Wanted to start a thread where we all can put questions about wheel and tire fittment.... This may help all the threads where people ask will this work or fit!!!

My current question is what's the widest tire I can get on a 8.5" wide rim? A 255?
 
#2 ·
255 on a 8.5" should be OK... not sure if you wanna go any wider... then you get the balloon / truck tire effect...

my question is, would 245/45 fit on the stock 18s? or i should say, i know they fit, but has anyone done it to tell me how fat / ballony it looks?

reason i say that is because i had 215s on a 7" rim (instead of 215 on 7.5 for the GS) and the tires looked fat and low all the time, no bueno.,...

PS: Rick, good idea, i was gonna start a similar thread a few days back...

I've read the widest tire on a 8" is 255 but people say you get alot of rolling feeling through the turns....

Also as far as the round sidewall problem all tires do have different wall thicknesses...

Ex my nitto drag tires filled up and held the car up at 31 psi.... I bought these new rims that came with kumhos and I put them to 32 psi and looked flat I now have the kumhos up to 43 psi so they are not flat..... Bolth sets were exactly the same size so deff sidewall has a impact

^ what he says.
if the tire is slightly too wide (and sidewall too tall) for the rim, it will look like a balloon on the sides, unless you crank up the pressure. when i had my PA3s at 32 psi, you could have sworn they were low on air. crank it up to 36 and they look like a regular tire.

and yes, different tires have different sidewalls stiffness

So it's looking like I'm gonna be sticking with my stockers atm, and getting tires tomorrow :/ unless by the will of God I sell those Oakley's today. But, I'm curious of what to look for. I'm running 225/50/17 right now. Should I go wider? my stockers are 17x7.5" with +46 offset. I want to get as much stance as possible, looking into spacers soon etc. And lower of course.

ok here is a couple questions i have, any one who knows the answers please let me know:

I recently put on staggered rims and tires-
18x8 +30 offset 225 45 18 front
18x8.5 +32 offset 245 45 18 rear

I had oem 17 star rims with 215 50 17 tires

1. The hub size is a tad too large in the front. This is due to manually enlarging it. I am working on getting it machined to a specific size and purchasing hub rings. its not super large just a tad. I have some vibrating in the wheels at high speed. Is this due to the hub being a tad off or because of the size of the rims? Should i get an alignment?

2. The oem recommendations for psi is 32 front and rear. But the tires say 44 psi. Should i fill to the tires psi or to the oem specs?

1. the vibration is most likely due to the slightly over-sized bore... a proper maching and hubcentric rings would take care of that... speaking of which, i may have 4 for sale soon ;)
2. the tires probably show the MAX PRESSURE not recommended. i'd do 32-36 to start and see how the tires look, and how you like it...
 
#11 · (Edited)
Yes please don't go above max pressure labeled on tire... Mines up to 42 but my tire says max pressure of 52... And get spacers with a 67mm bore size...
Did you buy the rims and tires new or used

Edit Juhn

225 on a 7.5 rim souls be a good fit what kind of stance your looking for
 
#14 ·
I want a stance that would be similar to the of kchu or neo. I want it to sit a little bit wider in the back, and want wide tires, but.not too wide, so i don't experience that tucked look. I still Need to lower, and once I do I'm probably going to slightly lower the front more than the back.
 
#18 ·
Ok and if ur wanting flush fender or poke I'd say a offset of at least 35 to 20

This was my old rim setup 8.5 from 9.5 rear
It's not much but also not overkill.. Rims were 38 offset

Rear 9.5


It was pretty much a flush fit with the fenders so work your way from this

I've looked at online calculators (somewhat helpful), contacted some members (sorta helpful), so now I can post ask this here:

How about 18x9 all around, 30 offset with 235 or 245 / 35 or 40 / 18 with an 1.5 drop look and sit? Flush with fender? 35 series too low? would a 40 series fill out the fender gap better with the drop?

Appreciate any input and suggestions. I'm looking REALLY hard at a 18x9 with 30 offset. Thanks guys!!

Thanks for the input! So a little stretch you think with a 235?? That's probably what I should go with if I drop it any lower than a 1.5 inch?

That's another question, When I get back to the states, I think I will be selling my set of NEW TENZO springs (in the box) and getting S-Techs.

I really want to know if there will be any fitment problem with an 18x9 rim with a 30 offset with S-Techs or would the TENZOs be better??

Honesty I'd say get your drop done first especially cause ur doing springs then do your wheels and tires so you will have a better guess on what tire size you will need to fill/fit the gap... It's hard to tell all at once... Unless you get coils then you can adjust to the tires
 
#24 ·
This was my car on sportlines with 19's and a 35 thickness tire they were a 2" drop so Im sure the 18's will fit fine On a 1.5
What was the width of your rim? 8.5 or 9? and the offset?

18x9s with 30 offset should be good to go right?

Thanks for all your input :bigthumb:
 
#25 ·
Mine was 38 offset rears 9.5 front 8.5 and yes is say ur good to go but still I'd do springs first then wheels and tires to fill in gaps... You will beable to measure out a closer fit

Has anyone run into issues installing kumho 225/45's on the stock gs 17in rims? Theyre about $20 less per tire than the 225/50's and the only significant difference between the two is a little less than an inch of sidewall height. .8/.9 if i remember correctly.
 
#29 ·
Well going with a smaller sidewall will increase your gap in the wheel well and it will throw your speedo off a little.

Yeah but no more than 1mph as far as I'm tracking (feel free to correct me if anyone knows better). And for saving an extra $80, I can live with that. The wheel well gap will be reduced in the near future. Leaning toward the Eibach Pro Lowering Springs from RRE for that fix.
