Default 245 or 235 tires on your wagon? (wagon-wheel fitment)

There's a lot of conjecture, expert speculation, noobgurgitation and a few good reports about whether or not the fatter meat will fit on a WRX wagon at all, especially if its lowered.

Been following that great thread started by omahasubaru in 2003 on lowered wagons with 225 rubber. Now here's a place for us wagon drivers to report on our 235's and 245's.

Searching and deciding and finally shopping, I really appreciated posts that had all of the information below. Wanna lend a hand to your wagon brothas and sistas? Put it all down.

wagon MY: 2005

rim size: 17 x 7.5

rim offset: +50

rim brand & model: SSR Competition

tire brand & model: Michelin PS2

tire size: 235/40-17

tread (actual patch) width: 8.5"

camber adjustments: none

suspension: Perrin rear sway bar and end links / Espilir springs / (Cusco CF rear strut tower brace)

lowered?: 1"

fender rolling?: no

rubbing w/o load?: no

rubbing w/ load?: don't know, will report... I don't even like extra keys or spare maps. No problem fully fueled!!

(handling /gearing): noticed a slight gearing advantage in the low end with the shorter-diameter wheel (rim + tire). Handling? I jumped from 205's to 235's, so with the narrower profile and the fatter tread, I'm drivin' a new car! And the Michelins are great on wet and dry.

It'd be great to hear from BIGSKYWRX, abaxter34, OedipusWRX, BlkWRXWag, and RogersWRX.

(handling /gearing): Crappy, these tires suck because they are all-season. If you autocross then don't buy these tires, they are not sticky enough. Gearing is a little taller due to my choice in tire size.

Didnt notice any acceleration increase, but who knows. I would highly recomend These tires to anyone with a wagon, great dry grip and much better performance vs stock. Low on road noise (but I do have straightpipe so cant hear much over exhaust).
I can't believe this doesn't rub. +45 offset and 235?

Just cuz I'm crazy I'm gonna be trying 245/40's on my wagon. I'll report back here once I do. I don't think that they'll fit, but since I haven't seen anybody step up to the plate on this one yet I figure I'll give it a shot.

Most likely the Kumho MX, as people have had decent luck putting them on 7.5" wheels and they're cheap. (Yeah, I know it's outside the wheel specs... but after reading up on it a bunch it's doable.)

I would have done 245/40 on my car if I had the money. The money was the only reason why I ended up putting 235/45 on my car. I think you'll be fine.

mrn98, I believe you.
I wonder if the there is better clearance in the 04+? I have ridden in 02-03 wagons with 225s on 48 offset and heard it rub.

I want to try some 235s on stock STi wheels on my car. Maybe after some more post and my 070s wear out.

Sounds cool, Salaki. It's great to have buddies to loan you stuff for fitment decisions. Let us know!

In my original posting I meant to put 'tread width' instead of 'section width'... just edited in the change. Manufacturers are moving away from publishing tread width 'cause it'll vary with actual inflation pressure and load.

It'd be great if wagoneer posters could take a tape measure to the 235 or 245 you've mounted on your ride and inflated to your normal setup -- and let us know your actual-patch tread width along with the other stuff.

When we're pushing fitment to its limits, we gotta look at shoulder shape. I don't know any way to report that objectively other than to compare section width to actual-patch tread width.
235mm = 9.25 inches
245mm = 9.65 inches
The 235/40-17 PS2s I'm no-rub runnin on 7.5" rims at slightly above stock inflation are coverin a 8.5" patch of tarmac... not too round but less aggressive than some rubber I've seen.

Would a 235 or 245 tire mounted to an 18 inch wheel have more consistent tread width because of the lower profile sidewall or is it still going to vary significantly by manufacturer?

The reason I ask is because I want to put 18's on my Saabaru and wouldn't mind a more significant footprint than 225.

Salaki - it would be interesting to see if your friend's 235's and 245's fit your saabaru before using your fender rolling kit.

You will have a much better selection of tires with a 17" wheel than the 18". Take the word of a man who bought 18's and sold them for 17's... me!

Taking delivery of the car next Tues after long weekend
Soon after that, I will actively work on the Saabaru and will post everything up..

I have 245/40/18 w/ 18X8.5+48 on my STi (tall tires-wrong size but okay for daily drive). I can try to test fit these bad boys onto the Wagon if you want to see but I probably will experience major rubbing that probably can't even fixed w/ fender roller but I'm curiosu and let's see..

i'd be interested to see if these rubbed without so much negative camber

say, -1F / -1.5R ?

I have had -1.5 on the rear and they fit fine. There is more clearance at the front, so I imagine you would be ok. In fact, without camber plates or adjustable lateral links, -1.5 is all you can run on the rear. If you try camber bolts, any extra camber will cause the tire to hit the strut.

ka mano,

How do 235/40-17's feel on a 17x7.5 wheel? Much sidewall flex that you know of? Any problems in general?

Thanks,

Supremo

Default Howdy? I haven't heard that since my tender years in Oklahoma. Same to ya!

I've had zero problems, the sidewalls feel stiff and I love taking sharp curves without breaking traction.

It doesn't give the appearance of the tire being jammed in there, either.

Just updated my post above as promised.
17 X 8 +48 - 245/40/17 fits fine...

Also another crazy attempt I did:
245/40/18 on 18 X 8.5 +48 - temporary fitment last time.
Mid Major rubbing in the rear (not to fender lip) but to the rear bumper.
If I really leave it on as it rubs then I'm sure it will make little by little cuts on the rear bumper and at the end, the tires will cut it like "professional".

Congrats on your wide patch. Looks like you and BlkWRXWag are the only posters so far with 245s. Your 'Saabaru' and STi are lookin fine! Are the 911 and the other cars yours, too?

I'll list mine even though they read "225"- they are the oe S2000 rear fitment Bridgestone S02's- they are pretty wide for a 225. The section width is 9.2, the tread width 8.5, for comparison the following 235/45/17's list RE050's 9.2/8.5, Goodyear GS DS 9.3/7.9, PS2's 9.3 (no tread width listed. They are closer to 235 than 225.

wagon MY: 04
rim size: 16X7.5
rim offset: 46
rim brand & model: Volk TE37
tire brand & model: Bridgestone S02
tire size: "225/50/16"
tread (actual patch) width: 8.5
camber adjustments: front -2.2, rear -1.5
suspension: STi pink wagon/v8 wagon inverted struts
lowered?: ~ 15mm
fender rolling?: yes- thanks to salaki for the roller
rubbing w/o load?: No
rubbing w/ load?: No
(handling /gearing- gearing is oe, handling is wonderful- very sticky street tire, very stiff sidewalls

I think I still have some room to "play" , I'm going w/ 16X8 rims and R compounds next season- I think I'm going to try Victoracers in 245/45/16- then again I may play it safe and stick w/ 225's- the Victoracers are also on the wide side of 225- the additional 1/2" of rim should net me an additional ~ .2" of tire width
