So ive been searchin around, and have yet to see a width/offset thread on here. It would help greatly for the people who are thinking about doing wider. more aggressive wheels (like myself.. after i get my car. LOL.), or for people who just want to see what a certain width and offset will look like, doesnt necesarilly have to be an agressive setup... Ive been searchin around as much as possible and still dont know what really fits on a volvo and what wont (with out "minor" mods:oogle:). im thinkin of goin WIDE, atleast 9, or 9.5..

Sooo any interest in getting this going? More info the better (wheel size/width, offset, ride height, tire size, and of course PICTURES.)


edit: i just came across the wheel thread (http://forums.turbobricks.com/showthread.php?t=177609&page=18) but unfortunately it seems like most of the offset specs were left out. which kinda sucks, since offset is a big role in wheel choice..

also willtheyfit.com is a great place to check out when you want to compare what wheels you have now to those you have always been eyeing.

Tell me what you want to use, and I'll tell you what offset. I am the offset thread.

im thinkin about running 9.5" wide wheel.. rolling and pulling is not a problem :)

ET0 clearance on the rear: http://www.pbase.com/towerymt/image/92600835.jpg

ET3 rear, pulled ~1.5" measured at the rear mudflap:

Use narrower on the front. I think ET0 could fit the front, but maybe up to -5mm may be needed depending on wheel diameter and tire size.

ET0 should just barely fit up front if they are 18's. It'd be scary close though, and if they're smaller than 18", all bets are off. I would aim for ET-5 on a 18" or 17". It will handle terribly on the freeway. :nod: 16" or 15" I would go et-10. That would make for a car that is truly miserable to drive.

ET5-ET0 in the rear like Towery says will be good.

and this is why i am redrilling my hubs. 16x7 et+10 front and 16x8 et-10 in back with 5x114.3 bolt pattern.

Any that will fit. Be more specific.

Offset is meaningless without width.

good deal. lol

whats the width your running in the front and rear? also, do 240s prefer a staggered setup? or can you have just as much "fun" in the front too?:lol:

I use the same size on all four corners...for now.

16x8 ET55, 245/45/16 for street. 51mm front adapters, 35mm rear.

16x9.5 ET38, 275/45/16 for autocross. Same adapters.

And I recently put together a set of 15x10.5 ET??, 275/35/15 that fit with 51mm front adapters and 25mm rear adapters.

Front fender lip/arch rolled out into a continuous arch. No cutting/welding done (yet).
Rear quarter panel split from the inner panel, pulled about 1.5" at the rear (as of those pictures above). Since then I cut out the inner panel, bumped out the top a little bit, and rolled the leading edge of the lip/arch out to give more clearance at low ride height. I was able to compress the rear suspension until the bump stop above the pinion hit on the axle housing, and the big tires were not touching the chassis. In practice, it turned out I had to hammer the inner fender a little to keep them from rubbing on the inside. At 9.5 ET3 and a slightly cantilevered sidewall on the Hoosier A6, it's enough room that it doesn't hurt the tire with the slight rub. A street tire would not be as wide and would not overhang the wheel nearly as much, nor would it make as much lateral grip so 275 street on 9.5" ET0 will clear the inside with the axle centered.

Paging Towerymt:

17x8.5 et20 w/ 225/45 or a 215/45

By my measurements it should work, but this is my first wheel fitting endeavor on a Volvo so I look to you for guidance. I don't plan on tracking the car, auto-x, or much spirited driving, it is a beach cruiser and a daily for my 3mi. commute.

What model?

240:
8" ET20 is very close to the strut tube on a 17" or 18" wheel, so an extra 1/4" wheel width on the inside might be too much. 1/4" spacer and it will definitely fit. Without a spacer, maybe/maybe not.

Rear may rub if the axle isn't centered. May still rub a little with the axle centered. Will rub regardless, on articulation. I tried 16x8 ET20 245/45/16 on the back of my daily driver ('92 244) and the wheel wanted to touch the upper shock bolt. A larger diameter wheel or low ride height would have solved the wheel rub. But a slight tire rub at times was still possible. You'll see it and then you can bash it with a hammer. I made it through an autocross without damaging the tires, so it wasn't that bad.

The 'race' car (87 244) got hammered and painted to track the rubbing:

Thanks for the insight, the car is an '81 245. I am sure it will be close up front, I had almost planned on a 5-10mm spacer to get it off the strut tube. In the rear I was planning on adding spacers to match the front fittment once the car is down, axle centered and possibly a watts link fabbed up in place of the panhard bar. More than likely it will be bagged so the Watts link is really the better way to go so it can stay centered over the entire range of travel allowable with the bags.

awesome thanks a bunch, gives me a good starting point. i plan on doing 17x9.5 +30 with a 1in wheel adaptor spacer (25.4mm) so my effective specs on all four corners will be:
17x9.5 +4.6 ET

and i was also lurkin through your photo deal and saw that same pic.. you gotta do what you gotta do! lol
