Default Tire choices for a 18x8.75 wheel?

Alright im seriously considering pre-ordering the new xxr 527's but the size/offset is kinda throwing me off. Im looking at the 18x8.75+20 which would give just about the same amount of "poke" a 18x10+30 wheel would give according to an offset calculator. My question is would a 225/40 give the right amount of stretch for fender clearance? Any input on these wheels?

The 35's don't do it for me. I had the 006's last year, 18x9.5+35. I liked the way they fit just not the way the lip curved. I wish there was like a demo car they used for fitment pictures...

Yeah i hear what you are sayin. but i think the lip may be the same on this wheel both offsets, as they do not use the pressed in s/s lip.

its just a +20 will give you issues as stock is a +53

it should but nobody will know but you cause we don't know your ride height, fender mods, camber specs, etc etc etc...

odd size because hes buying some cheapo XXR wheels.

225/40 on an (well lets just round up) 18x9 +20 should be ok. its a 6mm difference of effective offset....although it still looks much different than a 10" wheel. Rolled fenders and it should be fine with that size. Maybe even a 215/40, if you want to play it safe.

how did you get 006's in an 18x9.5? those were only offered in 5x114.

The 006's were on my old S14, not my subaru. And I buy "cheapo" wheels cause i have better things to buy then a set of 1500+volks, advans, etc. And im on megan coilovers with access to a fender roller at anytime. Camber can be adjusted as needed also...BUT if either a 225 or 215 should work im good. Its just kinda hard to imagine the amount of stretch on a 8.75" wide wheel.

just imagine it the same as a 9" wheel. the difference in stretch will be very minimal.

If you get a wheel that wide and only run those size tires, well, you'll get what you've got coming.

Gosh am the same way!!! I will rock "cheapo" wheels any day if they look good, don't fall apart a year later (seen pictures of bent/broken Volks, Advans, ect, so they break too) Rather spend my money elsewhere, again it's a Subaru... Not a GTR, Ferrari, Lambo or High-end vehicle where I would see you would "HAVE" to spend the money on "real" wheels.

As people will tell you, each brand of tire streches or sized a little different. Personally I would go with a 235/40s, if you seriously want a good streched look, then 225s will be better. I was running Falken 225s on my 9" and they were streched a little too much for my taste. Just seriously counts on how much of a stretch you want.

^^ with that size wheel/offset, he wont be able to run larger than a 225/40 unless he wants to start pulling fenders.

Yeak OK guy

But i honestly believe theres no point in buying expensive wheels for my DD that only has a 5 mile one way trip to work and back lol. And im pretty sure im gonna go with a 225. the 215's would be just a tad too much stretch for my liking.

Well, it just doesn't make sense to me to mod a car to perform worse. Not only that but you will be replacing bent wheels over time. XXRs bend. They always do.

I've seen bent te37's, professors, RGII's and a couple others along with the rotas and XXRs. Just because the price tag is heavy doesn't mean its indestructible. And like i said, its my DD....cant really "perform" in that 5 mile drive to work lol

I think you're missing the points... XXRs are known for being very weakly/poorly constructed. And you don't need to go flat out for your entire 5 mile commute to notice the difference in performance.

well i guess i can chime in. I've had a set of XXR 502's. had them for a good 9 months. no bends, no cracks, no drama and i've owned everything from enkei's to rota's to bbs'.

tho it might have to do something with the smooth socal roads...

anywho, i was looking at these and must say xxr has been comin up with decent looking sets in the past couple of years (mainly the 521's and these). i just wish they would've come out with the 521's in silver (18x8.5 +40, 5x100). but ya, can't wait to see these on. looks to be a good looking set of wheels. my only gripe is the weird ass sizing nlmotoring puts up.

edit: yea, optimal tires would be 225/40's to stretch.

Yeah you should be fine with the 225/40's , you will most likely have some fender rolling, but should be minor. I have an 04' with Megan springs dropped 1.5 all around which ended up being more around 1.75 after measurments. Here are some pics of my XXR 522's 18x8.5 48offset with 225/40 18's Good luck, check out discounttires.com I got my 522's for 470 shipped total cost from Cali to Florida. Good luck

Tired Stretch

We have 5 shops all in Chicago area. All Light weight wheels bend easily.Some of the top brands seem to be the weakest.

i've never bent a wheel and i drive through DC all the time. 18" ssr gt2s, 17" rota dpts, 17" enkei rpf1s, oem 17" bbs wheels. i guess it's about time i put a set of volks/advans/works to the test

i still wanna know who at XXR decided to make an 8.75" wide wheel

225s should fit with only a roll in the rear, but why wouldn't you go with the +35 offset? If you did, you could fit a 235-245 no problem.

The 8.75 with a 20 offset was made to give a lil extra stretch to say a 225 tire and have a more aggressive fitment without being super wide....retarded....yes. Like theres a 6mm difference from the outer wheel lip to the fender with the 18x8.75+20 than a 18x10+30. And the 35 offset is weaksauce imo. If it was a 10" wide maybe but 8.75....no. And thanks for the pics guy. They really helped

ya slam a strut suspension car that much and you end up with no suspension travel left....so ya ride the bumpstops all the time

ya slam a subaru that much and all the suspension angles get real bad and you end up with a car that handles like an old rambler

ya increase the wheel/tire weight that much and you kill the acceleration and handling even more


and on and on and on


do ya just wanna look k00 and enjoy looking at the car or do you wanna have fun driving it???
