I'm not searching through 346 pages so I'm just gonna ask***8230; What's the widest wheel/tire setup you can run without having to roll fenders?

Car will be lowered(mild) once someone offers a spring. I was hoping to run 18's in the 265/275 range. Think this is a possiblility? Any recomendations on rim size/offset??

thanks

I have a 2021 with 2 sets of Enkie TSR-X bronze panit+powder coat clear coat wheels, and have no issues . My car is stock height and I run my winter set : 18x9.5 +38 with 255/35ZR18'S and my spring through fall set : 18x9.5 +38 with 265/35ZR18'S . no issues on either . The only reason I run the "255" in winter is for less cross width for better tra tion , but if it actually has a noticeable difference in traction is debatable . Honestly , it came down to a great deal on the "265" tires . I really like look of the "255" better .

Hey all -

I ordered a set of 18x9.5 +45 wheels to avoid any fitment woes, but was delivered a set that was +35 offset instead. The wait time was 5-6 months, and it would be another 5-6 months to get in a set of +45s. At this point I have been scouring the internet to see how I can make +35 work - some STIs have the fit dialed in and others look like small tractors.

I am lowered on coilovers, maybe 1 finger gap between tire and fender on the OE setup. I was thinking 245/40R18 tires to pair up with these wheels. Would appreciate any input into if y'all think this setup would generally work. I don't particularly enjoy the poke look, so anything that would help avoid rubbing, with as tucked of a fit that could be feasible. Or should I just give up and wait another 6 months?

Thanks!

Fit is great, no rubbing, no touching.

I drive in Northern NH, VT, and upstate NY. Winter is real, and roads are crap. I'd probably be better off with something in a 255/50 if someone made such an animal, but that wouldn't fit. There is no way the wheels would survive long up here on 265/35s. The Conti's are about all the meat I could stuff in there w/o mods. (those are not scratches on the left door/quarter, something reflected)

Going to a 9.5 and +45 gives you and extra .5 inch each side over center and a 10mm offset difference equals roughly .4 inches (about half of the 1 inch width gain). So in order to keep the inside of the tire at close to stock location +45 is the way to go on a 9.5 inch rim. I wouldn’t run a 9.5 if you only want a 245 section width tire, too much stretch and it looks off. I’m running a 255/40 in the factory 8.5 and it’s about perfectly square but tires vary even though 255 is supposed to be 255. My winters are 245 on a 9.5 but that was all about value, I’d rather have an 8.5 for that tire or a 255 or 265 for that rim but I can’t pass up a great deal. 265/35 fits our cars and looks good, I’d run that with a +45 but most seem to go for the flush look with a +38 or more. I hustle curves and like forest roads too and 245 was fine on the factory rim. Full travel for the rough roads without rubbing and great traction in the curves on good pavement. When I looked for tires recently for my wife’s GTI I saw 255/40 Firestone Firehawks for $108 per tire no shipping directly from Firestone Complete Care so I jumped and put the 245 Dunlop’s that are 1/2 worn on the GTI. Again, value was a major influence in my decision. But it was a win because the GTI feels like a go cart and the WRX pulls your eyeballs out as well as allowing full compression without rubbing.



Hi guys:


For those still reading this in 2022:


I'm not so sure that the math is correct. I believe the reasoning is correct, but the calculations are not. The increased width of the wheel is divided by 2 because 1/2 toward the engine and the other 1/2 toward the fender. So, going from 8.5 to a 9.5 rim = 1" total increase in width, thus 0.5" toward engine and 0.5" toward fender. Therefore, if the offset stays the same, then new center of the wheel will be 0.5" farther out. So, reduce the offset by 0.5". 0.5" = 12.7 mm. Thus, if OEM is +55 offset, the new offset will need to be moved in toward the engine by 12.7 mm making the needed offset of about 42 (42.3 calculated, and rounded down).



8.5" rim = 215.9 mm
9.5" rim = 241.3 mm
242.3 - 215.9 = 25.4 mm = 1"
1" / 2 = 0.5"
0.5" = 12.7 mm
+55 offset moves the new 9.5" rim center-line out toward fender by 12.7 mm, thus changing the scrub radius by 12.7 mm. So, to keep the scrub radius the same, reduce the offset back toward the engine. Thus, 55 - 12.7 = 42.3 mm. So round down I guess and get a +42 offset for new 9.5" rim.



-----------
I took some paper and cut out some wheels to size and marked ceter-lines of rim and marked the offset. This way I can visualize and work with something for real, and not imagination alone.





