Perfect wheel size on Celica Options

[AnaXyd]

I have a Celica AT200, and is currently looking for some new wheels and tires. What is the perfect wheel size on my Celica? I am planning to lower it too.

Any answers will be appreciated!

rule of thumb. if the automaker put it on it is probably the best best. 15's are stock. 16's are ok. anything else is really for show and not for performance.

your rule of thumb isn't very good. Most things automakers put on are for safety /detuned and are no optimal.
They are designed for a specific market.

If that was the case there would be no modding at ALL required.

i understand your point. i'm just saying that toyota put 15's and 14's on the 6gc. so that car is built for that size rim. you can go bigger, but on cars especially for rims what is comes stock is what is meant to be. oil and rims are two examples. when you go with bigger rims the speedometer is screwed up and heaviness is also a factor. i won't go much bigger then 16's or 17's if you want performance. but if you them want show go bigger.

As a rebuttal,

You can put larger rims on the car - it is the rolling diamter that influences the speedometer - yes it may be hard to get perfect, but will not be a big difference - maybe 3-5mph IF you are attempting to match original rolling diameter.

As for what it is meant for statement - once you change your springs/sprint rate that disproves your reason. With higher spring rates you are no longer in the " what it is meant to be" category if you were to keep the rims/tires stock.

As for weight the stockers are lead coffee cup coasters - many of the wheel/tire combos available are lighter than stock - though at the extreme end of the spectrum you would need seriously spending 18-19" rims to match the weight of stock - though this is also effected by rotational mass and where specifically the weight is that has the larger effect on performance, but that is a discussion for another time.

To determine rolling diameter and changes to speedo - there are several online calulators that will compare stock to the proposed wheel/rim.

As for the OP question - I am a big fan of 17s on the 6gen - all the 6gens I have seen around with decent rims (Focal/cheap crap excluded) that are 17" just seem to fit the profile/lines of the car so well. Also leaves a little meat between the road and you so ride is decent.
