Help with picking Rim size

[hcorea]

Okay I finally saved up enough money to buy these rims:
http://www.tirerack.com/wheels/WheelCloseUpServlet?target=runWheelSearch&initialPartNumber=KZX604B&wheelMake=Kazera&wheelModel=KZ-X&wheelFinish=Black+w/Red+Stripe&showRear=no&autoMake=Toyota&autoModel=Supra&autoYear=1991&autoModClar=&filterSize=17&filterFinish=Painted&filterSpecial=false&filterBrand=All&filterNew=All&sort=Brand
I think they will match well with a new red paintjob and black stripe around the edge of my 91 supra.

Anyway I have no freakin clue what size to get;I know my rear tire is 225-50-16 and my front ones are 225-45-16. Does that mean I have to get bigger rims for the back?

Oh and also all four rims are 16x7 37

Just get 17's all around. Wider tires in the back.

For those Kazera wheels, id go with a lower offset if you can.

Are you planning on getting new tires as well? If so i'd go with some 17" wheels. With 8" wide in the front and something around 9.5" in the rear. Staggered setups ftw!

Have you considered something like these? 17x7 front, 17x9 rear

If I were to go for these I would try to email him and see if you can get 17x8 for the fronts; the offsets on those are ok though.

Yes I am planning on getting new rear tires(I literally have no tread left on the rear ones!)
So I can just get four 17'' and I'll be good?

 

[steven89]

well if youre going 17" then you need to get all new tires.

For rim sizes.. well

Check out which wheel fitment you like. Then try to find a wheel size, and offset that you like.

We have a sticky for this...

Nice rims, my car is also sitting on 17'' all around and they're fine. The extra inch of rim will make the car noticeably sexier. I'm sure you'll like it and maybe thank us

 

[hcorea]

Well if I get 16x7 will I need to get new tires? Because my rims are 16x7 stock

If you get the same size rims all around get the same sized tire all around so you can do a 4 tire rotation.

Well I for sure will get new tires for the rear but my dad just bought brand new $300 front tires over summer so I don't wanna spend more than I need to. So then the choices are either I get 16x7 and replace rear tires or 17x7.5 and replace all tires?

Oh and sorry about that sticky but it doesn't help at all. None of those fitments match my rims and nothing in that sticky really explains anything about how different sizes require different tires...

IMO 17s look better, but the choice is yours.

 

[steven89]

Poodles - beat ya too it! =p

If you already have a set of 16" front tires you wanna keep. Id just stick with the stockers till you can afford/get a full 17" setup complete with new tires.
Unless you REALLY REALLY want new rims and get new 16" wheels and stick your old [but new tires over summer] on with new rear tires.

 

[hcorea]

All right than 17'' it is! thanks guys, oh btw the offset it okay right it won't screw up my ride or something right?

 

[steven89]

well the 45mm offset will prob be alright, but the wheel will sit further in than stock.

Like I said earlier, go check out that wheel fitment thread so you can find out what offset you want. Offset is what determines how far in or out the wheels sit from the rotor surface. Its very very crucial that you get an offset you like. Or you might be dissapointed that the wheels dont look/fit like you wanted them to.

18'' or nothing.

No the 17'' are 40mm offset. 3 mm won't look much different will it?

I really like how it looks now so hopefully it'll be good, thanks for the responses!

18'' or nothing.

Good luck running 18s, while retaining a semi-accurate speedometer. Not to mention having lower profile tires; with a rougher ride and higher chance of pothole flats.

 

[ValgeKotkas]

Thanks for the luck, though it's not needed.
1 time check the speed with a gps and you know the difference. Plus, the speedo is calibratable to some extent.
Pothole flats? You shouldn't drive through holes you know...
Rougher ride - hmmm, I thought so too, buuut Get the right tire size (right profile), and even on the roads of Estonia (no, we don't have good roads) I didn't notice much difference coming from sawblades and stock size. (Other than harder to steer due to wider rims, but who cares?)

Supra is quite a big car - it likes big rims (no, I'm not talking about truck-like 20's...).
But that's my opinion. Take it as you like.

I definitely noticed a difference in comfort in between a friends supra with 18s over my supra when i had sawblades. Im on MKIV TTs right now and I love my 3" sidewall. Along with my speedometer only being off by 1-2%.
Roads here in Houston suck! Theres potholes everywhere! haha
But the lower profile tires were my main concern with 18's. The speedometer difference I can deal with.

Ill put it this way; if I lived somewhere where the roads didnt have as many potholes and shitty foundation roads. Id be rockin the 18s.

with lowprofile you have better handling.. that for sure. When I use my sawblades after having my 19low profiles I get a boaty feeling. If you want to by big brake-kit in the future you might wanna concider that aswell.
