a ZP version (rft) for those cars (yes, PS2 is available in a ZP)...but on the X5, the Latitude ZP is a fine tire.

Just dont assume every manufacturer has the same tradeoff....
