First of all, what is your rims width? Coz if smaller than 8jj then you can throw the 245 option out of the window, but if bigger than 8.5jj then can forget the 225 option.
If your rims is 8-8.5jj then between the 2 option the 225/50 is more comfortable given the same tire. Having said that though, if you use 225/50 tires with harder sidewall vs 245/45 with softer sidewall then the 245 might be more comfortable or about the same. 245/45 will look much nicer though cuz wider and not so ballooning.

QUOTE(wayfeel @ Jan 10 2021, 07:26 PM) Haha totally forgot rim width . 7.5jj....olin. so many technicalities n physics involved Appreciate the time to explain for my affirmative. If narrower than my stock 235 is safely acceptable then 225 50 it will be ....since 7.5jj cannot go 245 as well... Out the window abt looking good wit tires lol not too care abt that dept lol reason why i was still sticking wit 17'' Ur BRZ use 235 40 18? 235 and 225 is almost same tread width so minimal difference. Some 225 which have wider/more square tread width can be as wide as a narrower 235. I don't have a BRZ. Quazacolt has one. |

I always like my air around 240 The improvement of comfort i believe due to newer tires (softer compound compare to 5yrs old hardened oredy) , origin of country made, and definitely the taller tire profile 50 is way better sitting It's further improvement in comfort also because you moved from UHP Potenza with harder sidewall to more comfort oriented Toyo touring tires. |

QUOTE(zeng @ Feb 16 2021, 01:40 PM) Sorry, late to the party . Isn't a rim size as small as TS' 7.5J within range for a 245/45 R17 tyre ? I know TS has selected a 225/50 ...... just for clarification sake . Nope, minimal for 245 is 8jj. Minimal for 235 is 7.5jj. |
