| I dont agree with james76. My experience of ditching runflats for Toyo Proxes T1R in stock size was a major improvement. Same nimbleness and turn in. Much better overall grip - I found the OEM tyres pretty poor. Biggest improvement is the ride quality as non runflats can absorb bumps more working with the suspension. For me the standard setup is very firm and poor at bump absorption on UK roads (bumpy where I live).
Also non runflats are 25-30% cheaper.
Only downsides for me are the obvious ones (not having a spare, etc).