The problem is that it doesn't work this way as explained above. If the offset and tire size stays the same, the wider 9.5" rim center-line will in the same location as the 8.5" rim because the offset didn't change. The tire will still be 0.5" closer to the engine and 0.5" farther out toward fender. If you then go to +42 offset, then the new rim center-line will be 12.7 mm out toward the fender, thus moving the rim+tire back spacing out toward the fender by 0.5" and thus changing the scrub radius and King Pin angle by 12.7mm.



Scrub radius, from what I know, for what it's worth, should not be more than 5mm difference to prevent any changes in geometry + function of suspension + steering + handling. Thus, there is no way to change the rim/wheel width and then adjust the scrub radius/king pin angle back to where it should be simply by changing the offset because changing the offset moves the center-line of the rim. So, basically if you want the OEM geometry, etc. to stay the same/not be changed or be changed as little as possible, then stay within +/- 5mm of OEM offset. So going +50 is OK.



Anyone have any thoughts?


Ty,
Rob

Hey guys, I know alot of talk on here is for 18", but I do enjoy a meaty fitment and theres a set of CE28N's being sold local in an "S2000" fitment

17x10 +50.

Assuming the center bore checks out do you think theres clearance to the inside/strut on this width and offset, seems the poke should be okay compared to what Im running in the winter currently (17x9 +30)

Was hoping to do maybe a 275/40r17...

Thanks

I think that could work depending on suspension setup. Coilovers should be plenty of room. Stock struts not sure.

I decided to stick with 19s on my 2020 STi and went with 19x9.5 +38 Titan7s with 265/30/19 ps4, RCE SS1 coils and rear LCAs with a little negative camber. Rubbed a lot so had rears rolled/trimmed and fender liner trimmed but still rubbing on hard turns/bumps. The sidewalls are very slim with the 265/30 so any rough road or potholes are white knuckle driving. I love the stance though. I could maybe roll or trim more, add some negative camber and raise it up slightly or do a different sized tire, maybe back down to stock 255/35/19, but I like 265s width. Would even do 275s if they would fit. Anyone have any examples of meatier 19 inch set up on a VA STi?

I managed 275 on 17" wheels on my 2015 WRX (I no longer have it, but it had the STI Brembos). However, offset was 45.

The problem is the rear where I circled. with a 38 offset, you will stick out further than my marginal clearance.

With all this, it was the Falken RT615K which runs a little narrower than other 275 tires...this means your 275 will stick out even further.

You may be stuck with 265 on a 19".

I am going to try 275/35/18 in the next few weeks on the STI I recently picked up. This is the older Brembo, but that shouldn't matter for this discussion. I will be using the Falken RT615K as it runs narrower. Anything else would have to be 265.

Edit: Sorry, I just remembered that I can not upload pics on this forum.
The 275 rubbing is going to be at 2 o'clock of the left rear tire in the picture you posted.

Appreciate the input! I’ve been looking to see if I can at least do a 265/35/19 instead of 265/30/19. Just want a bit more sidewall although 275s in 19” would be my end goal.

your 38 offset will not allow a 275.

this is a 45 offset 18x9 with rt615k 275/35.

camber is -1.5

I may need to roll the rears...even though the rt615k is a "narrow" 275.

Uodate as I finally have all tires installed.

Managed 18x9 +45 275/35/18 falken rt615k+

These tires are a narrow 275, so if you get a different falkon like rt660, you need 265.

we didnt need a spacer up front to clear the ohlins.

no fender mods.

sitting at -1.5 all around until springs settle and I can decide on alignment specs.

I did some hard esses to see if tires rub and hit some bumpy surfaces, but nothing happened.

I still pulled the fronts slightly and did my darndest to pull the rears but I doubt they budged.

Wow surprised you managed to fit a 285! Any fender mods you had to do? I’m looking to run 275 on 18x10 +39 lowered on coils

All I have is rolled rears. Tbh the 295/30 is better. As far as being able to go a little lower. The 285/35 the sidewall is bigger obviously lol.

But ya 275 is easy at you’re wheel specs.

I would say 18" x 9.5 or 8.5 with a 255 tire.

I had 19x9.5 and the ride was made worse. These cars dont like the 19s.

Default What tires should I get?

What tires should I fit to a 18x8.5 +35 wheel? I want a little bit of stretch for the style and so it wont throw off my speedo too much but I dont want a risk of debeading when driving hard on them. Im currently on 16s with a 205/55/16 and I am getting new wheels and looking for advice on tires.

225/35/18?
215/35/18?

Any help is wanted
