just picked up a 430 convertible, I'm looking to replace the run-flats that are currently on it because I think they're too loud. I'm wondering if I should get something wider or taller, or stick with the same size and just getting non run flat design oh, I'm looking for something that's reasonably quiet and has a decent handling as well. I live in Florida so snow traction is not a factor. I would appreciate any recommendations thank you so much
I have stock 19in non staggered rims that comes straight from BMW

on bmw 19x8 square set up, i recommend going slightly up-sized to 235/40/19.
10mm more treadwidth and at 26.4" diameter it will provide 0.2" more sidewall for better ride and impact protection. it will also reduce the fenderwell gap by the same (0.2") for nicer appearance.

if you are going all-season, goodyear exhilarate*, yokohama advan sport a/s, toyo proxes 4, falken ziex ze960.

for summers, continental extremecontact sport*, vredestein ultrac vorti, yokohama advan apex v601 or the reknown, michelin pilot sport 4s if you desire and can afford the best street summer tire at the moment.

*what i'd get

listen to this guy, 100% correct

Yep, listen to him. He recommended 235/40/19 for me and that's what I got. I got Yoko Ykxxx? something all season tires non run flat and they have been great. Great handling and no noise (not that I can hear it since I upgraded my amp and play the music loud with the top down)

I didn't get summer only since Ohio weather is all over the place. Once the temperature stays below 40 degrees, I'll switch to my snow set up.
