225/50 R tyres on a 6" rim?

[Sheldon McIntosh]

I've been running 205/50 R15 Yokohama R types on a 6" rim, but have acquired two 225/50 R15 Dunlops.  The tyre people I spoke to, and the websites I looked at, say that for a 225 a 7" rim is recommended but a 6" will suffice, but they are probably not taking into account the extra stress of turn one at PI at (insert current exaggerated speed here)....km/h.

Has anyone used this size tyre on a 6" wheel on the track?

ive got nsome 225 on my factory 15inch rims and they work fine

Sure they will fit on but I would not do it. 7" minimum for 225's IMO.
