Deciding between some new wheels, input?

[RDKamikaze]

The weight part was more for sarcasm, but thanks for the concern.

I looked at the 20" rims today, but they wouldn't fit. How in the world do I get them to fit, do the tires have to be really low profile? The tires kind of weren't as low profile as they might have to be, but they kept hitting on the strut.

Man...you don't figure it out yet with all the thread on the subject...anyway...you have to keep close to the stock overall diameter (wheel + tire).

For this you have to calculate tire (sidewall X 2) + wheel.
For that you have to use the tire spec for 20" the best option is 225/35R20
then sidewall = 225mm*0.35 = 78.75mm * 2 sidewalls = 157.5mm (mm/in = 25.4)

it gives you 6.2 inches of sidewall in total + 20 in for the wheel so your overall diamter is 26.2 in and sotckies (215/55R17) are 26.31 in


You really need this tool to help you out.

With all that says...you have also to check the offset of the wheel to avoid rubbing.

There is an other tool to help you figure it out easily.

I use 8in width wheels with 40 offset (it'S the same spec as TRD wheels if you want to compare with)

^^ I love that tire calculator. I have the same site bookmarked. Nice post Sebas.


RDK, you really need to do a little research on tires and wheels before blazing forward making a purchase. This is not a decision to take lightly. Based on your comments with the 20's, I guess you were not expecting the tire profile to be so low?

Sebas' posting is correct. You must keep the same tire circumference (or overall diameter) to ensure proper fit and reasonable speedometer readings.

I recommend you use the calculator to find the attributes of the stock size and work backwards to find 18", 19" and 20" tires in the same outside diameter. Then note the tire widths that are limited by your new wheels. Lastly, take into account the offset in the wheel you are selecting.

I'm concerned you will get 90% into another deal and have to back out because of a no-fit issue. (Or even worse, get stuck with wheels and tires you can't use. ) Personally, I would have been pissed if someone committed to buying my wheels and then backed out after he mounted them on his car. (That seller was being very kind to you.)

If you have specific questions, fire away. But we're not going to do all the work for ya. (I think you need to read up and struggle through it a little so you can gain the experience.)

If all else fails, find a setup that another SG has and copy it.

Good luck.

SEARCH man SEARCH already!

I have personally posted SEVERAL threads about various tire/wheel calculators already - as have others...

... and the list goes on...

You have even posted this question before and we've answered it in detail (check out that second link above). You need to go back and read through your own posts and see what people have already told you instead of double/triple posting here looking for the same answers over and over.

Thanks for the help guy, I hope I can get it fully from here. The 20's wouldn't fit because the tire size was too large, and I'm starting to understand about them more. I never was good with the whole wheels/tires combo stuff, so I honestly don't even know what the tire numbers mean other than the last one that tells rim size.

Sebas, what size wheels do you have in that pic, they look nice!

[kingkakyle]

sebas got 18s ^ ^

[RDKamikaze]

Wow, I'm assuming it's lowered too. That looks like a nice setup, I am actually considering 18s now too!

I'm still working ont he research tho. What are the tires on that car? Could they be 235/40/18 by chance?

Don't worry, I'm working on research now! It's still tough not knowing the numbers for the tires though, could somebody help me with that? I don't know what it's called and google searching isn't helping

What are the stock specs for the 4cyl wheels? I know they' 16", but that's it. Offset and width are unknown to me.

[kingkakyle]

sebas is running Yokohama AVS ES100 225/45R18

235/40/18 tires are pretty rare....not many companies make that tire size
i know for sure that kumho ecsta SPT come in that size....haha
and yes sebas is lowered
for ur stock rim specs go outside to ur car....it should be written on ur tire and rims

o and just an fyi ur looking for specs on a SE rim....cuz i have a 4cyl sport and i have the 17s stock

[RDKamikaze]

Gotcha thanks kyle for the help. I won't have to take the wheel off to find the offset, will I? I know the aftermarket rims have the specs listed on the inside of the rim.

And the fact that those other tires are rare, is that good or bad? Also, does that make them bigger or smaller than sebas' tires? There's a guy selling some 18's with that tire size locally.

[kingkakyle]

overall they will be smaller than sebas tires....id say stick with the 225/45/18...they fit the best but im not sure since im comparing that to my stock 17's go outside and look at ur tire size its writen on the tire....that wuld help out much more
being a "rare" size tire just means u have less choice of tires

[Sebas007]

Yeah I like my setup but if I were you I would go with 19's. If you like my rims (Spyn SVS) then NAD Wheels made a 100% copy of it named NAD 6...offered in 19's and 20's

http://www.nadwheels.com/


more important is too lower you ride...I'm using TRD spring...but I would consider Tein C/O.

I went with 18's for some reasons but the more important one is road condition here in Quebec are really bad comparing to yours, espacially Arizona (no underground freeze/thaw)

You're scaring me when you tell that you don't know what the numbers on a tire means...not espacially because you don't know that...because google knows it and just wait you to ask him. If you learn to learn yourself things...you'll be a winner.

Also...not because they are 18's they will fit...you have to check bolt pattern 5X4.5in or 5X114.3mm

Please use the tools I just post up in the page and read just for 10 minutes the explanation...you'll figure it out.

For this summer I'll buy Toyo Proxes 4 (I was hesitating between those and Toyo Proxes T1-R). My Yoko are now doomed to be used on 1/4 mile drag raceway...really nice tire but they last just 1 summer...so I'm hoping with those Proxes 4 and also being less "agressive" driver will make last my tires more then 13000 miles.

Good luck !!

As stated in the various tire calculators, a 225/45/18 will be smaller than the OEM dia and your speedo will be off. 235/45/18 is closest to the same dia.

Yes Painter...but with 235/45R18 you will have 10% of the choice you may have with 225/45R18. A difference of +/- 3% is all right

Best pattern for best choice and best fitment...in my opinion

225/45R18
225/40R19
225/35R20

[RDKamikaze]

I finally found the right google words to search with! I found this great site that explains and gives detail to each number on the tire. Here it is, I'll share with all!

Made my own way with the 17x8 OZ NOVA's on my gen 2.

Off-set is 40, same as TRD 18x8's.

Running 225/50/17, planning on 235/50/17's next change. (Potenza RE960 AS Pole Positions)

TRD spring drop.


Very happy with my set-up. C/O's or superior struts would be in order later...


One of those rims pictured earlier reminded me of the waffle irons at Country Suite Hotels...
